Data in the graph represent the change in performance on test questions regarding the structure and function of various bacterial cell components. Questions were identical on the tests given prior to and after the activity. Data for prior to activity are for two semesters (n=31). Data for the after activity are for one semester (n = 17). Results show that the implementation of a new learning activity and a formative assessment did in general improve student performance in this area. Additional data is needed to confirm these findings.
