q2 i? Lag sequential analysis showed experimental group students who answered incorrectly engaged with supplementary materials before re-attempting and then answered correctly, whereas control students tended to immediately retry without consulting materials. → Kuan‑Fu Chen 2025

Kuan‑Fu Chen, Gwo‑Jen Hwang, Mei‑Rong Alice Chen. (2025). Precision diagnosis in virtual learning contexts: a predict‑observe‑explain‑diagnose‑based approach to scientific inquiry. Education Tech Research Dev. https://doi.org/10.1007/s11423-025-10527-5

q2 · i? · causal · r2

Lag sequence analysis with GSEQ software of VR learning behavior logs from both groups; significant transitions had Z-scores above 1.96. The article reports students "consistently engaged with the supplementary learning materials before re-attempting the questions" and then improved.

"When experimental group students answered incorrectly (both first- and second-tier questions), they consistently engaged with the supplementary learning materials before re-attempting the questions (e.g., SI → EF; FI → OF). After reviewing the materials, students significantly improved their ability to correctly answer both factual and conceptual questions (EF → SC; OF → FC)."
