Often it is infeasible or unethical to use random assignment in educational settings to study important constructs and questions. Hence, educational research often uses observational data, such as large-scale secondary data sets and state and school district data, and quasi-experimental designs. One method of reducing selection bias in estimations…

This paper shows how the application of simple statistical methods can reveal to students important insights from climate data. While the popular press is filled with contradictory opinions about climate science, teachers can encourage students to use introductory-level statistics to analyze data for themselves on this important issue in public…

Overlap-based measures are increasingly applied in the synthesis of single-subject research. This article considers two criticisms of overlap-based metrics, specifically that they do not measure magnitude of effect and do not adequately correspond with visual analysis. It is argued that these criticisms are based on fundamental misconceptions…

Data mining is concerned with detecting patterns of data in raw datasets, which are then used to unearth knowledge that might not have been discovered using conventional querying or statistical methods. This discovered knowledge has been used to empower decision makers in countless applications spanning across many multi-disciplinary areas…

Assistive technology (AT) has been identified as one of the most effective interventions for rehabilitation purposes of individuals with disabilities. Due to the positive potentials, assistive technology has attracted tremendous attention among the rehabilitation counselors during the past decades. As a result, numerous AT devices have been…

"Beginning Interpretive Inquiry" importantly makes the distinction between the use of "inquiry" rather than interpretive research or interpretive evaluation. Richard Morehouse explores how inquiry is a far more inclusive concept that allows for a detailed understanding of both research and evaluation. The author draws on his personal experiences…

The study explored instructional benefits of a storyline gaming characteristic (GC) on learning effectiveness, efficiency, and engagement with the use of an online instructional simulation for graduate students in an introductory statistics course. A storyline is a game-design element that connects scenes with the educational content. In order to…

The study examined the connection between writing competency and writing feedback experiences through academic writing course for student-teachers across the curriculum. The aims of the course were to prepare student-teachers to their role as writing facilitators and to improve their writing. Experimental and control group differed in course plan…

This research was undertaken to determine if significant relationships exist between teachers' self-reported attitudes, concerns, and efficacy to teach in inclusive classrooms and their actual classroom behaviour in Winnipeg, Canada. Five teachers completed 3 scales measuring their attitudes to inclusion, their level of concerns about teaching in…

Although previous research has explored the efficacy of differential response (DR) programs in child welfare, there have been no studies to date about coding decisions between designations by child protection service agencies. Research has explored client satisfaction with DR as well as rates of recidivism and removal/placement but with limited…

This quantitative study of South Carolina middle school principals investigated how these principals use data in decision making. The P3DMI developed by Childress (2009) was incorporated into the survey to evaluate the role data plays in four areas of leadership for these principals: 1) school vision, 2) school instruction, 3) school organization,…

Adjusted Wald intervals for binomial proportions in one-sample and two-sample designs have been shown to perform about as well as the best available methods. The adjusted Wald intervals are easy to compute and have been incorporated into introductory statistics courses. An adjusted Wald interval for paired binomial proportions is proposed here and…

Nowadays more and more modern medical degree programs focus on self-directed and problem-based learning. That requires students to search for high quality and easy to retrieve online resources. YouTube is an emerging platform for learning human anatomy due to easy access and being a free service. The purpose of this study is to make a quantitative…

This paper presents evidence on the amount of classroom variation in gains across various domains of achievement within the Tennessee Voluntary Pre-Kindergarten (TN-VPK) program; the data are taken from the randomized control trial (RCT) design of the TN-VPK evaluation. This study explores areas where those differences are largest, and offers…

Background: Prior research has shown that students taught using "Standards"-based mathematics curricula tend to outperform students on measures of mathematics achievement. However, little research has focused particularly on the promotion of student quantitative literacy (QLT). In this study, the potential influence of the…
