Effect of adding study session during class time
Students do poorly on exam 1. Students participated in a study activity during one class period one week before exam 1. The activity emphasized novel presentation of material (puzzle), repetition, additional study time, interaction with other students and the instructor. The material studied accounted for about 50% of the first exam. Averages of the exam 1 did not differ from averages of 7 previous classes, but grades of A and B almost doubled in the activity group.
