Responsiveness to intervention (RTI) is an innovative approach to the identification of learning disabilities (LD). The central assumption is that RTI can differentiate between two explanations for low achievement: poor instruction versus disability. If the child responds poorly to validated instruction, then the assessment eliminates instructional quality as a viable explanation for poor academic growth and instead provides evidence of a disability. For children who do respond nicely, RTI serves a critical prevention function. Most of RTI research has been focused on early reading. In this article, we describe two ongoing programs of research on RTI in the area of mathematics: one on a comprehensive mathematics curriculum at first grade and the other focused on word problems at third grade. For each research program, we describe the sample, explain how students are identified as at risk for mathematics disability, provide an overview of the interventions to which responsiveness is gauged, and describe some results to date. 相似文献

The purpose of this study was to explore the utility of a dynamic assessment (DA) of algebraic learning in predicting third graders' development of mathematics word-problem difficulty. In the fall, 122 third-grade students were assessed on a test of math word-problem skill and DA of algebraic learning. In the spring, they were assessed on word-problem performance. Logistic regression was conducted to contrast two models. One relied exclusively on the fall test of math word-problem skill to predict word-problem difficulty on the spring outcome (less than the 25th percentile). The second model relied on a combination of the fall test of math word-problem skill and the fall DA to predict the same outcome. Holding sensitivity at 87.5%, the universal screener alone resulted in a high proportion of false positives, which was practically reduced when DA was included in the prediction model. Findings are discussed in terms of a two-stage process for screening students within a responsiveness-to-intervention prevention model. 相似文献

The IDEA reauthorization of 2004 highlights the application of responsiveness to intervention (RTI) to both early intervention (EI) service delivery and learning disabilities (LD) identification practices, creating the potential for wide‐scale execution. Implementation of any educational reform necessitates more than simply changing practices: It is important to understand the foundation upon which the reform stands, as well as the questions yet unanswered by research. This review of literature, therefore, emphasizes what is known about RTI as well as what remains to be learned, beginning with foundational concepts—model iterations—and moving to applications—EI and LD identification. Ultimately, the complexities of the RTI construct, with its potential for systemic change, necessitate a partnership between researchers and practitioners to both implement and further investigate RTI on a wide scale. 相似文献

Infant visual and vocal responses to television. 总被引：1，自引：0，他引：1
To provide a first assessment of television influences on infants in the naturalistic setting of the home, visual and vocal behaviors of 72 infants 6 months of age were recorded during 4 days of exposure to various components of broadcast television programs: sound only, picture only, sound plus picture, or a control stimulus of unpatterned sound plus picture. Infants looked longer at the television set during the sound-plus-picture condition than during the picture-only condition, and they looked longer during both of these patterned picture conditions than during both of the other conditions that lacked a patterned picture. Also, infants vocalized more during the picture-only condition than during the sound-only condition. These findings demonstrate that infants attend to the naturalistic presentation of television stimulation and that they respond differentially to the visual and auditory components of television. The results are discussed in terms of the question of the long-term influence on infants' social responsiveness of substantial levels of exposure to the noncontingent, quasi-social stimulation provided by television. 相似文献

Reflection on subjectivity in the qualitative research process is fundamental to the methodology. Although much attention is paid to what to do (identify subjectivities), there is much less emphasis on how one should do this. Furthermore, a researcher engaged in an intimately familiar setting, such as a typical American classroom, faces the unique challenge of sifting through vast stores of prior knowledge and beliefs that influence perceptions of observed instruction, including experiences as a K-12 learner and classroom teacher. As a novice qualitative researcher and former special educator drawn to questions involving instructional practice in reading comprehension, I struggled to balance my emotional responses to observed instruction with my need to understand teachers' decision-making. I begin by sharing my own experiences as a novice researcher, brought forward from artefacts of that time. Moving to the present, I reflect on my early misperceptions, and conclude with recommendations for working with subjectivity in the research process. 相似文献
