Note. Forest plot showing effect sizes from stratified matching analyses. Numbers below each course name indicate the number of students in that analysis (and as a percentage of the total class).

Right: Effect of “dropping” the Exam Playbook. Both groups used the Exam Playbook for Exam 1; students who dropped the Exam Playbook at Exam 2 did worse than students who consistently used it. Error bars reflect 95% confidence intervals.
