· ORS = Oral Rehydration Solutions topic; FWS = Fever Without Source topic.
· N = number of participants; M = mean z-score; SD = Standard Deviation.
· For the ORS and FWS Post-test scores, the F-tests are for the interaction of Case with Tutorial for the partial ANCOVA model for the respective topic while the Overall F-test is from Table 1.
· All analyses adjusted for pre-test score.
· ORS cells are yoked to FWS cells (and vice-versa) per the study design (see Figure 2); for example, all students who were Tutorial +, Patient + for the FWS .Post-test were Tutorial – and Patient – for the ORS Post-test.
