This study examined the initial efficacy of World Generation (WorldGen), a Tier I social studies instructional approach for emergent bilingual (EB) students and their native English-speaking (non-EB) peers in Grades 6 and 7. WorldGen builds on prior research on instructional practices that have been associated with improved content knowledge and…

Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math.…

We present findings from a randomized controlled trial of "Descubriendo la Lectura" (DLL), an intervention designed to improve the literacy skills of Spanish-speaking first graders, who are struggling with reading. DLL offers one-on-one native language literacy instruction for 12 to 20 weeks to each school's lowest performing…

The acquisition of early mathematical knowledge is critical for successful long-term academic development. Mathematical language is one of the strongest predictors of children's early mathematical success. Findings from previous studies have provided correlational evidence supporting the importance of mathematical language to the development of…

The achievement gaps between poor and more affluent students are persistent and chronic, as many students living in poverty are also members of more isolated communities where dialects such as African American English and Southern Vernacular English are often spoken. Non-mainstream dialect use is associated with weaker literacy achievement. The…

Intelligent Tutoring Systems (ITSs) are beneficial for individual students learning in several domains, including mathematics where they have been used to support both secondary and elementary students. Collaborative learning may be beneficial to include in ITSs, particularly for conceptual knowledge. There is little work on collaborative ITSs,…

Developed in response to concerns that too few students were enrolling and succeeding in postsecondary education, early college high schools are small schools that blur the line between high school and college. This article presents results from a longitudinal experimental study comparing outcomes for students accepted to an early college through…

Despite the growing popularity of dual-credit courses as a college readiness strategy, numerous reviews of the literature have noted a number of important limitations of the research on the effects of dual-credit on student postsecondary outcomes. This study addressed these gaps in the literature by estimating the impact of dual-credit courses on…

Across the country, a growing number of recent high school graduates are participating in summer bridge programs. These programs provide accelerated and focused learning opportunities in order to help students acquire the knowledge and skills needed for college success. The state of Texas has given particular attention to summer programs as a way…

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…

In this article, we present the results from a longitudinal examination of the impact of a "Standards"-based or reform mathematics curriculum (called CMP) and traditional mathematics curricula (called non-CMP) on students' learning of algebra using various outcome measures. Findings include the following: (1) students did not sacrifice…

This study aimed to determine the efficacy of a content acquisition and reading comprehension treatment implemented by eighth-grade social studies teachers. Using a within-teacher design, the eighth-grade teachers' social studies classes were randomly assigned to treatment or comparison conditions. Teachers (n = 5) taught the same instructional…

This study investigated the relative effects of three treatments with varying instructional emphases in reading with a comparison condition. Eighty-seven students in fourth grade with reading impairments were assigned through stratified random assignment to one of four conditions: (a) comprehension emphasis, (b) word study emphasis, (c) emphasis…

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were…
