Policies about reducing class size have been implemented in the US and Europe in the past decades. Only a few studies have discussed the effects of class size at different levels of student achievement, and their findings have been mixed. We employ quantile regression analysis, coupled with instrumental variables, to examine the causal effects of…

This article presents the results of a study examining the highest implementers of the Schools to Watch (STW): School Transformation Network Project, and the impact the project had on their teaching/learning practices and outcomes. The project was funded by the U.S. Department of Education's Investing in Innovation (i3) grant program and was…

This paper estimates the treatment effect of grade repetitions in French junior high schools, using a value-added test score as outcome and quarter of birth as instrument. With linear two-stage least squares, local average treatment effect is estimated at around 1.6 times the standard deviation of the achievement gain. With non-linear…

Research shows a math achievement gap for at-risk and economically-disadvantaged students in the United States. To address this issue, a Texas school district implemented a 90-minute math block-scheduling program with 8th grade students. Shaped by the academic learning time and social justice theories, the purpose of this quantitative program…

The purpose of the study is to investigate the effect of peer support on university level students' English language achievements. An experimental model with pretest-posttest experimental and control group was used with 800 students who were studying at a university in Istanbul vicinity. As experiment group, 400 students (200 of whom…

This descriptive study aimed at finding the impact of Tell Me More (TMM), an online language-learning program, on English as a foreign language (EFL) undergraduate learners' achievement in a University in Thailand. The study also looked at whether the time of use of TMM had an effect on learners' achievement. Data was collected from the scores of…

The purpose of this longitudinal study is to investigate whether an early childhood intervention using an explicit and transparent number naming system will have a lasting benefit to English and Spanish speaking children in their mathematics achievement related to number sense by accelerating their acquisition of concepts of numeracy and place…

In this study, the effect of the learning together technique, which is one of the cooperative learning methods, on the development of the listening comprehension and listening skills of the secondary school eighth grade students was investigated. Regarding the purpose of the research, experimental and control groups consisting of 75 students from,…

This study investigates school effects on primary school students' language and mathematics achievement trajectories in Chile, a context of particular interest given its large between-school variability in educational outcomes. The sample features an accelerated longitudinal design (3 time points, 4 cohorts) together spanning Grades 3 to 8…

Helping struggling readers to learn history content in middle school can be difficult due to heavy reading demands. In this study, researchers taught poor readers with and without disabilities in eighth grade to generate main idea statements; create, compare, and contrast paragraphs; and identify cause and effect relations, along with relevant…

Enhancing all students' academic performance continues to be a national priority, and although achievement gains have been made overtime, shortfalls in mathematics learning for students with disabilities (SWD) remain. Research reveals that a substantial portion of the variability in students' mathematics achievement gains is due to the teacher. To…

Many states have implemented or expanded state-funded prekindergarten programs in the last decade, encouraged by claims about the benefits that can be expected and the importance of early experiences for children's development, especially for economically disadvantaged children. However, there is remarkably little methodologically adequate…

This study investigated the achievement of south Texas public school fifth graders participating in gifted and talented programming compared to the achievement of fifth graders not participating in gifted and talented classification in the area of math to determine if any differences exist. Student achievement of males and females and students…

For many years, changing beliefs has been considered a prerequisite for changing classroom practices. However, professional development research has also shown that the opposite relationship is also true--change in practice can precede change in beliefs. This study investigated the effect of a one-year professional development program on…
