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? Fault statements declined monotonically across expertise levels, further confirming knowledge encapsulation. → 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
Experiment 2 narrative descriptions coded for fault idea units; the article notes the steady decrease, unaffected by probe, "is a further confirmation of the hypothesis of knowlcdgc encapsulation", with experts using shorthand concepts like "virus".
"Figure 6 shows the proportion of fault statements that decreased monotonically (F(3, 81)=16.137; ~~0.001) with increasing expertise levels. No effects (neither main nor interaction) of the kind of probe applied could be found."
Discussion¶
Learner Variables¶
- Prior Knowledge — predictor: learners who differ on it differ in outcomes
Related Claims¶
- In Experiment 1, model concepts increase monotonically with expertise while detailed biomedical concepts show an inverted U, confirming knowledge encapsulation — 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
- Encapsulation and tuning are the cognitive mechanisms responsible for the transition from elaborated knowledge to simplified causal models — a broader claim this one bears on
