q2 i? 31 of 38 students in the PS conditions generated only one solution attempt, whereas students in the original study generated about four different solution attempts. → Loibl 2024

q2 · i? · causal · r2

Exploratory analysis of the problem-solving worksheets of the 38 students in the PS-I and PS-Its conditions counted solution attempts as an indicator of an effective problem-solving phase. Most students "generated only one solution attempt"; the authors contrast this with the original study's mean of 4.13 attempts (SD = 1.35).

"Out of the 38 students, 31 students generated only one solution attempt, 6 students generated two solution attempts, and 1 student generated three solution attempts."
