Table 2 Local environment analysis (presence, average number of relationships, and average correctness) of provided structures in students’ conceptual models (n = 289 students). Relationships are number of labeled arrows connected to the structure and correctness is the quality of those relationships. Models were only included in the analysis if the student created a conceptual model that contained at least 1 labeled relationship on the pre- and post-lesson activity
