While research on the relationship between general education class size and student achievement is plentiful, research on class size in special education is scarce, even though class size issues must be considered particularly important to students with special educational needs. This summary is based on a systematic review that sought to examine…

This is the protocol for a Campbell review. The objective of this systematic review is to uncover and synthesise data from studies to assess the impact of small class sizes on the academic achievement, socioemotional development, and well-being of students with special educational needs. Where possible, we will also investigate the extent to which…

While process simulation tools offer immense potential in chemical engineering, effectively integrating them into the educational curriculum poses challenges. This work explored and practiced online-offline blended teaching in process simulation courses. The design of this blended course was based on a comparison of students' performances in fully…

Reducing class size is seen as a way of improving student performance. But larger class sizes help control education budgets. The evidence suggests at best a small effect on reading achievement. There is a negative, but statistically insignificant, effect on mathematics, so it cannot be ruled out that some children may be adversely affected. This…

"Imparting Wisdom: HBCU Lessons for K-12 Education" details historically black colleges and universities' (HBCUs) longstanding efforts to provide quality educational experiences for their students and how their success may be translated in K-12 schools. This brief uplifts research-based HBCU best practices, practical recommendations and…

With few exceptions, empirical research investigating the possibility of heterogeneous benefits of class size reduction lacks a conceptual framework about specific dimensions of potential heterogeneity. In this paper we develop a model of education production that incorporates disruption and student achievement and illustrates how these underlying…

Does reduced class size cause higher academic achievement for both Black and other students in reading, mathematics, listening, and word recognition skills? Do Black students benefit more than other students from reduced class size? Does the magnitude of the minority advantages vary significantly across schools? This article addresses the causal…

Do smaller classes boost achievement mainly by helping teachers impart specific academic skills to students with low academic achievement? Or do they do so primarily by helping teachers engage poorly behaving students? The analysis uses the grade 3 to 4 transition in San Diego Unified School District as a source of exogenous variation in class…

During summer vacation, many students lose knowledge and skills. By the end of summer, students perform, on average, one month behind where they left off in the spring. Participation in summer learning programs should mitigate learning loss and could even produce achievement gains. Indeed, educators and policymakers increasingly promote summer…

This article describes a multifaceted program that improves the mathematics instruction in a school district's 10 lowest-performing schools. This program includes seven support components--including monetary incentives for teachers, professional development, education technology, and reduced class sizes. After three years, results show that the…

Much of the economic education literature suggests that the principles of economics class size does not significantly affect student performance. However, study methods have varied in terms of the aggregation level (student or class), the measure of performance (TUCE or course letter grade), and the class size measure (e.g., students who completed…

Distressed by their students' reading failure rate, teachers at two Georgia schools developed a parallel block-scheduling plan that allows for whole-class instruction, direct-instruction miniclasses, and enrichment labs for all students. Success depends on matching creative, resourceful teachers to the enrichment lab positions. Over the past two…

SAGE is a five-year class-size-reduction program being implemented in 80 Wisconsin schools. A longitudinal, evaluative study is being conducted in 30 SAGE schools. Small classes have three effects leading to increased individualization: fewer discipline problems, greater knowledge of students, and more teacher enthusiasm (using directive methods).…

This study provides an overview of class size research, examples of various class size and pupil-teacher-ratio (PTR) configurations commonly used by practitioners, and the most recent findings of scientifically controlled experimental Tennessee STAR studies. The learning environment is hierarchical in nature, with student-level data influenced by…

Before a St. Louis (Missouri) school could raise student achievement, its principal had to break through several "false ceilings" to create a new standard of student performance. To achieve this goal, the principal refrained from underestimating her "at-risk" students, provided enrichment instead of remediation programs,…
