Group research projects frequently are used to teach undergraduate research methods. This study uses multivariate analyses to examine the characteristics of higher-achieving groups (those that earn higher grades on group research projects) and to estimate the effects of participating in higher-achieving groups on subsequent individual learning (grade on final paper). The sample includes 257 students who completed a sociology research methods course at a small liberal arts institution between 2004 and 2015. Group achievement (grade on group research project) is predicted by group size, gender composition of the group, and group's average grade on midterm exams. Group achievement on the research project contributes to subsequent individual learning (grade on final paper) even after controlling for individual characteristics (student's gender, race, and average grade on midterm exams) and group characteristics. The findings support claims that group research projects are an effective pedagogy for undergraduate sociology research methods courses and point to some guidelines for instructors' composition of groups for research projects.
