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? The number of model concepts rises monotonically with expertise level and detailed biomedical concepts peak at intermediate expertise. → Boshuizen 1995
Evidence¶
Boshuizen 1995¶
Boshuizen, H. P. A., Schmidt, H. G., Custers, E. J. F. M., & van de Wiel, M. W. (1995). Knowledge Development and Restructuring in the Domain of Medicine: The Role of Theory and Practice. Learning and Instruction. https://www.sciencedirect.com/journal/learning-and-instruction
q3 · i? · causal · r2
Same Experiment 1 design; explanations matched against an ideal explanation to count model concepts and detailed concepts. The article states advanced students "used more detailed concepts than experts and junior students".
"the number of model concepts applied in the case explanations increased monotonically with expertise level (F(3, 84)=19.37, p=O.OOOl), while the number of more detailed biomedical concepts applied had an inverted U-shaped relation with expertise level"
Discussion¶
Learner Variables¶
- Prior Knowledge — predictor: learners who differ on it differ in outcomes
Related Claims¶
- In Experiment 2, the proportion of fault (pathophysiological) statements decreased monotonically with expertise regardless of probe — related
- In Experiment 1, the total number of concepts used in pathophysiological case explanations shows an inverted U-shaped relation with level of medical expertise — related
