Verbs and Nouns: Designing a Design

Posted: November 22, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , , | Leave a comment

(Via the frequently delightful but often scatological Lolbrary.)

We have a very bad habit in Computing of ‘verbing the noun’, where we take a perfectly good noun and repurpose it as a verb. If, in the last few weeks, you’ve googled, face booked, photoshopped or IMed, then you know what I mean. (Coining new words like this, often genericised trademarks, is not new, as anyone who has hoovered the rug will tell you!) In some cases, we use the same word for the action (to design) as we do for the product (a design) and, especially in the case of design, this can cause trouble because it becomes very easy to ask someone for the product when what you want is the process.

Now, I realise that I do enjoy linguistic shenanigans (anyone who plays with which syllable to stress when saying interstices is spending too much time thinking about language) but this is not some syntactic mumbo jumbo, this is a genuine concern. If I ask a student to submit a design for their program, then I am usually assuming that the artefact submitted will be the product of the design process. However, I have to realise that a student must understand what the design process actually is in order for my instruction (give me a design) to be mapped into the correct action (undertake the design process). We’ve collected a lot of first-year student reflections on design and it is becoming increasingly apparent that there is not a clear link between the verb and noun forms of this very simple word. We can now start to understand why a student would feel frustrated if, when asked for a design, they submit what is effectively a re-writing of their final written program on a separate document with some arrows and we turn around and tell them that “this is not a design”. Well, what did we want? The student has given us a document with stuff on it and the word ‘design’ at the top – what did we expect?

The same is, more subtly, true of the word program. After all the practise of programming is the production of programs (and the consumption and elimination of problems but that’s another post). Hence, when I ask a student for a program, or for a solution, I am often not explicitly placing the written instructions into a form that clearly elucidates the process and, as a result, I may miss important constructive steps that could assist the student in understanding and applying the process.

Let’s face it, if you don’t know what you’re doing, or don’t understand that there is a process to follow (the verb form), then any instructions I give you “Make sure you use diagrams”, “clearly label your variables”, “use UML” are going to be perceived in a way that is grounded in the final product, not the steps along the way. If I can use neo-Piagetian terminology briefly, then we’re looking at the magical thinking that we’d normally associate with the pre-operational stage. Not only is the knowledge not sinking in but we will engender a cargo-cult like inclusion of features that are found in the artefact but have no connection back to the process at all. We have potentially reached the unpleasant point where students now think that we are deliberately, or unfairly, ignoring the work that they provided in direct accordance with our instructions!

Anyone who has ever looked at a design with the steady sinking feeling that comes from reading poorly translated programming language, marked with superfluous arrows and dogged, yet unnecessary, underlining of the obvious, will probably be feeling a pang of empathy at the moment.

So what to do? How do we address this problem? The first step is to remember how fiendishly ambiguous language actually is (if English were easy, we wouldn’t need constrained and artificial programming languages to unambiguously assign meaning for computers) and be precise about the separation between the process and the product. The design process, which we provide guidance and steps for, will produce a design document. We are luckier in programming because while you can program and produce a program, you cannot produce a programming! In this case, the clarification is that you have assigned a programming task in order to produce a program. In our heads, we are always clear about what we mean but it is still amazing how often we can resort to asking for a product that is the final stage of a long and difficult process, which we are intending to teach, without realising that we are describing the desirable characteristics of the end point without considering the road that must be travelled!

On reviewing my own teaching, I’m intending to add more process-based instructions, on the grounds that encouraging a certain behaviour in the production process is more likely to lead to a successful product, than specifying an end product and hoping that the path taken is the ‘right’ one. This isn’t exactly rocket science, it’s well established in how we should be constructing these activities, but it does require the educator to keep a clear head on whether we are discussing the product or process.

When a student has established enough understanding, and hopefully all will by the end of the process, then I can ease back on these linguistic scaffolds and expect a little more “this means that” in their everyday activity, but at the start of the educational process, it is probably better if I always try consider how I specify these potentially ambiguous noun/verb pairs. After all, if a student could pick this up by osmosis or plain exposure to the final product (or even by neurolinguistic programming through the mere mention of the name of the artefact) then I would be thoroughly unnecessary as an educator!

I strive to reduce ambiguity and this requires me to think, very carefully, about how my words are read by students who are not even in the foothills of mastery. Reorienting my own thinking to clearly separate product from process, and labelling and treating each clearly and separately, is an important reminder to me of how easy it is to confuse students.

Learner Pull and Educator Push

Posted: November 21, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , | Leave a comment

We were discussing some of the strategic investments that might underpin my University’s progress for the next 5 years (all very hand wavy as we don’t yet have the confirmed strategy for the next 5 years) and we ended up discussing Learner Push and Educator Pull – in the context of MOOCs, unsurprisingly.

We know that if all we do is push content to people then we haven’t really undertaken any of the learning experience construction that we’re supposed to. If we expect students to mysteriously know what they need and then pull it all towards them, then we’re assuming that students are automatically self-educating and this is, fairly obviously, not universally true or there would have been no need for educational institutions for… hundreds of thousands of years.

What we actually have is a combination of push and pull from both sides, maintaining the right tension if you will, and it’s something that we have to think about the moment that we talk about any kind of information storage system. A library is full of information but you have to know what you’re looking for, where to find out and you have to want to find it! I’ve discussed on other blogs my concerns about the disconnected nature of MOOCs and the possibility of students “cherry picking” courses that are of interest to them but lead nowhere in terms of the construction of a professional level of knowledge.

Mark Guzdial recently responded to a comment of mine to remind me of the Gates Foundation initiative to set up eight foundation courses based on MOOCs but that’s a foundation level focus – how do we get from there to fourth year engineers or computer scientists? Part of the job of the educator is to construct an environment where the students not only want the knowledge but they want, and here’s the tricky bit, the right knowledge. So rather than forcing content down the student’s throat (the incorrect assumption of educator push, in my opinion) we are creating an environment that inspires, guides and excites – and pushing that.

I know that my students have vast amounts of passion and energy – the problem is getting it directed in the right way!

It’s great to be talking about some of these philosophical issues as we look forward over the next 5-10 years because, of course, by itself the IT won’t fix any of our problems unless we use it correctly. As an Associate Dean (IT) and a former systems administrator, I know that spending money on IT is easy but it’s always very easy to spend a lot of money and make no progress. Good, solid, principles help a lot and, while we have a lot of things to sort out, it’s going to be interesting to see how things develop, especially with the concept of the MOOC floating above us.

Unearthing the Community: A Surprisingly Rapid Result

Posted: November 20, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , | 2 Comments

I am thinking of a number between 1 and 100…

Next Monday I am co-hosting the first Adelaide Computing Education Conventicle, an offshoot of the very successful program in the Eastern states which encourages the presentation of work that has gone to conferences, or is about to go, and to provide a forum for conversations and panel discussions on Computing Education. The term ‘conventicle’ refers to “A secret or unlawful religious meeting, typically of people with nonconformist views” and stems from the initial discussions in Melbourne and Sydney, back when Computing Education was not perhaps as accepted as it is now. The name is retained for gentle amusement and a linkage to previous events. To quote my own web page on this:

The Conventicle is a one-day conference about all aspects of teaching computing in higher education, in its practical and theoretical aspects, which includes computer science, information systems, information technology, and branches of both mathematics and statistics. The Conventicle is free and open to all who wish to attend. The format will consist of presentations, discussion forums and opportunities to network over lunch, and morning and afternoon tea.

The Conventicles have a long history in other states, allowing a discussion forum for how we teach, why we teach, what we can do better and provide us with an opportunity to share our knowledge at a local level without having to travel to conferences or subscribe to an every growing set of journals.

One of my ALTA colleagues set his goal as restarting the conventicles where they had stopped and starting them where they had never been and, combining this with my goal of spreading the word on CSE, we decided to work together and host the informal one-day event. The Australian gravity well is deep and powerful: few of my colleagues get to go to the larger educational conferences and being able to re-present some key papers, especially when the original presenters can be there, is fantastic. We’re very lucky to have two interstate visitors. Simon, my ALTA colleague, is presenting some of his most recent work, and Raymond Lister, from UTS, is presenting a very interesting paper that I saw him present at ICER. When he mentioned that he might be able to come, I didn’t wast much time trying to encourage him… and ask him if he’d mind presenting a paper. It appears that I’m learning how to run a conference.

The other good news is that we have a full program! It turns out that many people are itching to talk about their latest projects, their successes, recent papers and about the things that challenge so many of us. I still have space for a lot more people to attend and, with any luck, by this time tomorrow I’ll have the program nailed down. If you’re in the neighbourhood, please check out the web page and let me know if you can come.

I hope to see at least some of the following come out of the First Adelaide Computing Education Conventicle:

  1. Raised awareness of Computing Education across my faculty and University.
  2. Raised awareness of how many people are already doing research in this!
  3. An opportunity for the local community to get together and make connections.
  4. Some good discussion with no actual blows being landed. 🙂

In the longer term, I’d love to see joint papers, grant applications and all those good things that help us to tick our various boxes. Of course, being me, I also want to learn more, to help other people to learn more (even if it’s just by hosting) and get some benefit for all of our students.

There’s enough time to get it all organised, which is great, but I’ll have a busy Monday next week!

 

By George, I Think She’s Got I… No, She Hasn’t: Threshold Concepts and Oscillation

Posted: November 19, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , | 4 Comments

“Eliza, where the devil are my slippers?” marks the end of the musical “My Fair Lady” and, in many ways, sets the stage for a new set of developments in the life of the former-flowergirl Eliza Doolittle and the curmudgeonly and misogynistic Henry Higgins. (A far more romantic end in many ways than the original Shaw but, as one the producers noted, the public were happier with the upbeat ending. In fact, one of the producers observed to Shaw that “Your ending is damnable; you ought to be shot.” O tempora, o mores!) Much of this play/film, about the re-education of a Cockney flower girl into the speech patterns and behaviours of the wealthy English upper class, focused on Eliza’s transition and her ability to apply all of the knowledge that Higgins and Pickering sought to impart. Eliza, for dramatic value, had grand successes and major set-backs. Having mastered some fundamental phonemes, her exuberant nature was her undoing at the racetrack. Convinced that she had now absorbed the speech patterns so well that Cockney was now behind her, the entrance of her father immediately undid everything and brought her back to her birth speech.

Rex Harrison and Julie Andrews from the Broadway production. The film version featured Audrey Hepburn as the studio wanted a ‘name’. Not only did Hepburn have to be dubbed for singing but Julie Andrews went on to take the Oscar for Mary Poppins in the same year. Ouch.

This is a play, so let’s not read too much into the educational presentation, but as an introduction to the phenomenon of oscillation, it’s quite a nice one. Threshold concept theory holds that there are certain concepts in every area of knowledge that are fundamentally challenging to the learner. These concepts are alien or counter-intutitive, they link together a great many concepts from within the area or subarea, but upon reaching a level of understanding of the concept, it transforms the way that we think from that time on. These threshold concepts mark a boundary between areas and ways of thinking: truly mastering a threshold concept will open up new vistas and change forever how we regard that area of knowledge. The problem is that the progress that a learner makes towards mastering the threshold concept is not guaranteed to be a smooth path: this is a road towards a challenge and it is often a hard road to travel. When a learner starts trying to master the new concept, they enter what is referred to as the liminal state and it is during this state that they can experience oscillation and risk developing fragile knowledge.

Oscillation is the movement backwards and forwards in terms of developing and understanding components of the concept, and is frustrating to both learner and educator as the learner appears to be ‘getting it’ then moves backwards. An obvious misinterpretation of this is that the learner has “stopped trying” or is either “’lazy” or “stupid”, when in fact this reflects the intrinsic cognitive difficulty in the underlying concept. Fragile knowledge is where the learner has some notions of how to solve problems but cannot construct a clean solution, which may allow excellent participation in certain activities and assessments but not others. Along with these, it’s important to remember that  sometimes learners will resort to mimicry: turning around what the learner has already seen and presenting it back to us, again giving a false impression of understanding.

We have, I suspect, all faced the student who appears to have (after much effort) achieved the understanding that we both sought and, as we probe their knowledge, we only see confirmation of mastery until, oh no, suddenly it all falls apart and we realise that what we were seeing was built upon fragile knowledge and couldn’t really function as a foundation for all of the concepts, or that we had unwittingly provided an environment where the student could parrot our own wisdom back to us and give us the impression of understanding. We must, however, remember how frustrating it must be for the student to suddenly discover that all of the progress that they thought they had made was not actually sustainable or all that solid. Taking an accusatory or judgemental stance at this point is really not going to help anyone but, if we accept that threshold concepts exist and provide this level of challenge, we have a way to think about these kinds of setbacks that say “We’re in the liminal state. This is just what happens.”

One of the reasons that I think threshold concept theory resonates with me so deeply is that gives me a basis for a quiet stoicism in the face of these kinds of setbacks. You probably shouldn’t set out on a cross-country trip and expect to see no red lights or roadworks, or to never get lost taking a turn off to go and buy lunch, because you will be deeply unhappy and frustrated by the first reversal of fortune. You also would not build in enough time to reach your destination! (One time I was driving about 6 hours across the US to see my family and the GPS took me the ‘fast’ way, which turned out to be DC to the Tennessee/VA border via West Virginia. Fortunately my family love me, so showing up 30 minutes late wasn’t a big deal, but the fault was mine because I had not allowed enough time to handle 30-60 minutes of delay, and that’s pretty much the amount of delay I get over time on that trip.) Sometimes things will take longer because these concepts are hard to grasp and we are on uncertain ground. This isn’t about learning 2×2, 2×3 and so on, this is going to transform the way that someone thinks. That makes it important.

These ideas have huge implications on everything we do with students that have deadlines or any form of time restriction. If these concepts are so counter-intutitive and challenging, then we would expect to see variation in how quickly people pick things up. Maybe that one-hour lecture slot isn’t enough? This is where the new materials and media that we have really start to look useful. Suddenly, your lecture recordings give people the chance to think and digest, rolling forwards and backwards to get a really good grip. Scaffolded on-line materials, with increasing conceptual difficulty that allows the student to stage their self-testing and establish that they are thinking along the right lines, become much more important and are worth a lot more invested time.

Accepting threshold concept theory, however, may be a threshold concept itself – it may be a while before we see really widespread acceptance of this simple idea.

Wrapping up Grand Challenges

Posted: November 18, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , , , | Leave a comment

We had the final ‘farewell’ function for the end of my Grand Challenges course on Friday. While I would normally see most of these students again, as this is a first year course, one of them was a US exchange student who is flying home this morning to return to his own college system. I wanted to bring everyone together, in an informal setting, to say well done and farewell. It has been a remarkable semester. For me, now, digging through the student comments and feedback will drive a lot of my thinking for the next version of the course and the comments are very, very interesting. Students reflecting on the fact that they didn’t quite understand why they learned about the grand challenges in the first place, until we were knee deep in questionable ethics and the misapplication of Science, and then *bang* it all settled into place. Yes, this is what I intended but, frankly, it’s a little bit of a high risk strategy to construct scaffolding in that way and I had to carefully monitor the group dynamics, as well as making sure that the group had enough elements in it that we could achieve a good environment in which to reflect and develop. I, by myself, cannot be a full member of the group and I’m always going to be the outsider because, well, I have to be in order to function in the course coordinator and marker role.

Next year, we already have a lot of interest in the new course and this is very exciting. I’m not sure how many will roll up but I do know that I cannot handle a group larger than 8 with the current approach – hence, as I’ve said before, I now need to take all of the comments and work on scaling it up. Sitting around the table on Friday night, talking to all of the students, it really sank in that we (as a group) had achieved something pretty special. I couldn’t have done it without them and (I suspect) a lot of them weren’t quite ready to do it without me. What I saw around the table was passion, confidence, enthusiasm and curiosity. There was also some well-deserved pride when the final poster prints were handed out. I had their first projects professionally printed on Tyvek, a plastic material that is waterproof, hard to tear and really tough, so that their posters will go anywhere and hang up, without risking becoming sad and daggy old faded relics with tears and dog ears. The posters were the result of 6 weeks of work, hence some respect was due to their construction.

I’m not a very reserved person, which will come as no surprise to any of you, and people generally know what I’m feeling (with the usual caveat that I can appear delighted by the questionable musical practices of children and fascinated in meetings). My students will therefore know that I am pleased by what they have achieved and what, by their enthusiasm and willingness to go with a non-traditional structure, we have managed to achieve together. Was it perfect? No. I need to cater for students who are in transition more and remember that just because students can perform well academically, it does not magically grant them the associated maturity or ability to handle the unforeseen. It could certainly have been better organised and that was really down to the experimental nature of the course combined with my schedule. I was too busy, sometimes, to be as forward looking as I should have been (I was looking weeks out, rather than months). That will not happen next year. What’s really interesting is what my colleagues assume about these students. “Oh, they’re smart so they must have done all this maths or love maths or something.” No, they don’t. They come in with the usual range of courses you’d expect from students and have the usual range of likes and dislikes. They are, in a nutshell, students who happen to have worked out how to perform well under assessment. As it turns out, a GPA or ATAR (SAT) mark does not summarise a student, nor does achieving the same grade make you the same person. Shocking, I know.

But, snark aside, what a great experience and, from early indications, I am pretty confident that some of these students now have a completely different set of lenses through which to view the world. Now, of course, it is up to them. You might think that my posturing on an apolitical stance is just that, a posturing facade, but I am deadly serious about not imposing my political beliefs on my students. Yes, I firmly believe that there are a set of ethical standards that people in my discipline (Computer Science) and my calling (Education) should adhere to, but how you vote? None of my business. Next year, I hope to bring in more people from industry, more entrepreneurs, possibly even some more ‘challenging’ viewpoints. The world is complicated and the intellectual challenges are many. Me training students in dogma does nothing. Me training students in how they can think for themselves and then genuinely standing back to say “That was the toolkit, it’s up to you what you build” will truly test me and them.

Far too many times I’ve held forth on silly little points where I was wrong, or misinterpreting, and it didn’t help anything. I’ve always learned more from discussion than argument, and from informed disagreement rather than blind agreement. That’s the fine print on the PhD, as I read it, “be prepared to be wrong and then work out how to be right.”

If I were ever to work myself almost to collapse again, taking on too much, striving to develop an entirely new course for a new type of student that we haven’t really catered to before, while doing everything else – I would hope that at the end of the year, I could look back on something like Grand Challenges and nod, with satisfaction, because it worked. I’m looking forward to bouncing ideas off the course members over the next 6 months to get their feedback on the new direction, possibly using these students as mentors and tutors (good idea, MH) to help me run the course and to keep building the community. That’s what it was always about, after all. Yes, it was a course for students who could handle the academics but it was always about the biggest Grand Challenge of them all: getting people to work together to solve problems.

Turn on the news and you’ll see lot of problems at the moment. Running up to (yet another) end of the world, we are once again taking the crazy pills and, bluntly, it scares me. We have a lot of problems to solve and that will take people, working together, sharing, talking and using available resources to try and deal with things that could potentially destroy our species. If you have the opportunity to tun any kind of program that could assist with this – problem solving, community building, team formation, outreach to other schools, or whatever – please consider doing so. I’ll tell you, honestly, it’s one of the most rewarding things that I’ve ever done and I’ve been privileged to be able to do a lot of cool things.

First Class Service from a Classless Medium

Posted: November 17, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , | 3 Comments

The summary of today’s post is that I’m not a fan of curve grading. If you’ve read enough from me about this before, feel free to skip this post. 🙂 Now, I should note that a lot of what is in here is based on my observations of Facebook from the outside – there may be technical stuff that I’m missing because I haven’t had the time to dig down. Clarifications and corrections are welcome.

If you read yesterday’s post, you’ll see a lot of discussion about how people use (or misuse) Facebook but one thing that is becomingly increasingly apparent is that Facebook is trying to do a very difficult thing: offer different tiers of service on a system that is fundamentally not tiered. If you’ve been on a plane recently, you’ll know that you all get to the destination at the same time, regardless of how much you paid. The fundamental service of the airlines, getting you from A to B in a giant metal tube, is such that passengers on the same plane will all have the same experience in terms of travel time. This is, of course, why the differentiators in service revolve around the overall pleasure and comfort of the experience. Flying long-haul economy is a transport miracle but, that aside, it’s not a very pleasant experience. The seats are cramped, you’ll get at least a stiff neck and most likely ballooned legs from being jammed into the seated position for hours. Up in Premium, Business and First, passengers are stretching out, getting more food, have a higher ratio of staff to passenger and enjoy more access to much nicer toilets. But where did all of that extra space and service come from? Here’s a hint: the next time you’re in economy and wonder why you can’t stretch your legs, it’s because someone is paying more to enjoy some of that space up the front of the plane.

Facebook is, at its core, really simple. You create an account. People who are your ‘friends’ decide to monitor the things that you type. You monitor theirs. If you have an interest in a group or page, you’ll ask to see their updates as well. Updates can be displayed in date/time order (newest first) or by level of interest (how many people are talking about it). Well, it was that simple. Now, as you will know, there is an ongoing move towards restricting the degree to which information naturally flows from one person to another. Now, my friends will see most of my posts (unless they take some steps to change the way that they view me) and if I happen to watch a page from a business, the business needs to pay some money to FB to ensure that all of their followers receive all of their updates.

Facebook, in its simplest form, sends updates to interested people but, as the Facebook people have worked out, this does not allow you to easily impose a premium service over the top. You have a free water fountain that serves chilled water. Why would you buy a bottle of water from the guy standing next to the fountain? In this case, the guy owns the fountain and he decides that sometimes it works and sometimes it doesn’t. Want to guarantee that you’ll never go thirsty? Better buy my water.

I wouldn’t have a problem with any of this if the base service was kept at a reasonable standard. I’m looking to shift my frequent flyer status for airlines to one of Air New Zealand or Singapore because, in all my experiences, their economy experience is absolutely fine. Plane goes from A to B. Seat is comfortable enough for 15 hours. Staff are nice. Food is fine. On my usual carrier, which shall remain nameless, it takes me longer to recover from the cramped conditions of their economy and aggravates my surgically altered left knee. (For the record, I’m 5’11” and about 190lbs so I should fit into a seat without too much fuss.) Having flown premium and business on nameless airways, I can tell you that it’s fantastic but we have flipped from a below acceptable standard to above acceptable standard (in fact, the food in Business is excessive and gluttonous, in my opinion) without ever having settled on the minimum standard of acceptability for what is, ultimately, all of us flying together in the same metal tube.

Facebook used to have a base, acceptable service, that revolved around reliably showing me things from my friends. Where do sponsored links fit into this? They don’t, unless FB can inject unasked for content into my stream when someone pays them to. So, now, I am reading things from people who are not my friends, that I cannot control, because someone else is paying for it. Of course, the kicker on this is ‘why would you pay FB to do this?’ and the answer is ‘Only if FB would not guarantee universal delivery if you didn’t’. Now, people being people, if FB said “Hey, commercial accounts have to pay this but private individuals wouldn’t” then there would be a surprisingly large number of ‘private individuals’ trying to sell you stuff. So, because of human nature, when FB cuts down on people seeing everything that you post (requiring sponsorship to push ideas or to guarantee universal subscription) this is going to apply pretty much across the board.

Now, I am not paying for Facebook but it is becomingly apparent that I am being sold by Facebook because all of the downgrades that I am seeing are intended to provide a reason for people to pay to reach me as a consumer. My problem is, free or not, the way that Facebook is altering the service to make me as a product more attractive to a consumer is affecting my experience. They are forcing a vast majority of people into a second-class experience in order to be able to sell the default set-up as a first-class experience. There always will be some kind of load filtering on a system like this but this one, so blatantly and explicitly linked to selling reach, really makes you wonder what their long term plans are for their community.

Now, you’ll either be agreeing with me or disagreeing with me by now, as if you stopped reading out of boredom you won’t see this! So let me give you a first/second-class analogy from education: curve grading. If I have a fixed number of A slots in my class then, by extension, anyone extra who would have got an A MUST get a B in order to be able to grant the A’s to other people. Yes, we’ve sorted them by degree of A but, under our original terms, the student has done A-level work, we’re just not giving it to him or her because someone else is being prioritised up and, to preserve the experience of the A people, someone has to get Bs. More insidiously, somebody has to fail. We’ve now gone further than the airline or Facebook examples, because now the people in Business can require that someone be kicked off the plane. You don’t click on enough sponsored links, your login is rescinded and you have to leave Facebook. You may not care about air travel and, let’s be honest, it’s a giant privilege in any way you look at it. You might think “Hey, FB isn’t my life and it’s not like I’m paying for it” and that’s very true.

But carving out a new ‘premium’ experience that is the old ‘fair and general’ experience and doing so by forcing other people into a second-class experience is a pretty lousy way to treat people and, in my opinion, it’s worse when those people are your students and you make them competitive through an artificial resource scarcity, based around some mistaken notion that this is a reasonable thing to do. You don’t have to think hard to come up with examples that quickly demonstrate how broken this kind of system is. Facebook bugs me but it won’t cause me too much grief if it goes away tomorrow. A student’s academic progress, GPA and their own confidence? All too important to put into an artificially imposed additional classification scheme that forces classes where they may not belong.

What Do You Mean… “Like”?

Posted: November 16, 2012 | Author: | Filed under: Education, Opinion | Tags: , , , , , , , | 9 Comments

I was alerted to a strange game the other day. Go to Mitt Romney’s Facebook page, note the number of ‘likes’ and then come back later to see if the number had gone up or down. As it turns out, the number of Facebookers who ‘like’ the former Presidential Candidate’s Facebook page is dropping at a noticeable but steady rate. My estimates are, if this drop is maintained and it is linear, it will be about 1666 days until there are zero people liking the page. (Estimates vary, but the current rate of loss is somewhere around 11 likes a minute. You can watch it here in real time.) I mention this not to add to Mr Romney’s woes, because he is already understandably not happy that he lost the election, although you may disagree with the reasoning in the linked article. I mention this because it identifies how nebulous our association is with the term and the concept of ‘like’.

If this is your closest friend, you might need to catch up on this thing that we call ‘Facebook’.

For those who have recently returned from 7 years of bonding with a volleyball in the Pacific, Facebook does not allow you to ‘dislike’ things, it only allows you to comment or hit the ‘like’ button (or hide the comment or post but that’s a separate thought). What does it mean then to not click the ‘like’ button or to comment? Thank you, Facebook, for presenting us with yet another false dichotomy and for giving us such a large example on Mr Romney’s page. Before the election, millions of people liked Mr Romney’s page which, one can only imaging, meant that they were showing him support and saying “Go, Mitt!” Now that, in a completely different way, the message “Go, Mitt” has been communicated, it appears that, at a time when an unsuccessful candidate would need the most support, the followers are leaving. Now, this is important because, as I understand it, to stop liking something you have to take the active step of clicking on something – it doesn’t just expire in a short timeframe. People are actively choosing to remove their liking of Mr Romney’s page.

Why?

Well, there’s a lot of speculation about this, including the notion that some of the initial surge of followers came from buying friends by bringing in other accounts that are used by non-people but this still doesn’t explain where the unlikes are coming from because, after all, a Justin Bieber Slashfic Spambot is nothing if not loyal in its mechanically allocated trust. What is probably happening here is that the social media front ends were being used explicitly as part of a campaign to see Mr Romney elected President and, understandably, the accounts are now seeing much less use and, fickle as the real Internet is, you’re only as good as your last post or as hot as your posting frequency. The staffer or group of staffers that were paid to do this have now lost their jobs and the account is heading towards the account graveyard. (The saddest thing about any competition like this is that someone, somewhere, who has been doing a good job may still lose their job because the public didn’t support their candidate. I try to remember that before I overly celebrate either victory or defeat, although I don’t always succeed.)

What concerns me are the people who liked this Facebook page, legitimately and as real people, and have now turned around and deliked it, because this can easily be seen as a punitive action. It has no real impact on Mr Romney in any sense but it does make him look increasingly unpopular and, really, it achieves absolutely nothing. What does ‘like’ mean in this context? I support you until you fail me? I support you because you might be President and I have some strange mental model that your Secretary of State will be picked randomly from your Facebook followers?

To me, honestly, a lot of this looks like spite. After all, what does it hurt to remain a liker of a dead page? It doesn’t, unless your aim is to send a message. However, I think that Mr Romney probably already knows that he didn’t get elected to the highest office his country can offer – but I’m sure that when he becomes aware of all of the people fleeing his page, it will really neatly reinforce how he could have improved his campaign.

Oh, wait, that’s my point! The vocabulary of like/delike (recall that there is no dislike option) is fundamentally useless because of its confused binary nature. Does no ‘like’ mean ‘dislike’,’meh’,’sort of like’,’maybe in a dark room’ or ‘I missed this’? Does ‘like’ mean ‘yay!’, ‘hugs!’, ‘i want to smell your hair’ or ‘*gritted teeth at your good fortune*’? Or does it just mean ‘like’? We have no idea unless someone comments and, given that we have the easy out of ‘like’, many people won’t comment because they have the deceptively communicative nature of the flawed channel of ‘like’!

Like most Universities, we have a survey that we run on students at the end of courses to find out how they felt about the course, what their experience was. Regrettably, a lot of the time, what you end up measuring was how much a student liked you. It’s on a 7 point Likert scale but, and many students don’t realise this, the middle point is not ‘non-committed to like/dislike’, it counts as ‘not like’. Hence if you get 7/7 from everyone for something and get one 4/7, you no longer have 100% broad agreement regarding that point. Because there is confusion about what this means (and there is a not applicable that is separate to the scale), students who don’t care about anything tend to write down the middle and end up counting as a vote against. Is this fair? Well, is that the question? Let me ask a different one – was it what the student intended? Maybe/maybe not. As it stands, the numbers themselves are not very much use as they tell you what people feel but not what they’re thinking. The comments that also come on the same form are far more informative than the numbers. Much as with Facebook, there is confusion over like/dislike, but the comments are always far more useful in making improvements and finding out what people really think.

I feel (to my own surprise) some empathy for Mr Romney at the moment because there are hundreds, if not thousands, of people a day sending him a message that is utterly and totally confusing, as well as being fundamentally hypocritical. Ok, yes, he might not care to know what every American thought he got wrong, the Internet can be challenging that way, but ‘deliking’ him is not actually achieving anything except covering your tracks.

What did any of these people, who have now left, actually mean by ‘like’?

Winding up 2012: Dear Students…

Posted: November 15, 2012 | Author: | Filed under: Education, Opinion | Tags: , , , , , , , , , , , , | Leave a comment

Dear Students,

After this week I will not see many of you until February of next year and, some of you, I may not see again because you’ll go on to do other things. This is the time of the year when I reflect upon what I have achieved in terms of contributing to the knowledge and skills of my students and how I can do it better. I have to start from the presumption that I can always improve upon what have I done but, even without that, accepting that every year will bring a different group, with different needs, forces me to think about the core of my teaching – as opposed to what actually came out in the teaching activities. What I always want to achieve is to help you develop yourselves. I can’t change you but I can help you change. If you know more, understand more or can do more at the end of the year, then I’m happy. If you go on to help other people, then I’m ecstatic!

Many people throughout your lives will tell you big, shiny success stories and expect you to take a certain path because there’s a big brass ring at the end. I have walked that path and have known success but, if we are being honest, success is not the same as happiness. Throughout the year we have discussed many things, scholarly and secular, but we have rarely had the time or the opportunity to talk about some of the most important things in life: the reasons why we do things and, ultimately, how it will make us feel. But you shouldn’t be listening to me because of who I am or how you think of me, I’m just another voice from our species and I have one of the many opinions. My friends will (I hope) tell you that I am mostly a good man, with some occasional moments of selfishness and stupidity. You should realise that almost everyone is like this. It would be impossible for us to live as we do, where we do, were this not so. The majority of people are good, most of the time, with occasional moments of stupidity. What that means, of course, is that we have a terrific amount of force to act against those who are always stupid or unpleasant – the silent majority is powerful.

Firstly, let me tell you how much I love our magnificent, terrible and bizarre species. We are terrible and beautiful. We are capable of acts of tremendous selflessness and kindness, yet sometimes we taint it with greed, selfishness and cruelty. We are driven by so many things and, the more I read, the more it becomes apparent that who we are, as individuals, is as much about the world around us, our families and friends, our education and our overall exposure to reality, as it is about ourselves. I can think of several points in my life where the intervention of other people has held me back from a terrible and destructive course, explicit examples of changing direction, but there are so many examples that speak of casual intervention: a smile on a day when I needed one, someone holding the door, being let into traffic after waiting forever.

To try and distill this species, into the “pull yourself up by your bootstrap” myths of Horatio Alger or to claim it is all emptiness and cynicism, is to sell us, and you, short. Fairy tales are conveniently small fictions, now separated from their original cautionary endings, that sell you a “happy ending” as a bill of goods, as if all you have to do is to kiss the frog, find the right name or have the right shoe size.

Nothing is that easy. If it is for you then, sadly, experience tells us that you will not really appreciate it that much. This is not a rationale for suffering but an observation of the bad behaviour that seems to come at certain levels of privilege. Be in no doubt, if you leave with a degree then you are privileged. This is not a matter of guilt or a burden, it’s just a fact. Some of you will never appreciate how lucky you were to go to University at a time of peace in a prosperous country because you do not quite realise how fortunate you were. You are no more or less entitled to be educated than the next person and it is pure accident that determines who enters school in a safe, highly educated, country, rather than trying to learn under gunfire in a cramped and broken classroom where you might be lucky to get to Year 6 before forced to go and work to keep your family alive. Some of you have made it through wars and fought your way to restart your education, surviving that and striving for more. Some of you represent minorities, first-in-family or face terrible ordeals that your peers will never quite understand. Many of you, facing no other impediment other than ignorance of a certain area, strive for more and to achieve a greater understanding. I salute all of you for your efforts, especially where you have reached out to help your peers. But why are you doing this?

We often fail to ask ourselves ‘why?’ “Why are you doing this degree?” “Why are you looking for this job?” “Why are you doing this?”

You will often be encouraged to believe that questions like “Am I happy?” or “Should I be doing this?” are somehow not appropriate questions – indicative of some sort of laziness when you should be seeking jobs and working harder, every single day. So, what are your plans? If your answer is “Get a job”, then which job are you looking for? If the answer to that is “a programming job”, then what kind of programming job? If you don’t know what you really want to do, then how will you know when you’ve found it? How can you search for something better? How will you say no to something that will make you miserable? What do you need to live and what do you need to make you happy? Can you combine them?  Many of you will have dependents and you will have to take the work that is offered, when it is offered. If you do have some freedom of movement now then I encourage you to make the best use of it so that, when people do depend upon you, you can support them with little or no resentment. Remember that rarely do the people we support ask for our help for any other reason than they need help. I always have to remember that when a student asks me a ‘silly’ question. It’s not about me – they just need my help and probably don’t yet realise what the question sounds like.

What makes you happy? Can you make it a job? Are you happy now? Do you actually want this degree? Why? Most students start University with no clear plan or understanding of why they’re doing it. Now, most students then end up finishing and having some idea of what they’re doing – and a Uni degree is a great thing to have when we teach it properly – but leaving after 3-5 years with a degree and no idea of direction means that finding something that you want to do is going to be a crap shoot. This must be tempered by the realities of your life because this is no fairytale.  You will give 5% of your time to some people and they will be so grateful in return that you will be embarrassed. You will try to give 200% to other people and they will only demand more. You will not necessarily know in advance which way this will go. Those of you have choice must remember that there are many, many more who don’t. Again, this is not about guilt but about perspective and valuing what you have, and what you can do.

I am, unashamedly, focused on actions taken for the good of us all: our community, our society and our home, which is far more than just a place for humans. I have spent time at a very low ebb over the years: depressed, deep in debt, terrible job or unemployed, living on almost no food for weeks, giving away my own books and CDs as gifts to not stand out at social gatherings, washing my clothes in the bathroom sinks at work to hide the fact that I couldn’t afford laundry powder or new clothes. I hope that none of this ever happens to you but you should be aware that this is happening, day after day, to people everywhere. Many of these people did not go to Uni, did not finish school, may not have basic literacy. How do you expect them to pull themselves up by their bootstraps when they have no boots and someone is standing on their toes (to quote Dr King).

I do not want to encourage you towards any movement, political, secular, religious or otherwise. It is none of my business what kind of “-ist” you become, if any, as long as you do so fairly, ethically and with respect and an appreciation of who you are and the people around you. I find myself constantly challenged to live up to my own beliefs and my ideals. Sometimes I do, sometimes I wish I had tried harder. That’s just how it is, for almost all of us.

My sincere wishes for a beautiful and happy future,

Nick.

Official plans for this blog: 2012/2013

Posted: November 14, 2012 | Author: | Filed under: Education | Tags: , , , , , , | 1 Comment

I’ve been thinking about how I’m going to go forward after my year long commitment to daily blog updates and I have settled on the decision that the 1st of January, 2013 (Yes, yes, it originally said 2012), at 4:00am Adelaide time, will mark the last of the ‘daily’ posting commitments. From that point on, I will post as things interest me and when I have the time to deliver a good, sound and useful post. I have been concerned for some time that the quality has been sacrificed to get something out and this is not what I set out to do. Two days I sat down to write the blog and stared at the screen for 15 minutes before I sighed, gave up and decided to come back the next day. I then went on, the next day, to post a heap of stuff because I was refreshed. But, frankly, I’m busy enough without adding too many more hoops, bells and whistles to my life. (Unless it’s the circus from Madagascar 3, in which case sign me up!)

Polka dot, polka dot, polka dot, afro!

I do not, for a single moment, regret the commitment because now I know I can do it and it has definitely transformed the way I think about many important things. However, this structure has served its purpose and, once I’ve completed the commitment, I’ll be happy to take a more freeform approach. Now, I’m not saying that I will post more or less, what I am saying is that I will post with less regularity from January 1st and, more importantly, I will have the ability to take some time off if I need to concentrate on projects or work that may then lead to some far more interesting blog posts.

I will still be posting on the daily cycle until then and I thank everyone for continuing to read!

Ethics and Opinion: Please Stop Confusing My Students

Posted: November 14, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , | Leave a comment

One of the sadly rather expected side benefits of the recent re-election of President Obama has been the predictable outpouring of racist sentiment. Of course, to listen to the people uttering racial slurs and unpleasant requests, they are not actually racists, they are just expressing their opinion. You know?

They’re just sayin’.

A woman is currently being investigated by the Secret Service for Tweeting a heavily charged racial epithet against the President, wrapped up in a paraphrased death threat, and appears puzzled about all of the fuss. After all, it’s just what she thinks and she’s not a racist. Australian former cricketer Greg Ritchie recently uttered some serious racial slurs that are highly inflammatory towards South Africans and can’t see what the big deal is either. He also managed to get in a joke about Muslims. When asked, however, Ritchie had this to say:

“If they take offence that’s their choice.”

His joke, involving Muslims, is in his own words “just a little humourous joke to indicate that they’re not my favourite people of my choice.” Hey, Greg, guess what, when you’re trying to defend yourself against charges of discrimination, perhaps it’s best to do so in a way that is not actually discriminatory? Of course, we’ve been tolerating Ritchie’s antics for years, so it’s not surprising that he is now confused that we don’t find him funny. He, in blackface as pseudo-Indian Mahatma Coate, was a regular on the Australian Rules Football sports variety show “The Footy Show” for years. And, thus we crawl, inexorably, towards my point.

If you’re opinion is actually racism, then it’s a racist opinion. I can completely understand why people don’t want to be labelled as racists because we all know that’s bad but, and here’s the tricky thing, racists are people who believe and say racist things or act in a manner than discriminates against people based on their race. Calling someone a racial epithet because of the race that they belong to counts here and, before we get all ‘classification theory’ about this, there is a world of difference between any classifications of ethnicity that are scientific in nature and slurs. There is also a great deal of difference in how we use this information. The moment that you start saying things like “they’re not my favourite people of choice”, you are saying that you don’t like an entire group that is defined by a given characteristic and, wow, it’s not hard to see where that leads. (Now, no doubt, there is someone who is itching to leap and tell me that ‘aha – Muslims are not a race’. Spare me the sophistry, especially where the Muslims that appear to catch the most problems here are (surprise!) not Caucasian.)

Whenever anyone leaps in and says “statement – I’m just sayin'” or “statement that challenges movements that are egalitarian – playing devil’s advocate” then I really must wonder ‘why?’ I have heard a number of people trying to sneak in sexist comments based on poor evidence or by playing the “Devil’s Advocate” card. “Wow, but what if women aren’t as good at X as men, playing Devil’s advocate/just sayin’/just askin’.” You know, that’s a good question. But it’s not the one that you’re asking. The question that I’m hearing (and I apologise because I have weird ears) is “How can I make a sexist statement with plausible deniability because I am not yet convinced that women are equal?”

This is about fundamental human rights, not an opinion on whether Picard or Kirk would win in a jello-wrestling competition. The questions that we ask, however they are framed, reveal what it is that we believe to be true. And right. And, by extension, what we consider false or wrong.

My real problem with all of this is that my students are like big mobile sponges. They hear a whole heap of stuff before they come to me and, if most of it is opinionated nonsense that magically escapes classification, they will learn that this is how the world works and come to me with a head full of garbage. They’ll recite rubbish at me that they’ve picked up from the world, politics, media, television and their own families that has no place in a University environment. I don’t give a hoot how entitled you feel to have a racist, sexist or discriminatory opinion, it’s going to get called as one and you can argue until you’re blue in the face that saying discriminatory things doesn’t make you discriminatory but, important point, you are almost never as ironically funny as you think you are. (And, yes, we all have to be aware of that. To my shame, I have occasionally gone too far in trying to mock discrimination and I apologetically confess that I have on occasion been less than funny and just plain dumb.) The important thing to ask is why are you trying to set up the situation in the first place?

My students have to think about these things all the time. They cannot guess how people will react to their dumb jokes and supposed ‘irony’. Worse, as people who have had the benefits of more education, other people will look to them (explicitly or not) as thought leaders and the best of my students will have a very wide-ranging impact. I can’t stop people saying silly and hurtful things, but let’s stop the pretence that there are special “get out of jail free” textual containers that allow people to utter the phrasings of discrimination and, yet, mysteriously escape being labelled as such.

(And, for the record, the Internet indicates that Picard would most likely take the match, given that he has mud wrestling experience.)
