Research on disproportionate representation in special education has potential to influence policy in ways that rectify educational inequities. In this study, we investigated how disproportionality researchers have operationalized dis-ability, identified key themes and theories used in disproportionality research, and evaluated the coherence…

In education research, small samples are common because of financial limitations, logistical challenges, or exploratory studies. With small samples, statistical principles on which researchers rely do not hold, leading to trust issues with model estimates and possible replication issues when scaling up. Researchers are generally aware of such…

Missing data are a common occurrence in survey-based research studies in education, and the way missing values are handled can significantly affect the results of analyses based on such data. Despite known problems with performance of some missing data handling methods, such as mean imputation, many researchers in education continue to use those…

Despite increased focus on the effects of organized activities on youth development, there is currently no consensus about the best way to assess various dimensions of involvement. This article explores the complexities of assessing involvement and focuses specifically on the following organized activity dimensions: (a) breadth, (b) intensity, (c)…

Evidenced in several now classic reviews of the field, much has been made of theoretical and methodological "difference" with regard to research in the sociology of education. Although such renditions often constitute important intellectual contributions, the authors suggest that it is increasingly important to read across theoretical and…

Most theories of instruction rely on a model of the learner's internal processing system. In this article, three general models of the internal processing system involved in learning to solve problems will be outlined, and will be related to both external instructional procedures and learning outcome variables. (Author/DEP)

Animated models explicate the procedure to solve a problem, as well as the rationale behind this procedure. For abstract cognitive processes, animations might be beneficial, especially when a supportive pedagogical agent provides explanations. This article argues that animated models can be an effective instructional method, provided that they are…

Early work by Bartlett in memory theory is contrasted with the more firmly entrenched empirical-associationistic notions of his time. Contemporary lines of research are then discussed within the perspective of this ongoing controversy. A more purely constructive model with active processing during retention, recall, and comprehension is presented.…

The claim that knowledge alone accounts for variance of memory and development (MAD) is critiqued. Topics include the movement toward a knowledge-based view of MAD and problems with this approach; data suggesting that domain-independent strategies influence MAD; and evidence for a domain-independent tool of developmental import. (SLD)

Reviews the literature regarding desegregation planning and implementation programs. Also discusses the literature regarding the supposed differences educationally between low and middle income children and the quality of education these groups receive. (DEP)

The results of a meta-analysis that found that rewards do not threaten intrinsic motivation have not been well accepted by those who argue rewards produce negative effects under a wide range of conditions. Nevertheless, the results and conclusions of the meta-analysis are held to be valid. (SLD)

Two views of clinical problem solving (CPS) are compared. When research on teachers' cognitions was initiated in 1974, the concept of CPS was invoked primarily in terms of diagnosing and treating dysfunction. Presently, educators have reached a different, hierarchical view. This shift brings teaching closer to art and farther from science. (SLD)

The conclusion of J. Cameron and W. D. Pierce that rewards do not pose a threat to intrinsic motivation (1994) is a misrepresentation of the literature based on a flawed meta-analysis. Their analysis is more an attempt to defend behaviorist turf rather than meaningful consideration of relevant data and issues. (Author/SLD)

This article finds the empirical review of the intellectual effects of family factors by Lala Carr Steelman wanting because (1) it is selective and incomplete; (2) it ignores systematic aggregate effects; (3) it imposes linear analysis on nonmonotone relationships; and (4) it disregards most of the confounds identified by Steelman as crucial.…

The author responds to criticism by R. B. Zajonc on a review of the extant literature on the intellectual consequences of sibship size and birth order. (Author/LMO)
