Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

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…

Small-group, text-based discussions are a prominent and effective instructional practice, but the literature on the effects of different group composition methods (i.e., homogeneous vs. heterogeneous ability grouping) has been inconclusive with few direct comparisons of the two grouping methods. A yearlong classroom-based intervention was…

This article presents findings from an intervention across sixth and seventh grades to teach academic words to middle school students. The goals included investigating a progression of outcomes from word knowledge to comprehension and investigating the processes students use in establishing word meaning. Participants in Year 1 were two sixth-grade…

The Reading Apprenticeship instructional framework was developed by WestEd's Strategic Literacy Initiative (SLI) two decades ago to help teachers provide the literacy support students need to be successful readers in the content areas. It has since reached over 100,000 teachers in schools across the country, at the middle school, high school, and…

This study evaluated the effectiveness of an intervention for second graders at risk for academic failure, which taught reading comprehension embedded in social studies content. The intervention included instruction about the structure of cause/effect expository text, emphasizing clue words, generic questions, graphic organizers, and close…

This study examined the effectiveness of a yearlong, researcher-provided, Tier 2 (secondary) intervention with a group of sixth-graders. The intervention emphasized word recognition, vocabulary, fluency, and comprehension. Participants scored below a proficiency level on their state accountability test and were compared to a similar group of…
