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 total number of concepts in case explanations first increases and then decreases across expertise levels, replicating the encapsulation hypothesis. → 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
A 4-level (second-, fourth-, sixth-year students, internists) experiment with two internal-medicine cases and three reading-time conditions; explanations schematised as semantic networks. The article reports the inverted U-shaped relationship as "(F(3. 84)=8.61. p=O.OOOl)".
"Like in the original study, the total number of concepts had an inverted U-shaped relationship with level of expertise (F(3. 84)=8.61. p=O.OOOl)."
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, model concepts increase monotonically with expertise while detailed biomedical concepts show an inverted U, confirming knowledge encapsulation — related
