In paired experiments, participants are grouped into pairs with similar characteristics, and one observation from each pair is randomly assigned to treatment. The resulting treatment and control groups should be well-balanced; however, there may still be small chance imbalances. Building on work for completely randomized experiments, we propose a…

Including students with autism spectrum disorders (ASD) in general education is a common practice today. However, there are relatively few mathematics interventions for students with ASD in secondary education. There is also a lack of literature exploring mathematics interventions that reflect grade-level academic requirements and are adapted for…

This follow-up study presents a design-based research (DBR) setting implemented over a three-year project called 'eKidZ - Teach Your Parents Well' which uses research-based learning and follows the four phases of DBR. In an iterative cycle, 20 teenagers aged 14-16 took on the role of researchers and investigated intergenerational learning and the…

Monitoring the Future (MTF) is an ongoing research program conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated research grants from the National Institute on Drug Abuse beginning in 1975. The integrated MTF study includes annual surveys of nationally-representative samples of 8th, 10th,…

This review protocol guides the review of research that informs the What Works Clearinghouse (WWC) "Assisting Students Struggling with Reading: Intervention in Grade 4-9" practice guide. The review protocol is aligned with the "WWC Procedures and Standards Handbooks Version 4.0." As struggling readers move up the grades, they…

The purpose of this synthesis of literature was to identify and analyze existing research that used experimental or quasi-experimental design in school-based agricultural education. This study utilized published articles in the "Journal of Agricultural Education" from the years 2006 through 2016. The study identified 35 articles that met…

Social skills interventions designed to increase pro-social interactions for individuals with autism spectrum disorders are critical, but the relative effectiveness of these interventions is not well understood. More than 250 single-case design studies in 113 articles were reviewed and described in terms of participants, settings, arrangements,…

This article reports on the design and findings of the first iteration of a classroom-based design research project which endeavours to design a professional development intervention for teachers' mathematical problem-solving pedagogy. The major outcome of this study is the generation of design principles that can be used by other researchers…

The current study investigated the relationship between students' attitudes towards school, values of education, achievement motivation and academic achievement. Accordingly, the study adopted a correlation research design. To achieve the objectives of the study, 362 students using systematic sampling technique were taken from grade 9 students of…

Background: Recent research investigating the conditions under which science teachers can successfully implement science education reforms suggests that focusing only on professional development to improve content knowledge and teaching skills--often referred to as human capital--may not be enough. Increasingly, possessing social capital, defined…

Questions regarding the generalizability of results from educational experiments have been at the forefront of methods development over the past five years. This work has focused on methods for estimating the effect of an intervention in a well-defined inference population (e.g., Tipton, 2013; O'Muircheartaigh and Hedges, 2014); methods for…

Little is known empirically about intraclass correlations (ICCs) for multisite cluster randomized trial (MSCRT) designs, particularly in science education. In this study, ICCs suitable for science achievement studies using a three-level (students in schools in districts) MSCRT design that block on district are estimated and examined. Estimates of…

The goal of the Rural Math Excel Partnership (RMEP) project, a development project funded by the U.S. Department of Education Investing in Innovation (i3) grant program, was to develop a model of shared responsibility among families, teachers, and communities in rural areas as collective support for student success in and preparation for advanced…

Recent federal legislation, such as the "No Child Left Behind Act" of 2001 and the "Education Sciences Reform Act (ESRA)" of 2002, has insisted that educational evaluations use rigorous research designs with quantitative outcome measures. In particular, the Institute of Education Sciences (IES) at the U.S. Department of…

A cluster-randomized trial (CRT) relies on random assignment of intact clusters to treatment conditions, such as classrooms or schools (Raudenbush & Bryk, 2002). One specific type of CRT, a multi-site CRT (MSCRT), is commonly employed in educational research and evaluation studies (Spybrook & Raudenbush, 2009; Spybrook, 2014; Bloom,…
