In Fall 2012 MATH 1271 Lec 020 and Lec 070 (my lecture sections), 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, 314 of my (Lec 020 and Lec 070) students took the final exam. Including all the lecture sections, 1197 students took the final exam. ---------------------------------------------------------------------- Summary The first column is a grade range. The second column is the percentage of students in Lec 020/070 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 020/070 All ----------- ------ A- or above 23.25% 15.87% B- or above 50.00% 46.62% C- or above 78.66% 79.45% D or above 89.81% 91.40% There seems to be significant improvement in the "A- or above" range, 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 greatly, but that the effect was not as strong for the rest. ---------------------------------------------------------------------- Students in good standing In 26 lectures and 10 recitations, a 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 35 of those 26 + 10 + 2 = 38 quizzes. In Lec 020 and Lec 070, of the 314 students who took the final exam, 227 of them were in good standing. Among those 227, 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 29.07% B- or above 58.15% C- or above 83.70% D or above 92.95% For flipping the classroom to be effective, it is paramount that students watch the recorded videos, and attend class. ---------------------------------------------------------------------- Raw data for Lec 020 and Lec 070 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- 73/ 314 = 23.25% B+ or B or B- 84/ 314 = 26.75% C+ or C or C- 90/ 314 = 28.66% D 35/ 314 = 11.15% F 32/ 314 = 10.19% total 100.00% ----------------------------------- 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- 190/1197 = 15.87% B+ or B or B- 368/1197 = 30.74% C+ or C or C- 393/1197 = 32.83% D 143/1197 = 11.95% F 103/1197 = 8.60% total 99.99% ----------------------------------- Raw data for students in good standing Of the 227 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- 66/ 227 = 29.07% B+ or B or B- 66/ 227 = 29.07% C+ or C or C- 58/ 227 = 25.55% D 21/ 227 = 9.25% F 16/ 227 = 7.05% total 99.99% ----------------------------------------------------------------------
