Fig.Ā 3From: Comparing learning outcomes of two collaborative activities on random genetic drift in an upper-division genetics courseRasch measures in the two activities for both pre-(red) and post-tests (blue). Rasch measures in logits are plotted for HLM model with all background variables modeled as random effects. The interaction between learning gains and the activity type is statistically significant (pā<ā0.001). Vertical lines indicate 95% confidence intervalsBack to article page
