Testing the effectiveness of two natural selection simulations in the context of a large-enrollment undergraduate laboratory class

Table 1 Four behavioral categories and mutually exclusive and comprehensive behaviors recorded in each category

	Gaze	Verbal	Motor		Affect
	Gaze	Verbal	Physical	Virtual	Affect
Engaged	Activity	Peer	Activity-related	Activity-related	Focus
	Paper	TA	Using lab objects	Mouse	Positive
	Peer		Typing	Typing
	TA		Pointing	Pointing
			Walking
			Writing	Writing
Neutral		No verbal	No motor	No motor
Unengaged	Phone	Peer off-task	Texting	Texting	Negative
Unengaged	Other off-task		Other off-task	Other off-task	Focus off-task

Most behaviors in each category suggest students are engaged or unengaged in the simulation activity, but verbal and motor categories include the possibility of no behavior, which cannot be classified as either engaged or unengaged. Motor categories were differentiated by treatment due to the different nature of the physical and virtual activities
