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.
q2 i? Higher and lower skill subjects were equally planful in a verbal troubleshooting task; differences emerged only in the utility of plans, with less skilled subjects lacking domain-particularized strong methods. → Ellen P. Hall 1995

The report attributes this to Glaser et al. (1985), who examined plan generation by skilled and less skilled avionics technicians in a verbal troubleshooting task and found the two groups "did not differ with respect to the frequency of plan generation." The report quotes that less skilled subjects "are way behind on stronger problem-solving methods, methods particularized to the specific technical domain." No effect sizes are printed.
"Both higher and lower skill subjects were planful. The differences arise only when the utility of the plan for solving the problem is considered."
Discussion¶
Related Claims¶
- Successful discoverers regulate learning more systematically, planning experiments and monitoring progress, while unsuccessful learners work unsystematically
- The report attributes to expert-novice comparisons that experts relate symptoms to inoperative system functions while novices focus on physically proximal components — related
- Evidence that domain-general perceptual-cognitive skills distinguish athletes is mixed; expertise appears domain-specific — a broader claim this one bears on
- Low-prior-knowledge students struggle to deploy key self-regulatory processes during learning — reports the opposite
