Past research has shown student-teacher relationships (STRs) are associated with student outcomes, including improvements in academic achievement and engagement and reductions in disruptive behaviors, suspension, and risk of dropping out. Schools can support STRs universally and systematically by implementing universal, school-wide, and class-wide…

This meta-analysis examined if students' writing performance is improved by reading interventions in studies (k = 54 experiments; 5,018 students) where students were taught how to read and studies (k = 36 investigations; 3,060 students) where students' interaction with words or text was increased through reading or observing others read. Studies…

A variety of instructional practices have been recommended to increase the problem-solving (PS) performance of elementary school children. The purpose of this meta-analysis was to systematically review research on the use of schema instruction to increase the PS performance of elementary school-age students. A total of 21 studies, with 3,408…

The National Science Foundation-sponsored report "Fostering Learning in the Networked World" called for "a common, open platform to support communities of developers and learners in ways that enable both to take advantage of advances in the learning sciences." We review research on science inquiry learning environments (ILEs)…

The current review addresses the validity of published meta-analyses in education that determines the credibility and generalizability of study findings using a total of 56 meta-analyses published in education in the 2000s. Our objectives were to evaluate the current meta-analytic practices in education, identify methodological strengths and…

This systematic review of algebra instructional improvement strategies identified 82 relevant studies with 109 independent effect sizes representing a sample of 22,424 students. Five categories of improvement strategies emerged: technology curricula, nontechnology curricula, instructional strategies, manipulatives, and technology tools. All five…

Despite increasing emphasis on preparing more and better teachers and despite the near universal presence of student teaching across teacher education programs (TEPs), numerous questions about what and how student teaching experiences contribute to preservice teachers' development remain unanswered. Indeed, much of the attention focused on student…

The authors reviewed all peer-reviewed studies with participants from preschool to Grade 8 for this meta-analysis of morphological interventions. They identified 22 applicable studies. Instructional effects (Cohen's d) were averaged by linguistic outcome categories (morphological sublexical, non-morphological sublexical, lexical, and supralexical)…

This article systematically reviews research on the achievement outcomes of four types of approaches to improving the reading success of children in the elementary grades: reading curricula, instructional technology, instructional process programs, and combinations of curricula and instructional process. Study inclusion criteria included use of…

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…

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)

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)

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 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)
