q3 i? The experimental group improved significantly from pre-test (M = 12.37) to post-test (M = 21.74). → Davor I 2026

Evidence¶

Davor I 2026¶

Davor I (2026) Generative AI-supported instruction as a cognitive scaffold: effects on senior high school students' geometric reasoning and proof construction. Front. Educ. 11:1869961. https://doi.org/10.3389/feduc.2026.1869961

q3 · i? · causal · r2

Paired-samples t-test within the experimental group in the quasi-experimental study. Scores rose from "12.37 (SD = 3.04)" to 21.74 (SD = 4.42), t(42) = −18.410, p < .001; no effect size is printed for this within-group change.

"Similarly, the experimental group showed a significant improvement from 12.37 (SD = 3.04) to 21.74 (SD = 4.42), t(42) = −18.410, p < .001."

Discussion¶

Learner Variables¶

• Geometric Reasoning — outcome: instruction changes it
