Subclaims¶

q3 i? Time on task did not differ across the three task conditions (p = .16). → Ard W. Lazonder 2009 q3 i? The number of unique and duplicated experiments did not differ across conditions (p = .29), nor did the percentage of unspecified hypotheses (p = .24). → Ard W. Lazonder 2009 (2)

Evidence¶

Ard W. Lazonder, Pascal Wilhelm, Emiel van Lieburg. (2009). Unraveling the influence of domain knowledge during simulation-based inquiry learning. Instr Sci, 37, 437-451. https://doi.org/10.1007/s11251-008-9055-8

q3 · i? · causal · r2

In the randomized experiment, time on task (means 28.76, 25.50, and 32.56 minutes across concrete, intermediate, and abstract conditions) showed no effect of task type; equivalence was not tested.

"Univariate analysis of variance (ANOVA) showed that task type had no effect on this measure ( F(2,53) = 1.93, MSE = 123.19, p = .16), indicating that participants in the three conditions needed as much time to complete their version of the task."

q3 · i? · causal · r2

Same experiment: a MANOVA on unique and duplicated experiment counts showed no significant task-type effect. A separate univariate ANOVA on unspecified hypotheses was also non-significant (F(2,52) = 1.49, p = .24).

"Multivariate analysis of variance (MANOVA) yielded no significant effect of task type on the number of unique and duplicated experiments ( F(4,106) = 1.25, p = .29)."

Discussion¶

Related Claims¶

• Hypothesis specificity differed by task type: intermediate participants stated fewer partially-specified hypotheses than abstract participants, but more fully-specified hypotheses than concrete participants — reports the opposite
• Concrete-task participants conducted a significantly lower percentage of exploratory experiments than intermediate-task participants, whose exploratory percentage matched the abstract condition — related
