Learning transfer happens across subjects in school, too. A 2022 working paper , as summarized by my colleague Dr. Amber Northern, examined the Model of Reading Engagement (MORE), a multi-year literacy intervention that integrates reading instruction with science and social studies content. The study found both near transfer effects on reading and far transfer effects on math. Now, a follow-up study from two Harvard researchers builds on these findings by investigating the mechanisms by which MORE leads to improved performance in a distant academic domain like math. Specifically, it tests the extent to which third grade reading skills explain the observed effects on fourth grade math achievement.
