Overview[ edit ] Definitions of complexity often depend on the concept of a confidential " system " — a set of parts or elements that have relationships among them differentiated from relationships with other elements outside the relational regime.
Russell Gersten and David J. Chard Abstract We describe the concept of number sense, an analog as important to mathematics learning as phonemic awareness has been to the reading research field.
Understanding the concept of number sense and relevant research from cognitive science can help the research community pull together fragmented pieces of earlier knowledge to yield a much richer, more subtle, and more effective means of improving instructional practice.
More than three decades have passed since Kirk and Bateman proposed that auditory processing was one of the psycholinguistic process deficits underlying specific learning disabilities.
Although subsequent psychometric studies identified the flaws in their conceptualization, our current understanding of the importance of phonological processing and its contribution to reading development suggests that Kirk and Bateman were at least partly accurate in their analysis.
In fact, the most notable advances in the learning disabilities field since the late 's have been in reading disabilities, a subtype of learning disabilities. More specifically, important advances have been realized in the prevention e. These advances are primarily the result of the growing knowledge base on phonemic awareness and its importance to the development of strong reading skills.
We believe that there may be an analog as important to mathematics learning as phonemic awareness has been to the development of reading. Our goal in this article is to introduce this analog.
To accomplish our goal, we briefly review the concept of phonemic awareness and its crucial role in helping students with learning disabilities to learn to read. Then, we demonstrate how this concept helps the research community pull together fragmented pieces of earlier knowledge and yield a much richer, more subtle, and more effective means for improving instructional practice than earlier conceptions e.
Furthermore, we describe what we view as important findings concerning children's acquisition of mathematical concepts, by developing the idea of number sense. We demonstrate how the number sense concept can inform and significantly enhance the quality of mathematics interventions for students with learning disabilities, just as the concept of phonemic awareness has informed the field of reading.
The number sense concept acts as a lens to reveal reasons for relative successes and failures of past attempts at innovations. In particular, we review the research of Hasselbring, Goin, and Bransford and Pellegrino and Goldman from a contemporary perspective. We conclude with a model of understanding specific learning disabilities adapted from Kolligian and Sternbergand Geary, We demonstrate how this can he a useful framework for conceptualizing interventions.
Our model indicates how the number sense concept provides a sensible middle ground in what is becoming an increasingly heated controversy about how to teach mathematics.
In our approach, we rely on Cobb's conceptualization of constructivism as a joint approach. In this conceptualization, mathematical learning occurs as students a learn the conventions, language, and logic of a discipline such as mathematics from adults with expertise: We believe that cognitive insights can, and should have a profound impact on how math is taught to special education students and can help radically reform the mundane drill and practice typical of special education mathematics instruction.
In this article, we draw analogies between phonological awareness and number sense. We also draw analogies between earlier research on ways to remediate mathematical disabilities and earlier research on reading disabilities.
The goal here is to provide a brief overview of phonological awareness concepts and number sense before introducing the concept of number sense, rather than to attempt to provide a comprehensive review of either topic.
Overview of phonological awareness In the reading field in the s, based on insights gained from cognitive psychologists such as Perfettithe consensus was largely that fluent, virtually automatic decoding was essential for comprehension. As a consequence, sustained efforts were critical to transform students with learning disabilities into fluent readers.
Typically, there were two components: There was, perhaps, an underlying sense that merely teaching phonics was insufficient for helping students with disabilities to learn to read.
Yet, there were some findings that could not be explained by this view. Kavale for example, found that correlations between auditory skills and reading were consistently positive and consistently replicated. Similarly, Gersten and Carnine noted that, in particular, the skill of auditory blending was highly correlated with reading measures.May 11, · Reading, Writing, Arithmetic, and Lately, Coding Image Imran Khaliq, 12, helped his brother Farhan, 7, left, and Aidan Brown, 6, at a school computer coding event .
