The purpose of this article was to systematically review the available research on learner characteristics that influence the treatment effectiveness of early literacy interventions. Meta‐analytic procedures were applied to a total of 30 studies that met the inclusionary and exclusionary criteria. Mean average effect sizes were computed for seven primary learner characteristic categories: (1) rapid naming, (2) alphabetic principle, (3) phonological awareness, (4) problem behavior, (5) memory, (6) IQ, and (7) demographic. The primary learner characteristics that influenced the treatment responsiveness of early literacy interventions were, in order of magnitude, rapid naming, problem behavior, phonological awareness, alphabetic principle, memory, IQ, and demographics. With the exception of the demographic category, the obtained effect sizes for the primary learner characteristics were moderately large. The demographic primary learner characteristic (i.e., disability, ethnicity, grade‐level status) of children was not statistically (p < 0.05) distinct from zero. The findings, limitations, and future research needs are discussed. 相似文献

Abstract. A multiple baseline design was employed to test the effect of manipulative instruction on the perimeter and area problem‐solving performance of middle and high school students who had been diagnosed with LD in the area of mathematics. Modeling, prompting/guided practice, and independent practice in conjunction with manipulative training were employed to teach both perimeter and area problem‐solving skills. Analysis of data revealed that the students rapidly acquired the problem‐solving‐skills, maintained these skills over a two‐month period, and transferred these skills to a paper and pencil problem‐solving format. This research extends previous findings by revealing that use of concrete manipulatives promotes the long‐term maintenance of skills. 相似文献

Collaboration in research activity is now the rule not the exception. It is encouraged by government, funding bodies and research councils. However, the concept of collaboration is difficult to define. It occurs at many different levels, driven by a complex research system-policy dynamic. Three different models of collaboration – inter-personal, team and corporate – are identified, each with their own rationale, structure, benefits and costs. The paper examines the institutional implications of these models. It argues that institutions and individual researchers conceptualise and operationalise research collaboration in different ways. Although vital to institutional mission, collaborative research is rarely mapped by senior managers with any precision. In general, institutional approaches to the management of collaborative research lag behind the policy rhetoric. The paper concludes with an overview of the key dilemmas for institutional strategists and policy makers posed by the shift towards more collaborative approaches to research. 相似文献
