In F12 and F13 we also calculate gains on unmatched data. The unmatched gain for F12 was 0.11 and the unmatched gain for S13 was 0.21.

*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 pre-tests and post-tests can be matched.

Unfortunately, between F07 and S12, we are unable to match data at CSU due to difficulties with student ID's. In F12 we implemented a new ID system for data collection. This has enabled us to include matched data for the last year. In cases where the pretest N and posttest N are the same or nearly the same the calculated gains will be similar to the matched gains.

***Use the following formula to calculate the average normalize gain for matched pre- and post-test pairs:

Average normalized gain g =

****Standard error =

 

For data between F07 and S12, since data is not matched the gain was calculated using the entire class(%post-%pre)/(100%-pre).

Last year's gain and standard error are calculated using the above equations.
