In Spring 2013 MATH 1271 Lec 030 (my lecture section), I taught by "flipping the classroom", a teaching technique in which lectures are viewed on video outside of class while skill-training is done in class. That semester, 178 of my (Lec 030) students took the final exam. Including all the lecture sections, 504 students took the final exam. ---------------------------------------------------------------------- Summary The first column is a grade range. The second column is the percentage of students in Lec 030 whose final exam letter grade is in that range. The third column is the percentage of students in all lecture sections whose final exam letter grade is in that range. Lec 030 All ------- ------ A- or above 18.54% 14.88% B- or above 43.82% 39.29% C- or above 75.84% 74.21% D or above 92.70% 92.46% There seems to be improvement in the "A- or above" and "B- or above" ranges, possibly, in part, because of the unusual teaching technique (flipping the classroom, mentioned above). The other numbers are close. So, that semester, it appears that the top students benefited, but that the effect was not as strong for the rest. ---------------------------------------------------------------------- Students in good standing In 22 lectures and 11 recitations, a single quiz was given. In one lecture, 2 quizzes were given. Let's define a student to be "in good standing" if he/she received a nonzero score on at least 32 of those 22 + 11 + 2 = 35 quizzes. In Lec 030, of the 178 students who took the final exam, 98 of them were in good standing. Among those 98, we have the following statistics: The first column is a grade range. The second column is the percentage of students in good standing whose final exam letter grade is in that range. A- or above 24.49% B- or above 54.08% C- or above 84.69% D or above 96.94% For flipping the classroom to be effective, it is paramount that students watch the recorded videos, and attend class. ---------------------------------------------------------------------- Raw data for Lec 030 The first column is a letter grade on the final exam. The last column has the percentage of students with that grade. A or A- 33/178 = 18.54% B+ or B or B- 45/178 = 25.28% C+ or C or C- 57/178 = 32.02% D 30/178 = 16.85% F 13/178 = 7.30% total 99.99% ----------------------------------- Raw data for all lecture sections The first column is a letter grade on the final exam. The last column has the percentage of students with that grade. A or A- 75/504 = 14.88% B+ or B or B- 123/504 = 24.40% C+ or C or C- 176/504 = 34.92% D 92/504 = 18.25% F 38/504 = 7.54% total 99.99% ----------------------------------- Raw data for students in good standing Of the 98 students in good standing (as defined above), we have the following statistics: The first column is a letter grade on the final exam. The last column has the percentage of students in good standing with that grade. A or A- 24/98 = 24.49% B+ or B or B- 29/98 = 29.59% C+ or C or C- 30/98 = 30.61% D 12/98 = 12.24% F 3/98 = 3.06% total 99.99% ----------------------------------------------------------------------
