  1. All students received credit for completing the GeDI pretest; in some courses, students received credit for completing the posttest, while others were scored based on correctness. The GeDI was embedded in the lab activity as both a pre- and post-test. The pre- and posttests were administered within a 2-week period for all of these courses.
