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.
q2 i? Role characterizations derived from clustering students on diffusion centralities were validated using qualitative methods and were found to meaningfully relate to academic performance. → Saqr 2021
Evidence¶
Saqr 2021¶
Saqr, M., & López-Pernas, S. (2021). Modelling diffusion in computer-supported collaborative learning: a large scale learning analytics study. Intern. J. Comput.-Support. Collab. Learn. https://doi.org/10.1007/s11412-021-09356-4
q2 · i? · associational · r2
Cluster analysis (k-means after standardization and winsorization; NbClust 12/30 indices supported three clusters) whose discovered roles were checked against manually coded interaction data. The article reports the role characterizations were "validated using qualitative methods" and meaningfully related to academic performance.
"Characterizations of student roles based on diffusion centralities were validated using qualitative methods and were found to meaningfully relate to academic performance"
Discussion¶
Related Claims¶
- Diffusion-based centralities show moderate-to-strong statistically significant positive correlations with the frequency of information sharing and argumentation utterances in CSCL
- Diffusion-based centralities elucidate information exchange and uptake in large-scale collaboration, validated against achievement and qualitative analysis, according to the editors' account of Saqr and López-Pernas's study — possibly the same claim (merge candidate)
- In a correlation meta-analysis across 69 course offerings, diffusion-based centralities correlated with academic achievement with high combined coefficients and predictive intervals — related
