Subclaims¶

q3 i3 Proportion of expert symptoms collected during problem representation correlated with overall expert-like evidence collected (r = 0.59). → Lajoie 2001 q3 i3 Library use correlated with ordering expert-like diagnostic tests (r = 0.42). → Lajoie 2001 (2)

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 · i3 · associational · r1

Pearson correlational analysis of computer-trace data from 20 groups, comparing student actions to expert benchmarks. The correlation between "proportion of expert symptoms collected during problem representation" and overall expert-like evidence was r = 0.59, p = 0.002.

"This analysis revealed a significant correlation between proportion of expert symptoms collected during problem representation and overall evidence collected that was expert-like ( r = 0.59, p = 0.002)."

Lajoie 2001 (2)¶

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 · i3 · design · r2

Same correlational analysis of BioWorld trace data: library entries (declarative knowledge) positively correlated with expert-like diagnostic tests ordered, r = 0.42, p = 0.04. The authors also report high evidence collectors scored highly on expert-like tests (r = 49, p = 0.02).

"The declarative knowledge acquired in the library was positively correlated with the proportion of expert-like diagnostic tests ordered (r = 0.42, p = 0.04)."
