Rabbit Has Stopped Running

A healthy male adult bore consumes each year one and a half times his own weight in other people's patience.

I love Russell Baker. I subscribe to the RSS feed for the New York Review of Books, in large part so I can track his pieces there. His latest is a review of several new books about FDR, the first 100 days of his administration. There were two big lessons for me. Fascism was in the air. Of course we all know about Hitler and Mussolini. But I didn’t realize that in the U.S. there was a big push for Roosevelt to adopt dictatorial powers, working on legislation with Congress would be just too slow so he should do it all himself. Fortunately that didn’t happen. Congress gave Roosevelt what he wanted and he produced a whirlwind of programs with the alphabet soup labels.

The other bit I learned is that going into the Presidency FDR was essentially non-ideological. There was an imperative to do something, really to do a bunch of things. But what those things should be and what grand idea would give coherence to the lot of them, that was a different matter. Roosevelt didn’t have that grand idea. Instead, he had a sense of experimentation. Try a program. If it worked, keep it. If it didn’t, get rid of it and try something else. This was Pragmatism but without the trappings, certainly not the Liberalism we associate with FDR today. Roosevelt brought in a Brain Trust of Washington outsiders. They constructed the programs. They defined Liberalism, but really that was a consequence, not a prime cause. Unemployment was over 25%. Hoover’s economic orthodoxy proved toxic. Something else clearly was needed.

Nowadays we seem in the habit of putting politicians into political boxes – Republicans in the Conservative box and Democrats in the Liberal container, the folks in one box with vitriol for their rivals in the other. William Kristol in his last column for the NY Times, treading gingerly as he can, nonetheless can’t avoid casting the Obama Presidency as a new test for Liberalism, whether it can claim the future. Why is this a helpful lens with which to consider the Obama White House? If his regime does something unpredictable, does that mean Liberalism is moving in a new direction? What possible benefit is there in labeling such new policy as Liberal except to create a visceral negative reaction to it from Conservatives. In a similar fashion, Paul Krugman in his analysis of Republican opposition to the fiscal stimulus package, castigates the Conservatives for being obstructionist. He doesn’t venture to try and see it from their point of view. But if pressed Krugman would be forced to admit that government programs initiated to jump start a sputtering economy have a tendency to remain in place well after the economy is on the road to recovery, when the stimulus is no longer needed. Then aren’t we implicitly having a long run argument about the appropriate amount of Federal Government spending while we’re working through the stimulus package? If so, shouldn’t there be some critique of the program based on purely long term views? Putting the opposition into a box blocks the argument when we should be encouraging it.

Sometimes I wonder if I believe in my own writing and when that happens I try to test what I’ve said. After completing the previous paragraph I did a Google search on “the benefits of ideology.” Midway down the first page of hits I found this recent piece by John Santore from The Huffington Post which, in turn, references this piece by Christopher Hayes from The Nation. Both are worth reading on this topic. We need values on which to base decisions and to determine whether outcomes are good, even if otherwise we claim to be pragmatic. In toto those values constitute an ideology. I agree. And sometimes deeply held ideology serves are as an appropriate counterweight to bereft ideas and morally bankrupt policies. That too is true. But I don't think it enough and I don't believe it fully explains away pragmatism as Obama (and FDR) intended to use it.

As a rule most of us don't fully articulate the set of principles that make up our core beliefs. Even if we do, such an articulation is not a commitment. When a real situation arises where the principle applies and we understand that it does apply, our behavior serves to test the principle. Sometimes belief in the principle drives the behavior. Other times not and what we may discover is, in fact, the belief is in a somewhat narrower principle. We may say, for example, we believe in some of The Ten Commandments, particularly, "Thou shall not steal." But we may cheat on our income taxes nonetheless. How can that be reconciled? Perhaps with a response like, "There is no harm." The narrower principle then is, If there is an obvious victim then thou shall not steal, but if there is no apparent victim then go ahead and worry only about the chance of getting caught, not the moral imperative.

Because we don't fully articulate our principles we may find a different issue in practice. Two or more of our principles may be in apparent contradiction or may suggest opposite forms of behavior. We are forced to rank order the principles so one may trump the other and lead to a clear decision. But we may surprise ourselves in that ordering and find it depends on experience, not on prior disposition. In Carl Sagan's book Contact, the space travelers (in the movie there was only one, the character played by Jodie Foster, but in the book there were several) have no evidence whatsoever of their trip through a series of wormhole "tunnels" to Vega and other points galactic, so though atheists themselves and people whose deepest beliefs are founded in science, they nonetheless feel impelled to ask others simply to trust them on their word in spite of the lack of evidence. Sagan has constructed a delicious irony which is why Contact is such a good story. The extraordinary experience and power of that experience trumps the prior held belief in all things science.

Then too there is the possibility that our principles are insufficient to determine a course of action and to judge whether outcomes are good or not. As an adult watching a parent or a parent-in-law go through progressive deterioration due to the onset of dementia, the inability of the parent to see reality and cope with it trumps any sense of rightness in the decisions on how to manage the parent's care. Expediency, not normally a fundamental principle, ends up the driver.

Let me make one other point on this topic, a point that Santore and Hayes would subscribe to. It is different to say that we each base our decisions and evaluate outcomes on the basis of an ideology than to argue that there are a small finite number of ideologies (conservative or liberal) within which our beliefs must lie. If there is substantial diversity of such ideologies but we are nonetheless to get along then compromise becomes an ordinary practice. It is well known that there is no equivalent to Duncan Black's Theorem about the Median Voter when there is more than a single dimension (left-right) where voters can express their preference which can lead to instability in outcomes or to manipulation by a Machiavellian Prince (or a Committee Chair) that others would deem unfair. A willingness to compromise, in this sense, can be seen as a commitment not just to get things done but also to a commitment in fairness of the process. I believe that is a value which many if not all people subscribe to. It also means that one wants to look at outcomes over time, not just at a single incident, and see if those outcomes "average out" in some rough way and as a whole trump the gridlock that opposing rigid ideologies often produce, but with that criteria it also makes sense that what looks like absolutely disasterous decisions should be blocked ratherthan negotiated to fruition, because the ill consequences will never average out with other more successful outcomes..

The quintessential decision in this regard is the Iraq War. The problem is not that no WMD were present and hence that we should not have gone in at all. The main question is whether we should have anticipated Civil War soon after liberation, a repeat of Yugoslovia after Tito, and then as a consequence the U.S. Military involvement would extend for upward of six years. If so, then the pragmatic approach would be to argue for staying out. This would not be an ideological decision. It would be a straight cost-benefit analysis. Jeanne Kirkpatrick,certainly nobody's idea of a dove, publicly embraced but privately was against the War for these very reasons.

I fear we face the same sort of tyranny with ideology in teaching and learning. The (mis) perception is that there is one right way to teach, one right way to design student assignments, one right way to assess that work. Think of all the jargon we now have to describe effective practices: student centric, active learning, authentic assessment. Instructors are either in this camp in which case students are the heroes and lecture is the enemy, with the characterization of the enemy approach particularly demonizing, or instructors have not yet found salvation and teach in a fairly traditional manner with no obvious way to implement modest but continual improvement. A Roosevelt-like approach to the situation should be welcome, but there is no way to fit it into this setting.

I want to describe a non-ideological view of the circumstances so we can frame how an experimental approach to improving teaching might proceed. Let's start with the student-teacher divide. Both Arthur Levine, in his chapter of the book Declining By Degrees, and Russel Durst in his book Collision Course, assert there is a substantive student-teacher divide. In the main students are extrenely practical about their learning and want to put what they are taught to good use. In contrast, Faculty are just as extremely theoretical about their teaching. Next, let's consider learner motivation. There is no doubt that "learner control" is empowering to the learner, first and foremost due to intrinsic motivation in the subject, then even with extrinsic reward as long as the reward is constructed in a way to encourage the learner's own autonomy. (See Ryan and Deci.) Then consider the effectiveness of the learning. Students have been socialized to study subjects as things in themselves, but experts believe it better to measure how students apply what they learn to new contexts. This is termed transfer. Transfer is facilitated by a theoretical approach to instruction since theory is generalizeable and hence applied in other contexts. A more nuts and bults approach might improve student understanding of the ideas themselves, but makes transfer more difficult because students don't see how to apply what they've learned. Last let's consider was is known about expert knowledge. Experts don't do "more thinking" than their novice counterparts. Rather they do better thinking. They have much better pattern recognition. They know what to look for to solve a problem in their area of expertise so can arrive at a satisfactory solution much more quickly. The develop their expertise via Effortful Study over a long period of time, perhaps 10 years of work, four hours per day each and every day in those 10 years. If learning is moving down the path toward expertise then students require challenges that are just out of their reach and they need to put in the time to meet those challenges.

All of this is pretty much agreed upon. There is no real dispute in each of those four components of the view. Put them together, however, and throw in for good measure that class size limits the amount of one-on-one interaction between student and teacher that is possible and the result is inherent tension - who drives, theoretical or practical orientation to the study, how much time does the student put in outside of class, how is the student tested? Based on what we know the answers should be idiosyncratic to the student, the subject matter, and the instructor's style. Yet such customization in approach is hard to achieve. Reality of limited resources forces things to be closer to one-size-fits all. The doctrinaire ideologically driven arguments on how we should teach ignore some aspects of this environment. A Roosevelt-like experiment would focus on one of those aspects by changing matters there and hope that it does no harm in the other dimensions, judging the overall result for whether it is a step forward or back. Such an experiment can be conceived only by an insider, the instructor who is familiar with how the course is going at present. Outsiders can be used for consultation, certainly. But they shouldn't drive because they can't directly test appropriateness and therefore can't see the wisdom (or lack) in what they recommend. Unfortunately, we don't seem to witness much of this sort of experimentation.

Instead, the prescriptive approach to faculty development seems ever with us. It's not just the pundits who put people into boxes.

Getting Rid of the Blur

The following Tip is from the Jing Pro site
Tip: YouTube displays low-quality video by default; if you want your viewer to see high-quality video, add &fmt=18 to the end of the URL when you send it to them.
Likewise, here is a link to explain how to get the higher quality in an embedded video. The video below is the same one I had embedded in the Google Presentation yesterday, but it is a lot sharper in view.

Blip.tv does this without all all the bother. But I know some folks don't want to put video content elsewhere than YouTube for fear that the provider will go under. Those fears might be self-fulfilling.

Presentations in Google Docs with YouTube Video

Here is a little example of a PowerPoint presentation with YouTube video embedded on each slide. You need to use your Google Account to access the thing properly, but it should be generally available.

Slides one and three have talking head video. It doesn't autostart. There are buttons for both video play and for slide navigation. But otherwise, I think that is pretty good.

Slide two has screen capture video. YouTube blurs that video. I wish I knew how to solve the problem. (I assume it blurs the talking head too, but the consequence is less to the viewer.) Here is the same video rendered clearly.

Slide three also has a link to a Form from a Google Spreadsheet. This is to show that a type of assessment can be tied to the presentation. Of course, there is essentially no security with this. The form is publicly available., as is the rest of the presentation. But in terms of ease of use and low cost (Google Hosts it all) this seems like an interesting alternative.

A Rhyme About Higher Ed

I wrote the rhyme in response to this piece from yesterday's Chronicle, which upset me. With apologies to my readers, because it is not elevating.

* * * * *
Higher Ed looks to be in big trouble,
From burst of the housing market bubble.

There’s a mad scramble for revenue and to reduce cost.
Some already feel all has been lost.

Others think modest cuts will suffice.
Underestimating problems has long been their vice.

Few have looked to reexamine the mission.
It’s far easier to consider raising tuition.

That would reduce access to those of modest means.
College no longer promotes upward mobility, or so it seems.

The issues have been with us for more years than twenty,
Student engagement, Campus commitment, and others, of which there are plenty.

Part of the trouble is rising income inequality in the larger society,
Causing wasteful inter campus competition beyond all sense of propriety.

Superstar faculty first come and then go.
So ambitious department heads can put on a show.

The movement of the stars cast a large net.
The rest of the faculty want to know what they will get.

The resulting dynamic creates constant hunger for new money,
Although this vicious cycle now no longer seems funny.

New research areas arise from discovery and need,
Creating new Centers and buildings at alarming speed.

While traditional programs keep on going,
Though their prestige and income is necessarily slowing.

The students too are culpable I fear,
It goes way beyond their drinking too much beer.

They’re jaded, incurious, and work not enough.
It’s not that the courses they take are too tough.

They go to college for the sheepskin rather than to learn,
For after all it’s well paying jobs that they yearn.

For freedom from responsibility college is one last gasp,
Before they graduate and enter into the rat race grasp.

All this has been happening for a while let’s be clear.
It’s not that it just started this year.

Though it finally seems that the dam has been burst.
Making the current situation feel like the worst.

Something surely true, though it seems strange.
Crisis affords the best opportunity for real change.

It alters our perspective about what we care,
Encouraging us to take the intelligent dare.

To demand more from all participants is a must.
That’s the only way to reestablish the trust.

Beyond that the entire system must reform.
Unilateral action by individual campuses will only worsen the storm.

But first we’ll think near term and so we will flail,
Only realizing later it was all to no avail.

Then we’ll finally be ready to ask,
Which really should be our fundamental task,

What would an effective system look like and how would it behave?
If we knew that surely it should be the road that we pave.

Until we ask those questions watch out for Higher Ed.
For if that doesn’t happen soon it might end up dead.

Project for the New Year

I've started to write a book. It's called Guessing Games. I'm putting up drafts at this site. The first few chapters are there as is the preliminary content. You can also see some of the remaining structure planned. Not there at present is a practical implementation plan. If after reading some of this you have ideas for the implementation plan, I'd love to hear them. I'd also be delighted to receive comments or suggestions on what is there.

I'm likely to be posting less to this blog while doing the book but I will put update announcements here when I have new chapters, and I will continue to make posts that are about the technology per se.

Doing this book is my New Year's resolution. Let's see if I can keep it.
