q3 i? Differences in total and unique counts of initiating annotations and re-annotations between high- and low-learning groups were not statistically significant. → Yiqiu Zhou and Jina Kang 2026

Evidence¶

Yiqiu Zhou and Jina Kang 2026¶

Yiqiu Zhou and Jina Kang. (2026). From individual annotations to shared attention: How re-annotation supports collaborative knowledge building in CSCL. Intern. J. Comput.-Support. Collab. Learn. https://doi.org/10.1007/s11412-026-09486-7

q3 · i? · associational · r1

Mann-Whitney U tests on four quantity/breadth metrics across the same 16 groups found no significant differences (e.g., unique initiating annotations U = 22.5, p = 0.366; unique re-annotations U = 20.0, p = 0.234). Equivalence was not tested. The paper notes "limited sample size" as a possible reason.

"While high-learning groups generated a greater number of initiating annotations, low-learning groups exhibited a higher total number of re-annotations. However, these differences were not statistically significant."

Discussion¶

Related Claims¶

• High-learning groups show a significantly shorter time gap between initiating annotations and re-annotations than low-learning groups, indicating reduced attention distance — related
• Epistemic network analysis shows high-learning groups integrate re-annotations with knowledge-confirming discourse more densely than low-learning groups — related
• Initiating annotation frequency strongly correlates with re-annotation frequency across groups (Kendall's tau = 0.95) — related
• Group-level annotation activity shows no significant association with verbal knowledge-construction frequency — related
