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? Students' belief-meter confidence rose significantly between first and last diagnosis during BioWorld problem solving. → 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
q3 · i? · design · r2
Computer-trace data from 20 grade-9 groups solving digestion cases in BioWorld; a one-way RM ANOVA on belief-meter entries found students significantly increased their confidence about their diagnosis at the time of their final argument (F(1,19) = 51.042, p = 0.00). Means are descriptive; no effect size is printed.
"Belief meter entries indicated how confident students were at the time of their first diagnosis (belief M = -1.01, SD = 1.94) and last diagnosis (belief M = 14.08, SD = 6.36)."
Discussion¶
Related Claims¶
- In BioWorld, confidence was tied to final diagnostic accuracy but not to the first hypothesis — related
- In BioWorld, expert-like initial problem representation and library use correlate with expert-like evidence collection and diagnostic-test ordering — related
- Most students solved BioWorld cases, and successful solvers took less time and fewer actions than unsuccessful solvers — related
