The evaluation of intervention effects is an important objective of educational research. One way to evaluate the effectiveness of an intervention is to conduct an experiment that assigns individuals to control and treatment groups. In the context of pretest/posttest designed studies, this is referred to as a control-group pretest/posttest design.…

Junior enlisted Marines are getting married at a faster rate than their civilian counterparts and nearly twice that of senior personnel (Gomulka, 2010; Cohen, Passel, Wang, & Livingston, 2011). With the high rate of marriage, these same junior Marines have a disproportionately high divorce rate. While the high rate of divorce is a significant…

The present article considers a fundamental question in evaluation research: "By how much do program effects vary across sites?" The article first presents a theoretical model of cross-site impact variation and a related estimation model with a random treatment coefficient and fixed site-specific intercepts. This approach eliminates…

In the past decades, various systems have been proposed to provide students with a better learning environment by taking personal factors into account. Learning styles have been one of the widely adopted factors in the previous studies as a reference for adapting learning content or organizing the content. However, very few researchers give an…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

This paper is the first summary of two studies and 10 years of evaluating the Milwaukee Parental Choice (voucher) Program (MPCP). This paper discusses school voucher evaluations in general terms and how these studies are carried out. The paper outlines the types of studies completed in "Study I" and "Study II" and the results…

In an effort to bring rigorous research into the education and social sciences field, the past decade had seen an increase in the advocacy of randomized controlled trials. The argument in favor of using randomized controlled trial is that one can evaluate the impact of an intervention in comparison to a control group with confidence during a…

Purpose: The past decade has seen considerable debate about how to best evaluate the efficacy of educational improvement initiatives, and members of the educational leadership research community have entered the debate with great energy. Throughout this debate, the use of randomized experiments has been a particularly contentious subject. This…

Using exogenous characteristics to identify endogenous subgroups, the approach discussed in this method note creates symmetric subsets within treatment and control groups, allowing the analysis to take advantage of an experimental design. In order to maintain treatment--control symmetry, however, prior work has posited that it is necessary to use…

Background: In elementary grades, comprehensive health education curricula have demonstrated effectiveness in addressing singular health issues. The Michigan Model for Health (MMH) was implemented and evaluated to determine its impact on nutrition, physical fitness, and safety knowledge and skills. Methods: Schools (N = 52) were randomly assigned…

Personalized e-learning implementation is recognized as one of the most interesting research areas in the distance web-based education. Since the learning style of each learner is different one must fit e-learning with the different needs of learners. This paper presents an approach to integrate learning styles into adaptive e-learning hypermedia.…

Implementation of the standards established by the Higher Education Council (HEC) has shown great variation between universities, between departments and even between supervisors. A TUBITAK (111K162)-EVRENA project designed to develop a "teaching practice program" using a Clinical Supervision Model (CSM) was conducted. The present study…

Improvement of teachers' content knowledge has long been regarded as a priority in Indonesian school systems, and has been the goal for many teacher professional development programs. In this paper we report the evaluation of a professional development program to improve content knowledge for 147 Indonesian teachers. The teachers were divided into…

Success for All (SFA), one of the best-known school reform models, aims to improve the reading skills of all children but is especially directed at schools that serve large numbers of students from low-income families. First implemented in 1987, SFA combines a challenging reading program, whole-school reform elements, and an emphasis on continuous…
