This meta-analysis synthesizes research on the effectiveness of intelligent tutoring systems (ITS) for college students. Thirty-five reports were found containing 39 studies assessing the effectiveness of 22 types of ITS in higher education settings. Most frequently studied were AutoTutor, Assessment and Learning in Knowledge Spaces, eXtended…

This research synthesis examined the impact of grades, comments, and no performance feedback on academic motivation and achievement in elementary and secondary school. Four meta-analyses were conducted, with two each exploring the impact of (a) grades versus no performance feedback and (b) grades versus comments on academic motivation and…

In this study, we meta-analyzed empirical research of the effectiveness of intelligent tutoring systems (ITS) on K-12 students' mathematical learning. A total of 26 reports containing 34 independent samples met study inclusion criteria. The reports appeared between 1997 and 2010. The majority of included studies compared the effectiveness of ITS…

The "assessment 'for' learning" movement in education has increased attention to self-grading and peer-grading practices in primary and secondary schools. This research synthesis examined several questions pertaining to the use of self-grading and peer-grading in conjunction with criterion-referenced testing in 3rd- through…

A complete description of the literature search, including the criteria used for the inclusion of reports after they have been located, used in a research synthesis or meta-analysis is critical if subsequent researchers are to accurately evaluate and reproduce a synthesis' methods and results. Based on previous guidelines and new suggestions, we…

Opinions vary on whether or not homework has positive effects on achievement. In the literature, the author found six studies conducted between 1987 and 2003 that compared homeworkers with no-homeworkers, and equated students by using either: (1) random assignments of students to conditions; or (2) statistical controls or by matching a student in…

A meta-analysis found that attending full-day (or all-day) kindergarten had a positive association with academic achievement (compared to half-day kindergarten) equal to about one quarter standard deviation at the end of the kindergarten year. But the association disappeared by third grade. Reasons for this fade-out are discussed. Social…

New emphasis is being placed on the importance of parent involvement in children's education. In a synthesis of research on the effects of parent involvement in homework, a meta-analysis of 14 studies that manipulated parent training for homework involvement reveals that training parents to be involved in their child's homework results in (a)…

Questions repeatedly arise about whether evaluations of research papers are systematically influenced by factors unrelated to quality, such as gender or prestige of the authors or reviewers. This study examined the reliability of reviews of proposals submitted for inclusion in the 1984 American Educational Research Association annual meeting…

The process of research synthesis is examined in this paper. The results of a case study of what happens to the attitudes of six experts in the field of school desegregation and black achievement when they interactively review the relevant research literature are presented. The impact of these subjects' resulting reviews on the attitudes of a less…

A taxonomy for literature reviews in education and psychology is presented. The increased use of the descriptor "literature review" in ERIC and Psychological Abstracts documents between 1969 and 1983 is cited as creating the need for categorization. The taxonomy categorizes reviews according to focus, goal, perspective, coverage,…

Theoretical and practical implications of the proposition that teachers' differential behavior toward high and low expectation students serves a control function were tested. As predicted, initial performance expectations were found related to later perceptions of control over performance, even when the initial relationship between expectations…

The concept that teacher beliefs about future student achievement may actually influence the subsequent performance of students provides the basis for a model of teacher expectation communication which uses attribution theory as explanatory links in the communication process. These model links were tested in a two-year study involving 16 third-,…

The effects of record-card-type information on performance expectations were examined. Expectations based solely on preobservational information (standardized tests, previous teachers, family, physical characteristics) were positively related to the quality of the reported performance. Implications for the public concern over record card…

In a study of academic attribution patterns, teachers were asked to suggest causes for the successes and failures of students whose backgrounds had been manipulated to provide various combinations of social class (middle, lower), race (White, Asian American), and gender. It was found that teachers cited causes internal to the student more often…
