ITiCSE 2014, Session 3C: Gender and Diversity, #ITiCSE2014 #ITiCSE @patitsel

This sessions was dedicated to the very important issues of gender and diversity. The opening talk in this session was “A Historical Examination of the Social Factors Affecting Female Participation in Computing”, presented by Elizabeth Patitsas (@patitsel). This paper was a literature review of the history of the social factors affecting the old professional association of the word “computer” with female arithmeticians to today’s very male computing culture. The review spanned 73 papers, 5 books, 2 PhD theses and a Computing Educators Oral History project. The mix of sources was pretty diverse. The two big caveats were that it only looked at North America (which means that the sources tend to focus on Research Intensive universities and white people) and that this is a big picture talk, looking at social forces rather than individual experiences. This means that, of course, individuals may have had different experiences.

The story begins in the 19th Century, when computer was a job and this was someone who did computations, for scientists, labs, or for government. Even after first wave feminism, female education wasn’t universally available and the women in education tended to be women of privilege. After the end of the 19th century, women started to enter traditional universities to attempt to study PhDs (although often receiving a Bachelors for this work) but had few job opportunities on graduation, except teaching or being a computer. Whatever work was undertaken was inherently short-term as women were expected to leave the work force on marriage, to focus on motherhood.

During the early 20th Century, quantitative work was seen to be feminine and qualitative work required the rigour of a man – things have changed in perceptions, haven’t they! The women’s work was grunt work: calculating, microscopy. Then there’s men’s work: designing and analysing. The Wars of the 20th Century changed this by removing men and women stepping into the roles of men. Notably, women were stereotyped as being better coders in this role because of their computer background. Coding was clerical, performed by a woman under the direction of a male supervisor. This became male typed over time. As programming became more developed over the 50s and 60s and the perception of it as a dark art started to form a culture of asociality. Random hiring processes started to hurt female participation, because if you are hiring anyone then (quitting the speaker) if you could hire a man, why hire a woman? (Sound of grinding teeth from across the auditorium as we’re all being reminded of stupid thinking, presented very well for our examination by Elizabeth.)

CS itself stared being taught elsewhere but became its own school-discipline in the 60s and 70s, with enrolment and graduation of women matching that of physics very closely. The development of the PC and its adoption in the 80s changed CS enrolments in the 80s and CS1 became a weeder course to keep the ‘under qualified’ from going on to further studies in Computer Science. This then led to fewer non-traditional CS students, especially women, as simple changes like requiring mathematics immediately restricted people without full access to high quality education at school level.

In the 90s, we all went mad and developed hacker culture based around the gamer culture, which we already know has had a strongly negative impact on female participation – let’s face it, you don’t want to be considered part of a club that you don’t like and goes to effort to say it doesn’t welcome you. This led to some serious organisation of women’s groups in CS: Anita Borg Institute, CRA-W and the Grace Hopper Celebration.

Enrolments kept cycling. We say an enrolment boom and bust (including greater percentage of women) that matched the dot-com bubble. At the peak, female enrolment got as high as 30% and female faculty also increased. More women in academia corresponded to more investigation of the representation of women in Computer Science. It took quite a long time to get serious discussions and evidence identifying how systematic the under-representation is.

Over these different decades, women had very different experiences. The first generation had a perception that they had to give up family, be tough cookies and had a pretty horrible experience. The second generation of STEM, in 80s/90s, had female classmates and wanted to be in science AND to have families. However, first generation advisers were often very harsh on their second generation mentees as their experiences were so dissimilar. The second generation in CS doesn’t match neatly that of science and biology due to the cycles and the negative nerd perception is far, far stronger for CS than other disciplines.

Now to the third generation, starting in the 00s, outperforming their male peers in many cases and entering a University with female role models. They also share household duties with their partners, even when both are working and family are involved, which is a pretty radical change in the right direction.

If you’re running a mentoring program for incoming women, their experience may be very. very different from those of the staff that you have to mentor them. Finally, learning from history is essential. We are seeing more students coming in than, for a number of reasons, we may be able to teach. How will we handle increasing enrolments without putting on restrictions that disproportionately hurt our under-represented groups? We have to accept that most of our restrictions actually don’t apply in a uniform sense and that this cannot be allowed to continue. It’s wrong to get your restrictions in enrolment at a greater expense on one group when there’s no good reason to attack one group over another.

One of the things mentioned is that if you ask people to do something because of they are from group X, and make this clear, then they are less likely to get involved. Important note: don’t ask women to do something because they’re women, even if you have the intention to address under-representation.

The second paper, “Cultural Appropriation of Computational Thinking Acquisition Research: Seeding Fields of Diversity”, presented by Martha Serra, who is from Brazil and good luck to them in the World Cup tonight! Brazil adapted scalable game design to local educational needs, with the development of a web-ased system “PoliFacets”, seeding the reflection of IT and Educational researchers.

Brazil is the B in BRICS, with nearly 200 million people and the 5th largest country in the World. Bigger than Australia! (But we try harder.) Brazil is very regionally diverse: rain forest, wetlands, drought, poverty, Megacities, industry, agriculture and, unsurprisingly, it’s very hard to deal with such diversity. 80% of youth population failed to complete basic education. Only 26% of the adult population reach full functional literacy. (My jaw just dropped.)

Scalable Game Design (SGD) is a program from the University of Colorado in Boulder, to motivate all students in Computer Science through game design. The approach uses AgentSheets and AgentsCubes as visual programming environments. (The image shown was of a very visual programming language that seemed reminiscent of Scratch, not surprising as it is accepted that Scratch picked up some characteristics from AgentSheets.)

The SGD program started as an after-school program in 2010 with a public middle school, using a Geography teacher as the program leader. In the following year, with the same school, a 12-week program ran with a Biology teacher in charge. Some of the students who had done it before had, unfortunately, forgotten things by the next year.  The next year, a workshop for teachers was introduced and the PoliFacets site. The next year introduced more schools, with the first school now considered autonomous, and the teacher workshops were continued. Overall, a very positive development of sustainable change.

Learners need stimulation but teachers need training if we’re going to introduce technology – very similar to what we learned in our experience with digital technologies.

The PolFacets systems is a live documentation web-based system used to assist with the process. Live demo not available as the Brazilian corner of internet seems to be full of football. It’s always interesting to look at a system that was developed in a different era – it makes you aware how much refactoring goes into the IDEs of modern systems to stop them looking like refugees from a previous decade. (Perhaps the less said about the “Mexican Frogger” game the better…)

The final talk (for both this session and the day) was “Apps for Social Justice: Motivating Computer Science Learning with Design and Real-World Problem Solving”, presented by Sarah Van Wart. Starting with motivation, tech has diversity issues, with differential access and exposure to CS across race and gender lines. Tech industry has similar problems with recruiting and retaining more diverse candidates but there are also some really large structural issues that shadow the whole issue.

Structurally, white families have 18-20 times the wealth of Latino and African-American people, while jail population is skewed the opposite way. The schools start with the composition of the community and are supposed to solve these distribution issues, but instead they continue to reflect the composition that they inherited. US schools are highly tracked and White and Asian students tend to track into Advanced Placement, where Black and Latino students track into different (and possibly remedial) programs.

Some people are categorically under-represented and this means that certain perspectives are being categorically excluded – this is to our detriment.

The first aspect of the theoretical prestige is Conceptions of Equity. Looking at Jaime Escalante, and his work with students to do better at the AP calculus exam. His idea of equity was access, access to a high-value test that could facilitate college access and thus more highly paid careers. The next aspect of this was Funds of Knowledge, Gonzalez et al, where focusing on a white context reduces aspects of other communities and diminishes one community’s privilege. The third part, Relational Equity (Jo Boaler), reduced streaming and tracking, focusing on group work, where each student was responsible for each student’s success. Finally,Rico Gutstein takes a socio-political approach with Social Justice Pedagogy to provide authentic learning frameworks and using statistics to show up the problems.

The next parts of the theoretical perspective was  Computer Science Education, and Learning Sciences (socio-cultrual perspective on learning, who you are and what it means to be ‘smart’)

In terms of learning science, Nasir and Hand, 2006, discussed Practice-linked Identities, with access to the domain (students know what CS people do), integral roles (there are many ways to contribute to a CS project) and self-expression and feeling competent (students can bring themselves to their CS practice).

The authors produced a short course for a small group of students to develop a small application. The outcome was BAYP (Bay Area Youth Programme), an App Inventor application that queried a remote database to answer user queries on local after-school program services.

How do we understand this in terms of an equity intervention? Let’s go back to Nasir and Hand.

  1. Access to the domain: Design and data used together is part of what CS people do, bridging students’ concepts and providing an intuitive way of connecting design to the world. When we have data, we can get categories, then schemas and so on. (This matters to CS people, if you’re not one. 🙂 )
  2. Integral Roles: Students got to see the importance of design, sketching things out, planning, coding, and seeing a segue from non-technical approaches to technical ones. However, one other very important aspect is that the oft-derided “liberal arts” skills may actually be useful or may be a good basis to put coding upon, as long as you understand what programming is and how you can get access to it.
  3. Making a unique contribution: The students felt that what they were doing was valuable and let them see what they could do.

Take-aways? CS can appeal to so many peopleif we think about how to do it. There are many pathways to help people. We have to think about what we can be doing to help people. Designing for their own community is going to be empowering for people.

Sarah finished on some great questions. How will they handle scaling it up? Apprenticeship is really hard to scale up but we can think about it. Does this make students want to take CS? Will this lead to AP? Can it be inter-leaved with a project course? Could this be integrated into a humanities or social science context? Lots to think about but it’s obvious that there’s been a lot of good work that has gone into this.

What a great session! Really thought-provoking and, while it was a reminder for many of us how far we have left to go, there were probably people present who had heard things like this for the first time.


ITiCSE 2014: Monday, Keynote 1, “New Technology, New Learning?” #ITiCSE2014 #ITiCSE

This keynote was presented by Professor Yvonne Rogers, from University College of London. The talk was discussing how we could make learning more accessible and exciting for everyone and encourage students to think, to create and share our view. Professor Rogers started by sharing a tweet by Conor Gearty on a guerrilla lecture, with tickets to be issued at 6:45pm, for LSE students. (You can read about what happened here.) They went to the crypt of Westminster Cathedral and the group, split into three smaller groups, ended up discussing the nature of Hell and what it entailed. This was a discussion on religion but, because of the way that it was put together, it was more successful than a standard approach – context shift, suspense driving excitement and engagement. (I wonder how much suspense I could get with a guerrilla lecture on polymorphism… )

Professor Rogers says that suspense matters, as the students will be wondering what is coming next, and this will hopefully make them more inquisitive and thus drive them along the path to scientific enquiry. The Ambient Wood was a woodland full of various technologies for student pairs, with technology and probes, an explorative activity. You can read about the Ambient Wood here. The periscope idea ties videos into the direction that you are looking – a bit like Google Glass without a surveillance society aspect (a Woodopticon?). (We worked on similar ideas at Adelaide for an early project in the Arts Precinct to allow student exploration to drive the experience in arts, culture and botanical science areas.) All of the probes were recorded in the virtual spatial environment matching the wood so that, after the activity, the students could then look at what they did. Thus, a group of 10-12 year olds had an amazing day exploring and discovering, but in a way that was strongly personalised, with an ability to see it from the bird’s eye view above them.

And, unsurprisingly, we moved on to MOOCs, with an excellent slide on MOOC HYSTERIA. Can we make these as engaging as the guerrilla lecture or the ambient wood?

MOOCs, as we know, are supposed to increase our reach and access to education but, as Professor Rogers noted, it is also a technology that can make the lecturer a “bit of a star”. This is one of the most honest assessments of some of the cachet that I’ve heard – bravo, Professor Rogers. What’s involved in a MOOC? Well, watching things, doing quizzes, and there’s probability a lot of passive, rather than active, learning. Over 60% of the people who sign up to do a MOOC, from the Stanford experience, have a degree – doing Stanford for free is a draw for the already-degreed. How can we make MOOCs fulfil their promise, give us good learning, give us active learning and so on? Learning analytics give us some ideas and we can data mine to try and personalise the course to the student. But this has shifted what our learning experience is and do we have any research to show the learning value of MOOCs?

In 2014, 400 students taking a Harvard course:

  1. Learned in a passive way
  2. Just want to complete
  3. Take the easy option
  4. Were unable to apply what they learned
  5. Don’t reflect on or talk to their colleagues about it.

Which is not what we want? What about the Flipped Classroom? Professor Rogers attributed this to Khan but I’m not sure I agree with this as there were people, Mazur for example, who were doing this in Peer Instruction well before Khan – or at least I thought so. Corrections in the questions please! The idea of the flip is that we don’t have content delivery in lectures with the odd question – we have content beforehand and questions in class. What is the reality?

  1. Still based on chalk and talk.
  2. Is it simply a better version of a bad thing?
  3. Are students more motivated and more active?
  4. Very labour-intensive for the teacher.

So where’s the evidence? Well, it does increase interaction in class between instructors and students. It does allow for earlier identification of misconceptions. Pierce and Fox, 2012, found that it increased exam results for pharmacology students. It also fostered critical thinking in case scenarios. Maybe this will work for 10s-100s – what about classes of thousands? Can we flip to this? (Should we even have classes of this size is another good question)

Then there’s PeerWise, Paul Denny (NZ), where there is active learning in which students create questions, answer them and get feedback. Students create the questions and then they get to try other student’s questions and can then rate the question and rate the answer. (We see approaches like this, although not as advanced, in other technologies such as Piazza.)

How effective is this? Performance in PeerWise correlated with exam marks (Anyadi, Green and Tang, 2013), with active student engagement. It’s used for revision before the exams, and you get hihg-quality questions and answers, while supporting peer interaction. Professor Rogers then showed the Learning Pyramid, from the National Training Laboratories, Bethel, Maine. The PeerWise system plays into the very high retention area.

Professor Rogers then moved on to her own work, showing us a picture of the serried rank nightmare of a computer-based classroom: students in rows, isolated and focused on their screens. Instead of ‘designing for one’, why don’t we design to orchestrate shared activities, with devices that link to public displays and can actively foster collaboration. One of Professor Rogers’ students is looking at ways to share simulations across tablets and screens. This included “4Decades“, a a simulation of climate management, with groups representing the different stakeholders to loo at global climate economics. We then saw a video that I won’t transcribe. The idea is that group work encourages discussion, however we facilitate it, and this tends to leading to teaching others in the sharing of ideas. Another technology that Professor Rogers’ group have developed in this space is UniPad: orchestrating collaborate activities across multiple types of devices, with one device per 6-7 students, and used in classes without many researchers present. Applications of this technology include budgeting for students (MyBank), with groups interacting and seeing the results on a public display. Given how many students operate in share houses collaboratively, this is quite an interesting approach to the problem. From studies on this, all group members participated and used the tablet as a token for discussion, taking ownership of a part of the problem. This also extended to reflection on other’s activities, including identifying selfish behaviour on the part of other people. (Everyone who has had flatmates is probably groaning at the moment. Curse you, Love Tarot Pay-By-The-Minute Telephone Number, which cost me and my flatmates a lot of dollars after a flatmate skipped out on us.)

The next aspect Professor Rogers discussed was physical creation toolkits, such as MaKey MaKey, where you can build alternative input for a computer, based on a simple printed circuit board with alligator clips and USB cables. The idea is simple: you can turn anything you like into a keyboard key. Demonstrations included a banana space bar, a play dough MarioKart gamepad, and many other things (a water bowl in front of the machine became a cat-triggered photo booth). This highlights one of the most important aspects of thinking about learning: learning for life. How can we keep people interested in learning in the face of busy, often overfull, lives when many people still think about learning as something that had to be endured on their pathway into the workforce? (Paging my climbing friends with their own climbing wall: you could make the wall play music if you wanted to. Just saying.)

One of the computers stopped working during a trial of the MaKey MaKey system with adult learners and the collaboration that ensued changed the direction of the work and more people were assigned to a single kit. Professor Rogers showed a small video of a four-person fruit orchestra of older people playing Twinkle Twinkle Little Star. (MORE KIWI!) This elicited a lot of ideas, including for their grandchildren and own parent, transforming exercise to be more fun, to help people learn fundamental knowledge skills and give good feedback. We often heavily intervene in the learning experience and the reflection of the Fruit Orchestra was that intervening less in self-driven activities such as MaKey MaKey might be a better way to go, to increase autonomy and thus drive engagement.

Next was the important question: How can we gets to create and code, where coding is just part of the creating? Can we learn to code differently beyond just choosing a particular language? We have many fascinating technologies but what is the suite of tools over the top that will drive creativity and engagement in this area, to produce effective learning? The short video shown demonstrated a pop-out prefabricated system, where physical interfaces and gestures across those represented coding instructions: coding without any typing at all. (Previous readers will remember my fascination with pre-literate programming.) This early work, electronics on a sheet, is designed to be given away because the production cost is less than 3 Euros. The project is called “code me” from University College London and is designed to teach logic without people realising it: the fundamental building block of computational thinking. Future work includes larger blocks with Bluetooth input and sensors. (I can’t find a web page for this.)

What role should technology play in learning? Professor Rogers mentioned thinking about this in two ways. The inside learning using technology to think about the levels students to reach to foster attainment: personalise, monitor, motivate, flexible, adaptive. The outside learning approach is to work with other people away from the screen: collaborate, create, connect, reflect and play. Professor Rogers believes that the choice is ours but that technology should transform learning to make it active, creative, collaborative, exciting (some other things I didn’t catch) and to recognise the role of suspense in making people think.

An interesting and thought-provoking keynote.

 


The Antagonistic Classroom Is A Dinosaur

It’s been a while since I’ve posted but, in that time, I’ve been doing a lot of reading and a lot of thinking. I’m aware that as a CS Ed person whose background is in CS rather than Ed is that I have a lot of catching up to do in terms of underlying theory and philosophy. I’ve been going further back to look at the changes in education, from the assumption that a student is a blank slate (tabula rasa) to be written on (or an empty bank account to be filled) rather than as a person to be worked with. As part of my search I’ve been reading a lot and what has become apparent is how long people have been trying to change education in order to improve the degree and depth of learning and student engagement. It’s actually mildly depressing to track the last 250 years of people trying to do anything other than rote learning, serried ranks of silent students and cultural crystallisation. As part of this reading, and via Rousseau and Hegel, I’ve wandered across the early works of Karl Marx who, before the proletariat began its ongoing efforts to not act as he had modelled them, was thinking about the role of work and life. In essence, if what you are doing is not really a part of your life then you are working at something alien in order to earn enough to live – in order to work again another day. I’m not a Marxist, by any stretch of the imagination and for a variety of reasons, but this applies well for the way that many people see study as well. For many people, education is an end in itself, something to be endured in order to move on to the next stage, which is working in order to live until you stop working and then you die.

When you look at the methods that, from evidence and extensive research, now appear to be successful in developing student learning, we see something very different from what we have done before: we see cooperation, mutual respect, self-determination and a desire to learn that is facilitated by being part of the educational system. In this system, the school is not a cage for students and a trap for the spirit of education. However, this requires a distinct change in the traditional roles between student and teacher, and it’s one that some teachers still aren’t ready for and many students haven’t been prepared for. The future is creative and it’s now time to change our educational system to fully support that.

Ultimately, many of the ways that we educate place the teacher in a role of judgement and opposition to the student: students compete in order to secure the best marks, which may require them to withhold information from each other, and they must convince the teacher of their worth in order to achieve the best results. In order to maintain the mark separation, we have to provide artificial mechanisms to ensure that we can create an arbitrary separation, above the concept of competency, by having limited attempts on assignments and late penalties. This places the teacher in opposition to the student, an adversary who must be bested. Is this really what we want in what should be a mutually enriching relationship? When we get it right, the more we learn, the more we can teach and hence the more everyone learns.

If we search for the opposite of an antagonist, we find the following words: ally, helper, supporter and friend. These are great words but they evoke roles that we can’t actually fill unless we step out from behind the lectern and the desk and work with our students. An ally doesn’t force students to compete against each other for empty honours that only a few can achieve. A helper doesn’t tell students that the world works as if every single piece of assignment work is the most important thing ever assigned. A supporter develops deep structures that will hold up the person and their world for their whole life. A friend has compassion for the frailties of the humans around them – although they still have to be honest as part of that friendship.

My students and I win together when they achieve things. I don’t need to be smarter than them in order to prove anything and I don’t need them to beat me before they can demonstrate that they’re ready to go out into the world. If I held a pebble out in my hand and asked the student how they could get it, I would hope that they would first ask me if they could have it, rather than attempting some bizarre demonstration of hand-eye coordination. Why compete when we could all excel together?

We stand in exciting times, where knowledge can be shared widely and semi-instantly, but we won’t see the best of what we can do with this until we see an antagonistic classroom for the dinosaur that it is and move on.


CSEDU, Day 1, Keynote 2, “Mathematics Teaching: is the future syncretic?” (#csedu14 #csedu #AdelEd)

This is an extension of the position paper that was presented this morning. I must be honest and say that I have a knee-jerk reaction when I run across titles like this. There’s always the spectre of Rand or Gene Ray in compact phrases of slightly obscure terminology. (You should probably ignore me, I also twitch every time I run across digital hermeneutics and that’s perfectly legitimate.) The speaker is Larissa Fradkin who is trying to improve the quality of mathematics teaching and overall interest in mathematics – which is a good thing and so I should probably be far more generous about “syncretic”. Let’s review the definition of syncretic:

Again, from Wikipedia, Syncretism /ˈsɪŋkrətɪzəm/ is the combining of different, often seemingly contradictory beliefs, while melding practices of various schools of thought. (The speaker specified this to religious and philosophical schools of thought.)

There’s a reference in the talk to gnosticism, which combined oriental mysticism, Judaism and Christianity. Apparently, in this talk we are going to have myths debunked regarding the Maths Wars of Myths, including traditionalist myths and constructivist myths. Then discuss the realities in the classroom.

Two fundamental theories of learning were introduced: traditionalist and constructivist. Apparently, these are drummed into poor schoolteachers and yet we academics are sadly ignorant of these. Urm. You have to be pretty confident to have a go at Piaget: “Piaget studied urchins and then tried to apply it to kids.” I’m really not sure what is being said here but the speaker has tried to tell two jokes which have fallen very flat and, regrettably, is making me think that she doesn’t quite grasp what discovery learning is. Now we are into Guided Teaching and scaffolding with Vygotsky, who apparently, as a language teacher, was slightly better than a teacher of urchins.

The first traditionalist myth is that intelligence = implicit memory (no conscious awareness) + basic pattern recognition. Oh, how nice, the speaker did a lot of IQ tests and went from 70 to 150 in 5 tests. I don’t think many people in the serious educational community places much weight  on the assessment of intelligence through these sorts of test – and the objection to standardised testing is coming from the edu research community of exactly those reasons. I commented on this speaker earlier and noted that I felt that she was having an argument that was no longer contemporary. Sadly, my opinion is being reinforced. The next traditionalist myth is that mathematics should be taught using poetry, other mnemonics and coercion.

What? If the speaker is referring to the memorisation of the multiplication tables, we are taking about a definitional basis for further development that occupies a very short time in the learning phase. We are discussing a type of education that is already identified as negative as if the realisation that mindless repetition and extrinsic motivational factors are counter-productive. Yes, coercion is an old method but let’s get to what you’re proposing as an alternative.

Now we move on to the constructivist myths. I’m on the edge of my seat. We have a couple of cartoons which don’t do anything except recycle some old stereotypes. So, the first myth is “Only what students discover for themselves is truly learned.” So the problem here is based on Rebar, 2007, met study. Revelation: Child-centred, cognitively focused and open classroom approaches tend to perform poorly.

Hmm, not our experience.

The second myth is both advanced and debunked by a single paper, that there are only two separate and distinct ways to teach mathematics: conceptual understanding and drills. Revelation: Conceptual advanced are invariably built on the bedrock of technique.

Myth 3: Math concepts are best understood and mastered when presented in context, in that way the underlying math concept will follow automatically. The speaker used to teach with engineering examples but abandoned them because of the problem of having to explain engineering problems, engineering language and then the problem. Ah, another paper from Hung-Hsi Wu, UCB, “The Mathematician and Mathematics Education Reform.” No, I really can’t agree with this as a myth. Situated learning is valid and it works, providing that the context used is authentic and selected carefully.

Ok, I must confess that I have some red flags going up now – while I don’t know the work of Hung-Hsi Wu, depending on a single author, especially one whose revelatory heresy is close to 20 years old, is not the best basis for a complicated argument such as this. Any readers with knowledge in this should jump on to the comments and get us informed!

Looking at all of these myths, I don’t see myths, I see straw men. (A straw man is a deliberately weak argument chosen because it is easy to attack and based on a simplified or weaker version of the problem.)

I’m in agreement with many of the outcomes that Professor Fradkin is advocating. I want teachers to guide but believe that they can do it in the constriction of learning environments that support constructivist approaches. Yes, we should limit jargon. Yes, we should move away from death-by-test. Yes, Socratic dialogue is a great way to go.

However, as always, if someone says “Socratic dialogue is the way to go but I am not doing it now” then I have to ask “Why not?” Anyone who has been to one of my sessions knows that when I talk about collaboration methods and student value generation, you will be collaborating before your seat has had a chance to warm up. It’s the cornerstone of authentic teaching that we use the methods that we advocate or explain why they are not suitable – cognitive apprenticeship requires us to expose our selves as we got through the process we’re trying to teach!

Regrettably, I think my initial reaction of cautious mistrust of the title may have been accurate. (Or I am just hopelessly biassed by an initial reaction although I have been trying to be positive.) I am trying very hard to reinterpret what has been said. But there is a lot of anecdote and dependency upon one or two “visionary debunkers” to support a series of strawmen presented as giant barriers to sensible teaching.

Yes, listening to students and adapting is essential but this does not actually require one to abandon constructivist or traditionalist approaches because we are not talking about the pedagogy here, we’re talking about support systems. (Your take on that may be different.)

There is some evidence presented at the end which is, I’m sorry to say, a little confusing although there has obviously been a great deal of success for an unlisted, uncounted number and unknown level of course – success rates improved from 30 passing to 70% passing and no-one had to be trained for the exam. I would very much like to get some more detail on this as claiming that the syncretic approach is the only way to reach 70% is essential is a big claim. Also, a 70% pass rate is not all that good – I would get called on to the carpet if I did that for a couple of offerings. (And, no, we don’t dumb down the course to improve pass rate – we try to teach better.)

Now we move into on-line techniques. Is the flipped classroom a viable approach? Can technology “humanise” the classroom? (These two statements are not connected, for me, so I’m hoping that this is not an attempt to entail one by the other.) We then moved on to a discussion of Khan, who Professor Fradkin is not a fan of, and while her criticisms of Khan are semi-valid (he’s not a teacher and it shows), her final statement and dismissal of Khan as a cram-preparer is more than a little unfair and very much in keeping with the sweeping statements that we have been assailed by for the past 45 minutes.

I really feel that Professor Fradkin is conflating other mechanisms with blended and flipped learning – flipped learning is all about “me time” to allow students to learn at their own pace (as she notes) but then she notes a “Con” of the Khan method of an absence of “me time”. What if students don’t understand the recorded lectures at all? Well… how about we improve the material? The in-class activities will immediately expose faulty concept delivery and we adapt and try again (as the speaker has already noted). We most certainly don’t need IT for flipped learning (although it’s both “Con” point 3 AND 4 as to why Khan doesn’t work), we just need to have learning occur before we have the face-to-face sessions where we work through the concepts in a more applied manner.

Now we move onto MOOCs. Yes, we’re all cautious about MOOCs. Yes, there are a lot of issues. MOOCs will get rid of teachers? That particular strawman has been set on fire, pushed out to sea, brought back, set on fire again and then shot into orbit. Where they set it on fire again. Next point? Ok, Sebastian Thrun made an overclaim that the future will have only 10 higher ed institutions in 50 years. Yup. Fire that second strawman into orbit. We’ve addressed Professor Thrun before and, after all, he was trying to excite and engage a community over something new and, to his credit, he’s been stepping back from that ever since.

Ah, a Coursera course that came from a “high-quality” US University. It is full of imprecise language, saying How and not Why, with a Monster generator approach. A quick ad hominen attack on the lecturer in the video (He looked like he had been on drugs for 10 years). Apparently, and with no evidence, Professor Fradkin can guarantee that no student picked up any idea of what a function was from this course.

Apparently some Universities are becoming more cautious about MOOCs. Really.

I’m sorry to have editorialised so badly during this session but this has been a very challenging talk to listen to as so much of the underlying material has been, to my understanding, misrepresented at least. A very disappointing talk over all and one that could have been so much better – I agree with a lot of the outcomes but I don’t really think that this is not the way to lead towards it.

Sadly, already someone has asked to translate the speaker’s slides into German so that they can send it to the government! Yes, text books are often bad and a lack of sequencing is a serious problem. Once again I agree with the conclusion but not the argument… Heresy is an important part of our development of thought, and stagnation is death, but I think that we always need to be cautious that we don’t sensationalise and seek strawmen in our desire to find new truths that we have to reach through heresy.

 


Education and Paying Back (#AdelEd #CSER #DigitalTechnologies #acara #SAEdu)

On Monday, the Computer Science Education Research Group and Google (oh, like you need a link) will release their open on-line course to support F-6 Primary school teachers in teaching the new Digital Technologies curriculum. We are still taking registrations so please go the course website if you want to sign up – or just have a look! (I’ve blogged about this recently as part of Science meets Parliament but you can catch it again here.) The course is open, on-line and free, released under Creative Commons so that the only thing people can’t do is to try and charge for it. We’re very excited and it’s so close to happening, I can taste it!

Here’s that link again – please, sign up!

I’m posting today for a few reasons. If you are a primary school teacher who wants help teaching digital technologies, we’d love to see you sign up and join our community of hundreds of other people who are thinking the same thing. If you know a primary school teacher, or are a principal for a primary school, and think that this would interest people – please pass it on! We are most definitely not trying to teach teachers how to teach (apart from anything else, what presumption!) but we’re hoping that what we provide will make it easier for teachers to feel comfortable, confident and happy with the new DT curriculum requirements which will lead to better experiences all ’round.

My other reason is one that came to me as I was recording my introduction section for the on-line course. In that brief “Oh, what a surprise there’s a camera” segment, I note that I consider the role of my teachers to have been essential in getting me to where I am today. This is what I’d like to do today: explicitly name and thank a few of my teachers and hope that some of what we release on Monday goes towards paying back into the general educational community.

You know who this is for.

You know who this is for.

My first thanks go to Mrs Shand from my Infant School in England. I was an early reader and, in an open plan classroom, she managed to keep me up with the other material while dealing with the fact that I was a voracious reader who would disappear to read at the drop of a hat. She helped to amplify my passion for reading, instead of trying to control it. Thank you!

In Australia, I ran into three people who were crucial to my development. Adam West was interested in everything so Grade 5 was full of computers (my first computing experience) because he arranged to borrow one and put it into the classroom in 1978, German (I can still speak the German I learnt in that class) and he also allowed us to write with nib and ink pens if we wanted – which was the sneakiest way to get someone’s handwriting and tidiness to improve that I have ever seen. Thank you, Adam!  Mrs Lothian, the school librarian, also supported my reading habit and, after a while, all of the interesting books in the library often came through me very early on because I always returned them quickly and in good condition but this is where I was exposed to a whole world of interesting works: Nicholas Fisk, Ursula Le Guin and Susan Cooper not being the least of these. Thank you! Gloria Patullo (I hope I’ve spelt that correctly) was my Grade 7 teacher and she quickly worked out that I was a sneaky bugger on occasion and, without ever getting angry or raising a hand, managed to get me to realise that being clever didn’t mean that you could get away with everything and that being considerate and honest were the most important elements to alloy with smart. Thank you! (I was a pain for many years, dear reader, so this was a long process with much intervention.)

Moving to secondary school, I had a series of good teachers, all of whom tried to take the raw stuff of me and turn it into something that was happier, more useful and able to take that undirected energy in a more positive direction. I have to mention Ken Watson,  Glenn Mulvihill, Mrs Batten, Dr Murray Thompson, Peter Thomas, Dr Riceman, Dr Bob Holloway, Milton Haseloff (I still have fossa, -ae, [f], ditch, burned into my brain) and, of course, Geoffrey Bean, headmaster, strong advocate of the thinking approaches of Edward de Bono and firm believer in the importance of the strength one needs to defend those who are less strong. Thank you all for what you have done, because it’s far too much to list here without killing the reader: the support, the encouragement, the guidance, the freedom to try things while still keeping a close eye, the exposure to thinking and, on occasion, the simple act of sitting me down to get me to think about what the heck I was doing and where I was going. The fact that I now work with some of them, in their continuing work in secondary education, is a wonderful thing and a reminder that I cannot have been that terrible. (Let’s just assume that, shall we? Moving on – rapidly…)

Of course, it’s not just the primary and secondary school teachers who helped me but they are the ones I want to concentrate on today, because I believe that the freedom and opportunities we offer at University are wonderful but I realise that they are not yet available to everyone and it is only by valuing, supporting and developing primary and secondary school education and the teachers who work so hard to provide it that we can go further in the University sector. We are lucky enough to be a juncture where dedicated work towards the national curriculum (and ACARA must be mentioned for all the hard work that they have done) has married up with an Industry partner who wants us all to “get” computing (Thank you, Google, and thank you so much, Sally and Alan) at a time when our research group was able to be involved. I’m a small part of a very big group of people who care about what happens in our schools and, if you have children of that age, you’ve picked a great time to send them to school. 🙂

I am delighted to have even a small opportunity to offer something back into a community which has given me so much. I hope that what we have done is useful and I can’t wait for it to start.

SIGSCE Day 2, “Focus on K-12: Informal Education, Curriculum and Robots”, Paper 1, 3:45-5:00, (#SIGCSE2014)

The first paper is “They can’t find us: The Search for Informal CS Education” by Betsy DiSalvo, Cecili Reid, Parisa Khanipour Roshan, all from Georgia Tech. (Mark wrote this paper up recently.) There are lots of resources around, MOOCs, on-line systems tools, Khan academy and Code Academy and, of course the aggregators. If all of this is here, why aren’t we getting the equalisation effects we expect?

Well, the wealth and the resource-aware actually know how to search and access these, and are more aware of them, so the inequality persists. The Marketing strategies are also pointed at this group, rather than targeting those needing educational equity. The cultural values of the audiences vary. (People think Scratch is a toy, rather than a useful and pragmatic real-world tool.) There’s also access – access to technical resource, social support for doing this and knowledge of the search terms. We can address this issues by research mechanisms to address the ignored community.

Children’s access to informal learning is through their parents so how their parents search make a big difference. How do they search? The authors set up a booth to ask 16 parents in the group how they would do it. 3 were disqualified for literacy or disability reasons (which is another issue). Only one person found a site that was relevant to CS education. Building from that, what are the search terms that they are using for computer learning and why aren’t hey coming up with good results. The terms that parents use supported this but the authors also used Google insights to see what other people were using. The most popular terms for the topic, the environment and the audience. Note: if you search for kids in computer learning you get fewer results than if you search for children in computer learning. The three terms that came up as being best were:

  • kids computer camp
  • kids computer classes
  • kids computer learning

The authors reviewed across some cities to see if there was variation by location for these search terse. What was the quality of these? 191 out of 840 search results were unique and relevant, with an average of 4.5 per search.

(As a note, MAN, does Betsy talk and present quickly. Completely comprehensible and great but really hard to transcribe!)

Results included : Camp, after school program, camp/afterschool, higher education, online activities, online classes/learning, directory results (often worse than Google), news, videos or social networks (again the quality was lower). Computer camps dominated what you could find on these search results – but these are not an option for low-income parents at $500/week so that’s not a really useful resource for them. Some came up for after school and higher ed in the large and midsize cities, but very little in the smaller cities. Unsurprisingly, smaller cities and lower socio-economic groups are not going to be able to find what they need to find, hence the inequality continues. There are many fine tools but NONE of them showed up on the 800+ results.

Without a background in CS or IT, you don’t know that these things exist and hence you can’t find it for your kids. Thus, these open educational resources are less accessible to these people, because they are only accessible through a mechanism that needs extra knowledge. (As a note, the authors only looked at the first two pages because “no-one looks past that”. 🙂 ) Other searches for things like kids maths learning, kids animal learning or kids physics learning turned up 48 out of 80 results (average of 16 unique results per search term), where 31 results were online, 101 had classes at uni – a big difference.

(These studies were carried out before code.org. Running the search again for kids computer learning does turn up code.org. Hooray, there is progress! If the study was run again, how much better would it be?)

We need to take a top down approach to provide standards for keywords and search terms, partnering with formal education and community programs. The MOOCs should talk to the Educational programming community, both could talk to the tutorial community and then we can throw in the Aggregators as well. Distant islands that don’t talk are just making this problem worse.

The bottom-up approach is getting an understanding of LSEO parenting, building communities and finding out how people search and making sure that we can handle it. Wow! Great talk but I think my head is going to explode!

During question time, someone asked why people aren’t more creative with their searches. This is, sadly, missing the point that, sitting in this community, we are empowered and skilled in searching. The whole point is that people outside of our community aren’t guaranteed to be able to find a way too be creative. I guess the first step is the same as for good teaching, putting ourselves in the heads of someone who is a true novice and helping to bring them to a more educated state.

 

 


Getting it wrong, offensively so. The scales ARE biassed.

6874balance_scale

Mark Guzdial has put out some excellent posts recently on Barbara Ericson’s ongoing work on analysing AP CS exam attempts and results across the US. Unsurprisingly, to those of us who see the classrooms on a day-to-day basis, women are grossly underrepresented. In this interview, Barbara is quoted:

Barbara Ericson, director of computing outreach at Georgia Tech, has made a startling claim. She said not one female student in three states – Mississippi, Montana and Wyoming — took the Advanced Placement exam in computer science last year.

Ericson appeared on Weekend Express to discuss the gender gap and explains why more women aren’t interested in computer science.

Now, I’m not going to rehash all of these posts but I did want to pick on one blogger who took the AP data and then, as far as I’m concerned, not only got it wrong by making some fundamental interpretational errors  but managed to do so in a way that so heavily reeked of privilege that I’m going to call it out.

I hesitate to link to the article on the Huffington Post but it’s only fair that you should read it to see what you think, even though it will generate traffic. The article is called “Memo to Chicken Little: Female Scientists Do Roam Among Us, and Gasp! Some Even Wear Lipstick”. So before we’ve even started, we’ve got one good stereotype going in the title.

Look, I’m not planning to drag apart the whole article but I will pick on one point that the author makes because it really irritates me. Here’s the paragraph:

As a woman who likes science as a bystander but chose not to pursue it professionally, I’ve got a couple of problems with all this handwringing. Mostly, well-intentioned as it is, it implies that women need “help” choosing a field of study. High school girls are exposed to exactly the same science and math courses they need to graduate as boys are, but in the eyes of the handwringers, girls are either too shallow or simple to choose for themselves, or need to be socially engineered into the correct balance of male vs. female, regardless of their choices. I appreciate your concern, but frankly, it’s pretty demeaning.

Frankly, I’ve never seen a more disingenuous interpretation of attempts to undo and reverse the systematic anti-female bias that is built into our culture. I’ve never seen anyone who is trying to address this problem directly or indirectly label girls as shallow or too simple to choose – this is a very unpleasant strawman, constructed to make those of us who are trying to address a bias look like we’re the ones with the attitude problem. We don’t need to socially engineer girls into the correct balance, we need to engineer society to restore the balance and articles like this, which make it appear that women are deliberately choosing to avoid STEM, are unwelcome, unnecessary and unfair to the many young women who are being told that the way that our society works is the way that it should work.

Need I remind people of stereotype threat? The PNAS study that shows that women are as automatically likely to harshly judge women and lessen their rewards as their male colleagues? Looking at the AP attendance and performance doesn’t show equality, it shows the outcome of a systematically biased system.

To say that “High school girls are exposed to exactly the same science and math courses they need to graduate as boys are” is a difficult statement. Yes, women rack up roughly the same number of course credits but on the critical measurement of whether they choose to go on and pursue a profession? No, something breaks here. The AP test is a great measure because it is an Advanced Placement exam and your intention is to use this to go further.  Is there clear evidence of far fewer women, as a percentage, going on from high school to college in STEM despite scoring the same kinds of grades? Yes. Is there evidence that some of these problems (anxiety about maths, for example) can start with perceptions of teachers in primary school? Yes. Is there a problem?

Yes.

And the question is always, if your previous exposure has not been fair, then is it reasonable to pick an arbitrary level of course that would be fair to people who haven’t been discriminated against? For years, racism was justified by culturally-based testing that could not be performed at the same level by people outside the culture – which was then used to restrict their access to the culture.

To me, that statement about exposure summarises everything that is wrong with glib arguments about constructing equal opportunity. If we’re going for a big job and there’s a corporate ‘interview dinner’ for 20 people, then we’ll all be on our best behaviour at dinner. For someone to lose the job because nobody showed them how to use a finger bowl or because their family uses a knife in the ‘other’ way, is to provide an equal exposure in the present that is blatantly unfair because it doesn’t take into account the redress of previous bias to bring people up to the point where it is really equal opportunity.

I think history supports me in the statement that we have been proved wrong every other time we’ve tried to segregate human ability and talent based on fixed physical abilities that were assigned at birth. Isn’t it about time we started investing all of our effort into producing truly equal opportunity for everyone?


Start with good grapes, don’t mess them up.

“Make no little plans; they have no magic to stir men’s blood and probably themselves will not be realised.” Daniel Burnham

I was watching a film today called “Antiviral”, directed by Brandon Cronenburg, and one of the themes addressed was what we choose to do with technology. Celebrity cell reproduction is the theme of the movie and it is quite bizarre to see a technology that could be so useful (in building new organs and prolonging life) being used to allow people to have the same colds that their idols do. (Because of the rating of this blog, I must state that Antiviral is an adult film and there are themes that I will not discuss here.)

We have many technologies that are powerful and we are developing more of them, daily. We have developed the ability to print human organs (to a limited fashion, although 40 days for a liver is another month of life for someone) and we in the foothills of printing food. Our automated and autonomous systems become more capable and more effective on a daily basis, although Amazon’s drone network won’t be buzzing your house tomorrow.

One of the most profound reasons for education is the requirement to ensure that the operators of powerful things are reasoning, thinking, informed human beings. As humans, we tend to build amplification engines, it’s just what we do, but in so many cases, a good intention is then amplified to a great one, and a malign intention can be amplified to massive and evil result.

Our production processes for food and drink often take a similar form. To make good bread, you grow good wheat in good soil and then you use good yeast, clean conditions and control the oven. You start with good ingredients and you use technology and knowledge to make it better – or to transform it without damage. The same is true of wine. I can make good wine from just about anything but if you want me to make great wine? I have to start with good grapes and then not mess them up!

Good grapes!

Good grapes!

Our technologies are, however, able to go either way. I could burn the bread, cook the yeast, freeze the wine, just as easily if I was poorly trained or if I had malicious intent. Education is not just about training, it’s about preparation for the world in which our students will live. This world is always changing but we have to move beyond thinking about “Driver’s Ed” as a social duty and think about “Resource Ed”, “The Ethics of Cloning” (for example) and all sorts of difficult and challenging issues when we try and teach. We don’t have to present a given viewpoint, by any means, but to ignore the debate and the atmosphere in which we (and I in particular) are training young tertiary students would be to do them a disservice.

This starts young. The sooner we can start trying to grow good students and the sooner that we make our educational systems transform these into wonderful people, the better off we’ll be. The least I would hope for, for any of my students, is that they will always at least think briefly of some of the issues before they do something. They may still choose to be malign, for whatever reason, but let it be then a choice and not from ignorance – but also, let the malign be few and far between and a dying breed!


You want thinkers. Let us produce them.

I was at a conference recently where the room (about 1000 people from across the business and educational world) were asked what they would like to say to everyone in the room, if they had a few minutes. I thought about this a lot because, at the time, I had half an idea but it wasn’t in a form that would work on that day. A few weeks later, in a group of 100 or so, I was asked a similar question and I managed to come up with something coherent. What follows here is a more extended version of what I said, with relevant context.

If I could say anything to the parents and  future employers of my students, it would be to STOP LOOKING AT GRADES as some meaningful predictor of the future ability of the student. While measures of true competency are useful, the current fine-grained but mostly arbitrary measurements of students, with rabid competitiveness and the artificial divisions between grade bands, do not fulfil this purpose. When an employer demands a GPA of X, there is no guaranteed true measure of depth of understanding, quality of learning or anything real that you can use, except for conformity and an ability to colour inside the lines. Yes, there will be exceptional people with a GPA of X, but there will also be people whose true abilities languished as they focused their energies on achieving that false grail. The best person for your job may be the person who got slightly (or much) lower marks because they were out doing additional tasks that made them the best person.

Please. I waste a lot of my time giving marks when I could be giving far more useful feedback, in an environment where that feedback could be accepted and actual positive change could take place. Instead, if I hand back a 74 with comments, I’ll get arguments about the extra mark to get to 75 rather than discussions of the comments – but don’t blame the student for that attitude. We have created a world in which that kind of behaviour is both encouraged and sensible. It’s because people keep demanding As and Cs to somehow grade and separate people that we still use them. I couldn’t switch my degree over to “Competent/Not Yet Competent” tomorrow because, being frank, we’re not MIT or Stanford and people would assume that all of my students had just scraped by – because that’s how we’re all trained.

If you’re an employer then I realise that it’s very demanding but please, where you can, look at the person wherever you can and ask your industrial bodies that feed back to education to focus on ensuring that we develop competent, thinking individuals who can practice in your profession, without forcing them to become grade-haggling bean counters who would cut a group member’s throat for an A.

If you’re a parent, then I would like to ask you to think about joining that group of parents who don’t ask what happened to that extra 1% when a student brings home a 74 or 84. I’m not going to tell you how to raise your children, it’s none of my business, but I can tell you, from my professional and personal perspective, that it probably won’t achieve what you want. Is your student enjoying the course, getting decent marks and showing a passion and understanding? That’s pretty good and, hopefully, if the educators, the parents and the employers all get it right, then that student can become a happy and fulfilled human being.

Do we want thinkers? Then we have to develop the learning environments in which we have the freedom and capability to let them think. But this means that this nonsense that there is any real difference between a mark of 84 and a mark of 85 has to stop and we need to think about how we develop and recognise true measures of competence and suitability that go beyond a GPA, a percentage or a single letter grade.

You cannot contain the whole of a person in a single number. You shouldn’t write the future of a student on such a flimsy structure.
