Table 3 Local environment analysis (presence, average number of relationships, and average correctness) of context-specific structures that were not provided in instructions (n = 329 models). Relationships are the number of labeled arrows connected to the structure and correctness is the quality of those relationships. Only post-lesson models were analyzed because presence on pre-lesson models was below 10%
