Change in size and quality of student-generated conceptual models from a pre-lesson to post-lesson activity. Size was quantified as number of labeled arrows (relationships) that could be scored for the quality of the description. Quality for each relationship in a student model was assessed on an incorrect (1), vague (2), and technically correct (3) score and the change represented the change in average model score per student from pre to post
