My colleague, Lolita Paff, has been exploring student attitudes and beliefs about participation. Most of her beginning economics and accounting students describe themselves as “limited” or “non-participants.” They say they don’t participate because they don’t want to look foolish in front of their peers or they learn better by listening. At this point, she has gathered some rather compelling data that grading isn’t motivating her students to participate more. “I had been pretty strongly in the if-you-grade-it-they-will-do-it camp. The evidence surprised me and made me rethink grading participation,” she writes.
