Iclickers and student performance

We ask if students using the iclicker classroom response system to answer graded questions perform better on exams than students asked the same ungraded questions without the iclicker. Students using iclickers averaged 3–4 percentage points higher and had a higher proportion of grades in the range B+ to A. However, based on the sample of students who allowed us to access their academic records, the differences are not significant controlling for academic and demographic variables.
