Active learning pedagogical practices are more effective than instructor-centered teaching in building students' knowledge, skills, and understanding of engineering content and concepts. As such, a large-scale professional development (PD) program was created to move faculty toward the use of active learning. The project aimed to engage faculty in…

In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized…

Increasing class size is one of the key variables that policy makers can use to control spending on education. But the consensus among many education researchers is that smaller classes are effective in improving student achievement. This view has led to a policy of class size reductions in a number of US states, the UK, and the Netherlands. This…

National assessments have shown that the majority of students in the United States cannot read at grade level by fourth grade. These results are alarming because students who are not proficient readers by third grade suffer long-term consequences and are more likely to drop out of high school. Feeling pressure to improve reading outcomes, schools…

Most evaluations of education policies focus on their mean impacts; when distributional effects are investigated it is usually by comparing mean impacts across demographic subgroups. We argue that such estimates may overlook important treatment effect heterogeneity; in order to appreciate the full extent of a policy's distributional impacts one…

Background: Class size reduction (CSR) is an enduring school reform undertaken in an effort to improve academic achievement and has been widely encouraged in the United States. Supporters of CSR often cite the positive contemporaneous and carryover effects of Project STAR. Much has been discussed regarding the robustness of the contemporaneous…

"Reconnecting Youth" is an elective, credit-bearing course for students at risk of dropping out of school due to frequent absenteeism, low grades, or a history of dropping out. The curriculum focuses on building self-esteem, decision making, personal control, and interpersonal communication skills. The What Works Clearninghouse (WWC)…

Schools across the United States are facing budgetary pressures on a scale not seen in generations. Times of fiscal exigency force policymakers and education practitioners to pay more attention to the return on various categories of public investment in education. The sizes of the classes in which students are educated are often a focus of these…

Although the use of clickers and peer discussion is becoming common in large-lecture undergraduate biology courses, their use is limited in small-enrollment seminar-style courses. To investigate whether facilitating peer discussion with clickers would add value to a small-enrollment seminar-style course, we evaluated their usefulness in an…

Evidence from Project STAR has suggested a considerable advantage of being in small classes in early grades. However, the extra benefits of additional years in small classes have not been discussed in detail. The present study examined the additional effects of being in small classes for more than 1 year. We find that once previous grade…

This Information Capsule examines the background and history in addition to research findings pertaining to class size reduction (CSR). This Capsule concludes that although educational researchers have not definitively agreed upon the effectiveness of CSR, given its almost universal public appeal, there is little doubt it is here to stay in some…

Public education in the United States struggles to prepare all students for success in post-secondary education and careers. One reason attributed to dropouts, student-disconnect, and low levels of achievement is that too many students attend large, impersonal schools where they are not engaged in learning. Many policy makers view the…

"Everyone Playing in Class" is an unstructured free play based provision for small classes or groups. The intervention involves training staff in attachment theory, presenting up-to-date research findings on the role of play in emotional well-being and relationship building, as well as teaching reflective communication skills. In this…

The researcher conducted a nonexperimental study to investigate and analyze the influence of reduced class sizes, intensity (all day and every day), duration (five years), and heterogeneity (random class assignment) on the Head Start Fade effect. The researcher employed retrospective data analysis using a longitudinal explanatory design on data…

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…
