This study takes a design-based research approach to explore how applications designed for mobile devices could support reflection in learning in K-12 education. Use of mobile devices is increasing in schools. Most of the educational apps support single-person use of interactive learning materials, simulations and learning games. Apps designed to…

Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

The Institute of Education Sciences has funded more than 100 experiments to evaluate educational interventions in an effort to generate scientific evidence of program effectiveness on which to base education policy and practice. In general, these studies are designed with the goal of having adequate statistical power to detect the average…

Evaluators must employ research designs that generate compelling evidence related to the worth or value of programs, of which assessment data often play a critical role. This article focuses on assessment design in the context of evaluation. It describes the process of using the Framework for K-12 Science Education and Next Generation Science…

As evidence becomes increasingly important in educational policy, it is essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. A total of 645 studies from 12 recent reviews of evaluations of preschool, reading, mathematics, and science programs were studied. Effect…

Professional development programs are based on different theories of how students learn and different theories of how teachers learn. Reviewers often sort programs according to design features such as program duration, intensity, or the use of specific techniques such as coaches or online lessons, but these categories do not illuminate the…

In this study, methodology and theory were linked to explicate the nature of education practice within schools facing exceptionally challenging circumstances (SFECC) in Trinidad and Tobago. The research design was an iterative quan>QUAL-quan>qual multi-method research programme, consisting of 3 independent projects linked together by overall…

Targeting students in grades K-8, Art in Action's program consists of 12 age-appropriate lessons per year led by parent and teacher volunteers. The curriculum is based on historically significant artists and their works of art. Through semi-structured discussions, students examine a variety of masterpieces, learning about the artist as well as…

Much is known about how to improve students' comprehension when reading printed text; less is known about outcomes when reading digital text. The purpose of this meta-analysis was to analyze research on the impact of digital text interventions. A comprehensive literature search resulted in 27 group intervention studies with 16,513 participants.…

We conducted a systematic review of the evidence related to online instruction in writing for students with special needs with the purpose of determining whether the existing literature can provide a research base and responding to special education researchers' concerns about students with disabilities receiving instruction online. We identified…

School personnel make a variety of decisions within multitiered problem-solving frameworks, including the decision to assign a student to group-based support, to design an individualized support plan, or classify a student as eligible for special education. Each decision is founded upon a judgment regarding whether the student has responded to…

The aim of this study is to address and analyse pre-service teachers' mathematical reasoning skills in relation to mathematical thinking processes. For these purposes, pre-service teachers' mathematical reasoning skills namely generalising/abstraction/modelling, ratiocination, development and creative thinking skills and the relationships among…

This systematic descriptive historical review was conducted to examine the status and trends in expository text structure instruction efficacy research for first through twelfth grade students. The analysis included sixty studies, which spanned the years 1978 to 2014. Descriptive dimensions of the research included study type, research design,…

The Council for the Accreditation of Educator Preparation (CAEP) requires faculty from educator preparation programs to provide evidence of credential candidates' impact on K-12 student learning. However, there is a paucity of information on preparation programs' use of direct assessments of student learning to gauge credential candidate…

This article provides a quantitative synthesis of the published literature on word problem solving intervention studies for children with math disabilities (MD). Seven group and eight single-subject design studies met inclusion criteria. Mean effect sizes ("ES"s) for solution accuracy for group design studies were 0.95 (SE = 0.19) for…
