Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Freeman's graph centrality (gcent) of participant networks was not related to network expert overlap nor to posttest scores in Study 1, and not related to any other measures in Study 2. → Chen 2025

q3 · i? · associational · r1
Study 1 Pearson correlation analysis among network overlap, gcent, Qin and Unit 3 scores; the article reports "Graph centrality (gcent) net- work form showed no relationship to network expert overlap nor to posttest scores." No effect size is printed, so impact is null.
"Graph centrality (gcent) net- work form showed no relationship to network expert overlap nor to posttest scores."
Discussion¶
Related Claims¶
- Under self-directed learning, sorting-task network overlap correlates significantly with immediate and one-month-delayed posttest scores — related
- In classroom-learned history content, sorting-task network overlap with an expert network correlates significantly with both lesson test and unit test scores one month later — related
- High prior knowledge students produced substantially more expert-like essay networks than low prior knowledge peers after self-directed study — related
- Sorting tasks elicited networks with more expert overlap than essay writing, suggesting sorting better captures nascent conceptual structures — related
