I describe how a policy aimed at increasing achievement among students labeled EL initially went awry--and how a researcher-district partnership persevered to rectify it. The policy, which called for 100% EL classrooms, produced unintended consequences. Critical discussion of empirical evidence and district-solicited input from multiple…

This study investigates the impact of the presence of students identified as having special needs (SEN) on their classmates' achievements in reading comprehension. Multi-level regression modelling was conducted with the data of more than 75,000 fourth graders of 4,937 classes in Austria. Students' scores of reading comprehension were used as the…

According to dimensional comparison theory (DCT), students evaluate their ability in one domain (e.g., math) by comparing their achievement in that domain with their achievement in other domains (e.g., English). Primarily in research on students' academic self-concept, these comparison processes have been found to lead to positive associations…

Students' executive functions (EFs) are linked to school success. Although school-age children spend much of their time interacting with peers, few studies have explored how children's classmates may promote EF development in elementary school. In this study, we test whether mean levels and variability in classmates' EF skills are associated with…

This study evaluates the effects of classroom peers on standardized testing achievement for all third- and fourth-grade students in the Philadelphia School District over 6 school years. With a comprehensive individual-and multilevel data set of all students matched to teachers, classrooms, and schools, two empirical strategies are employed. The…

In this paper, we assume that students' achievement is influenced not only by a set of individual appraisals such as beliefs about their personal efficacy but also by a set of more systemic factors related to beliefs about their class efficacy as a group. Literature and research review supports that students' beliefs about their efficacy, both as…

The purpose of the study was to measure the effects of higher level, inquiry-based science curricula on students at primary level in Title I schools. Approximately 3,300 K-3 students from six schools were assigned to experimental or control classes (N = 115 total) on a random basis according to class. Experimental students were exposed to…

This paper estimates the causal effect of taking a course in quantitative reasoning on students' academic performance and classroom peer-group composition at a liberal arts college. To identify effects, the paper compares the outcomes of otherwise similar students who barely passed a baseline quantitative skills assessment (not taking the course)…

In this study done at a community college in South Florida, the achievements of students who spoke English as their second language who had attended their K-12 education outside the United States in their home countries, in a U.S. college course on world geography are compared with the achievements of students in the same classes who spoke English…

As education continues to progress schools are constantly seeking innovative ways to cultivate and enhance achievement for all students. As a result many public schools are pushing toward the inclusion model. This model includes co-taught instruction to meet the many needs of special education students. This research study was implemented to…

High schools that enable educators to nurture the distinctive interests and talents of all groups of students can help more students stay in school and find the motivation to prepare for college and careers. By implementing six clear-cut ideas, or conditions, that evidence shows can lead more students to success, schools and communities can…

This paper develops a model for longitudinal student achievement data designed to estimate heterogeneity in teacher effects across students of different achievement levels. The model specifies interactions between teacher effects and students' predicted scores on a test, estimating both average effects of individual teachers and interaction terms…

Background/Context: Considerable controversy surrounds the issue of whether high-stakes statewide accountability programs have led to more equitable educational opportunities for all students. Some researchers suggest that these programs have focused attention on improving the achievement of students of color from low socioeconomic backgrounds.…

This report examines the path to college for students in academically advanced programs-- graduates of Chicago's seven Selective Enrollment schools, those who completed International Baccalaureate programs, and graduates who had taken a sequence of at least six honors and two Advanced Placement classes. This report expands on the findings of…

This document discusses the author's solution to students' demands for smaller, more individual classes vs. administrative pressure, forced by enrollment and financial demands, for larger classes. In the 1970 fall semester at Cypress College (California) 150 students participated in an experiment in which an economics 1A class size was increased…
