Identifying mathematical interventions that practitioners can implement to improve the mathematical problem solving (PS) of students is a need for the field. Literature on the PS performance of students with disabilities has grown; recently, schema instruction (SI) has been suggested as an evidence-based practice. The purpose of this study was to…

Background: The use of randomised controlled trials (RCTs) in education has increased significantly over the last 15 years. However, their use has also been subject to sustained and rather trenchant criticism from significant sections of the education research community. Key criticisms have included the claims that: it is not possible to undertake…

Ratio and proportional relationships, along with the interrelated topics of fractions,decimals, and percent, provide a critical foundation for algebra (National Mathematics Advisory Panel, 2008). Proportional reasoning, which not only requires understanding the concept of ratios and that two or more ratios are equal, also requires the ability to…

Underlying all What Works Clearinghouse (WWC) products are WWC Study Review Guides, which are intended for use by WWC certified reviewers to assess studies against the WWC evidence standards. As part of an ongoing effort to increase transparency, promote collaboration, and encourage widespread use of the WWC standards, the Institute of Education…

The Programme for International Student Assessment (PISA) assesses the knowledge and skills in mathematics, reading and science of 15-year-old pupils in countries around the world. PISA is run by the Organisation for Economic Co-operation and Development (OECD), and assessment is typically undertaken every 3 years, allowing us to chart how…

The research article is a staple genre in the economy of scientific research, and although research articles have received considerable treatment in genre scholarship, little attention has been given to the important development of Registered Reports. Registered Reports are an emerging, hybrid genre that proceeds through a two-stage model of peer…

This descriptive study focused on identifying types of research conducted in the area of intellectual disability (ID) and published in peer-reviewed journals identified from professional organizations, experts in the field, and databases. The most common research design implemented with IDEA-eligible individuals identified as having ID was single…

This meta-analysis systematically reviewed the most up-to-date literature to determine the effectiveness of reading interventions on measures of word and pseudoword reading, reading comprehension, and passage fluency, and to determine the role intervention and study variables play in moderating the impacts for students at risk for reading…

Researchers sometimes conduct a study and find that the predicted relation between variables did not exist or that the intervention did not have a positive impact on student outcomes; these are referred to as null findings because they fail to disconfirm the null hypothesis. Rather than consider such studies as failures and disregard the null…

Purpose: To conduct a systematic review (SR) of 550 studies produced between 1970 and 2008 that focus on programs and/or services provided by state vocational rehabilitation (VR) agencies believed to impact client and/or program outcomes. Method: Authors used a 5-step SR protocol to evaluate and summarize study content and outcomes, study design,…

Evaluation of academic research plays a significant role in government efforts to steer public universities. The scope of such evaluation is now being extended to include the "relevance" or "impact" of academic research outside the academy. We address how evaluation of non-academic research impact can promote more such impact…

Many randomized experiments in the social sciences allocate subjects to treatment arms at the time the subjects enroll. Desirable features of the mechanism used to assign subjects to treatment arms are often (1) equal numbers of subjects in intervention and control arms, (2) balanced allocation for population subgroups and across covariates, (3)…

Graduate teaching assistants (GTAs) are responsible for direct instruction of geoscience undergraduate students at an array of universities and have a major effect on the knowledge, beliefs, and practices of their students. GTAs benefit from in-department training in both beliefs and practices that align with the existing literature on teaching…

In this paper the authors share their insights on whether it is necessary to articulate a research methodology when reporting on theoretical research. Initially the authors, one being a supervisor and the other, a PhD student and a colleague, were confronted with the question during supervision and writing of a thesis on theoretical research.…

In 2014, I enrolled in a doctoral program within the discipline of Public Health with the aspiration of conducting research on young children's wellbeing as they transition to school. In undertaking a systematic review of the literature on young children's health and wellbeing, it was evident that current conceptualizations of child wellbeing were…
