Subclaims¶

q3 i? Accuracy on Question #4, which required coordination of two or more representations, was lowest among the three scored question types. → Mike Stieff 2011 q3 i? Accuracy differed between question types, and Question #4 was significantly lower than Questions #2 and #3 collapsed, per Scheffé post-hoc test. → Mike Stieff 2011 (2)

q3 · i? · associational · r1

Descriptive accuracy data from the problem-solving interview of ten organic chemistry undergraduates across three animations. Question #4 accuracy was lowest: "student accuracy was the lowest (M = 1.2, SD = .97)".

"For Question #4, which required the coordination of two or more representations, student accuracy was the lowest (M = 1.2, SD = .97)."

q3 · i? · associational · r1

ANOVA over the nine scored interview questions of the ten-participant interview study. "A one-way analysis of variance showed that the accuracy rate differed between the questions, F(2,26) = 7.04, p < .05."

"A one-way analysis of variance showed that the accuracy rate differed between the questions, F(2,26) = 7.04, p < .05, and a post-hoc analysis using the Scheffé test indicated that the average number of correct responses to Question #4 was significantly lower"
