Subclaims¶

q2 i? Open-ended mobilization was more beneficial for high school students presumed to have lower topic knowledge than for undergraduates presumed to have higher topic knowledge (Wetzels et al., 2011b, as reported by the review). → Courtney Hattan 2023

Courtney Hattan 2023¶

q2 · i? · review · r3

The review reports, citing Wetzels et al. (2011b), a comparison of written open-ended mobilization to perspective taking. The authors explained mobilization lets students freely activate loosely connected concepts, whereas perspective taking requires activating a particular schema.

"They found that open-ended mobilization was more beneficial for high school students presumed to have lower topic knowledge, compared to undergraduate students assumed to have higher topic knowledge."
