This paper contributes empirically to the literature on peer effects in first-grade classrooms. The paper examines peer effects on academic achievement among first graders randomly assigned to their classrooms and to their teachers as part of Tennessee's Project STAR, America's largest ever education experiment. The analysis draws on previously…

The purpose of this professional development study was to examine the impact of Teacher Study Groups on the teacher practice, teacher knowledge, and student outcomes, specifically in the areas of reading comprehension and vocabulary. The multi-site study was conducted in three large urban school districts from three states: California (CA),…

In this paper, the authors estimate the effect of a high school exit exam requirement (relative to no requirement) on students' academic achievement, persistence in high school, and graduation rates. They are particularly interested in the effects of the policy on the students who have low initial skill levels in high school. The study is based on…

This paper will address several gaps in the literature. First, those studies that have attempted to hone in on the relationship between student attendance and achievement in K-12 education have been conducted only at the aggregate level of analysis. Although these papers have provided insight into how attendance may be related to achievement,…

The Scale-Up Pre-K Mathematics project, was conducted at a customary program-wide level of scale in Head Start and state-funded preschool programs in California and Kentucky/Indiana. The objectives of this randomized field trial were twofold: (1) to determine whether the intervention, the Pre-K Mathematics curriculum, continues to be effective…

This study assesses the effects of state exit exams on the student utilization of and performance on Advanced Placement (AP) exams. AP programs have become an increasingly popular way of providing fairly standardized and academically rigorous academic experiences that can prepare high school students for the transition to post-secondary schooling.…

This paper presents new evidence on the effects of exit exam performance on high school persistence and completion as well as on college attendance using data on students from Florida. Specifically, they examine whether initial exit exam performance causes students to drop out of school, changes the likelihood of graduating from high school, and…

This paper presents new evidence on the effect of remediation using a large longitudinal dataset of Texas students. The authors study the effect of being in any remediation, regardless of subject, and also investigate the effect of remediation in different subjects. In particular, they examine whether remediation in math improves student outcomes.…

The present study focused on two main goals. One was to test the "representational mapping hypothesis": The greater the transparency of the mapping between physical materials and desired internal representations, the greater the learning of the desired internal representation. The implication of the representational mapping hypothesis in the…

This study was designed to establish the efficacy of Teaching SMART (Teaching Science, Mathematics and Relevant Technologies); a science professional development program for teachers with students in grades 3 through 5. Teaching SMART promotes scientific inquiry and emphasizes the importance of equity, empowerment, exploration, and fun in the…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

The primary research question for this project was whether a streamlined, relatively inexpensive, counseling-based program that assists low-income high school students with the college and financial application processes can significantly increase college enrollment rates. The intervention was designed to test the hypothesis that lack of…

The research reported in this paper is focused directly on assessing the validity of the "Teaching Knowledge about Reading and Reading Practices" (TKRRP) assessment. Following the recommendations of the Standards for Educational and Psychological Testing (APA/AERA, 1999), the authors see validation as a process of constructing an argument that…

The "Building Blocks PreK Math Curriculum" (Clements & Sarama, 2007) was designed to facilitate children's engagement in math and talk about math. Much research investigates the effect of curriculum on classrooms or teacher practices. This study used a mediational model to look at a curriculum's effect on children's achievement gain, operating…

The purpose of this study was to examine the relative effects of the single-focus interventions (vocabulary and comprehension) and the streamlined multi-component model. The program of research included a development and pilot phase, an initial experimental study and a follow-up study to further refine and test the model. Results presented here…
