Reviews the results of a meta analysis (E. Deci, R. Koestner, and R. Ryan, 1999) that shows that tangible extrinsic rewards do have a substantial undermining effect on intrinsic motivation. Discusses results, which support cognitive evaluation theory, in terms of their relevance for educational practice. (SLD)

Prior meta analyses by J. Cameron and other researchers suggested that the negative effects of extrinsic reward on intrinsic motivation were limited and avoidable. E. Deci and others (2001) suggested that the analyses were flawed. This commentary makes the case that there is no inherent negative property of reward. (SLD)

Replies to commentary by J. Cameron asserting that the negative results of extrinsic reward on intrinsic motivation are limited and avoidable. Suggests that the most recent meta analysis by Cameron and others shares methodological weaknesses with an earlier analysis, lacking ecological validity. (SLD)

While traditional literature reviews have functioned to clarify a single field, the interpretive review may contribute to research that challenges the perceptual habits of reviewers and extends the ways in which research questions can be constructed and studied. The interpretive review may bring many disciplines together for a new approach to the…

Critiques the conclusions of S. Veenman (1995) about multigrade classes and suggests that selection bias and lower-quality instruction should be included as part of the explanation for his findings of no difference. Indicates that multigrade classes have at least a small negative effect on achievement and potentially negative effects on teacher…

D. Mason and R. Burns (1996) have concluded that multigrade classes have a slightly negative effect on students' achievement. However, a reanalysis, based on meta-analytic procedures, of the available studies shows the average weighted effect sizes to be essentially zero or close to zero. Contains 51 references. (SLD)

Supports the findings of a meta-analysis that demonstrates that student achievement is related to the availability of resources, disagreeing with criticisms of method and sample selection made by E. Hanushek (1996). (SLD)

The analysis by R. Greenwald, L. Hedges, and R. Laine (1996) suffers because of its statistical methods and because it is based on a sample that biases the study toward their conclusions. Econometric evidence and the aggregate performance of U.S. schools points toward serious problems with inefficient use of resources. (SLD)

Asserts that the central problem of the analysis by M. Wang, G. Haertel, and H. Walberg is that they tend to view the teacher, at least implicitly, as the compliant beneficiary of the knowledge of the educational researcher. Any knowledge base that aims to affect classroom practice should take into account and respect the teacher's world.…

Asserts that the reductionistic methodology used by M. Wang, G. Haertel, and H. Walberg in their study does not do justice to the educational phenomena they wish to illuminate. In addition, these authors have too simple a view of the relationship between educational research and educational practice. (SLD)

Asserts that reviews like that of M. Wang, G. Haertel, and H. Walberg are stimulating and useful in thinking about educational research, but they are nearly useless in thinking about educational policy and practice. It is not clear what is meant by "knowledge base," and the finding about proximal and distal variables is simplistic. (SLD)

Asserts that because M. Wang, G. Haertel, and H. Walberg never clarify the contours of their "knowledge base for school learning," it is difficult to know what their broad-based comparison of research studies has really yielded. Explores dilemmas posed by the methodology of the study. (SLD)

Considers the potential impact of the study by M. Wang, G. Haertel, and H. Walberg. Their analysis is the first step in understanding and explaining the factors that really do make a positive difference in quality of school learning, rather than simply describing associations between school-related input and output measures. (SLD)

M. Wang, G. Haertel, and H. Walberg have produced a summary of the bivariate relationships that influence learning. The problem is how to convert such evidence into knowledge, and the knowledge into policy. Discusses how health science provides a guide for making the conversion from evidence to policy. (SLD)

Expresses doubts about whether the evidence presented by M. Wang, G. Haertel, and H. Walberg provides robust and consistent findings that could, or should, be used to inform educational policy and practice. Discusses five questions about the methodology of the study, and indicates that basing educational policy on their findings would be merely an…
