This multiple paper dissertation addressed several issues revolving around the estimation of effect sizes for computer-based scaffolding in problem-centered STEM education. STEM jobs are outpacing all other jobs and STEM workers are expected to solve complex problems. However, students often struggle with complex problem activities. Research on…

Background/Context: Many students in the United States need access to effective writing instruction, with some requiring intensive intervention. Results from the National Assessment of Education Progress (NAEP) in writing over the past 25 years revealed that most students in the U.S. have yet to attain a proficient level of written expression…

This review describes a meta-analysis of findings from 50 controlled evaluations of intelligent computer tutoring systems. The median effect of intelligent tutoring in the 50 evaluations was to raise test scores 0.66 standard deviations over conventional levels, or from the 50th to the 75th percentile. However, the amount of improvement found in…

In the current document, an integrative CBT-TTF framework is created, which proposes: technologies that require large amounts of working memory are best at improving outcomes that require little working memory to develop, and vice versa. Then, a meta-analysis of virtual reality (VR) training programs (which require great amounts of working memory)…

Based on screenings of 1,150 manuscripts, we synthesize evidence from 18 eligible studies of educational interventions implemented within juvenile correctional facilities. The studies include 5 intervention categories: remedial academic instruction, computer-assisted instruction, personalized academic instruction, vocational education, and GED…

Teaching with technology is considered a necessity in the U.S. mathematics classroom. However, few studies have established explicit considerations to support technology-enhanced student achievement. The purpose of this study was to characterize the effectiveness of technology in the mathematics classroom by systematically reviewing meta-analytic…

Computer-assisted learning is known to be an effective tool for improving learning in both adults and children. Recent years have seen the emergence of the so-called "serious games (SGs)" that are flooding the educational games market. In this paper, the term "serious games" is used to refer to video games (VGs) intended to serve a useful purpose.…

The Second Chance Act of 2007 (Public Law 110-199) represented a historic piece of legislation designed to improve outcomes for and provide a comprehensive response to the increasing number of individuals who are released from prisons, jails, and juvenile residential facilities, and returning to communities upon release. The Second Chance Act's…

This review examines the effectiveness of educational technology applications in improving the reading achievement of struggling readers in elementary schools. The review applies consistent inclusion standards to focus on studies that met high methodological standards. A total of 20 studies based on about 7,000 students in grades K-6 were included…

This review examines research on the effects of technology use on reading achievement in K-12 classrooms. It applies consistent inclusion standards to focus on studies that met high methodological standards. A total of 84 qualified studies based on over 60,000 K-12 participants were included in the final analysis. Four major categories of…

Although previous meta-analyses have documented the efficacy of computer-assisted statistics instruction, the current study examined a range of specific features that presumably influence its effectiveness, such as the level of learner engagement, learner control, and the nature of feedback. In 45 experimental studies with a control condition,…

The purpose of this review is to learn from rigorous evaluations of alternative technology applications how features of using technology programs and characteristics of their evaluations affect reading outcomes for students in grades K-12. The review applies consistent inclusion standards to focus on studies that met high methodological standards.…

Studies focusing on the effectiveness of computer-assisted instruction have been growing recently in Turkey. In this research, quantitative studies comparing the effectiveness of computer-assisted instruction to traditional teaching method and conducted between 1998 and 2007 are studied by meta analysis. Seventy eight studies that have eligible…

This article reviews research on the achievement outcomes of three types of approaches to improving elementary mathematics: mathematics curricula, computer-assisted instruction (CAI), and instructional process programs. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least 12 weeks, and…
