Subclaims¶

q3 i? The H-group's essay network overlap with the expert network was much higher than the L-group's (Z = −5.28, p <.001), and their essay network gcent was also more expert-like (Z = −4.25, p <.001). → Chen 2025

q3 · i? · associational · r2

Post-study essay task with 68 Study 2 students (34 high-scoring, 34 low-scoring on the prior final exam); essays were transformed into networks with ALA-Reader and tested nonparametrically because data were not normal. "H-group students' essay network overlap were structured much more like the expert network"; no effect size printed.

"Results show that H-group students' essay network overlap were structured much more like the expert network (M rank = 4.20, [3.08–5.10]) than those in the L-group (M rank = 0, [0–1]), Z = − 5.28, p <.001."

Discussion¶

Learner Variables¶

• Prior Knowledge — predictor: learners who differ on it differ in outcomes
