The Complex Roles Of Universities In The Period Of Globalization – Altbach – Part 3

To finish this triptych, I’d like to look at Altbach’s assessment of contemporary issues. Private education providers are one of the most obvious recent developments and, with the erosion of the public good motivator, this is no real surprise. It’s less of a surprise when you affix the word “Profit-making” in front of the words ‘education provider’. Given that there is growing demand for education and also given that we are blurring the lines between the institutions, it becomes easy to see why a new market has exploded for people who wish to provide education, or something like it, at a reasonable fee with a possibility of making lots and lots of money. This, however, has an impact on the public sector because it reduces the students who may have come to us for a variety of reasons, especially when the private institutions are targeting the more wealthy in some way. Suddenly, we find ourselves having to justify which kinds of knowledge we are teaching in the public sector because the type of knowledge, and the jobs it leads to, become an issue when you are competing for students inside certain professional areas. Faculties of Arts across the world are very much feeling themselves caught in this pinch. It is hard to imagine many older Universities making such a bald statement such as “There is no need for History or English Scholars”, yet by pumping resources into their professional and technical streams they are saying it through their resource distribution. If something does not provide income or attract the right market, a jaded eye is cast across it and, depending on the wealth and capacity of the institution, this leads to the shutting down of schools or entire faculties.

Why is this such a problem? Because restarting a discipline is much harder once the number of participants drops down too far. Reduce the number of people in a discipline and their shared publications and venues also shrink. Given that publication is vital to perceived success in many ways, this shrinkage will make it harder to publish OR lead to accusations of irrelevance as the overall citation level drops because there are so few people in the area. We are so heavily measured and assessed, as individuals and as universities, that we are beleaguered by league tables and beset by set publication standards. Our management structures, modes of accountability, the way that we have worked and thought for centuries are not a good fit for this new modality. This is not the golden age ramblings that I have previously pointed to as dreaming of better days – in this case, it’s true. Our systems don’t work with the new expectations.

Opening ourselves up to students from anywhere is a noble goal, and one I support wholeheartedly, but it brings great challenge. Can we pursue anything that interests us, relevant or not, and expect to meet the demands of the new century? If we can, I don’t think we can do it with the systems that we have and certainly not while we’re being measured on externally applied metrics of success. Even deciding on whether a student should be admitted or not is now a matter of school ranking, bonus points, place availability, status and, in murkier waters, the two speed entry system of public and privately-funded places in the same institution, where admitting one party may (in the worst case) prevent another from entering. As Altbach notes, our ideas of governance are changing as our scale grows and our complexity increases. Senior Professors used to set our course but now we either need or have taken on trained administrators who do not think as we do, have not had our training and, in many ways, treat us as a standard business with a strange product. We are more accountable than ever, while we wander around being randomly measured and trying to work out what it is that we need to do in order to be measured accurately and then try and perform our tasks of learning, teaching and research. How do we reconcile the community of scholars with the bureaucracies that run our institutions?

Altbach then moves on to discuss developing countries and the special challenges that they face. Many of these countries have broken links to their indigenous cultures, due to colonisation, occupation, war and civil unrest, and, when combined with the colonial trend to keep investment in higher education low, this means that many of these countries are systematically disadvantaged. Their systems are so small that expansion is hard – insufficient training grounds for new educators, delay in building and resource appropriation and the threat of instability combine to make it very hard to kickstart anything. Poverty and lack of local government resources move some of these attempts across to the ‘impossible’ category. As it becomes hard to limit enrolments, overcrowding is the norm and, while you can’t limit enrolment, you can use draconian measures to ensure that anyone who falls behind is ejected, in the hope that freeing up that slot might ease some of the crush on the resources. This is a very unforgiving approach to education: you have one chance, you blew it, goodbye. Given that this is one of the only paths out of poverty in many of these countries, and that it is very easy to fall behind in a poor and resource-starved system, this is a nasty little feedback loop. Where other institutions are built up in response to demand, these newer academies tend not to offer the same level of education and we once again have the problem of a piece of paper that is not as worthy as another: we are providing education in name only and creating yet another two-speed system. Where the job market and the educational bodies don’t keep up with each other you may have that most awful ghetto: the educated unemployed, who have invested time and money into a degree that grants them no advantage at all.

Where we are over-stretched, we tend to only do those things that generate the most benefit and this is also true in the case of these third world Universities. Teaching earns money so teaching dominates. Research is sidelined, international collaboration is sidelined and staff have no time to do anything except teach because they are trying to keep their salary coming. Unsurprisingly, this is not a stage set of excellence and advancement – these universities are falling further and further behind.

Altbach concludes by talking about the pressure that we are all under and that have made the majority of our institutions reactive, limiting our creativity to solving pressing problems in a response to external pressures. Right now, we are running so fast that we do not have time to question why we are even on this treadmill, let alone take any real steps to make serious change that is truly strategic rather than reactive. We have lost our autonomy to a degree, as well as our identity. We are enmeshed in society but in a role that favours the market forces and makes us dance in response to it. Altbach ponders what our role should be and proposes a move towards the broader public interest, moving away from market forces and towards academic autonomy.This is not the selfish “leave me alone” cry of a spoiled child, this is a recognition of the fact that we have many more things to offer than a diploma and a vocation: universities are societies of thinkers and are far more complex and diverse than our current strictures would make us appear. All universities are important, says Altbach, and it is at society’s peril that it ignores the many roles that a University can provide. Looking at us as profit-making, degree factories, or as an elite streaming system, ignores the grand public benefit of an educated society, the value of the public intellectual and the scholarly community. We deserve support, says Altbach, because serve the goals of society and the individual. Let us do our jobs properly.

I found it to be a very interesting article to read and I hope I’ve capture the essence reasonably well. I look forward to discussing it! Thanks again, RV!

The Complex Roles Of Universities In The Period Of Globalization – Altbach – Part 2

Posted: September 24, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , , | Leave a comment

Continuing from my previous post, Altbach deals with the University as a focus of the international community. We host other people, share interests, cross-populate each other with PhD students and professors – sometimes it’s a wonder that we don’t get spontaneous germination of new Universities just from all of the swapping! Because of our mission, we tend to have a much greater ability to look, think and act on the international level. This is an interesting contrast to the role of the Uni as a national stabiliser, as the more one travels and looks outward, the more one realises that your country is just one of many. I travel a fair bit for work and I can tell you that, right now, I haven’t run across a single issue that is not being felt by at least two (or more) Universities at an equal level of pain, yet most people who don’t travel or share their world view feel isolated and that “no one else would understand.” The realisation that all countries are really very similar (yes, with one or two exceptions) and that Unis are the same all over the world sets the academic even further away from the people outside and again increases the obligation to communicate with people outside of academia. Hoarding knowledge or sneering at the uninformed do not come with the territory – Universities have traditionally been the centres of connectivity, even before the internet, and now that most Unis end up being the default Internet distribution point in many regions, this is becoming even more important.

This ties in with the next topic that Altbach mentions, our role in social mobility. Education transforms people. While you have to the son of the King to (most likely) become King, anyone can become an engineer (with a few caveats, to keep my colleagues in Eng happy!) with access to education. Expanding Universities from a small and elite focussed approach to a larger scale, massified, model has brought access and equity to a much larger group of people. This is not a given, of course, as the first-in-family do face a lot of challenges but, where the right attention is given to support and scholarships, great things can be achieved.

We are also engines for economic development, in that our knowledge can be commercialised, spun-off, licensed and re-used, through adjacent Science and Technology Parks or through relationships with industry. There are entire twins in the US that would shrivel up overnight without their co-located University. Academic research is still a key driver in innovation both directly and indirectly, through the production of research staff who then go to corporate research facilities.

But a number of these are fairly recent developments. International focus requires knowing about the world and having a method of travel, as well as not being at war with the place you’re trying to visit! The change from small and elite to large and massive requires vast amounts of money and resources and the changes have taken place with staggered effects across most of the second half of the 20th Century, into this new century. It’s not just the number of students, Altbach emphasises, it’s the range of post-secondary options that have sprung up to meet technical and industrial demand. These new institutions have new charters, new focus areas, different lengths and types of degree and we suddenly find that, much as oranges are not the only fruit, training at a University that can grant PhDs may not be the best preparation for working at an institution that is post-secondary yet nothing much like the places that its teachers have come from. The ‘pinnacle’ research institutions, prestigious and few in number, serve a smaller group and are probably the most complex institutions in the spectrum, training the most professionals and receiving the lion’s share of research funding. This introduces tension, between the doctoral graduates of the pinnacle who may transfer to other institutions and find themselves at odds with a very different mission, and because any system where an entrenched elite receive advantages that allow them to stay elite is always going to cause tension. Massification has led to greater disparity. Yes, almost anyone can go to college, but it appears that achieving that has meant that we have now risked devaluing the term ‘college’ along the way. In Australia, students say they’re going to ‘Uni’ when that could mean TAFE (Technical and Further Education), adult education, or actual University. (We had a comprehensive shake-up some time ago that turned all of the institutes of technology into Universities, or we would have that distinction as well. The previous separation of degrees and ‘applied’ degrees had actually worked quite well, at least in my reading and opinion, but government initiatives are what they are, and we will talk more about this in the discussion of public and private good.) Should it matter what one does when the word ‘college’ is mentioned? No, it shouldn’t. The problem is when the issue becomes confusing or we provide a service that we call ‘college’ to all of our citizens, yet some citizens get a better version than others for reasons that are not transferable or equitable. To quote Altbach:

Massification inevitably creates more variations and diversity in academic systems. It creates opportunities for access that are unprecedented in world history, but at the same time it creates systems that are less equal and more difficult to support financially.

This brings us squarely into Altbach’s next point, the issue of public versus private good, a debate that rages unabated today. Changes in Australian University funding have very much been under the presumption that the greatest good is being enjoyed by the private citizen who receives the education, rather than the society to which they contribute, hence the citizen should bear more of the load for their own education. (My response is ‘piffle’, the benefit to our society of the educated is hard to overestimate,  but I’ve already discussed this in an earlier post.) As noted in the article, whether the state can or cannot support public education is moot as many states are just shifting the burden to the citizen and their families. This inevitably creates a two-speed system, where some go to college and some do not, because of influences and decisions that may have had an impact on the grandparents and parents of the student, rather than any personal merit. Given that, even in a meritocratic system, training programs and preparation schools can make all the difference, and these are usually private and expensive, any meritocratic system risks quickly falling into the same two-speed divide. Even if a place is available at the correct type of institution, the costs of relocating, leaving a secure community and moving from a more socialised and low-cash environment to an isolated, pay-up-front and distant location to attend a college may place another bar in the way of the prospective student from a less advantaged area. Mass higher education is supposed to be for the masses but solving the issues of nomenclature, access and preparation do nothing if no-one can actually attend unless they’re rich. Many of our activities are linked, in one way or another, to the public good and we are well aware that feeling that you are an active and contributing member of your society is usually associated with greater motivation to participate and be involved with this good. Any restrictive mechanisms driven by forcing the burden back on to the citizen, defended by the notion of personal benefit dominates any public benefit, undermine the ability of people to join and contribute to greater society: this undermines the public good, as well as setting the stage for disenfranchisement and a disengagement from society. Every time we do this, we risk casting another generation out of the circle of those who will go to college.

I’ll finish this tomorrow, with a discussion of the contemporary issues, from the report, and my own thoughts overall.

The Complex Roles Of Universities In The Period Of Globalization – Altbach – Part 1

Posted: September 23, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , , , | Leave a comment

One of the most handy things about having a new member in a research group, especially one who is just finishing or has just finished submitting a PhD, is that they come in with an entirely new subset of the possible papers in the given discipline, which they have used to construct their theses and inform their thinking. While you will have the standard overlap of the key papers in the field, there will often be waterways that run away from the main river and it is in these diverse streams that we find new ways of thinking, even leading to these stream becoming tributaries that feed back into our main body, strengthening the overall work.

R has just sent me a reference from her thesis, a copy of Altbach’s 2011 publication in Higher Education in the World 3: New Challenges and Emerging Roles for Human and Social Development, entitled “The Complex Roles Of Universities In The Period Of Globalization”. The abstract is pithy but this quote stands out: “The academic drift of the 21st century raises concerns about the core functions of universities and how contemporary changes have affected academic missions.” This is a fascinating paper and one that I wish I turned up early because it has the same concerns as I do, and as Richard Hil did with his Whackademia book, in that we are all being asked to do more with less and it is how we do this that will decide our future, and the future of higher education. (Readers may recall that I did not agree with much of what Hil said – as I said, I wish I had read Altbach sooner because it would have made the rebuttal easier.) I’m going to cover this across a few posts because the paper has a fair bit of comment and I’d like to make some commentary!

Altbach looks at the different roles that Universities have had over time, including the different roles that they play in certain countries and how time, politics, religion, wealth and nationalism have all contributed to changing demands on the sector. There is no doubt that teaching and research make up our core functions but we can vary from country to country as to whether we are teaching technical skills, professional skills or general education at Universities. Over time, we have often been in conflict with our own societies, which can lead to great creativity but at the cost of additional load or difficult burdens. Research is equally difficult to pin down: are we talking ‘pure’ research or ‘applied’ research? Does research have to be discipline focused or can we perform research on teaching, or research on research? Does it matter where the research money comes from? Different areas inside the same university can have completely different answers to these questions so it’s little doubt that this question is still open!

Universities have been used to foster national development and identity, as Altbach mentions with German, Japanese and American examples, or as stabilising influences in the third world. We are also steadily evolving academic centres, adding courses as the ranks of the professions grow. My profession, Computer Scientist, wasn’t even a profession until the second half of the 20th century (that’s why we have so few cool awards – there is no Nobel prize in Applied Algorithmics). Immediately we see a conflict in the sense of stability and status quo required to be a national touchstone, while determining how we adapt to the changing demands of the workforce and the new professionals.

We have always been associated with knowledge as both the defenders and disseminators, ignoring secular and religious demand to not teach certain things or to state that red is black, with a focus on organisation to facilitate later retrieval. This access to knowledge also feeds in to one of our other key facets, or at least one of the most desirable, that of an intellectual centre. As academics, we have the freedom to express our ideas and, many would argue, the obligation to do so given that we have that freedom. The expertise that our staff have should be available to all in terms of interpretation and refinement of ideas and concepts but to do that we have to engage with the community. It is of little surprise that we often find ourselves involved in social and political movements, supporting other activists, providing resources and making an overall contribution to the intellectual life of our surroundings.

This is, for me, a very important point because it forces us to consider where the private individual ends and the public intellectual begins, if such a division even makes any sense. From a personal perspective, I would not raise my politics in a classroom but I would discuss issues of ethics and equality, some of which may or may not be in accord with prevailing government thought. Let me be more explicit. Yesterday, I attended a rally for Marriage Equality, as part of a reaction against the Australian Federal Government’s rejection of a bill to allow same sex marriage. I would most certainly not have advertised this event in my lectures or told my students about it because I think that there’s far too much capacity for me to influence my students to act through our relationship, which is not a discussion or political sharing but overt influence. I attended the rally as a private citizen but if my students asked me about it, because we did get photographed and videoed, then I feel that I could explain my actions within an ethical framework, which means that this is informing my role as public intellectual. My community, equality and ethical focus drives both the citizen and the academic and allows me to carry out two roles while attempting to minimise any exploitation of the power relationship that I have with my students. However, my capacity as a (notional) public intellectual requires me to have an explanation for what I did that is articulate and comprehensible. The private citizen is impassioned but the academic is both passionate and rationale, and can place the activity in a context that allows it to be shared.

But, as I always say, there is no point having a system that only works with perfect people. Altbach is talking about our institutions, which is the right focus for the paper, but the institutions are just buildings without the academics and students that fill them. I attempt to juggle my private and public self and, while sometimes I succeed more than others, I think I know what I should ‘look like’ to my institution, my peers, my students and my social groups. What will be interesting in the coming world of change for Universities is how we deal with the people who don’t work as well within the role of educator. I have no time, respect or tolerance for those of my colleagues who confuse intellectual freedom with a wanton disregard for reasonable behaviour in this privileged role. Just because we organise the knowledge doesn’t mean that we own it, nor does our mastery of intellectual pursuits (if we achieve that) make us any better than anyone else: we have merely had more opportunity but, for me, that comes with a corresponding level of responsibility. I have seen more than one academic, not at my own University I hasten to add, who has obviously been grooming a student through manipulation of the aura of competency that any decent academic can muster, where we appear wise, worldly and incredibly, staggeringly, deep on matters that are so very, very passionate and important. Altbach writes of what changes we have seen in Universities but you only have to read through the yellow press (or the FFFF00 press on the web) to see how many educators are abusing their relationship with their students and I’m not sure what this says about how the educators themselves are changing. I have heard dire tales of exploitative behaviour in the 70s and 80s in my country – “A for a lay” unpleasantness and similar. When we talk of our intellectual freedoms, our influence on the world as national stabilisers and centres of knowledge, it is important to remember that the components of these institutions are merely people. As we increase the stresses on the organisations, so too do we distribute this across people and, given that people are already failing some key moral and disciplinary requirements, any discussion of what our role should become will have to take into account the fact that we are building a system from people, to work with other people.

The Philosophical Angle

Socrates drank hemlock after being found guilty of corrupting the minds of the youth of Athens, and impiety. Seneca submitted to the whims of Nero when the Emperor, inevitably, required that his old tutor die. Seneca’s stoicism was truly tested in this, given that he slashed his veins, took poison, jumped in a warm bath and finally had to be steamed to death before Nero’s edict that he kill himself was finally enacted. I, fortunately, expect no such demonstrations of stoic fortitude from my students but, if we are to think about their behaviour and development as self-regulating beings, then I think that a discussion of their personal philosophy becomes unavoidable. We have talked about the development state, their response to authority, their thoughts on their own thinking, but what of their philosophy?

If you are in a hurry and jump in your car, every red light between you and your destination risks becoming a personal affront, an enraging event that defies your expectation of an ‘all-green’ ride into town. There is no reason why you should expect such favours from the Universe, whatever your belief system, but the fact that this is infuriating to you remains. In the case of the unexpected traffic light, which sounds like the worst Sherlock Holmes story ever, the worst outcome is that you will be late, which may have a variety of repercussions. In preparing assignment work, however, a student may end up failing with far more dire and predictable results.

“Watson, I shall now relate the entire affair through Morse tapped pipe code and interpretative dance.”

While stoicism attracts criticism, understandably, because it doesn’t always consider the fundamentally human nature of humans, being prepared for the unforeseen is a vital part of any planning process. Self-regulation is not about drawing up a time table that allows you to fit in everything that you know about, it is about being able to handle your life and your work when things go wrong. Much as a car doesn’t need to be steered when it is going in a straight line and meeting our requirements, it is how we change direction when we know the road and when a kangaroo jumps out that are the true tests of our ability to manage our resources and ourselves.

Planning is not everything, as anyone who has read Helmuth von Moltke the Elder or von Clausewitz will know: “no plan survives contact with the enemy”. In this case, however, the enemy is not just those events that seek to confound us, it can be us as well! You can have the best plan in the world that relies upon you starting on Day X, and yet you don’t. You may have excellent reasons for this but, the fact remains, you have now introduced problems into your own process. You have met the enemy and it is you. This illustrates the critical importance of ensuring that we have an accurate assessment of our own philosophies – and we do have to be very honest.

There is no point in a student building an elaborate time management plan that relies upon them changing the habits of a lifetime in a week. But this puts the onus upon us as well: there is no point in us fabricating a set of expectations that a student cannot meet because they do not yet have a mature philosophy for understanding what is required. We don’t give up (of course!) but we must now think about how we can scaffold and encourage such change in a manageable way. I find reflection very handy, as I’ve said before, as watching students write things like “I planned for this but then I didn’t do it! WHY?” allows me to step in and discuss this at the point that the student realises that they have a problem.

I am not saying that a student who has a philosophy of “Maybe one day I will pass by accident” should be encouraged to maintain such lassitude, but we must be honest and realise that demanding that their timeliness and process maturity spring fully-formed from their foreheads is an act of conjuring reserved only for certain Greek Gods. (Even Caligula couldn’t manage it and he had far greater claim to this than most.) I like to think of this in terms of similarity of action. If anything I do is akin to walking up to someone and yelling “You should hand in on time, do better!” then I had better re-think my strategy.

The development of a personal philosophy, especially when you may not have ever been exposed to some of the great exemplars, is a fundamentally difficult task. You first need to understand that such a concept exists, then gain the vocabulary for discussing it, then interpret your current approach and see the value of change. Once you have performed all of those tasks, then we can start talking about getting from A to B. If you don’t know what I’m talking about or can’t understand why it’s important, or even discuss core concepts, then I’m yelling at you in the corridor and you’ll nod, compliantly, until I go away. Chances of you taking positive steps in the direction that I want? Very low. Probably, nil. And if it does happen, either it’s accidental or you didn’t actually need my help.

I try to be stoic but I must be honest and say that if Nero sentenced me to death, I’d nod, say “I expected that”, then put on some fast saxophone music and leg it up over the seven hills and far away. I don’t think I’d ever actually expect true stoicism from most of my students. but a simple incorporation of the fact that not everything works out as you think it will would be a definite improvement over the current everything will work out in my favour expectation that seems to be the hallmark of the more frequently disappointed and distressed among them. The trick is that I first have to make them realise that this is something that, with thought, they can not only fix but use to make a genuine, long-lasting and overwhelmingly positive change in their lives.

A Puzzling Thought

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

Today I presented one of my favourite puzzles, the Monty Hall problem, to a group of Year 10 high school students. Probability is a very challenging area to teach because we humans seem to be so very, very bad at grasping it intuitively. I’ve written before about Card Shouting, where we appear to train cards to give us better results by yelling at them, and it becomes all too clear that many people have instinctive models of how the world work that are neither robust nor transferable. This wouldn’t be a problem except that:

  1. it makes it harder to understand science,
  2. the real models become hard to believe because they’re counter-intuttitve, and
  3. casinos make a lot of money out of people who don’t understand probability.

Monty Hall is simple. There are three doors and behind one is a great prize. You pick a door but it doesn’t get opened. The host, who knows where the prize is, opens one of the doors that you didn’t pick but the door that he/she opens is always going to be empty. So the host, in full knowledge, opens a known empty door, but it has to be one that you didn’t pick. You then have a choice to switch to the door that you didn’t pick and that hasn’t been opened, or you can stay with your original pick.

Based on a game show, Monty Hall was the name of the presenter.

Now let’s fast forward to the fact that you should always switch because you have a 2/3 chance of getting the prize if you do (no, not 50/50) so switching is the winning strategy. Going into today, what I expected was:

  • Initially, most students would want to stay with their original choice, having decided that there was no benefit to switching or that it was a 50/50 deal so it didn’t make any sense.
  • At least one student would actively reject the idea.
  • With discussion and demonstration, I could get students thinking about this problem in the right way.

The correct mental framework for Monty Hall is essential. What are the chances, with 1 prize behind 3 doors, that you picked the right door initially. It’s 1/3, right? So the chances that you didn’t pick the correct door is 2/3. Now, if you just swapped randomly, there’d be no advantage but this is where you have to understand the problem. There are 2 doors that you didn’t pick and, by elimination, these 2 doors contain the prize 2/3 of the time. The host knows where the prize is so the host will never open a door and show you the prize, the host just removes a worthless door. Now you have two sets of doors – the one you picked (correct 1/3 of the time) and the remaining door from the unpicked pair (correct 2/3 of the time). So, given that there’s only one remaining door to pick in the unpicked pair, by switching you increase your chances of winning from 1/3 to 2/3.

Don’t believe me? Here’s an on-line simulator that you can run (Ignore what it says about Internet Explorer, it tends to run on most things.)

Still don’t believe me? Here’s some Processing code that you can run locally and see the rates converge to the expected results of 1/3 for staying and 2/3 for switching.

This is a challenging and counter-intuitive result, until you actually understand what’s happening, and this clearly illustrates one of those situations where you can ask students to plug numbers into equations for probability but, when you actually ask them to reason mathematically, you suddenly discover that they don’t have the correct mental models to explain what is going on. So how did I approach it?

Well, I used Peer Instruction techniques to get the class to think about the problem and then vote on it. As expected, about 60% of the class were stayers. Then I asked them to discuss this with a switcher and to try and convince each other of the rightness of their actions. Then I asked them to vote again.

No significant change. Dang.

So I wheeled out the on-line simulator to demonstrate it working and to ensure that everyone really understood the problem. Then I showed the Processing simulation showing the numbers converging as expected. Then I pulled out the big guns: the 100 door example. In this case, you select from 100 doors and Monty eliminates 98 (empty) doors that you didn’t choose.

Suddenly, when faced with the 100 doors, many students became switchers. (Not surprising.) I then pointed out that the two problems (3 doors and 100 doors) had reduced to the same problem, except that the remaining doors were the only door left standing from 2 and 99 doors respectively. And, suddenly, on the repeated vote, everyone’s a switcher. (I then ran the code on the 100 door example and had to apologise because the 99% ‘switch’ trace is so close to the top that it’s hard to see.)

Why didn’t the discussion phase change people’s minds? I think it’s because of the group itself, a junior group with very little vocabulary of probability. it would have been hard for the to articulate the reasons for change beyond much ‘gut feeling’ despite the obvious mathematical ability present. So, expecting this, I confirmed that they were understanding the correct problem by showing demonstration and extended simulation, which provided conflicting evidence to their previously held belief. Getting people to think about the 100 door model, which is a quite deliberate manipulation of the fact that 1/100 vs 99/100 is a far more convincing decision factor than 1/3 vs 2/3, allowed them to identify a situation where switching makes sense, validating what I presented in the demonstrations.

In these cases, I like to mull for a while to work out what I have and haven’t learned from this. I believe that the students had a lot of fun in the puzzle section and that most of them got what happened in Monty Hall, but I’d really like to come back to them in a year or two and see what they actually took away from today’s example.

 

De Profundis – or de-profounding?

“It is common to assume that we are dealing with a highly intelligent book when we cease to understand it.” (de Botton, The Consolations of Philosophy, p157)

The notion of a lack of comprehension being a fundamental and innate fault of the reader, rather than the writer, is a mistake made, in many different and yet equally irritating ways, throughout the higher educational sector. A high pass rate may be seen as indicative of an easy course or a weak marker. A high failure rate may be attributed to the innate difficulty of the work or the inferior stuff of which the students are made. As I have written before, under such a presumption, I could fail all of my students and strut around, the smartest man in my University, for none have been able to understand the depths and subtlety of my area of knowledge.

Yet, if the real reason is that I have brought my students to a point where their abilities fail them and, either through ignorance or design, I do not strive to address this honestly and openly, then it doesn’t matter how many of them ultimately pass – I will be the biggest failure in the class. I know a great number of very interesting and intelligent educators but, were you to ask me if any of them could teach, I would have to answer that I did not know, unless I had actually seen them do so. For all of our pressure on students to contain the innate ability to persevere, to understand our discipline or to be (sorry, Ray) natural programmers, the notion that teaching itself might not be something that everyone is capable of is sometimes regarded as a great heresy. (The notion or insistence that developing as a teacher may require scholarship and, help us all, practise, is apostasy – our heresy leading us into exile.) Teaching revolves around imparting knowledge efficiently and effectively so that students may learn. The cornerstone of this activity is successful and continuing communication. Wisdom may be wisdom but it rapidly becomes hard to locate or learn from when it is swaddled in enough unnecessary baggage.

I have been, mostly thanks to the re-issue of cheap Penguins, undertaking a great deal of reading recently and I have revisited Marcus Aurelius, Seneca, de Botton and Wilde. The books that are the most influential upon me remain those books that, while profound, maintain their accessibility. Let me illustrate this with an example. For those who do not know what De Profundis means, it is a biblical reference to Psalm 130, appropriated by the ever humble Oscar Wilde as the title of his autobiographical letter to his former lover, from the prison in which he was housed because of that love.

But what it means is “From the depths”. In the original psalm, the first line is:

De profundis clamavi ad te, Domine;
From the depths, I have cried out to you, O Lord;

And in this reading, we see the measure of Wilde’s despair. Having been sentenced to hard labour, and having had his ability to write confiscated, his ability to read curtailed, and his reputation in tatters, he cries out from the depths to his Bosie, Lord Douglas.

De profundis [clamavi ad te, Bosie;]

If you have the context for this, then this immediately prepares you for the letter but, as it is, the number of people who are reading Wilde is shrinking, let alone the number of people who are reading a Latin Bible. Does this title still assist in the framing of the work, through its heavy dependence upon the anguish captured in Psalm 130, or is it time to retitle it “From the depths, I have cried out to you!” to capture both the translation and the sense. The message, the emotion and the hard-earned wisdom contained in the letter are still valuable but are we hurting the ability of people to discover and enjoy it by continuing to use a form of expression that may harm understanding?

Les Très Riches Heures du duc de Berry, Folio 70r – De Profundis the Musée Condé, Chantilly. (Another form of expression of this Psalm.)

Now, don’t worry, I’m not planning to rewrite Wilde but this raises a point in terms of the occasionally unhappy union of the language of profundity and the wisdom that it seeks to impart. You will note the irony that I am using a heavily structured, formal English, to write this and that there is very little use of slang here. This is deliberate because I am trying to be precise while still being evocative and, at the same time, illustrating that accurate use of more ornate language can obscure one’s point. (Let me rephrase that. The unnecessary use of long words and complex grammar gets in the way of understanding.)

When Her Majesty the Queen told the Commonwealth of her terrible year, her words were:

“1992 is not a year on which I shall look back with undiluted pleasure. In the words of one of my more sympathetic correspondents, it has turned out to be an Annus Horribilis.”

and I have difficulty thinking of a more complicated way of saying “1992 was a bad year” than to combine a complicated grammatical construction with a Latin term that is not going to be on the lips of the people who are listening to the speech. Let me try: “Looking back on 1992, it has been, in the words of one of my friends, a terrible year.” Same content. Same level of imparted knowledge. Much less getting in the way. (The professional tip here is to never use the letters “a”, “n”, “s” and “u” in one short word unless you are absolutely sure of your audience. “What did she say about… nahhh” is not the response you want from your loyal subjects.) [And there goes the Knighthood.]

I love language. I love reading. I am very lucky that, having had a very broad and classically based education, I can read just about anything and not be intimidated or confused by the language forms – providing that the author is writing in one of the languages that I read, of course! To assume that everyone is like me or, worse, to judge people on their ability because they find long and unfamiliar words confusing, or have never had the opportunity to use these skills before, is to leap towards the same problem outlined in the quote at the top. If we seek to label people unintelligent when they have not yet been exposed to something that is familiar to us, then this is just as bad as lauding someone’s intelligence because you don’t understand what they’re talking about.

If my students need to know something then I have to either ensure that they already do so, by clearly stating my need and being aware of the educational preparation in my locale, or I have to teach it to them in forms that they can understand and that will allow them to succeed. I may love language, classical works and big words, but I am paid to teach the students of 2012 to become the graduates, achievers and academics of the future. I have to understand, respect and incorporate their context, while also meeting the pedagogical and knowledge requirements of the courses that I teach.

No-one said it was going to be easy!

The Narrative Hunger: Stories That Meet a Need

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

I have been involved in on-line communities for over 20 years now and, apparently, people are rarely surprised when they meet me. “Oh, you talk just like you type.” is the effective statement and I’m quite happy with this. While some people adopt completely different personae on-line, for a range of reasons, I seem to be the same. It then comes as little surprise that I am as much of storyteller in person as I am online. I love facts, revel in truth, but I greatly enjoying putting them together into a narrative that conveys the information in a way that is neither dry nor dull. (This is not to say that the absence of a story guarantees that things must be dry and dull but, without a focus on those elements of narrative that appeal to common human experience, we always risk this outcome.)

One of Katrina’s recent posts referred to the use of story telling in education. As she says, this can be contentious because:

stories can be used to entertain students, to have them enjoy your lectures, but are not necessarily educational.

The shibboleth of questionable educational research is often a vaguely assembled study, supported by the conjecture that the “students loved it”, and it is very easy to see how story telling could fall into this. However, we as humans are fascinated by stories. We understand the common forms even where we have not read Greek drama or “The Hero With a Thousand Faces”. We know when stories ring true and when they fall flat. Searching the mental engines of our species for the sweet spots that resonate across all of us is one way to convey knowledge in a more effective and memorable way. Starting from this focus, we must then observe our due diligence in making sure that our story framework contains a worthy payload.

Not all stories are of the same value.

I love story telling and I try to weave together a narrative in most of my lectures, even down to leaving in sections where deliberate and tangential diversion becomes part of the teaching, to allow me to contrast a point or illuminate it further by stripping it of its formal context and placing it elsewhere. After all, an elephant next to elephants is hardly memorable but an elephant in a green suit, as King of a country, tends to stick in the mind.

The power of the narrative is that it involves the reader or listener in the story. A well-constructed narrative leads the reader to wonder about what is going to happen next and this is model formation. Very few of us read in a way where the story unfolds with us completely distant from it – in fact, maintaining distance from a story is a sign of a poor narrative. When the right story is told, or the right person is telling it, you are on the edge of your seat, hungry to know more. When it is told poorly, then you stifle a yawn and smile politely, discreetly peering at your watch as you attempt to work out the time at which you can escape.

Of course, this highlights the value of narrative for us in teaching but it also reinforces that requirement that it be more than an assemblage of rambling anecdotes, it must be a constructed narration that weaves through points in a recognisable way and giving us the ability to conjecture on its direction. O. Henry endings, the classic twist endings, make no sense unless you have constructed a mental model that can be shaken by the revelations of the last paragraphs. Harry Potter book 7 makes even less sense unless one has a model of the world in which the events of the book can be situated.

As always, this stresses the importance of educational design, where each story, each fact, each activity, is woven into the greater whole with a defined purpose and in full knowledge of how it will be used. There is nothing more distracting than someone who rambles during a lecture about things that not only seem irrelevant, but are irrelevant. Whereas a musing on something that, on first glance, appears irrelevant can lead to exploration of the narrative by students. Suddenly, they are within a Choose Your Own Adventure book and trying to work out where each step will take them.

Stories are an excellent way to link knowledge and problems. They excite, engage and educate, when used correctly. We are all hungry for stories: we are players within our own stories, observers of those of the people around us and, eventually, will form part of the greater narrative by the deeds for which we are written up in the records to come. It makes sense to use this deep and very human aspect of our intellect to try and assist with the transfer of knowledge.

Loading the Dice: Show and Tell

Posted: September 6, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , | Leave a comment

I’ve been using a set of four six-sided dice to generate random numbers for one of my classes this year, generally to establish a presentation order or things like that. We’ve had a number of students getting the same number and so we have to have roll-offs. Now in this case, the most common number rolled so far has been in the range of 17-19 but we have only generated about 18-20 rolls so, while that’s a little high, it’s not high enough to arouse suspicion.

Today we rolled again, and one student wasn’t quite there yet so I did it with the rest of the class. Once again, 18 showed up a bit. This time I asked the class about it. Did that seem suspicious? Then I asked them to look at the dice.

Oh.

Only two of the dice are actually standard dice. One has the number five on every face. One has three sixes and three twos. The students have seen these dice numerous times and have never actually examined them – of course, I didn’t leave them lying around for them to examine but, despite one or two starting to think “Hey, that’s a bit weird”, nobody ever twigged to the loading.

All of the dice in this picture are loaded through weight manipulation, rather than dot alteration. You can buy them for just about any purpose. Ah, Internet!

Having exposed this trick, to some amusement, the last student knocked on the door and I picked up the dice. He was then asked to roll for his position, with the rest of the class staying quiet. (Well, smirking.) He rolled something in 17-19, I forget what, and I wrote that up on the board. Then I asked him if it seemed high to him? On reflection, he said that these numbers all seemed pretty high, especially as the theoretical maximum was 24. I then asked if he’d like to inspect the dice.

He then did so, as I passed him the dice one at a time, and storing the inspected dice in my other hand. (Of course, as he peered at each die to see if it was altered, I quickly swapped one of the ‘real’ dice back into the position in my hand and, as the rest of the class watched and kept admirably quiet, I then forced a real die onto him. Magic is all about misdirection, after all.)

So, having inspected all of them, he was convinced that they were normal. I then plonked them down on the table and asked him to inspect them, to make sure. He lined them up, looked across the top face and, then, looked at the side. Light dawned. Loudly! What, of course, was so startling to him was that he had just inspected the dice and now they weren’t normal.

What was my point?

My students have just completed a project on data visualisation where they provided a static representation of a dataset. There is a main point to present, supported by static analysis and graphs, but the poster is fundamentally explanatory. The only room for exploration is provided by the poster producer and the reader is bound by the inherent limitations in what the producer has made available. Much as with our discussions of fallacies in argument from a recent tutorial, if information is presented poorly or you don’t get enough to go on, you can’t make a good decision.

Enter, the dice.

Because I deliberately kept the students away from them and never made a fuss about them, they assumed that they were normal dice. While the results were high, and suspicion was starting to creep in, I never gave them enough space to explore the dice and discern their true nature. Even today, while handing them to a student to inspect, I controlled the exploration and, by cherry picking and misdirection, managed to convey a false impression.

Now my students are moving into dynamic visualisation and they must prepare for sharing data in a way that can be explored by other people. While the students have a lot of control over who this exploration takes place, they must prepare for people’s inquisitiveness, their desire to assemble evidence and their tendency to want to try everything. They can’t rely upon hiding difficult pieces of data in their representation and they must be ready for users who want to keep exploring through the data in ways that weren’t originally foreseen. Now, in exploratory mode, they must prepare for people who want to try to collect enough evidence to determine if something is true or not, and to be able to interrogate the dataset accordingly.

Now I’m not saying that I believe that their static posters were produced badly, and I did require references to support statements, but the view presented was heavily controlled. They’ve now seen, in a simple analogue, how powerful that can be. Now, it’s time to break out of that mindset and create something that can be freely explored, letting their design guide the user to construct new things rather than to lead them down a particular path.

I can only hope that they’re exceed by this because I certainly am!!

The Precipice of “Everything’s Late”

Posted: September 3, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , | 7 Comments

I spent most of today working on the paper that I alluded to earlier where, after over a year of trying to work on it, I hadn’t made any progress. Having finally managed to dig myself out of the pit I was in, I had the mental and timeline capacity to sit down for the 6 hours it required and go through it all.

Climbers, eh?

In thinking about procrastination, you have to take into account something important: the fact that most of us work in a hyperbolic model where we expend no effort until the deadline is right upon us and then we put everything in, this is temporal discounting. Essentially we place less importance on things in the future than the things that are important to us now. For complex, multi-stage tasks over some time this is an exceedingly bad strategy, especially if we focus on the deadline of delivery, rather than the starting point. If we underestimate the time it requires and we construct our ‘panic now’ strategy based on our proximity to the deadline, then we are at serious risk of missing the starting point because, when it arrives, it just won’t be that important.

Now, let’s increase the difficulty of the whole thing and remember that the more things we have to think about in the present, the greater the risk that we’re going to exceed our capacity for cognitive load and hit the ‘helmet fire’ point – we will be unable to do anything because we’ve run out of the ability to choose what to do effectively. Of course, because we suffer from a hyperbolic discounting problem, we might do things now that are easy to do (because we can see both the beginning and end points inside our window of visibility) and this runs the risk that the things we leave to do later are far more complicated.

This is one of the nastiest implications of poor time management: you might actually not be procrastinating in terms of doing nothing, you might be working constantly but doing the wrong things. Combine this with the pressures of life, the influence of mood and mental state, and we have a pit that can open very wide – and you disappear into it wondering what happened because you thought you were doing so much!

This is a terrible problem for students because, let’s be honest, in your teens there are a lot of important things that are not quite assignments or studying for exams. (Hey, it’s true later too, we just have to pretend to be grownups.) Some of my students are absolutely flat out with activities, a lot of which are actually quite useful, but because they haven’t worked out which ones have to be done now they do the ones that can be done now – the pit opens and looms.

One of the big advantages of reviewing large tasks to break them into components is that you start to see how many ‘time units’ have to be carried out in order to reach your goal. Putting it into any kind of tracking system (even if it’s as simple as an Excel spreadsheet), allows you to see it compared to other things: it reduces the effect of temporal discounting.

When I first put in everything that I had to do as appointments in my calendar, I assumed that I had made a mistake because I had run out of time in the week and was, in some cases, triple booked, even after I spilled over to weekends. This wasn’t a mistake in assembling the calendar, this was an indication that I’d overcommitted and, over the past few months, I’ve been streamlining down so that my worst week still has a few hours free. (Yeah, yeah, not perfect, but there you go.) However, there was this little problem that anything that had been pushed into the late queue got later and later – the whole ‘deal with it soon’ became ‘deal with it now’ or ‘I should have dealt with that by now’.

Like students, my overcommitment wasn’t an obvious “Yes, I want to work too hard” commitment, it snuck in as bits and pieces. A commitment here, a commitment there, a ‘yes’, a ‘sure, I can do that’, and because you sometimes have to make decisions on the fly, you suddenly look around and think “What happened”? The last thing I want to do here is lecture, I want to understand how I can take my experience, learn from it, and pass something useful on. The basic message is that we all work very hard and sometimes don’t make the best decisions. For me, the challenge is now, knowing this, how can I construct something that tries and defeats this self-destructive behaviour in my students?

This week marks the time where I hope to have cleared everything on the ‘now/by now’ queue and finally be ahead. My friends know that I’ve said that a lot this year but it’s hard to read and think in the area of time management without learning something. (Some people might argue but I don’t write here to tell you that I have everything sorted, I write here to think and hopefully pass something on through the processes I’m going through.)

Time Banking: More and more reading.

Posted: September 2, 2012 | Author: | Filed under: Education | Tags: , , , , , , , , , , , , , , , , | Leave a comment

I’ve spent most of the last week putting together the ideas of time banking, reviewing my reading list and then digging for more papers to read and integrate. It’s always a bit of a worry when you go to see if what you’ve been thinking about for 12 months has just been published by someone else but, fortunately, most people are still using traditional deadlines so I’m safe. I read a lot of papers but none more than when I’m planning or writing a paper: I need to know what else has happened if I’m to frame my work correctly and not accidentally re-invent the wheel. Especially if it’s a triangular wheel that never worked.

My focus is Time Banking so that’s what I’ve been searching for – concepts, names, similarities, to make sure that what I’m doing will make an additional contribution. This isn’t to say that Time Banking hasn’t been used before as a term or even a concept. I’ve been aware of several universities who allow a fixed number of extra days that students can draw on (Stanford being the obvious example) and the concept of banking your time is certainly not new – there’s even a Dilbert cartoon for it! There are papers on time banking, at low granularity and with little student control – it’s more of a convenient deadline extender rather than a mechanism for developing metacognition in order to promote self-regulating learning strategies in the student. Which is good because that’s the approach I’m taking.

The reasoning and methodology that I’m using does appear to be relatively novel and it encompasses a whole range of issues: pedagogy, self-regulation, ethics and evidence-based analysis of how deadlines are currently working for us. It’s a lot to fit into one paper but I have hope that I can at least cover the philosophical background of why what I’m doing is a good idea, not just because I want to convince my peers but because I want volunteers for when pilot schemes start to occur.

It’s not enough that something is a good idea, or that it reads well, it has to work. It has to be able to de deployed, we have to be able to measure it, collect evidence and say “Yes, this is what we wanted.” Then we publish lots more papers and win major awards – Profit! (Actually, if it’s a really good idea then we want everyone to do it. Widespread adoption that enhances education is the real profit.)

Like this but with less underpants collecting and more revolutionising education.

More seriously, I love writing papers because I really have to think deeply about what I’m saying. How does it fit with existing research? Has this been tried before? If so, did it work? Did it fail? What am I doing that is different? What am I really trying to achieve?

How can I convince another educator that this is actually a good idea?

The first draft of the paper is written and now my co-authors are scouring it, playing Devil’s advocate, and seeing how many useful and repairable holes they can tear in it in order to make it worthy of publication. Then it will go off at some point and a number of nice people will push it out to sea and shoot at it with large weapons to see if it sinks or swims. Then I get feedback (and hopefully a publication) and everyone learns something.

I’m really looking forward to seeing the first actual submission draft – I want to see what the polished ideas look like!
