Second Assignment for this Week’s TLT Fellows Meeting

The second thing we were asked to do for this week’s meeting was to identify a couple of bloggers from our disciplines.

I can recommend four blogs:

1. Grasping Reality With Both Hands: Brad DeLong’s Semi-Daily Journal – Very high brow blog, world-class, Berkeley economist, writes about serious policy issues, sometimes ten pages worth per day.

2. Greg Mankiw’s Blog: Random Observations for Students of Economics – Another world-class economist, this one is from Harvard. Mankiw’s blog takes a more conversational tone, and seems to be a sophisticated ancillary to his very popular introductory economics text.

3. Marginal Revolution by Tyler Cowen and Alex Tabarrak. Both authors are from George Mason University. Among the first economic bloggers, and widely read as is evident by the number of ads the blog includes, Marginal Revolution is semi-high brow, focusing on political economy.

4. My personal favorite is Market Power: Selected Musings By an Academic Economist on the Power of Markets by Phil Miller.
Miller, from Minnesota State University, Mankato is, for lack of a better descriptor, a ordinary economist like most of the rest of us, which is part of what makes his posts interesting.

TLT Fellows Projects

I have the privilege this year of participating on our school’s Teaching and Learning Technology Fellows program, a faculty development program for instructors interested in incorporating instructional technology into their teaching. Participants meet weekly for a semester and explore IT tools under the guidance of our instructional technology staff and a reference librarian. The ratio of experts to learners is slightly more than one to one. Martha discusses the TLT Fellows program in a recent post here. The goal of this semester’s meetings is to develop a project that we will implement in one of our courses next semester under the guidance of an Instructional Technology Specialist whose interests and expertise most closely match the needs of our project.

For most of this semester, I have had no idea what my project would be. But within the last week or so, I have found a plethora of ideas, four to be exact. The purpose of this post is to summarize my thinking on those ideas (in no particular order) and hopefully generate some useful feedback from you.

The first project is to construct and use a ‘bliki’ for my advanced macro seminar next Spring. A bliki is a mashup of a blog and a wiki, combining the best features of both. This project has special meaning for me since the last time I taught this seminar, three years ago, was when I first started incorporating social software into my courses. Wikis are excellent for collaborative work, but the knock on them is that they are not ‘pretty’. Fair enough, but that’s like complaining that a snow plow isn’t pretty. Why should you care as long as it digs you out of the snow? The look of a wiki doesn’t really matter for process-oriented work, but one thing I’ve been attempting in the last two years is to turn the work from process to product. In other words, student group work is creating content for subsequent students to use as a resource. We’ve used the wiki as a whiteboard for our ideas during the semester, but then for a final project I’ve asked the students to convert what we’ve done in the process of our learning to a more polished product. So far, this has been only partially successful. I’m hoping that a bliki will give the product more of a professional look. I remember a blog post that Jim wrote, suggesting that Andy might be the expert here.

My second project idea is based on Patrick‘s comment at a recent TLT Fellows meeting that there are a number of interesting looking applications out there that go beyond blogs and wikis. I’d like to explore some of these and think about how they might be productively applied to teaching and learning.

My third project idea is to explore the notion of an ePortfolio. This was Sarah‘s idea and I’d like to work with her on it. What is an ePortfolio? What features would it have? How would an ePortfolio for an English major differ from one for an economics major? Whatever software we come up with probably needs to be general enough that it can be customized in whichever direction the instructor wants to go–It should be somewhat plug and play. This argues for an open source, small pieces loosely joined approach. Furthermore, an ePortfolio should probably have a very different look from the perspective of a student who’s uploading the content, and a faculty or department who is using the content for outcomes assessment.

The fourth idea involves my throwing down the gauntlet to Jim: Can video be used in a pedagogically sound way to teach economics? I have dabbled in video over the last year or so, using snippets to illustrate a point in lecture, or using something from youtube as a source of course content. I suspect though that video could also be used as a medium for creative thought. But is it something useful for teaching/learning economics? That’s not clear to me yet.

I also have a fifth idea which qualifies only as Web 0.5. I would like to know how to create graphs to illustrate economics arguments that you can see in any economics textbook. I ought to know how to do this, but I don’t so the next time anyone accuses me of being ‘on the frontier’ of IT, they should remember this. 😉

AAUP and the Future of Higher Education

I had the opportunity this week of attending a lunch discussion with Ernie Benjamin, Interim General Secretary of the American Association of University Professors. The session was very informal, with faculty coming and going as needed while Dr. Benjamin discussed several issues. He did not have an opportunity to give a formal presentation.

All that said, I was somewhat disappointed. The session was billed as an opportunity to hear AAUP perspectives on academic freedom and the future of higher education. At the risk of over simplifying (always a problem for me), here is what Dr. Benjamin said. The proportion of full-time, tenure or tenure-track faculty is down significantly over what it has been in the past. More and more faculty are ‘contingent’ in nature. This poses a threat to academic freedom and thus weakens the quality of higher education. The accountability movement in higher education threatens to dumb down the curriculum to that which is easily measurable, as has occurred in K12 education as a result of No Child Left Behind. Serious quantitative measures to assess educational effectiveness have been generally co-opted by unsophisticated audiences and reduced to comparing raw scores un-controlled for differences in institutions. University authorities have deflected measures to increase transparency about their programs and staffing, which would make it easier to genuinely evaluate different schools’ programs.

While I agreed with nearly everything Dr. Benjamin said, it struck me that his comments were almost completely defensive in nature (and highly conservative in the original sense of the term). Benjamin stated that higher education in the US is the best in the world, and thus implicitly, there is nothing to be done to improve it except to restore the balance in tenure/tenure-track faculty. In particular, he said nothing about potential changes in way teaching and learning in higher education may occur in the 21st Century. Is University 2.0 too avant garde for the mainstream? Or is the AAUP’s focus too narrow to consider that possibility.

It’s not just semantics

I returned the first exam in my intro course the other day. The average grade was a bit lower than normal. I wonder if that reflects the somewhat higher than normal number of first year students in it.

I did the return a bit differently this year. Usually, I hand back the exam and spend the class going over the questions. The mood is somber and the attention questionable. This year, I gave back the exams at the end of a class lecture, and asked students to look over theirs and try to figure out what they did wrong. (The exams are multiple choice; the correct answers are provided on the corrected answer sheets.) My thinking was that rather than my doing the processing of results for them, I would ask them to do it. As a final step, I asked them to email me the numbers of any questions they couldn’t figure out on their own (or otherwise wanted me to go over). I collated those choices and we will go over them in class today. We won’t waste class time on questions everyone answered correctly or on those where students made simple mistakes. Additionally, the students should be no longer in the trauma of just receiving a poor grade.

For the first years, this was the first time many had ever received a ‘poor grade’ on an exam. In some cases, this poor grade was a C. I’m not making fun of this reaction–these students have performed well in high school and see themselves as good students. But as I noted previously, the rules are different in university. Because of the larger than normal number of first years this time, I’ve thought more carefully about how they react to this.

I think there are faculty who see the rules of higher education as not much different than in high school, just with higher standards. Students who were successful in (e.g.) science in high school, don’t do as well in college, and this simply represents a winnowing of the field when the bar is higher. Survival of the fittest. Those students likely will find another discipline which better matches their talents and abilities.

There is no doubt some truth to this view, but over time I’ve come to subscribe to a different one. The rules of higher education are substantially different and not merely, or perhaps even primarily, the higher standards of competence. Learning is far more than grades. Grades are at best a rough indicator of learning. Over the years, most of my best students were not the students who got the best grades, at least in the lower level courses. Rather, they were the ones who had to struggle with the material. Strangely we tend not to test on the most important parts of learning. In part that’s because it’s difficult. Assessing factual knowledge is much easier than assessing critical thinking ability. Over time, I’ve tried to re-align my assessment to match my assessment with the more important parts of teaching and learning, but it remains imperfect. It seems to work best in less structured formats where I can ask students to ‘show me what you’ve learned,’ rather than asking every student to answer the same questions.

What I try to teach my students is an understanding of how to do economics, as well as an appreciation for the power of the economic way of thinking. Writing the previous sentence seems almost to trivialize the two goals. Both goals are richer than the words suggest. In high school, I think most teaching is about a discipline. In university, we should be teaching how disciplinary practitioners practice their arts and sciences. I see a fundamental difference there. When students see an application of economics in the real world, I want them to be able to analyze the situation the way an economist would, even without the complexity or deep understanding that a professional has. When I talk about the appreciation for the power of economic thinking, I mean something like what an art or literary critic brings to the table though at a lower level.

These are achievable goals for my undergraduates and they don’t correspond necessarily to the normal structure of grades. Indeed, in some ways, the grade structure is orthagonal to what I’m trying to accomplish. In 25 years of teaching, I’ve only had two or three students who I concluded were unable to learn what I was trying to teach. (That doesn’t mean only a few students didn’t learn, just that only a few were unable to.)

When I discuss the exam today, these are some of the things I will say. Unlike the view of higher education laid out in the fourth paragraph above, I believe that all students can achieve a level of competency in what I’m teaching. Getting a failing grade on an exam doesn’t mean one is unable to learn the subject. It just means one hasn’t figured out how to learn it yet. This is not just semantics. There are different ways of learning, and different faculties to tap into. This lesson is particularly important for first year students who may not have study skills or habits amenable to higher education. A student who appears attentive in class and yet did less well on the exam than I expected said to me yesterday:

You mentioned that staying up all night before the exam to study wasn’t good practice. Were you serious? That’s the way I’ve always studied.

I am confident she can learn a different way, one which relies less on absolute talent, and more on more thoughtful uses of the talent one has, one in which she can learn economics effectively.

Journalists on Social Networking Software

There were two articles published last week in popular media on social networking software:

The Wall Street Journal: More, but not Merrier: Web sites that help you collect and ‘manage’ friends. (HT to Dave Moore)

The Washington Post: With Friends Like These

Neither is particularly sympathetic. I am not disputing that people with hundreds of “friends” online can hardly be participating in deep relationships with all. Also, I am only a very casual user of FaceBook, so I can’t be considered an authority, but what both articles seem to ignore is that people who have friends in real life use social networking sites to keep in touch online.

The grade’s the thing

Between my first year seminar and two intro courses, I am teaching a lot of freshmen this semester. I really enjoy freshmen. They are fresh; they generally do what you ask of them (e.g. readings), and they show more progress in a course than the upper level students do. But this term I really feel a sense that they haven’t ‘gotten’ what higher education is about yet, as if they haven’t recognized that college has a different set of rules than what they are used to.

When I was a third-year undergraduate, economics began to make sense to me. Before that, I found it fascinating, but it wasn’t until the third year that it began to come together for me. I really felt that if I had another year or two to study, I could really master the subject. And so I went to graduate school. What a surprise that was. The more I learned, the less I knew. The more I studied graduate economics, the more I realized its complexities and how little I really knew about it. Mastering the subject is a life’s work, and even then one is never done. Mastering an academic subject is not a discrete skill, like learning to ride a bike, where once you’ve figured it out, you know you’re done.

Lately, I’ve been struck by how different the views of my freshmen are, at least most of them, from that expressed in the previous paragraph. What’s striking to me is that, for the most part, these are good kids, students who performed well in high school and who want to do well in college. And yet they’re still trying to play according to the old set of rules, from high school.

K started the conversation two weeks ago saying, “I don’t know how I’m doing in this class (The FSEM). Am I doing okay?” Fair enough; this is the course where I give formative feedback but no grades per se until the end of the semester. So K’s comments, prompted me to have a discussion about grades and learning in the course. One question we discussed was whether grades should be based on knowledge or learning. Knowledge is what you know including what you may have brought to the course, while learning is what you’ve added to your knowledge from the course. Interestingly, the students argued that a skills-based course, like music or art, should be graded on learning, while a content-based course, on knowledge. I’m not sure I agree, but the result of our discussion was that I told students that if they really wanted to know how they were doing in the course I would be happy to talk to them individually, but that I haven’t really considered any of their work yet in the context of grades. They seemed puzzled by this revelation as if to say, what context is there for learning other than grades? So far, I haven’t had any takers.

This summer, when I was ruminating about assessment in my intro courses, I decided to put less weight on the exams, and more weight on a collection of homework activities. My intent was to build more opportunities for low-stakes self-assessment into the course. As part of the homework, I included two sets of self-assessment activities for the students, a low level assessment which essentially helps students determine if they’re learning enough to pass, and a high level assessment which examines their likelihood of deeper learning (and presumably a higher grade).

Earlier this week, I handed back the first formal paper in the intro course. This is one of probably half a dozen assignments which collectively are worth about 15% of the course grade. So this paper was worth no more than 3%. Since it was the first formal paper I assumed that students wouldn’t necessarily know what I was looking for, so I didn’t give any grade less than a C-. There were a handful of A’s, about half the rest B’s and the other have C’s.

M1 (by all accounts a serious student) began freaking out about receiving a C+ on the paper. “I can’t get a bad grade,” was what she managed to say. M2 (another student) picked up the thread: “You don’t understand. My parents will kill me if I get a bad grade.” While I was not unsympathetic, I saw myself and the grades as contributing to the opening round of a conversation that will continue all semester, if not for the duration of the college careers. At this point, E (a sophomore), addressed the freshmen saying, “Oh, it’s different in college.” Exactly.

I began to think about the self-assessment activities. The online quizzes (the low-level assessment) yield a percentage score, which the students understand, but the quiz questions are very simple so they aren’t a very good test of the material. The meta activities (the high-level assessments) are abstract and complex and the direct feedback they provide is subtle. There’s no letter grade, so understanding how to complete them and understand the feedback takes time and reflection–Like playing a song well on an instrument. Most intro students don’t seem to have the patience for this.

Grades are only a rough indicator of what students are learning. I mentioned that in my intermediate theory course, the mean grade on the midterm exam is usually about 55%, but that’s not a sign of failure, rather it’s 55% of what a Ph.D. economist would know. Of course, I curve the grades for my students. L, a student in the intro course queried, “If the average is only 55 on the midterm, maybe you should make the course easier.” What does it mean to make a course easier? If I’m trying to learn Mandarin, can I make the language easier? Certainly I could make the test easier, but that would simply raise the mean grade. It wouldn’t mean the students had learned more. Macroeconomics is complex and difficult to master. I think the exams signal that. Even the best students see that they could do better, always. That’s the way macroeconomics, and probably most disciplines are in the real world.

One more anecdote from the intro course. A student told me this week that he thought he had fallen behind and asked to make an appointment with me. This student has missed a noticeable amount of class time and hasn’t turned in any of the assignments so far (one formal paper and several assessment assignments). When we met, he told me that he hadn’t read (all?) the chapters in the text, but then added “sometimes I surprise myself on exams and manage to pull out a good grade.” What would that even mean in terms of his learning. When he turned in his midterm today, he mentioned that he’d read some of the chapters, and was hoping for the best.

UMWBlogs, Baby; They’re taking over!

I was reading the first metacognitive activity submitted by students in my intro course, prior to discussing it tomorrow. (I’ve decided to move that discussion outside of class time to avoid the potential problems I ran into last year. I’m meeting with any student who turned in the meta after my last class, the meta being the entry fee.)

So I opened the next student’s email containing, I supposed, their meta. I was pleasantly surprised to read:

Hey Dr. Greenlaw,

I have my first Meta complete now. It’s in the form of a UMWblog, and all the other Meta assignments will be posted on the blog.

http://dmoore201b.umwblogs.org/

Enjoy,

I opened the link in my browser and discovered an incredibly creative and thoughtful submission, which I commend to your review.

What was particularly interesting about this was that I haven’t said a thing about blogs this semester, other than to build the course website on a WordPress platform. So the students aren’t supposed to be blogging for me. This student just decided to do it anyway. Fascinating!

Quick note on teaching my intro course

One of the ideas I explored this summer was the finding that students bring misconceptions into a course that need to be explicitly refuted if learning is to be transferable. It turns out that there is not that much known about what these misconceptions are in economics. What I plan to do this term is start each new topic with a question that illustrates a possible misconception. For example, for the topic we began yesterday (The Theories of Supply and Demand), I posed the following question:

An increase in the price of a product leads to a decrease in the amount people buy (what economists call ‘the quantity demanded’). But an increase in demand for a product leads to an increase in the price.

Is this a paradox?

Before the end of the topic, I’ll make an explicit effort to show students how that question should be answered.

I also plan to pay careful attention to what the students are learning and having trouble learning this semester so that I’ll have a better idea next time what the misconceptions are.

A Challenging Student, in more ways than one

I have a challenging student in my intro course this semester. In twenty-five years of teaching, I’ve never had a student quite like this one. He appears bright. The first week, he spoke up regularly in class. Since then he has become increasingly beligerent.

On the first day of class, I asked the students to define economics in their own words. I wrote a sample of definitions on the board and grouped them by themes. Next I proposed examples that the group agreed were relevant to economics but that were inconsistent with a given definition. For example, to challenge the definition of economics as the study of money, I suggested Robinson Crusoe. Economics was clearly relevant to his situation, despite the lack of any money. My purpose here was to expose to students their mistaken views of what the discipline was about. The recent literature on cognition suggestions that failure to refute mistaken preconceptions limits transfer of learning.

Last week, I offered my definition of ‘theory’ to which the student interjected “Well, you’ve spent the last week trashing our ideas; it seems only fair that we should be allowed to criticize yours!” While thinking that he seemed to be overreacting, I told him that I welcomed criticism.

Yesterday as always, I began class by asking for any questions. The student stood up and said, “I want to tell you that I’m very disappointed in this course so far. It’s been over two weeks, and I feel like I haven’t learned anything.” The class seemed shocked, and I replied that I was sorry to hear that, but that there was much to come in the course. At that point, another student stood up and said, “I took Greenlaw’s micro course last Spring, and I found it very interesting.” Yet another stood up and said, “I think this course is very interesting, too.” I moved the discussion back to the topic of the day, but couldn’t help continuing to think about the student and his comments.

Is it possible that he’s learned nothing from the readings or the class discussion? If so, I think I should suggest additional readings to push his learning further. Or is it perhaps that he’s one of those students who wants everything to be tested spelled out explicitly so he knows what to memorize for the exams? I will know more after the first assignment at the end of the week.

Even if he hasn’t learned anything, what do I make of his public challenges? What does he think he’s trying to accomplish that he couldn’t achieve with a private conversation or email? The rest of the class seems to think he’s an idiot.

I plan to talk to him privately and ask these questions. Can you suggest anything that might shed light on this situation beforehand?
