Subclaims¶

q2 i? One set of pedagogical tools was highly effective for learners with a better initial grasp of the object of learning, another set was equally effective for learners with a weaker initial grasp, and both sets were equally ineffective when used for the wrong group of learners. → Ming Fai Pang 2013

Evidence¶

Ming Fai Pang 2013¶

Ming Fai Pang, Ference Marton. (2013). Interaction between the learners’ initial grasp of the object of learning and the learning resource afforded. Instructional Science, 41, 1065–1082. https://doi.org/10.1007/s11251-013-9272-7

q2 · i? · causal · r?

The article's second study, on the same economic principle, compared two sets of pedagogical tools across groups of learners differing in initial grasp; the text reports the interaction pattern and states "The two sets were equally ineffective when used for the ‘wrong’ group of learners." No effect size is printed in the available text.

"One set of the pedagogical tools was found to be highly effective for learners with a better initial grasp of the object of learning, while another set was found to be equally effective for learners with a weaker initial grasp of the object of learning."
