EduTech Australia 2015, Day 1, Session 2, Higher Education IT Leaders #edutechau

I jumped streams (GASP) to attend Mark Gregory’s talk on “Building customer-centric IT services.” Mark is the CIO from my home institutions, the University of Adelaide, and I work closely with him on a couple of projects. There’s an old saying that if you really want to know what’s going on in your IT branch, go and watch the CIO give a presentation away from home, which may also explain why I’m here. (Yes, I’m a dreadful cynic.)

Seven years ago, we had the worst customer-centric IT ratings in Australia and New Zealand, now we have some of the highest. That’s pretty impressive and, for what it’s worth, it reflects my experiences inside the institution.

Mark showed a picture of the ENIAC team, noting that the picture had been mocked up a bit, as additional men had been staged in the picture, which was a bit strange even the ENIAC team were six women to one man. (Yes, this has been going on for a long time.) His point was that we’ve come a long way from he computer attended by acolytes as a central resource to computers everywhere that everyone can access and we have specifically chosen. Technology is now something that you choose rather than what you put up with.

For Adelaide, on a typical day we see about 56,000 devices on the campus networks, only a quarter of which are University-provided. Over time, the customer requirement for centralised skills is shrinking as their own skills and the availability of outside (often cloud-based) resources increase. In 2020-2025, fewer and fewer of people on campus will need centralised IT.

Is ERP important? Mark thinks ‘Meh’ because it’s being skinned with Apps and websites, the actual ERP running in the background. What about networks? Well, everyone’s got them. What about security? That’s more of an imposition and it’s used by design issues. Security requirements are not a crowd pleaser.

So how will our IT services change over time?

A lot of us are moving from SOE to BYOD but this means saying farewell to the Standard Operating Environment (SOE). It’s really not desirable to be in this role, but it also drives a new financial model. We see 56,000 devices for 25,000 people – the mobility ship has sailed. How will we deal with it?

We’re moving from a portal model to an app model. The one stop shop is going and the new model is the build-it-yourself app store model where every device is effectively customised. The new user will not hang out in the portal environment.

Mark thinks we really, really need to increase the level of Self Help. A year ago, he put up 16 pages of PDFs and discovered that, over the year, 35,000 people went through self help compared to 70,000 on traditional help-desk. (I question that the average person in the street knows that an IP address given most of what I see in movies. 😉 )

The newer operating systems require less help but student self-help use is outnumbered 5 times by staff usage. Students go somewhere else to get help. Interesting. Our approaches to VPN have to change – it’s not like your bank requires one. Our approaches to support have to change – students and staff work 24×7, so why were we only supporting them 8-6? Adelaide now has a contract service outside of those hours to take the 100 important calls that would have been terrible had they not been fixed.

Mark thinks that IDM and access need to be fixed, it makes up 24% of their reported problems: password broken, I can’t get on and so on.

Security used to be on the device that the Uni owned. This has changed. Now it has to be data security, as you can’t guarantee that you own the device. Virtual desktops and virtual apps can offer data containerisation among their other benefits.

Let’s change the thinking from setting a perimeter to the person themselves. The boundaries are shifting and, let’s be honest, the inside of any network with 30,000 people is going to be swampy anyway.

Project management thinking is shifting from traditional to agile, which gets closer to the customer on shorter and smaller projects. But you have to change how you think about projects.

A lot of tools used to get built that worked with data but now people want to make this part of their decision infrastructure. Data quality is now very important.

The massive shift is from “provide and control” to “advise and enable”. (Sorry, auditors.) Another massive shift is from automation of a process that existed to support a business to help in designing the processes that will support the business. This is a driver back into policy space. (Sorry, central admin branch.) At the same time, Mark believes that they’re transitioning from a functional approach to a customer-centric focus. A common services layer will serve the student, L&T, research and admin groups but those common services may not be developed or even hosted inside the institution.

It’s not a surprise to anyone who’s been following what Mark has been doing, but he believes that the role is shifting from IT operations to University strategy.

Some customers are going to struggle. Some people will always need help. But what about those highly capable individuals who could help you? This is where innovation and co-creation can take place, with specific people across the University.

Mark wants Uni IT organisations to disrupt themselves. (The Go8 are rather conservative and are not prone to discussing disruption, let alone disrupting.)

Basically, if customers can do it, make themselves happy and get what they want working, why are you in their way? If they can do it themselves, then get out of the way except for those things where you add value and make the experience better.  We’re helping people who are desperate but we’re not putting as much effort into the innovators and more radical thinkers. Mark’s belief is that investing more effort into collaboration, co-creation and innovation is the way to go.

It looks risky but is it? What happens if you put technology out there? How do you get things happening?

Mark wants us to move beyond Service Level Agreements, which he describes as the bottom bar. No great athlete performs at the top level because of an SLA. This requires a move to meaningful metrics. (Very similar to student assessment, of course! Same problem!) Just because we measure something doesn’t make it meaningful!

We tended to hire skills to provide IT support. Mark believes that we should now be hiring attributes: leaders, drivers, innovators. The customer wants to get somewhere. How can we help them?

Lots to think about – thanks, Mark!


EduTech Australia 2015, Day 1, Session 1, Part 2, Higher Ed Leaders #edutechau

The next talk was a video conference presentation, “Designed to Engage”, from Dr Diane Oblinger, formerly of EDUCAUSE (USA). Diane was joining us by video on the first day of retirement – that’s keen!

Today, technology is not enough, it’s about engagement. Diane believes that the student experience can be a critical differentiator in this. In many institutions, the student will be the differentiator. She asked us to consider three different things:

  1. What would life be like without technology? How does this change our experiences and expectations?
  2. Does it have to be human-or-machine? We often construct a false dichotomy of online versus face-to-face rather than thinking about them as a continuum.
  3. Changes in demography are causing new consumption patterns.

Consider changes in the four key areas:

  • Learning
  • Pathways
  • Credentialing
  • Alternate Models

To speak to learning, Diane wants us to think about learning for now, rather than based on our own experiences. What will happen when classic college meets online?

Diane started from the premise that higher order learning comes from complex challenges – how can we offer this to students? Well, there are game-based, high experiential activities. They’re complex, interactive, integrative, information gathering driven, team focused and failure is part of the process. They also develop tenacity (with enough scaffolding, of course). We also get, almost for free, vast quantities of data to track how students performed their solving activities, which is far more than “right” or “wrong”. Does a complex world need more of these?

The second point for learning environments is that, sometimes, massive and intensive can go hand-in-hand. The Georgia Tech Online Master of Science in Computer Science, on Udacity , with assignments, TAs and social media engagements and problem-solving.  (I need to find out more about this. Paging the usual suspects.)

The second area discussed was pathways. Students lose time, track and credits when they start to make mistakes along the way and this can lead to them getting lost in the system. Cost is a huge issue in the US (and, yes, it’s a growing issue in Australia, hooray.)  Can you reduce cost without reducing learning? Students are benefiting from guided pathways to success. Georgia State and their predictive analytics were mentioned again here – leading students to more successful pathways to get better outcomes for everyone. Greatly increased retention, greatly reduced wasted tuition fees.

We now have a lot more data on what students are doing – the challenge for us is how we integrate this into better decision making. (Ethics, accuracy, privacy are all things that we have to consider.)

Learning needs to not be structured around seat time and credit hours. (I feel dirty even typing that.) Our students learn how to succeed in the environments that we give them. We don’t want to train them into mindless repetition. Once again, competency based learning, strongly formative, reflecting actual knowledge, is the way to go here.

(I really wish that we’d properly investigated the CBL first year. We might have done something visionary. Now we’ll just look derivative if we do it three years from now. Oh, well, time to start my own University – Nickapedia, anyone?)

Credentials raised their ugly head again – it’s one of the things that Unis have had in the bag. What is the new approach to credentials in the digital environment? Certificates and diplomas can be integrated into your on-line identity. (Again, security, privacy, ethics are all issues here but the idea is sound.) Example given was “Degreed”, a standalone credentialing site that can work to bridge recognised credentials from provide to employer.

Alternatives to degrees are being co-created by educators and employers. (I’m not 100% sure I agree with this. I think that some employers have great intentions but, very frequently, it turns into a requirement for highly specific training that might not be what we want to provide.)

Can we reinvent an alternative model that reinvents delivery systems, business models and support models? Can a curriculum be decentralised in a centralised University? What about models like Minerva? (Jeff mentioned this as well.)

(The slides got out of whack with the speaker for a while, apologies if I missed anything.)

(I should note that I get twitchy when people set up education for-profit. We’ve seen that this is a volatile market and we have the tension over where money goes. I have the luxury of working for an entity where its money goes to itself, somehow. There are no shareholders to deal with, beyond the 24,000,000 members of the population, who derive societal and economic benefit from our contribution.)

As noted on the next slide, working learners represent a sizeable opportunity for increased economic growth and mobility. More people in college is actually a good thing. (As an aside, it always astounds me when someone suggests that people are spending too much time in education. It’s like the insult “too clever by half”, you really have to think about what you’re advocating.)

For her closing thoughts, Diane thinks:

  1. The boundaries of the educational system must be re-conceptualised. We can’t ignore what’s going on around us.
  2. The integration of digital and physical experiences are creating new ways to engage. Digital is here and it’s not going away. (Unless we totally destroy ourselves, of course, but that’s a larger problem.)
  3. Can we design a better future for education.

Lots to think about and, despite some technical issues, a great talk.

 


EduTech Australia 2015, Day 1, Session 1, Higher Education Leaders @jselingo #edutechau

Emeritus Professor Steven Schwartz, AM, opened the Higher Ed leaders session, following a very punchy video on how digital is doing “zoom” and “rock and roll” things. (I’m a bit jaded about “tech wow” videos but this one was pretty good. It reinforced the fact that over 60% of all web browsing is carried out on mobile devices, which should be a nudge to all of us designing for the web.)

There will be roughly 5,000 participants in the totally monstrous Brisbane Convention Centre. There are many people here that I know but I’m beginning to doubt whether I’m going to see many of them unless they’re speaking – there’s a mass of educational humanity here, people!

The opening talk was “The Universities of tomorrow, the future of anytime and anywhere learning”, presented by Jeffrey Selingo. Jeff writes books, “College Unbound” among others, and is regular contributor to the Washington Post and the Chronicle. (I live for the day I can put “Education Visionary” on my slides with even a shred of this credibility. As a note, remarks in parentheses are probably my editorial comments.)

(I’ve linked to Jeff on Twitter. Please correct me on anything, Jeff!)

Jeff sought out to explore the future of higher learning, taking time out from editing the Chronicle. He wanted to tell the story of higher ed for the coming decade, for those parents and students heading towards it now, rather than being in it now. Jeff approached it as a report, rather than an academic paper, and is very open about the fact that he’s not conducting research. “In journalism, if you have three anecdotes, you have a trend.”

(I’m tempted to claim phenomenography but I know you’ll howl me down. And rightly so!)

Higher Ed is something that, now, you encounter once in our lives and then move on. But the growth in knowledge and ongoing explosion of new information doesn’t match that model. Our Higher Ed model is based on an older tradition and and older informational model.

(This is great news for me, I’m a strong advocate of an integrated and lifelong Higher Ed experience)

(Slides for this talk available at http://jeffselingo.com/conference

Be warned, you have to sign up for a newsletter to get the slides.)

Jeff then talked about his start, in one of the initial US college rankings, before we all ranked each other into the ground. The ‘prestige race’ as he refers to it. Every university around the world wanted to move up the ladder. (Except for the ones on the top, kicking at the rungs below, no doubt.)

“Prestige is to higher education as profit is to corporations.”

According to Caroline Hoxby, Higher Ed student flow has increased as students move around the world. Students who can move to different Universities, now tend to do so and they can exercise choices around the world. This leads to predictions like “the bottom 25% of Unis will go out of business or merge” (Clay Christensen) – Jeff disagrees with this although he thinks change is inevitable.

We have a model of new, technologically innovative and agile companies destroy the old leaders. Netflix ate Blockbuster. Amazon ate Borders. Apple ate… well, everybody… but let’s say Tower Records, shall we? Jeff noted that journalism’s upheaval has been phenomenal, despite the view of journalism as a ‘public trust’. People didn’t want to believe what was going to happen to their industry.

Jeff believes that students are going to drive the change. He believes that students are often labelled as “Traditional” (ex-school, 18-22, direct entry) and “non-Traditional” (adult learners, didn’t enter directly.) But what this doesn’t capture is the mindset or motivation of students to go to college. (MOOC motivation issues, anyone?)

What do students want to get out of their degree?

(Don’t ask difficult questions like that, Jeff! It is, of course, a great question and one we try to ask but I’m not sure we always listen.)

Why are you going? What do you want? What do you want your degree to look like? Jeff asked and got six ‘buckets’ of students in two groups, split across the trad/non-trad age groups.

Group 1 are the younger group and they break down into.

  • Young Academics (24%) – the trad high-performing students who have mastered the earlier education systems and usually have a privileged background
  • Coming of Age (11%) – Don’t quite know what they want from Uni but they were going to college because it was the place to go to become an adult. This is getting them ready to go to the next step, the work force.
  • Career Starters (18%) – Students who see the Uni as a means to the end, credentialing for the job that they want. Get through Uni as quickly as possible.

Group 2 are older:

  • Career Accelerators (21%) – Older students who are looking to get new credentials to advance themselves in their current field.
  • Industry Switchers – Credential changers to move to a new industry.
  • Adult Wanderers – needed a degree because that was what the market told them but they weren’t sure why

(Apologies for losing some of the stats, the room’s quite full and some people had to walk past me.)

But that’s what students are doing – what skills are required out there from the employers?

  • Written and Oral communication
  • Managing multiple priorities
  • Collaboration
  • Problem solving

People used to go to college for a broad knowledge base and then have that honed by an employer or graduate school to focus them into a discipline. Now, both of these are expected at the Undergrad level, which is fascinating given that we don’t have extra years to add to the degree. But we’re not preparing students better to enter college, nor do we have the space for experiential learning.

Expectations are greater than ever but are we delivering?

When do we need higher education? Well, it used to be “education” then “employment” then “retirement”. The new model, today, (from Georgetown, Tony Carnevale), we have “education”, then “learning and earning”, then “full-time work and on-the-job training”, “transition to retirement” and, finally, “full retirement”. Students are finally focusing on their career at around 30, after leaving the previous learning phases. This is, Jeff believes, where we are not playing an important role for students in their 20s, which is not helping them in their failure to launch.

Jeff was wondering how different life would be for the future, especially given how much longer we are going to be living. How does that Uni experience of “once in our lives, in one physical place” fit in, if people may switch jobs much more frequently over a longer life? The average person apparently switches jobs every four years – no wonder most of the software systems I use are so bad!

Je”s “College Unbound” future is student-driven, student-centred, and not a box that is entered at 18 and existed 4 years later, it’s a platform for life-long learning.

“The illiterate will be those who cannot learn, unlearn and relearn” – Alvin Toffler

Jeff doesn’t think that there will be one simple path to the future. Our single playing field competition of institutions has made us highly similar in the higher ed sector. How can we personalise pathways to the different groups of students that we saw above? Predictive analytics are important here – technology is vital. Good future education will be adaptive and experiential, combining the trad classroom with online systems. apprenticeships and, overall, removing the requirement to reside at or near your college.

Jeff talked about some new models, starting with the Swirl, the unbundled degree across different institutions, traditional snd not. Multiple universities, multiple experiences = degree.

Then there’s mixing course types, mixing face-to-face with hybrid and online to accelerate their speed of graduation. (There is a strong philosophical point on this that I hope to get back to later: why are we racing through University?)

Finally, competency-based learning allowed a learner to have class lengths from 2 weeks to 14 weeks, based on what she already knew. (I am a really serious advocate of this approach. I advocated to switch our entire first year for Engineering to a competency based approach but I’ll write more about that later on. And, no, we didn’t do it but at least we thought about it.)

In the mix are smaller chunks of information and just-in-time learning. Anyone who has used YouTube for a Photoshop tutorial has had a positive (well, as positive as it can be) experience with this. Why can’t we do this with any number of higher ed courses?

A note on the Stanford 2025 Design School exercise: the open loop education. Accepted to Stanford would give you access to 6 years of education that you would be able to use at any point in your life. Take two years, go out and work a bit, come back. Why isn’t the University at the centre of our lifelong involvement with learning?

The distance between producer and consumer is shrinking, whether it’s online stores or 3-D printing. Example given was MarginalRevolutionUniversity, a homegrown University, developed by a former George Mason academic.

As aways, the MOOC dropout rate was raised. Yes, only 10% complete, but Jeff’s interviews confirm what we already know, most of those students had no intention of completing. They didn’t think of the MOOC course as a course or as part of a degree, they were dipping in to get what they needed, when they needed it. Just like those YouTube Photoshop tutorials.

The difficult question is how certify this. And… here are badges again, part of certification of learning and the challenge is how we use them.

Jeff think that there are still benefits for residential experience, although assisted and augmented with technology:

  • Faculty mentoring
  • Undergraduate research (team work, open problems)
  • Be creative. Take Risks. Learn how to fail.
  • Cross-cultural experience.

Of course, not all of this is available to everyone. And what is the return on investment for this? LinkedIn finally has enough data that we can start to answer that question. (People will tell LinkedIn things that they won’t tell other people, apparently.) This may change the ranking game because rankings can now be conducted on outputs rather than inputs. Watch this space?

The world is changing. What does Jeff think? Ranking is going to change and we need to be able to prove our value. We have to move beyond isolated disciplines. Skill certification is going to get harder but the overall result should be better. University is for life, not just for three years. This will require us to build deep academic alliances that go beyond our traditional boxes.

Ok, prepping for the next talk!


What to support? Thoughts on funding for ideas. We must fund the forges of creativity as well as the engines of science (@JulianBurnside #ideasforaus)

Screen Shot 2015-05-03 at 3.56.11 pm

The barrister and #HumanRightsExtremist, Julian Burnside AO QC, was part of today’s Carnegie Conversations at the Opera House. While I’m not there, I was intrigued by a tweet he sent about other discussions going on today regarding the investment of our resources to do the maximum good. (I believe that this was the session following his, with Peter Singer and chaired by Ann Cherry.)

Mr Burnside’s Tweet was (for those who haven’t seen the image):

What to support? Effective Altruism is good, but what about funding the arts, ideas and other things which can’t be measured?

Some of the responses to this Tweet tried to directly measure the benefits of a cure for Malaria against funding the arts and, to me, this misses the point. I am a scientist, an artist, a husband, a cat steward, and many other things. As a scientist, I use the scientific method when I am undertaking my research into improving education for students and developing better solutions for use of technology. If you were to ask me which is better, putting funds into distributing a malarial cure or subsiding an opera, then we are so close to the endpoint of the activity that the net benefit can be measured. But if you were to ask me whether this means we could defund the arts to concentrate on biological science, I’d have to say no, because the creative development of solutions is not strictly linked to the methodical application of science.

As a computer scientist, I work in vast artificial universes where it is impossible to explore every option because we do not have enough universe. I depend upon insights and creativity to help me work out the solutions, which I can then test methodically. This is a known problem in all forms of large-scale optimisation – we have to settle for finding what we can, seeking the best, and we often have to step away to make sure that the peak we have ascended is not a foothill in the shadow of a greater mountain.

Measuring what goes into the production of a new idea is impossible. I can tell you that a number of my best solutions have come from weeks or months of thinking, combined with music, visits to art galleries, working with my hands, the pattern of water in the shower and the smell of fresh bread.

Once we have an idea then, yes, absolutely, let us fund centres and institutions that support and encourage the most rigorous and excellent mechanisms for turning ideas into reality. When we have a cure for malaria, we must fund it and distribute it, working on ways to reduce delays and cost mark-ups to those who need it most. But we work in spaces so big that walking the whole area is impossible. We depend upon leaps of intuition, creative exploration of solution spaces and, on occasion, flashes of madness to find the ideas that we can then develop

To think that we can focus only on the measurable outcomes is to totally miss the fact that we have no real idea where many of our best ideas come from and yet so many of us have stories of insight and clarity that stem from our interactions with a rich, developed culture of creativity. And that means funding the arts, the ideas and things that we cannot measure.

(Edited to make the hashtag at the top less likely to be misparsed.)


Think. Create. Code. Vis! (@edXOnline, @UniofAdelaide, @cserAdelaide, @code101x, #code101x)

I just posted about the massive growth in our new on-line introductory programming course but let’s look at the numbers so we can work out what’s going on and, maybe, what led to that level of success. (Spoilers: central support from EdX helped a huge amount.) So let’s get to the data!

I love visualised data so let’s look at the growth in enrolments over time – this is really simple graphical stuff as we’re spending time getting ready for the course at the moment! We’ve had great support from the EdX team through mail-outs and Twitter and you can see these in the ‘jumps’ in the data that occurred at the beginning, halfway through April and again at the end. Or can you?

Rapid growth in enrolment!

Rapid growth in enrolment! But it’s a little hard to see in this data.

Hmm, this is a large number, so it’s not all that easy to see the detail at the end. Let’s zoom in and change the layout of the data over to steps so we can things more easily. (It’s worth noting that I’m using the free R statistical package to do all of this. I can change one line in my R program and regenerate all of my graphs and check my analysis. When you can program, you can really save time on things like this by using tools like R.)

Screen Shot 2015-04-30 at 2.40.24 pm
Now you can see where that increase started and then the big jump around the time that e-mail advertising started, circled. That large spike at the end is around 1500 students, which means that we jumped 10% in a day.

When we started looking at this data, we wanted to get a feeling for how many students we might get. This is another common use of analysis – trying to work out what is going to happen based on what has already happened.

As a quick overview, we tried to predict the future based on three different assumptions:

  1. that the growth from day to day would be roughly the same, which is assuming linear growth.
  2. that the growth would increase more quickly, with the amount of increase doubling every day (this isn’t the same as the total number of students doubling every day).
  3. that the growth would increase even more quickly than that, although not as quickly as if the number of students were doubling every day.

If Assumption 1 was correct, then we would expect the graph to look like a straight line, rising diagonally. It’s not. (As it is, this model predicted that we would only get 11,780 students. We crossed that line about 2 weeks ago.

So we know that our model must take into account the faster growth, but those leaps in the data are changes that caused by things outside of our control – EdX sending out a mail message appears to cause a jump that’s roughly 800-1,600 students, and it persists for a couple of days.

Let’s look at what the models predicted. Assumption 2 predicted a final student number around 15,680. Uhh. No. Assumption 3 predicted a final student number around 17,000, with an upper bound of 17,730.

Hmm. Interesting. We’ve just hit 17,571 so it looks like all of our measures need to take into account the “EdX” boost. But, as estimates go, Assumption 3 gave us a workable ballpark and we’ll probably use it again for the next time that we do this.

Now let’s look at demographic data. We now we have 171-172 countries (it varies a little) but how are we going for participation across gender, age and degree status? Giving this information to EdX is totally voluntary but, as long as we take that into account, we make some interesting discoveries.

Age demographic data from EdX

Age demographic data from EdX

Our median student age is 25, with roughly 40% under 25 and roughly 40% from 26 to 40. That means roughly 20% are 41 or over. (It’s not surprising that the graph sits to one side like that. If the left tail was the same size as the right tail, we’d be dealing with people who were -50.)

The gender data is a bit harder to display because we have four categories: male, female, other and not saying. In terms of female representation, we have 34% of students who have defined their gender as female. If we look at the declared male numbers, we see that 58% of students have declared themselves to be male. Taking into account all categories, this means that our female participant percentage could be as high as 40% but is at least 34%. That’s much higher than usual participation rates in face-to-face Computer Science and is really good news in terms of getting programming knowledge out there.

We’re currently analysing our growth by all of these groupings to work out which approach is the best for which group. Do people prefer Twitter, mail-out, community linkage or what when it comes to getting them into the course.

Anyway, lots more to think about and many more posts to come. But we’re on and going. Come and join us!


Think. Create. Code. Wow! (@edXOnline, @UniofAdelaide, @cserAdelaide, @code101x, #code101x)

Screenshot of our EdX page.

Screenshot of our EdX page. Shiny!

Things are really exciting here because, after the success of our F-6 on-line course to support teachers for digital technologies, the Computer Science Education Research group are launching their first massive open on-line course (MOOC) through AdelaideX, the partnership between the University of Adelaide and EdX. (We’re also about to launch our new 7-8 course for teachers – watch this space!)

Our EdX course is called “Think. Create. Code.” and it’s open right now for Week 0, although the first week of real content doesn’t go live until the 30th. If you’re not already connected with us, you can also follow us on Facebook (code101x) or Twitter (@code101x), or search for the hashtag #code101x. (Yes, we like to be consistent.)

I am slightly stunned to report that, less than 24 hours before the first content starts to roll out, that we have 17,531 students enrolled, across 172 countries. Not only that, but when we look at gender breakdown, we have somewhere between 34-42% women (not everyone chooses to declare a gender). For an area that struggles with female participation, this is great news.

I’ll save the visualisation data for another post, so let’s quickly talk about the MOOC itself. We’re taking a 6 week approach, where students focus on developing artwork and animation using the Processing language, but it requires no prior knowledge and runs inside a browser. The interface that has been developed by the local Adelaide team (thank you for all of your hard work!) is outstanding and it’s really easy to make things happen.

I love this! One of the biggest obstacles to coding is having to wait until you see what happens and this can lead to frustration and bad habits. In Processing you can have a circle on the screen in a matter of seconds and you can start playing with colour in the next second. There’s a lot going on behind the screen to make it this easy but the student doesn’t need to know it and can get down to learning. Excellent!

I went to a great talk at CSEDU last year, presented by Hugh Davis from Southampton, where Hugh raised some great issues about how MOOCs compared to traditional approaches. I’m pleased to say that our demography is far more widespread than what was reported there. Although the US dominates, we have large representations from India, Asia, Europe and South America, with a lot of interest from Africa. We do have a lot of students with prior degrees but we also have a lot of students who are at school or who aren’t at University yet. It looks like the demography of our programming course is much closer to the democratic promise of free on-line education but we’ll have to see how that all translates into participation and future study.

While this is an amazing start, the whole team is thinking of this as part of a project that will be going on for years, if not decades.

When it came to our teaching approach, we spent a lot of time talking (and learning from other people and our previous attempts) about the pedagogy of this course: what was our methodology going to be, how would we implement this and how would we make it the best fit for this approach? Hugh raised questions about the requirement for pedagogical innovation and we think we’ve addressed this here through careful customisation and construction (we are working within a well-defined platform so that has a great deal of influence and assistance).

We’ve already got support roles allocated to staff and students will see us on the course, in the forums, and helping out. One of the reasons that we tried to look into the future for student numbers was to work out how we would support students at this scale!

One of our most important things to remember is that completion may not mean anything in the on-line format. Someone comes on and gets an answer to the most pressing question that is holding them back from coding, but in the first week? That’s great. That’s success! How we measure that, and turn that into traditional numbers that match what we do in face-to-face, is going to be something we deal with as we get more information.

The whole team is raring to go and the launch point is so close. We’re looking forward to working with thousands of students, all over the world, for the next six weeks.

Musing on Industrial Time

Now Print, Black, Linocut, (C) Nick Falkner, 2013

I caught up with a good friend recently and we were discussing the nature of time. She had stepped back from her job and was now spending a lot of her time with her new-born son. I have gone to working three days a week, hence have also stepped back from the five-day grind.  It was interesting to talk about how this change to our routines had changed the way that we thought of and used time. She used a term that I wanted to discuss here, which was industrial timeto describe the clock-watching time of the full-time worker. This is part of the larger area of time discipline, how our society reacts to and uses time, and is really quite interesting. Both of us had stopped worrying about the flow of time in measurable hours on certain days and we just did things until we ran out of day. This is a very different activity from the usual “do X now, do Y in 15 minutes time” that often consumes us. In my case, it took me about three months of considered thought and re-training to break the time discipline habits of thirty years. In her case, she has a small child to help her to refocus her time sense on the now.

Modern time-sense is so pervasive that we often don’t think about some of the underpinnings of our society. It is easy to understand why we have years and, although they don’t line up properly, months given that these can be matched to astronomical phenomena that have an effect on our world (seasons and tides, length of day and moonlight, to list a few). Days are simple because that’s one light/dark cycle. But why there are 52 weeks in a year? Why are there 7 days in a week? Why did the 5-day week emerge as a contiguous block of 5 days? What is so special about working 9am to 5pm?

A lot of modern time descends from the struggle of radicals and unionists to protect workers from the excesses of labour, to stop people being worked to death, and the notion of the 8 hour day is an understandable division of a 24 hour day into three even chunks for work, rest and leisure. (Goodness, I sound like I’m trying to sell you chocolate!)

If we start to look, it turns out that the 7 day week is there because it’s there, based on religion and tradition. Interestingly enough, there have been experiments with other week lengths but it appears hard to shift people who are used to a certain routine and, tellingly, making people wait longer for days off appears to be detrimental to adoption.

If we look at seasons and agriculture, then there is a time to sow, to grow, to harvest and to clear, much as there is a time for livestock to breed and to be raised for purpose. If we look to the changing time of sunrise and sunset, there is a time at which natural light is available and when it is not. But, from a time discipline perspective, these time systems are not enough to be able to build a large-scale, industrial and synchronised society upon – we must replace a distributed, loose and collective notion of what time is with one that is centralised, authoritarian and singular. While religious ceremonies linked to seasonal and astronomical events did provide time-keeping on a large scale prior to the industrial revolution, the requirement for precise time, of an accuracy to hours and minutes, was not possible and, generally, not required beyond those cues given from nature such as dawn, noon, dusk and so on.

After the industrial revolution, industries and work was further developed that was heavily separated from a natural linkage – there are no seasons for a coal mine or a steam engine – and the development of the clock and reinforcement of the calendar of work allowed both the measurement of working hours (for payment) and the determination of deadlines, given that natural forces did not have to be considered to the same degree. Steam engines are completed, they have no need to ripen.

With the notion of fixed and named hours, we can very easily determine if someone is late when we have enough tools for measuring the flow of time. But this is, very much, the notion of the time that we use in order to determine when a task must be completed, rather than taking an approach that accepts that the task will be completed at some point within a more general span of time.

We still have confusion where our understanding of “real measures” such as days, interact with time discipline. Is midnight on the 3rd of April the second after the last moment of April the 2nd or the second before the first moment of April the 4th? Is midnight 12:00pm or 12:00am? (There are well-defined answers to this but the nature of the intersection is such that definitions have to be made.)

But let’s look at teaching for a moment. One of the great criticisms of educational assessment is that we confuse timeliness, and in this case we specifically mean an adherence to meeting time discipline deadlines, with achievement. Completing the work a crucial hour after it is due can lead to that work potentially not being marked at all, or being rejected. But we do usually have over-riding reasons for doing this but, sadly, these reasons are as artificial as the deadlines we impose. Why is an Engineering Degree a four-year degree? If we changed it to six would we get better engineers? If we switched to competency based training, modular learning and life-long learning, would we get more people who were qualified or experienced with engineering? Would we get less? What would happen if we switched to a 3/1/2/1 working week? Would things be better or worse? It’s hard to evaluate because the week, and the contiguous working week, are so much a part of our world that I imagine that today is the first day that some of you have thought about it.

Back to education and, right now, we count time for our students because we have to work out bills and close off accounts at end of financial year, which means we have to meet marking and award deadlines, then we have to project our budget, which is yearly, and fit that into accredited degree structures, which have year guidelines…

But I cannot give you a sound, scientific justification for any of what I just wrote. We do all of that because we are caught up in industrial time first and we convince ourselves that building things into that makes sense. Students do have ebb and flow. Students are happier on certain days than others. Transition issues on entry to University are another indicator that students develop and mature at different rates – why are we still applying industrial time from top to bottom when everything we see here says that it’s going to cause issues?

Oh, yes, the “real world” uses it. Except that regular studies of industrial practice show that 40 hour weeks, regular days off, working from home and so on are more productive than the burn-out, everything-late, rush that we consider to be the signs of drive. (If Henry Ford thinks that making people work more than 40 hours a week is bad for business, he’s worth listening to.) And that’s before we factor in the development of machines that will replace vast numbers of human jobs in the next 20 years.

I have a different approach. Why aren’t we looking at students more like we regard our grape vines? We plan, we nurture, we develop, we test, we slowly build them to the point where they can produce great things and then we sustain them for a fruitful and long life. When you plant grape vines, you expect a first reasonable crop level in three years, and commercial levels at five. Tellingly, the investment pattern for grapes is that it takes you 10 years to break even and then you start making money back. I can’t tell you how some of my students will turn out until 15-25 years down the track and it’s insanity to think you can base retrospective funding on that timeframe.

You can’t make your grapes better by telling them to be fruitful in two years. Some vines take longer than others. You can’t even tell them when to fruit (although can trick them a little). Yet, somehow, we’ve managed to work around this to produce a local wine industry worth around $5 billion dollars. We can work with variation and seasonal issues.

One of the reasons I’m so keen on MOOCs is that these can fit in with the routines of people who can’t dedicate themselves to full-time study at the moment. By placing well-presented, pedagogically-sound materials on-line, we break through the tyranny of the 9-5, 5 day work week and let people study when they are ready to, where they are ready to, for as long as they’re ready to. Like to watch lectures at 1am, hanging upside down? Go for it – as long as you’re learning and not just running the video in the background while you do crunches, of course!

Once you start to question why we have so many days in a week, you quickly start to wonder why we get so caught up on something so artificial. The simple answer is that, much like money, we have it because we have it. Perhaps it’s time to look at our educational system to see if we can do something that would be better suited to developing really good knowledge in our students, instead of making them adept at sliding work under our noses a second before it’s due. We are developing systems and technologies that can allow us to step outside of these structures and this is, I believe, going to be better for everyone in the process.

Conformity isn’t knowledge, and conformity to time just because we’ve always done that is something we should really stop and have a look at.


I want you to be sad. I want you to be angry. I want you to understand.

Nick Falkner is an Australian academic with a pretty interesting career path. He is also a culture sponge and, given that he’s (very happily) never going to be famous enough for a magazine style interview, he interviews himself on one of the more confronting images to come across the wires recently. For clarity, he’s the Interviewer (I) when he’s asking the questions.

The photo of Indian parents helping their children to "cheat" (Original: STRDEL/AFP/GETTY IMAGES)

The photo of Indian parents helping their children to “cheat” (Original: STRDEL/AFP/GETTY IMAGES)

Interviewer: As you said, “I want you to be sad. I want you to be angry. I want you to understand.” I’ve looked at the picture and I can see a lot of people who are being associated with a mass cheating scandal in the Indian state of Bihar. This appears to be a systematic problem, especially as even more cheating has been exposed in the testing for the police force! I think most people would agree that it’s a certainly a sad state of affairs and there are a lot of people I’ve heard speaking who are angry about this level of cheating – does this mean I understand? Basically, cheating is wrong?

Nick: No. What’s saddening me is that most of the reaction I’ve seen to this picture is lacking context, lacking compassion and, worse, perpetrating some of the worst victim blaming I’ve ever seen. I’m angry because people still don’t get that the system in place is Bihar, and wherever else we put systems like this, is going to lead to behaviour like this out of love and a desire for children to have opportunity, rather than some grand criminal scheme of petty advancement.

Interviewer: Well, ok, that’s a pretty strong set of statements. Does this mean that you think cheating is ok?

Nick: (laughs) Well, we’ve got the most usual response out of the way. No, I don’t support “cheating” in any educational activity because it means that the student is bypassing the learning design and, if we’ve done our job, this will be to their detriment. However, I also strongly believe that some approaches to large-scale education naturally lead to a range of behaviours where external factors can affect the perceived educational benefit to the student. In other words, I don’t want students to cheat but I know that we sometimes set things up so that cheating becomes a rational response and, in some cases, the only difference between a legitimate advantage and “cheating” is determined by privilege, access to funds and precedent.

Interviewer: Those are big claims. And you know what that means…

Nick: You want evidence! Ok. Let’s start with some context. Bihar is the third-largest state in India by population, with over 100 million people, the highest density of population in India, the largest number of people under 25 (nearly 60%), a heavily rural population (~85%) and a literacy rate around 64%. Bihar is growing very quickly but has put major work into its educational systems. From 2001 to 2011, literacy jumped from 48 to 64% – 20 of those percentage points are in increasing literacy in women alone.

If we took India out of the measurement, Bihar is in the top 11 countries in the world by population. And it’s accelerating in growth. At the same time, Bihar has lagged behind other Indian states in socio-economic development (for a range of reasons – it’s very … complicated). Historically, Bihar has been a seat of learning but recent actions, including losing an engineering college in 2000 due to boundary re-alignment, means that they are rebuilding themselves right now. At the same time, Bihar has a relatively low level of industrialisation by Indian standards although it’s redefining itself away from agriculture to services and industry at the moment, with some good economic growth. There are some really interesting projects on the horizon – the Indian Media Hub, IT centres and so on – which may bring a lot more money into the region.

Interviewer: Ok, Bihar is big, relatively poor … and?

Nick: And that’s the point. Bihar is full of people, not all of whom are literate, and many of whom still live in Indian agricultural conditions. The future is brightening for Bihar but if you want to be able to take advantage of that, then you’re going to have to be able to get into the educational system in the first place. That exam that the parents are “helping” their children with is one that is going to have an almost incomprehensibly large impact on their future…

Interviewer: Their future employment?

Nick:  Not just that! This will have an impact on whether they live in a house with 24 hour power. On whether they will have an inside toilet. On whether they will be able to afford good medicine when they or their family get sick. On whether they will be able to support their parents when they get old. On how good the water they drink is. As well, yes, it will help them to get into a University system where, unfortunately, existing corruption means that money can smooth a path where actual ability has led to a rockier road. The article I’ve just linked to mentions pro-cheating rallies in Uttar Pradesh in the early 90s but we’ve seen similar arguments coming from areas where rote learning, corruption and mass learning systems are thrown together and the students become grist to a very hard stone mill.  And, by similar arguments, I mean pro-cheating riots in China in 2013. Student assessment on the massive scale. Rote learning. “Perfect answers” corresponding to demonstrating knowledge. Bribery and corruption in some areas. Angry parents because they know that their children are being disadvantaged while everyone else is cheating. Same problem. Same response.

Interviewer: Well, it’s pretty sad that those countries…

Nick: I’m going to stop you there. Every time that we’ve forced students to resort to rote learning and “perfect answer” memorisation to achieve good outcomes, we’ve constructed an environment where carrying in notes, or having someone read you answers over a wireless link, suddenly becomes a way to successfully reach that outcome. The fact that this is widely used in the two countries that have close to 50% of the world’s population is a reflection of the problem of education at scale. Are you volunteering to sit down and read the 50 million free-form student essays that are produced every year in China under a fairer system? The US approach to standardised testing isn’t any more flexible. Here’s a great article on what’s wrong with the US approach because it identifies that these tests are good for measuring conformity to the test and its protocol, not the quality of any education received or the student’s actual abilities. But before we get too carried away about which countries cheat most, here are some American high school students sharing answers on Twitter.

Every time someone talks about the origin of a student, rather than the system that a student was trained under, we start to drift towards a racist mode of thinking that doesn’t help. Similar large-scale, unimaginative, conform-or-perish tests that you have to specifically study for across India, China and the US. What do we see? No real measurement of achievement or aptitude. Cheating. But let’s go back to India because the scale of the number of people involved really makes the high stakes nature of these exams even more obvious. Blow your SATs or your GREs and you can still do OK, if possibly not really well, in the US. In India… let’s have a look.

State Bank of India advertised some entry-level vacancies back in 2013. They wanted 1,500 people. 17 million applied. That’s roughly the adult population of Australia applying for some menial work at the bank. You’ve got people who are desperate to work, desperate to do something with their lives. We often think of cheats as being lazy or deceitful when it’s quite possible to construct a society so that cheating is part of a wider spectrum of behaviour that helps you achieve your goals. Performing well in exams in India and China is a matter of survival when you’re talking about those kinds of odds, not whether you get a great or an ok job.

Interviewer: You’d use a similar approach to discuss the cheating on the police exam?

Nick: Yes. It’s still something that shouldn’t be happening but the police force is a career and, rather sadly, can also be a lucrative source of alternative income in some countries. It makes sense that this is also something that people consider to be very, very high stakes. I’d put money on similar things happening in countries where achieving driving licences are a high stakes activity. (Oh, good, I just won money.)

Interviewer: So why do you want us to be sad?

Nick: I don’t actually want people to be sad, I’d much prefer it if we didn’t need to have this discussion. But, in a nutshell, every parent in that picture is actually demonstrating their love and support for their children and family. That’s what the human tragedy is here. These Biharis probably don’t have the connections or money to bypass the usual constraints so the best hope that their kids have is for their parents to risk their lives climbing walls to slip them notes.

I mean, everyone loves their kids. And, really, even those of us without children would be stupid not to realise that all children are our children in many ways, because they are the future. I know a lot of parents who saw this picture and they didn’t judge the people on the walls because they could see themselves there once they thought about it.

But it’s tragic. When the best thing you can do for your child is to help them cheat on an exam that controls their future? How sad is that?

Interviewer: Do you need us to be angry? Reading back, it sounds like you have enough anger for all of us.

Nick: I’m angry because we keep putting these systems in place despite knowing that they’re rubbish. Rousseau knew it hundreds of years ago. Dewey knew it in the 1930s. We keep pretending that exams like this sort people on merit when all of our data tells us that the best indicator of performance is the socioeconomic status of the parents, rather than which school they go to. But, of course, choosing a school is a kind of “legal” cheating anyway.

Interviewer: Ok, now there’s a controversial claim.

Nick: Not really. Studies show us that students at private schools tend to get higher University entry marks, which is the gateway to getting into courses and also means that they’ve completed their studies. Of course, the public school students who do get in go on to get higher GPAs… (This article contains the data.)

Interviewer: So it all evens out?

Nick: (laughs) No, but I have heard people say that. Basically, sending your kids to a “better” school, one of the private schools or one of the high-performing publics, especially those that offer International Baccalaureate, is not going to hurt your child’s chances of getting a good Tertiary entry mark. But, of course, the amount of money required to go to a private school is not… small… and the districting of public schools means that you have to be in the catchment to get one of these more desirable schools. And, strangely enough, once you factor in the socio-economic factors and outlook for a school district, it’s amazing how often that the high-performing schools map into higher SEF areas. Not all of them and there are some magnificent efforts in innovative and aggressive intervention in South Australia alone but even these schools have limited spaces and depend upon the primary feeder schools. Which school you go to matters. It shouldn’t. But it does.

So, you could bribe someone to make the exam easier or you could pay up to AUD $24,160 in school fees every year to put your child into a better environment. You could go to your local public school or, if you can manage the difficulty and cost of upheaval, you could relate to a new suburb to get into a “better” public school. Is that fair to the people that your child is competing against to get into limited places at University if they can’t afford that much or can’t move? That $24,000 figure is from this year’s fees for one of South Australia’s most highly respected private schools. That figure is 10 times the nominal median Indian income and roughly the same as an experienced University graduate would make in Bihar each year. In Australia, the 2013 median household income was about twice that figure, before tax. So you can probably estimate how many Australian families could afford to put one, or more, children through that kind of schooling for 5-12 years and it’s not a big number.

The Biharis in the picture don’t have a better option. They don’t have the money to bribe or the ability to move. Do you know how I know? Because they are hanging precariously from a wall trying to help their children copy out a piece of information in perfect form in order to get an arbitrary score that could add 20 years to their lifespan and save their own children from dying of cholera or being poisoned by contaminated water.

Some countries, incredibly successful education stories like Finland (seriously, just Google “Finland Educational System” and prepare to have your mind blown), take the approach that every school should be excellent, every student is valuable, every teacher is a precious resource and worthy of respect and investment and, for me, these approaches are the only way to actually produce a fair system. Excellence in education that is only available to the few makes everyone corrupt, to a greater or lesser degree, whether they realise it or not. So I’m angry because we know exactly what happens with high stakes exams like this and I want everyone to be angry because we are making ourselves do some really awful things to ourselves by constantly bending to conform to systems like this. But I want people to be angry because the parents in the picture have a choice of “doing the right thing” and watching their children suffer, or “doing the wrong thing” and getting pilloried by a large and judgemental privileged group on the Internet. You love your kids. They love their kids. We should all be angry that these people are having to scramble for crumbs at such incredibly high stakes.

But demanding that the Indian government do something is hypocritical while we use similar systems and we have the ability to let money and mobility influence the outcome for students at the expense of other students. Go and ask Finland what they do, because they’re happy to tell you how they fixed things but people don’t seem to want to actually do most of the things that they have done.

Interviewer:  We’ve been talking for a while so we had better wrap up. What do you want people to understand?

Nick: What I always want people to understand – I want them to understand “why“. I want them to be able to think about and discuss why these images from a collapsing educational system is so sad. I want them to understand why our system is really no better. I want them to think about why struggling students do careless, thoughtless and, by our standards, unethical things when they see all the ways that other people are sliding by in the system or we don’t go to the trouble to construct assessment that actually rewards creative and innovative approaches.

I want people to understand that educational systems can be hard to get right but it is both possible and essential. It takes investment, it takes innovation, it takes support, it takes recognition and it takes respect. Why aren’t we doing this? Delaying investment will only make the problem harder!

Really, I want people to understand that we would have to do a very large amount of house cleaning before we could have the audacity to criticise the people in that photo and, even then, it would be an action lacking in decency and empathy.

We have never seen enough of a level playing field to make a meritocratic argument work because of ingrained privilege and disparity in opportunity.

Interviewer: So, basically, everything most people think about how education and exams work is wrong? There are examples of a fairer system but most of us never see it?

Nick: Pretty much. But I have hope. I don’t want people to stay sad or angry, I want those to ignite the next stages of action. Understanding, passion and action can change the world.

Interviewer: And that’s all we have time for. Thank you, Nick Falkner!


Is this a dress thing? #thedress

For those who missed it, the Internet recently went crazy over llamas and a dress. (If this is the only thing that survives our civilisation, boy, is that sentence going to confuse future anthropologists.) Llamas are cool (there ain’t no karma drama with a llama) so I’m going to talk about the dress. This dress (with handy RGB codes thrown in, from a Wired article I’m about to link to):

A picture of a dress taken in a way that confounds human colour sense.

Not even going to try to describe the colour.

When I first saw it, and I saw it early on, the poster was asking what colour it was because she’d taken a picture in the store of a blue and black dress and, yet, in the picture she took, it sometimes looked white and gold and it sometimes looked blue and black. The dress itself is not what I’m discussing here today.

Let’s get something out of the way. Here’s the Wired article to explain why two different humans can see this dress as two different colours and be right. Okay? The fact is that the dress that the picture is of is a blue and black dress (which is currently selling like hot cakes, by the way) but the picture itself is, accidentally, a picture that can be interpreted in different ways because of how our visual perception system works.

This isn’t a hoax. There aren’t two images (or more). This isn’t some elaborate Alternative Reality Game prank.

But the reaction to the dress itself was staggering. In between other things, I plunged into a variety of different social fora to observe the reaction. (Other people also noticed this and have written great articles, including this one in The Atlantic. Thanks for the link, Marc!) The reactions included:

  1. Genuine bewilderment on the part of people who had already seen both on the same device at nearly adjacent times and were wondering if they were going mad.
  2. Fierce tribalism from the “white and gold” and “black and blue” camps, within families, across social groups as people were convinced that the other people were wrong.
  3. People who were sure that it was some sort of elaborate hoax with two images. (No doubt, Big Dress was trying to cover something up.)
  4. Bordering-on-smug explanations from people who believed that seeing it a certain way indicated that they had superior “something or other”, where you can put day vision/night vision/visual acuity/colour sense/dressmaking skill/pixel awareness/photoshop knowledge.
  5. People who thought it was interesting and wondered what was happening.
  6. Attention policing from people who wanted all of social media to stop talking about the dress because we should be talking about (insert one or more) llamas, Leonard Nimoy (RIP, LLAP, \\//) or the disturbingly short lifespan of Russian politicians.

The issue to take away, and the reason I’ve put this on my education blog, is that we have just had an incredibly important lesson in human behavioural patterns. The (angry) team formation. The presumption that someone is trying to make us feel stupid, playing a prank on us. The inability to recognise that the human perceptual system is, before we put any actual cognitive biases in place, incredibly and profoundly affected by the processing shortcuts our perpetual systems take to give us a view of the world.

I want to add a new question to all of our on-line discussion: is this a dress thing?

There are matters that are not the province of simple perceptual confusion. Human rights, equality, murder, are only three things that do not fall into the realm of “I don’t quite see what you see”. Some things become true if we hold the belief – if you believe that students from background X won’t do well then, weirdly enough, then they don’t do well. But there are areas in education when people can see the same things but interpret them in different ways because of contextual differences. Education researchers are well aware that a great deal of what we see and remember about school is often not how we learned but how we were taught. Someone who claims that traditional one-to-many lecturing, as the only approach, worked for them, when prodded, will often talk about the hours spent in the library or with study groups to develop their understanding.

When you work in education research, you get used to people effectively calling you a liar to your face because a great deal of our research says that what we have been doing is actually not a very good way to proceed. But when we talk about improving things, we are not saying that current practitioners suck, we are saying that we believe that we have evidence and practice to help everyone to get better in creating and being part of learning environments. However, many people feel threatened by the promise of better, because it means that they have to accept that their current practice is, therefore, capable of improvement and this is not a great climate in which to think, even to yourself, “maybe I should have been doing better”. Fear. Frustration. Concern over the future. Worry about being in a job. Constant threats to education. It’s no wonder that the two sides who could be helping each other, educational researchers and educational practitioners, can look at the same situation and take away both a promise of a better future and a threat to their livelihood. This is, most profoundly, a dress thing in the majority of cases. In this case, the perceptual system of the researchers has been influenced by research on effective practice, collaboration, cognitive biases and the operation of memory and cognitive systems. Experiment after experiment, with mountains of very cautious, patient and serious analysis to see what can and can’t be learnt from what has been done. This shows the world in a different colour palette and I will go out on a limb and say that there are additional colours in their palette, not just different shades of existing elements. The perceptual system of other people is shaped by their environment and how they have perceived their workplace, students, student behaviour and the personalisation and cognitive aspects that go with this. But the human mind takes shortcuts. Makes assumptions. Has biasses. Fills in gaps to match the existing model and ignores other data. We know about this because research has been done on all of this, too.

You look at the same thing and the way your mind works shapes how you perceive it. Someone else sees it differently, You can’t understand each other. It’s worth asking, before we deploy crushing retorts in electronic media, “is this a dress thing?”

The problem we have is exactly as we saw from the dress: how we address the situation where both sides are convinced that they are right and, from a perceptual and contextual standpoint, they are. We are now in the “post Dress” phase where people are saying things like “Oh God, that dress thing. I never got the big deal” whether they got it or not (because the fad is over and disowning an old fad is as faddish as a fad) and, more reflectively, “Why did people get so angry about this?”

At no point was arguing about the dress colour going to change what people saw until a certain element in their perceptual system changed what it was doing and then, often to their surprise and horror, they saw the other dress! (It’s a bit H.P. Lovecraft, really.) So we then had to work out how we could see the same thing and both be right, then talk about what the colour of the dress that was represented by that image was. I guarantee that there are people out in the world still who are convinced that there is a secret white and gold dress out there and that they were shown a picture of that. Once you accept the existence of these people, you start to realise why so many Internet arguments end up descending into the ALL CAPS EXCHANGE OF BALLISTIC SENTENCES as not accepting that what we personally perceive as being the truth could not be universally perceived is one of the biggest causes of argument. And we’ve all done it. Me, included. But I try to stop myself before I do it too often, or at all.

We have just had a small and bloodless war across the Internet. Two teams have seized the same flag and had a fierce conflict based on the fact that the other team just doesn’t get how wrong they are. We don’t want people to be bewildered about which way to go. We don’t want to stay at loggerheads and avoid discussion. We don’t want to baffle people into thinking that they’re being fooled or be condescending.

What we want is for people to recognise when they might be looking at what is, mostly, a perceptual problem and then go “Oh” and see if they can reestablish context. It won’t always work. Some people choose to argue in bad faith. Some people just have a bee in their bonnet about some things.

“Is this a dress thing?”

In amongst the llamas and the Vulcans and the assassination of Russian politicians, something that was probably almost as important happened. We all learned that we can be both wrong and right in our perception but it is the way that we handle the situation that truly determines whether we’re handling the situation in the wrong or right way. I’ve decided to take a two week break from Facebook to let all of the latent anger that this stirred up die down, because I think we’re going to see this venting for some time.

Maybe you disagree with what I’ve written. That’s fine but, first, ask yourself “Is this a dress thing?”

Live long and prosper.


That’s not the smell of success, your brain is on fire.

Would you mind putting out the hippocampus when you have a chance?

I’ve written before about the issues of prolonged human workload leading to ethical problems and the fact that working more than 40 hours a week on a regular basis is downright unproductive because you get less efficient and error-prone. This is not some 1968 French student revolutionary musing on what benefits the soul of a true human, this is industrial research by Henry Ford and the U.S. Army, neither of whom cold be classified as Foucault-worshipping Situationist yurt-dwelling flower children, that shows that there are limits to how long you can work in a sustained weekly pattern and get useful things done, while maintaining your awareness of the world around you.

The myth won’t die, sadly, because physical presence and hours attending work are very easy to measure, while productive outputs and their origins in a useful process on a personal or group basis are much harder to measure. A cynic might note that the people who are around when there is credit to take may end up being the people who (reluctantly, of course) take the credit. But we know that it’s rubbish. And the people who’ve confirmed this are both philosophers and the commercial sector. One day, perhaps.

But anyone who has studied cognitive load issues, the way that the human thinking processes perform as they work and are stressed, will be aware that we have a finite amount of working memory. We can really only track so many things at one time and when we exceed that, we get issues like the helmet fire that I refer to in the first linked piece, where you can’t perform any task efficiently and you lose track of where you are.

So what about multi-tasking?

Ready for this?

We don’t.

There’s a ton of research on this but I’m going to link you to a recent article by Daniel Levitin in the Guardian Q&A. The article covers the fact that what we are really doing is switching quickly from one task to another, dumping one set of information from working memory and loading in another, which of course means that working on two things at once is less efficient than doing two things one after the other.

But it’s more poisonous than that. The sensation of multi-tasking is actually quite rewarding as we get a regular burst of the “oooh, shiny” rewards our brain gives us for finding something new and we enter a heightened state of task readiness (fight or flight) that also can make us feel, for want of a better word, more alive. But we’re burning up the brain’s fuel at a fearsome rate to be less efficient so we’re going to tire more quickly.

Get the idea? Multi-tasking is horribly inefficient task switching that feels good but makes us tired faster and does things less well. But when we achieve tiny tasks in this death spiral of activity, like replying to an e-mail, we get a burst of reward hormones. So if your multi-tasking includes something like checking e-mails when they come in, you’re going to get more and more distracted by that, to the detriment of every other task. But you’re going to keep doing them because multi-tasking.

I regularly get told, by parents, that their children are able to multi-task really well. They can do X, watch TV, do Y and it’s amazing. Well, your children are my students and everything I’ve seen confirms what the research tells me – no, they can’t but they can give a convincing impression when asked. When you dig into what gets produced, it’s a different story. If someone sits down and does the work as a single task, it will take them a shorter time and they will do a better job than if they juggle five things. The five things will take more than five times as long (up to 10, which really blows out time estimation) and will not be done as well, nor will the students learn about the work in the right way. (You can actually sabotage long term storage by multi-tasking in the wrong way.) The most successful study groups around the Uni are small, focused groups that stay on one task until it’s done and then move on. The ones with music and no focus will be sitting there for hours after the others are gone. Fun? Yes. Efficient? No. And most of my students need to be at least reasonably efficient to get everything done. Have some fun but try to get all the work done too – it’s educational, I hear. 🙂

It’s really not a surprise that we haven’t changed humanity in one or two generations. Our brains are just not built in a way that can (yet) provide assistance with the quite large amount of work required to perform multi-tasking.

We can handle multiple tasks, no doubt at all, but we’ve just got to make sure, for our own well-being and overall ability to complete the task, that we don’t fall into the attractive, but deceptive, trap that we are some sort of parallel supercomputer.
