This research study employs a second-order meta-analysis procedure to summarize 40 years of research activity addressing the question, does computer technology use affect student achievement in formal face-to-face classrooms as compared to classrooms that do not use technology? A study-level meta-analytic validation was also conducted for purposes…

This meta-analysis of the experimental literature of distance education (DE) compares different types of interaction treatments (ITs) with other DE instructional treatments. ITs are the instructional and/or media conditions designed into DE courses, which are intended to facilitate student-student (SS), student-teacher (ST), or student-content…

Critical thinking (CT), or the ability to engage in purposeful, self-regulatory judgment, is widely recognized as an important, even essential, skill. This article describes an ongoing meta-analysis that summarizes the available empirical evidence on the impact of instruction on the development and enhancement of critical thinking skills and…

A meta-analysis of the comparative distance education (DE) literature between 1985 and 2002 was conducted. In total, 232 studies containing 688 independent achievement, attitude, and retention outcomes were analyzed. Overall results indicated effect sizes of essentially zero on all three measures and wide variability. This suggests that many…

Synthesized the empirical research on the effects of social context (small group versus individual learning) when students learn using computer technology. Analyzed 486 independent findings from 122 studies involving 11,317 learners. On average, small group learning had more positive effects, but findings on both individual achievement and group…

Six quantitative reviews of the research on student ratings of instructional effectiveness are examined. The disparate conclusions of the reviews are explained by comparing the syntheses at each of five steps in a meta-analysis: specifying inclusion criteria; locating studies; coding study features; calculating study outcomes; and data analysis.…

A common criticism of student ratings of instruction is that they are affected by the personal style of the instructor rather than an instructor's ability to convey instructional material. It was found that instructor expressiveness had a substanial impact on student ratings but a small impact on student achievement. (Author/PN)
