*If multiple sections of a course are taught by different instructors in a particular semester, please separate assessment data from sections taught by instructors who employ reformed or interactive curriculum and teaching methods and data from sections taught by instructors who employ traditional curriculum and teaching methods.
**If possible, calculate average scores only from students whose pretests and posttests can be matched.
***Use the following formula to calculate the average normalize gain for matched pre and posttest pairs:
Average normalized gain g =
****Standard error =
*****Dropped 5 students whose pretest scores were a perfect 100% (causing a divide by zero in calculating their normalized gain). Dropped 1 student whose normalized gain was 600% (about 19 sigma from the mean). Dropped 1 student whose normalized gain was 900% (about 27 sigma from the mean).
The Large Lecture Sections also utilize some modern teaching methods (e.g., Peer Instruction).
