Comment by Jean Maines: Greetings fellow pulsers. Quick question--do you know the approximate % of students who pass (a-c) freshman biology for science majors at your institution? Anyone know where to find this data nationally?Thanks for any help you can provide! Jean
Jean, this IS an essential question! At my institution, my intro Bio class, "Introduction to Metabolism, Genes, and Development," used to have a C- or below fraction of ~35%. Since using a cinematic lecture/active learning (CLIC) model of flipping, this has improved to ~10%. Grades are determined by 7 10 point quizzes, 3 mid-term exams, and a final exam. Grades are curved, with class mean ~ B-, and standard deviation units used to establish grade ranges. The class means have increased, and the variance has decreased, with a pronounced diminishing of the bimodal distributions I used to get. It took a few semesters of developing active learning modules to accomplish this, and the process continues, but the results have been dramatic!
If you find national figures, could you post them here?
