Fig. 3From: Testing the effectiveness of two natural selection simulations in the context of a large-enrollment undergraduate laboratory classObservations of student behavior while doing the physical simulation and virtual simulation lab activities. We conducted observations of student behavior in five lab sections for each treatment, over the course of 4 days (for details see “Methods”). Student gaze (a), verbal behavior (b), motor behavior (c), and affect (d) were recorded in mutually exclusive categories. There are significant differences between treatments in the distributions among behaviors in each categoryBack to article page
