James Kim and Mary Burkhauser explain that, to help students apply what they learn from one reading task to another reading task, educators should consider developing…

Analyses that reveal how treatment effects vary allow researchers, practitioners, and policymakers to better understand the efficacy of educational interventions. In practice, however, standard statistical methods for addressing heterogeneous treatment effects (HTE) fail to address the HTE that may exist "within" outcome measures. In…

We developed a sustained content literacy intervention that emphasized building domain and topic knowledge from Grade 1 to Grade 2 and evaluated transfer effects on students' reading comprehension outcomes. The Model of Reading Engagement (MORE) intervention emphasizes thematic lessons that provide an intellectual framework for helping students…

Correlational evidence suggests that reading skills are strongly related to the amount of reading students do outside of school. Experimental evidence testing whether this relationship is causal is lacking. We report the results from a…

This experimental study aimed to replicate and extend a previous efficacy study of an elementary grade content literacy intervention that demonstrated positive effects on students' vocabulary knowledge depth, argumentative writing, and reading comprehension. Using a cluster (school) randomized trial design, this replication experiment was…
