Subclaims¶

q3 i? Community detection on FCI answer distributions detected 13 student groups across 107 students with modularity Q = 0.53; the three largest groups showed accuracy rates of 77%, 73%, and 53%. → Bartley 2019 q3 i? Group A's incorrect answers aligned almost exclusively with the impetus force module, while Group C's incorrect answers spanned five conceptual modules at similar rates. → Bartley 2019 (2)

q3 · i? · associational · r2

Module analysis using nonparametric sparsification and InfoMapR community detection on the Students × Responses matrix from 107 students. After excluding one group for greater head motion, three normative groups (n = 24, 17, 10) were carried into group-level neuroimaging analyses.

"Module analysis detected 13 student groups across 107 students who answered similarly to each other during FCI problem solving with a modularity of Q = 0.53 (Fig. 3a). Four groups had ten or more members (i.e., normative groups)."

q3 · i? · associational · r2

Group-level characterization of response profiles against nine previously measured physics conceptual modules. Group B (n = 17) achieved 73% accuracy mixing impetus force and gravitational-action confusions; Group C (n = 10) achieved 53% accuracy with incorrect answers spread across five modules including impetus force and mass-determines-falling.

"Group A (n = 24) achieved an accuracy rate of 77% across all FCI questions, indicative of being highly Newtonian thinkers."
