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 i1 While controlling for condition, participants with low prior knowledge gained significantly more (29%) from pre-test to post-test than high prior knowledge participants (16%). → Taub 2019
Evidence¶
Taub 2019¶
Taub, M., & Azevedo, R. (2019). How Does Prior Knowledge Influence Eye Fixations and Sequences of Cognitive and Metacognitive SRL Processes during Learning with an Intelligent Tutoring System? Int J Artif Intell Educ (2019) 29:1-28. https://doi.org/10.1007/s40593-018-0165-4
q3 · i1 · associational · r2
ANCOVA with prior knowledge group (2 levels) as independent variable, proportional learning gain as dependent variable, and condition as covariate in the full sample (N = 194). The article reports F(1,191) = 7.22, p <. 01, ηp2 = .036, "significantly lower proportional learning gains" for HPK.
"participants with high prior knowledge had significantly lower proportional learning gains ( M =. 1 6 , SD = .42) than participants with low prior knowledge ( M = .29, SD = .22)."
Discussion¶
Learner Variables¶
- Prior Knowledge — predictor: learners who differ on it differ in outcomes
Related Claims¶
- No significant differences in proportions of fixations on single areas of interest by prior knowledge group during learning with MetaTutor — related
- Low Prior Knowledge students achieved significantly higher normalized learning gains than High Prior Knowledge students — related
- HPK students improved significantly only in the Low-Agency condition, with a large post-test advantage over HPK peers in High-Agency (d = .95) — related
- Metacognition and critical-thinking tutors show mixed results: Operation ARA gained 1.4 σ, SEEK showed no significant improvement, and MetaTutor's learning-efficiency advantage disappeared when agent time was counted — related
