This article provides the first causal evidence of a system-wide corequisite reform in Tennessee, which mainstreams underprepared students into college-level courses with concurrent support. Using regression discontinuity and difference-in-regression-discontinuity designs, we find that, for those on the margin of college level, students placed…

Harnessing a cluster randomized controlled trial, we estimated the impact on students' advanced placement (AP) examination performance of a project-based learning (PBL) approach to AP compared with a lecture-based AP approach. Through PBL, teachers primarily play a facilitator role, while students work on complex tasks organized around central…

We present results from the first randomized experiment of a remedial inquiry-based science education program for low-performing elementary students in a developing country. Among third-grade students in 48 low-income public elementary schools in Metropolitan Lima who score in the bottom 50% of their school baseline science distribution, half are…

This is one of the first evaluations of a "growth-mindset" intervention at scale in a developing country. I randomly assigned 202 public secondary schools in Salta, Argentina, to a treatment group in which Grade 12 students were asked to read about the malleability of intelligence, write a letter to a classmate, and post their letters in…

Research has focused predominantly on how teachers affect students' achievement on standardized tests despite evidence that a broad range of attitudes and behaviors are equally important to their long-term success. We find that upper-elementary teachers have large effects on self-reported measures of students' self-efficacy in math, and happiness…

We use data from a randomized controlled trial of a middle school science intervention to explore the causal mechanisms by which the intervention produced previously documented gains in student achievement. Our study finds that implementation fidelity, operationalized as a measure of the frequency of implementation of the cognitive science…

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…

We used population-based, longitudinal data to investigate the relation between mathematics instructional practices used by first-grade teachers in the United States and the mathematics achievement of their students. Factor analysis identified four types of instructional activities (i.e., teacher-directed, student-centered,…

This article presents the findings of an evaluation of the eMINTS (enhancing Missouri's Instructional Networked Teaching Strategies) professional development program. eMINTS is an intensive teacher professional development program designed to promote inquiry-based learning, support high-quality lesson design, build community among students and…

This study examines how high-quality professional development can promote the diffusion of effective teaching strategies among teachers through collaboration. Drawing on longitudinal and sociometric data from a study of writing professional development in 39 schools, this study shows that teachers' participation in professional development is…

Student engagement is a critical aspect of the learning process and a known predictor of school success. We report on an evaluation of a classroom intervention, CareerStart, designed to promote engagement through the use of career-relevant instruction whereby teachers use examples to tie the lesson material to knowledge and skills students can see…

This study investigates the influence of a school's pre-existing social resources on the implementation of a comprehensive literacy-coaching program (Content-Focused Coaching [CFC]). Elementary schools were randomly assigned to receive a CFC-trained coach (n = 15 schools) or to continue with the literacy coaching resources that are standard for…

This study consists of two parts: (1) a discussion of legal education, which uses the Socratic method of pedagogy and the study of case histories, and (2) an examination of aspects of legal education that might be used as a model for educating evaluators. (Author/JAZ)

The use of structural equation modelling in curriculum evaluation is discussed in two stages: first, a process model for curriculum evaluation from instructional theory is derived; second, the structural equation model derived from the process analysis and its applications to curriculum evaluation are described.

In the past two decades, several major initiatives were launched to improve mathematics and science education. One prominent feature in these efforts was a new approach to teaching mathematics and science, referred to as "reform-oriented" teaching. Although past studies suggest this approach may improve student achievement, the relationships…
