The field of education is increasingly committed to adopting evidence-based practices. Although randomized experimental designs provide strong evidence of the causal effects of interventions, they are not always feasible. For example, depending upon the research question, it may be difficult for researchers to find the number of children necessary…

The use of educational technology in K-12 classrooms has been gaining tremendous momentum across the country since the 1990s. Many school districts have been investing heavily in various types of technology, such as computers, mobile devices, internet access, and interactive whiteboards. Almost all public schools have access to the internet and…

A search of the ERIC and Academic Search Premier data bases, and a comprehensive review of literature suggest that meta-analysis is ignored by career and technical education (CTE) researchers, a situation that is regrettable but remediable. The purpose of this theoretical paper is to provide CTE researchers and consumers with procedures for…

This article reports a quasi-experimental study on the effects of multimedia teaching and learning in English Literature--a subject which places high cognitive load on students. A large-scale study was conducted in 4 high-achieving secondary schools to examine the differences made to students' learning and performance by the use of multimedia and…

This paper provides a guide to calculating statistical power for the complex multilevel designs that are used in most field studies in education research. For multilevel evaluation studies in the field of education, it is important to account for the impact of clustering on the standard errors of estimates of treatment effects. Using ideas from…

The present review examines research on the effects of technology use on reading achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are investigated to examine the…

The "Read Naturally[R]" program is a supplemental reading program that aims to improve reading fluency, accuracy, and comprehension of elementary and middle school students using a combination of texts, audio CDs, and computer software. The program uses one of four products that share a common fluency-building strategy: "Read…

The purpose of this review is to provide a systematic analysis of studies investigating computer-based interventions (CBI) to improve literacy skills (e.g., reading, writing, and vocabulary) in students with autism spectrum disorders (ASD). This review synthesizes intervention outcomes, appraises the certainty of evidence, and describes software…

"Effectiveness of Reading and Mathematics Software Products: Findings for Two Student Cohorts" examined the effects of ten reading and mathematics software products on student achievement. The study analyzed data on more than 11,000 students in 400 classrooms and was conducted in 23 primarily urban, low-income school districts. The…

Objective: A meta-analysis was conducted to evaluate the effectiveness of solution-focused brief therapy (SFBT). Method: Hierarchical linear modeling software was used to synthesize the primary studies to calculate an overall effect size estimate and test for between-study variability. Results: Solution-focused brief therapy demonstrated small but…

This study compared the effectiveness of self-, other-, and subjective-video models on teaching daily living skills to three individuals with developmental disabilities. Results indicated that all conditions were effective in promoting independent correct responding in both instructional and generalization settings and that the effects maintained…

Describes MINSIZE, an MS-DOS computer program that permits the user to determine the minimum sample size needed for the results of a given analysis to be statistically significant. Program applications for statistical significance tests are presented and illustrated. (SLD)

One current area of dispute in the psychological literature is the inclusion of and proper meta-analytic data analysis procedures for single-subject designs. The current single-subject meta-analysis (N = 25) investigated the effect of time-out for the reduction of disruptive classroom behaviors in nondevelopmentally delayed children. Two separate…

The purpose of this study was to evaluate the instructional effects of using animations, static figures, PowerPoint bulletins, and e-plus software as chemistry texts with the aid of computer-based technology. This study analyzed the characteristics of students involved in three multimedia courses and their achievement and attitude toward chemistry…

Presents use of the effect size as a descriptive statistic for single-subject research. Discusses the way in which effect sizes augment interpretation of results, and reviews four types of treatment effects with case studies. An appendix includes a sample computer program for computing effect sizes. (SLD)
