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.
q2 i? A MANOVA comparing three coaching conditions on all dependent measures found no significant differences. → Lajoie 2001
Evidence¶
Lajoie 2001¶
Lajoie, S. P., Lavigne, N. C., Guerrera, C., & Munsie, S. D. (2001). Constructing knowledge in the context of BioWorld. Instructional Science, 29(2), 155-186. http://www.jstor.org/stable/41953546
q2 · i? · causal · r1
Exploratory pilot comparing 6 groups (2 teacher-guided, 2 graduate-student-guided, 2 BioWorld-only) selected as equivalent by the teacher; a MANOVA with condition (3) as between-subjects factor found no significant differences at alpha 0.10. Only a test outcome is printed, no effect size.
"A MANOVA was conducted to investigate the condition (3) effects of instruction on all dependent measures of interest. Again, an alpha level of 0.10 was adopted to compensate for the small sample size. No significant differences were found."
Discussion¶
Related Claims¶
- Teacher and researcher coaches both used a cognitive apprenticeship approach but differed in scaffolding style — related
- No supplemental intervention was significantly better than another, and gains were not tied to program type — related
- Teacher-guided classroom discussion before reflection prompts yields higher learning gains than all other support conditions, especially on application-level items — related
- Domain-specific knowledge gains from the learning session were large but comparable across the three experimental conditions — related
