Subclaims¶

q2 i? A meta-analysis found exploration followed by direct explicit instruction works only if the subsequent instruction directly explains the solutions; other studies support instruction-first, arguing exploration first overloads working memory. → Lin Zhang 2022 q1 i? Ashman et al. (2020) proposed that exploration-first results occur with low complexity tasks while instruction-first is relatively effective for high complexity tasks. → Lin Zhang 2022 (2)

Evidence¶

Lin Zhang 2022¶

Lin Zhang, Paul A. Kirschner, William W. Cobern, John Sweller. (2022). There is an Evidence Crisis in Science Educational Policy. Educational Psychology Review. https://doi.org/10.1007/s10648-021-09646-1

q2 · i? · theoretical · r3

The commentary reports, citing Loibl et al. (2017), a meta-analysis of exploration-then-instruction studies. The commentary attributes the finding to that meta-analysis; no effect size is printed.

"a recent meta-analysis by Loibl et al. (2017) reviewed various studies examining the approach of exploration followed by direct explicit instruction and found that this combination only works if the subsequent instruction specifically and directly explains the solutions to learners"

Lin Zhang 2022 (2)¶

Lin Zhang, Paul A. Kirschner, William W. Cobern, John Sweller. (2022). There is an Evidence Crisis in Science Educational Policy. Educational Psychology Review. https://doi.org/10.1007/s10648-021-09646-1

q1 · i? · theoretical · r2

The commentary reports Ashman et al.'s (2020) theoretical proposal using task complexity to explain the inconsistency between sequencing findings. This is an interpretive argument, not a new empirical test.

"They argued that results favoring the exploration-first approach occur if learners are engaged in low complexity tasks. In contrast, when learners are involved in high complexity tasks, a direct explicit instruction first approach should be relatively effective"
