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.
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.
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 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.

Key difference: Java is a programming language, which has been influenced by the C language.
It derives much of its syntax from C and C++, however it has fewer low-level facilities than either. Java is a general-purpose programming language that is designed to have fewer implementation dependencies as compared to previous languages.
Implicit memory is one of the two main types of long-term human ashio-midori.com is acquired and used unconsciously, and can affect thoughts and behaviours. One of its most common forms is procedural memory, which helps people performing certain tasks without conscious awareness of these previous experiences..
Implicit memory's counterpart is known as explicit memory or declarative memory. In answering this question one must define procedural and declarative memory.
Befriending () defines procedural memory that contains procedural knowledge. Procedural knowledge is the how to do things skills and recall Is without conscious.

Declarative memory can be further sub-divided into episodic memory and semantic memory. Procedural memory (“knowing how”) is the unconscious memory of skills and how to do things, particularly the use of objects or movements of the body, such .
