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 i3 The concrete condition had a significantly lower percentage of exploratory experiments than the intermediate condition (r = .52). → Ard W. Lazonder 2009

q3 · i3 · causal · r2
In the randomized three-task experiment, ANOVA showed a significant difference in exploratory experiments (F(2,53) = 11.28, p < .01); the concrete condition (M = 12.27%) was lower than the intermediate condition (M = 46.58%), "t(53) = 4.45, p\ .01, r = .52".
"Planned contrasts revealed that participants in the concrete condition had a significantly lower percentage of exploratory experiments than participants from the intermediate condition ( t(53) = 4.45, p\ .01, r = .52)."
Discussion¶
Related Claims¶
- In multiple regression, the percentage of exploratory experiments was the strongest predictor of performance success, negatively related to it
- Hypothesis specificity differed by task type: intermediate participants stated fewer partially-specified hypotheses than abstract participants, but more fully-specified hypotheses than concrete participants — related
- Concrete-task participants achieved higher performance success than intermediate-task participants in simulation-based inquiry, while intermediate and abstract conditions did not differ significantly — related
- Task type did not affect time on task, number of unique experiments, duplicated experiments, or percentage of unspecified hypotheses — related
