The purpose of this study is to investigate the effects of laboratory approach based on jigsaw method with cooperative learning and confirmatory laboratory approach on university students' cognitive process development in Science teaching laboratory applications, and to determine the opinions of the students on applied laboratory methods. The…

This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

In this paper the authors extend recent work on mediation in a multilevel setting and on causal inference under interference among units to develop a template for the mediation analysis of group randomized educational interventions. The present work will contribute to the literature on interference, in particular on interference in the context of…

The Louisiana Scholarship Program (LSP) is a statewide initiative offering publicly-funded vouchers to enroll in local private schools to students in low-performing schools with family income no greater than 250 percent of the poverty line. Initially established in 2008 as a pilot program in New Orleans, the LSP was expanded statewide in 2012.…

Randomized trials of educational interventions often face logistical hurdles (Cook, 2002). For example, sometimes they are prevented from reaching their full-term. This would happen if, as a condition of participation, subjects insist on receiving the treatment program within a certain timeframe. This timeframe may be shorter than the full-term…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

Despite impressive advances in the science of reading intervention, how to best help at-risk readers remains a point of contention. Because reading represents the synthesis of background factors and language and reading skills--all of which develop with age and experience--this meta-analysis investigated whether development (as approximated by…

This article provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions. The article (a) provides new empirical information about the values of parameters that influence the precision of impact estimates (intraclass correlations and R[superscript 2] values) and…

This report addresses the following four questions by reporting on the impacts of Head Start on children and families during the children's preschool, kindergarten, and 1st grade years: (1) What difference does Head Start make to key outcomes of development and learning (and in particular, the multiple domains of school readiness) for low-income…

The present study investigated the efficacy of using response cost paired with Differential Reinforcement of Incompatible Behavior (DRI) to manage the inattentive behavior of 30 students attending third and fourth grade in Jordan. A pretest-posttest control group design was employed to evaluate the efficacy of response cost and DRI. Results showed…

Background: This study evaluated the impact on student's writing ability of a structured writing program, called "Writing Wings," for 3rd, 4th, and 5th graders developed by the Success For All Foundation (SFAF). Writing is a critical skill for success in school. Purpose: The study was intended to answer one confirmatory question,…

Social promotion has long been the normal practice in American schools. Critics of this practice, whereby students are promoted to the next grade regardless of academic preparation, have suggested that students would benefit academically if they were made to repeat a grade. Supporters of social promotion claim that retaining students disrupts them…
