Do Graphs Promote Learning in Principles of Economics?
) (University of South Carolina) Sharon Cohn Donald C. Balch (University of South Carolina) James Bradley, Jr. (University of South Carolina) Abstract The authors tested whether student performance in the principles of economics course is affected by the use of graphs as part of a lecture. They conducted two experiments at the University of South Carolina, one in spring 1995 and another in spring 1997. Students were randomly assigned to either a nographs lecture or a lecture with graphs. The main hypothesis was that students in the lectures with graphs would show higher gain scores than those in the nograph lectures (both lectures were videotaped). The authors found that students in the lecture with graphs in 1995 had significantly lower gain scores than those in the no-graphs lecture. For 1997, they found no significant differences in student performance between the two groups.
