The Efficacy of Collaborative Learning Recitation Sessions on Student Outcomes

We investigate the efficacy of Collaborative Learning Recitation Sessions on Students Outcome. A quasi-randomized experiment is conducted on two large introductory microeconomics class sections at Indiana University’s Bloomington-Indiana campus in the Fall 2009 semester. Program evaluation methods are used to compute the treatment effect of students participating in Collaborative Learning. We find an average treatment effect in the range of 4.6 to 4.9 percent on the raw final grade. This translates to a grade change i.e., B to B plus.
