Fig. 4

Individual Wright maps of results of A Faculty developed activity group pre-test, B SimBio activity group pre-test, C Faculty-developed activity group post-test, D SimBio activity group post-test. See Fig. 2 legend for Wright map details. Each “#” represents 2 persons. Each “.” represents 1 person. While some of the logit scales are unaligned this is inconsequential as measures from separate Rasch Analysis cannot be directly compared. Instead interpretation must be restricted to the relative positioning of items compared to each other on different Wright maps
