Piazza Discussion Boards Get an A

Piazza Discussion Boards Get an A

I tried a lot of new things in my class this semester, and now that it’s over, it’s time to take stock of what worked and what didn’t. This fall my students posted 492 questions to our Piazza online discussion board. I answered 385 of them and contributed another 173 follow-up responses. It was a fair amount of work, but it meant everyone could read my answers and almost no one felt the need to come to my office hours. I missed the personal connections you make during office hours, but this system was a far more efficient use of everyone’s time.

Student Anonymity

Student Anonymity

One of the most successful parts of my class this fall (Econometrics with about 150 students) was the Piazza online discussion board. I’ll be writing more about Piazza soon as I systematically document the huge amount I’ve learned teaching during the semester, but today I want to focus on one aspect of Piazza. By default, Piazza allows students to post questions anonymously. Their fellow students don’t know who they are and neither do I. This sometimes led to mildly annoying posts like these:

Do Girls Try Harder or Work Smarter?

Do Girls Try Harder or Work Smarter?

The other day a friend told me that male students outnumber female students two to one in Harvard economics classes, but that the women don’t realize it because the students who show up for lecture are about evenly split. I asked one of my students what she thought was going on. She looked at me funny and said “Girls are Try Hards—Of course they go to lecture more than boys. They spend more time on problem sets and papers and studying for exams too.” Then it occurred to me that I’ve got data—I could see if this really true, at least in my class. What I found was surprising.

Lecture Attendance: Who Comes, Why They Come, and What It All Means

Lecture Attendance: Who Comes, Why They Come, and What It All Means

Students at Yale feel no obligation to attend lecture. They often tell me that if they aren’t getting anything out of lecture, they’ll just stop going. As an economist, the idea that students are simply making a rational choice appeals to me. As a professor who currently sees about half his students coming to lecture, I find it somewhat distressing.

Balancing Research and Teaching at an Elite University

Balancing Research and Teaching at an Elite University

A few weeks ago a reporter for the Yale Herald (“Yale’s most daring publication since 1986”) interviewed me about teaching at Yale. We had a long pleasant talk, and the resulting article was just published. Many faculty are quoted, but it seems I was willing to say the most extreme things and thus got fairly high billing. I don’t (yet) regret anything I said, but I do want to flesh out a few points.

Homework and Potty Math

Homework and Potty Math

I was talking another parent the other day and she mentioned that her first grader gets homework every night. I was a little jealous because, believe it or not, I have fond memories of homework in elementary school. My older daughter’s school believes in kids working hard during the school day and then having fun and decompressing afterward, and they rarely assign homework.
