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? Control-condition students mentioned the evaporation explanation significantly more often than treatment-condition students after seeing the Mpemba problem, confirming the prior-knowledge manipulation succeeded. → Henk G. Schmidt & Jerome I. Rotgans 2021
Evidence¶
Henk G. Schmidt & Jerome I. Rotgans 2021¶
Henk G. Schmidt & Jerome I. Rotgans. (2021). Epistemic Curiosity and Situational Interest: Distant Cousins or Identical Twins?. Educational Psychology Review. https://doi.org/10.1007/s10648-020-09539-9
q3 · i? · causal · r2
Manipulation check counting evaporation-explanation mentions in students' written responses. Control students mentioned it more ("Mcontrol =. 3 4" vs "Mtreatment =. 1 5"), F(1,146) = 5.70, p = .018, confirming differential prior knowledge.
"After being presented with the Mpemba problem, the students in the control condition mentioned the evaporation explanation significantly more often: Mcontrol =. 3 4 (SD =. 5 6 ) v sMtreatment =. 1 5 (SD =. 4 0 ) ,F(1,146) = 5.70, p =. 0 1 8 ."
Discussion¶
Related Claims¶
- In the control condition, no arousal or decrease of either measure occurred because prior knowledge eliminated the knowledge gap — related
- In the treatment condition, both epistemic curiosity and situational interest increased after problem presentation and decreased after the explanatory text — reports the opposite
