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…

Good practice in primary research has evolved over many decades of research in applied linguistics to counter human fallibility and biases. Surprisingly, perhaps, synthesising such research in an entire field has only recently started to develop its own methodologies and recommendations. This paper outlines some of the issues involved, especially…

Any research study can only be fully appreciated once it is situated in relation to existing work. This is no mean feat, however, given the sheer quantity and variety of publications to date. Simply relying on one's background and experience as an expert in the field, coupled with a few internet searches and following up individual references, is…

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…

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…

Meta-analytic methods are often used to determine the effectiveness of certain treatments across studies. However, we are often unaware of how a meta-analysis can provide value to researchers and practitioners. This paper offers a brief commentary on a meta-analysis conducted by Lin, Huang and Liou (2013) in LLT, providing further statistical…

This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test score quality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels. Results indicate that (a) computer-based scaffolding positively…

As Information Technology expands, all industries and fields in Saudi Arabia are experiencing reduced costs and improvements in the efficiency and effectiveness of operations in various systems. This has positioned the higher education sector in Saudi Arabia as the land of opportunity in terms of educational technology and its ability to support…

The aim of the current study is to determine the overall effects of Computer-Assisted Mathematics Education (CAME) on academic achievement. After an extensive review of the literature, studies using Turkish samples and observing the effects of Computer-Assisted Education (CAE) on mathematics achievement were examined. As a result of this…

This study examines (1) the effects of hypertext gloss use on L2 vocabulary acquisition in computerized reading contexts; (2) which specific combination of either text-only (single) or text + visual (multiple) hypertext glosses is more effective on L2 vocabulary acquisition; and (3) potential moderators to systematically account for between study…

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,…

This paper presents a comprehensive picture of what has been investigated in terms of CALL effectiveness over the period 1981-2005 throwing light on why this question is still such a difficult one to answer unequivocally. The author looks at both strengths and weaknesses in this body of work, highlighting pitfalls and paradoxes in research…

Many primary studies have been performed to reveal the effects of computer assisted instruction (CAI) on students' attitudes towards science courses. In determining the effectiveness of these studies, gathering and evaluating of the studies at some characteristics play an important role. The aim of this study is to determine meta-analytically the…

The meta-analysis of 22 studies on the effectiveness of computer assisted instruction (CAI) with exceptional children indicated that most studies reported CAI to be largely effective but that the result of calculating effect sizes indicated a moderate effect for CAI. (Author/DB)

This meta analysis examines the effect of computer-assisted instruction (CAI) upon college student performance, addresses the impact of various study characteristics upon effects, and explores how media richness theory may predict CAI performance gains. Findings indicate that student performance gains are larger for CAI than traditional…
