English Language Learners (ELLs) are one of the fastest growing student populations throughout the country. With ELLs come unique challenges schools must navigate to best serve these students. One challenge is the identification of these students and proper placement and service within ELL programs offered by schools. Another challenge is…

This brief report summarizes research on dyslexia. It is intended to provide an initial look at this common type of learning disability that impacts 1 in 5 students. Included in the brief are links to the original source material and to supplementary resources and videos to learn more.

This study examined primary school teachers' knowledge of anxiety and excessive anxiety symptoms in children. Three hundred and fifteen primary school teachers completed a questionnaire exploring their definitions of anxiety and the indications they associated with excessive anxiety in primary school children. Results showed that teachers had an…

Students with difficulties in specific cognitive processes and academic achievement with otherwise normal levels of intellectual functioning are classified as having a learning disability (LD).

Discusses the definition of dyslexia, reintroduces the concept of marker variables, proposes a strategy for developing an updated marker variable system, presents a preliminary working set of dyslexia marker variables, and calls for eventual adoption of this or similar marker variable systems to facilitate future research efforts. (Author/CR)

It is argued the proposed definition of dyslexia is restricted to developmental dyslexia in which a student struggles to learn to read and does not apply to acquired dyslexia in which a previously normal reader loses reading functions. The need for classification schemes for defining specific learning disabilities is emphasized. (Contains…

Discusses the revised definition of mental retardation in a 1992 manual by the American Association on Mental Retardation.
