Subclaims¶

q2 i? A large majority of participants reported B equations as more difficult than A equations, although inverse efficiency showed no significant difference between A and B. → Susac A 2014 q2 i? Older students ranked equation difficulty more accurately, suggesting improving metacognitive skills. → Susac A 2014 (2)

Evidence¶

Susac A 2014¶

q2 · i? · associational · r2

Questionnaire difficulty rankings compared with inverse-efficiency results: "a large majority of participants reported that the B equations are more difficult than the A equa­tions although this is not supported by the obtained results," likely because division is perceived as harder than multiplication.

Post-hoc questionnaire data across grades: "the incr eased number of participants who ranked B equations as easiest among older students suggests that some older participants (from secondary school) became aware of the patterns in the task." The authors link this to improving metacognitive skills.
