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? Lesson-level regressions showed significant impact of prior biology knowledge on new AI knowledge in Lessons 1 and 2, but no significant impact in Lessons 3 or 4. → Shenghua Zha 2025

q3 · i? · design · r2

Per-lesson multiple regressions on worksheet fill-in-blank scores. Lesson 1: F(1, 21) = 6.49, p < .05, R2 = 0.24; Lesson 2: F(1, 30) = 33.08, p < .01, R2 = 0.52, both significant. Lesson 3: F(1, 25) = 0.01, p = .94; Lesson 4: F(2, 25) = 1.28, p = .30, both non-significant.

"Results of regression analyses for Lesson 1 ( F(1, 21) = 6.49, p <.05, R2 = 0.24) and Lesson 2 ( F(1, 30) = 33.08, p <.01, R2 = 0.52) showed the significant impact of students' prior biology on their AI knowledge (Table 4)."

Discussion¶

Learner Variables¶

Prior Knowledge — predictor: learners who differ on it differ in outcomes

Prior Knowledge Determines New Learning — the general claim this finding bears on, with the studies behind it
Post-test biology knowledge and pre-test AI knowledge significantly predicted post-test AI knowledge — related
Students who transferred prior-domain knowledge tended to offer correct explanations in the other domain — related
Prior attainment predicted several dialogue variables in preliminary regression analyses
Students' overall AI knowledge improved significantly after four integrated AI-biology lessons — related
Prior knowledge directly predicted all three formative assessments (β=.11, β=.24, β=.11) but no future interest outcomes. — related
