This study assesses the implementation and impacts of the Teacher Potential Project (TPP), a program designed by EL Education and which includes an English language arts (ELA) standards-aligned curriculum and embedded professional development for teachers. The study uses a randomized controlled trial (RCT) design to assess the impacts of TPP on…

Middle school algebra students (N = 125) randomly assigned within classroom to a Problem-solving control group, a Correct worked examples control group, or an Incorrect worked examples group, completed an experimental classroom study to assess the differential effects of incorrect examples versus the two control groups on students' algebra…

This article examines the effectiveness of a technology-based algebra curriculum in a wide variety of middle schools and high schools in seven states. Participating schools were matched into similar pairs and randomly assigned to either continue with the current algebra curriculum for 2 years or to adopt Cognitive Tutor Algebra I (CTAI), which…

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…

Student achievement in mathematics has been a focal concern in the United States for many years. The National Research Council's 2001 report and the recent report of the National Mathematics Advisory Panel (2008) both called attention to student achievement in mathematics, and both called for all students to learn algebra by the end of eighth…

This study estimates the effect of one year of Fusion Reading implementation, a multistrategy intervention, builds on the work of the Strategic Instruction Model's Learning Strategies Curriculum and Xtreme Reading by integrating some of the same strategies (e.g., paraphrasing, visual imagery, and self-questioning for information acquisition;…

Teach For America (TFA) and the Teaching Fellows programs are an important and growing source of teachers of hard-to-staff subjects in high-poverty schools, but comprehensive evidence of their effectiveness has been limited. This report presents findings from the first large-scale random assignment study of secondary math teachers from these…

This study reports Year 1 findings from a multisite cluster randomized controlled trial of a cognitive strategies approach to teaching text-based analytical writing for mainstreamed Latino English language learners (ELLs) in 9 middle schools and 6 high schools. There were 103 English teachers stratified by school and grade and then randomly…

This report presents the results of an experiment conducted in Alabama beginning in the 2006/07 school year, to determine the effectiveness of the Alabama Math, Science, and Technology Initiative (AMSTI), which aims to improve mathematics and science achievement in the state's K-12 schools. This study is the first randomized controlled trial…

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of…

The Louisiana Striving Readers evaluation assessed the implementation and effectiveness of the Voyager "Passport Reading Journeys" (PRJ), a widely used supplemental literacy intervention for struggling adolescent readers that reflects the research-based practices recommended by the National Reading Panel (2000) and other more recent…

This project entailed a three-year efficacy evaluation of the Computer and Team Assisted Mathematical Acceleration (CATAMA) Lab developed by the Center for Social Organization of Schools at Johns Hopkins University. The CATAMA Lab was proposed as an immediate and practical approach to addressing the different types of math deficits held by…

This study investigated the differential effects of two problem-solving instructional approaches--schema-based instruction (SBI) and general strategy instruction (GSI)--on the mathematical word problem-solving performance of 22 middle school students who had learning disabilities or were at risk for mathematics failure. Results indicated that the…

Sixth- and seventh-grade students (n=68) with learning disabilities in mathematics received either concrete-to-representational-to-abstract (CRA) or traditional instruction in algebraic transformation equations. Students receiving the CRA instruction outperformed peers receiving traditional instruction on both post-instruction and follow-up tests…

This study examined effects of contextualized math instruction on problem-solving performance of 17 middle school remedial students and 49 average-achieving prealgebra students. Results showed that both remedial and average students receiving contextualized-problem instruction outperformed comparison groups receiving word-problem instruction.…
