Mathematical skills are becoming increasingly critical for achieving academic and professional success. Developmental dyscalculia (DD) is a childhood-onset disorder characterized by the presence of abnormalities in the acquisition of arithmetic skills affecting approximately 5% of school age children. Diagnosing students with possible dyscalculia…

Background: Perception disorders are frequently observed in persons with intellectual disability (ID) and their influence on cognition has been discussed. The objective of this study is to clarify the mechanisms behind these alterations by analysing the visual event related potentials early component, the N1 wave, which is related to perception…

Teenagers with nonverbal learning disabilities (NLD) have difficulty with fine-motor coordination, which may relate to the novelty of the task or the lack of "self-talk" to mediate action. In this study, we required two teenagers with NLD and two control group teenagers to touch the thumb of each hand firmly and accurately to the fingertips of the…

The author presents a task analysis model for interpreting diagnostic test performance and for planning a remedial program for learning disabled students. A survey of evaluation instruments is given for eight skill areas, including oral expression, listening comprehension, and basic reading skills. A case study illustrates the approach. (CL)

For the purpose of developing a diagnostic and prescriptive program for children with learning problems in mathematics, task analysis is employed to develop a hierarchy of skills which identifies a terminal task and prerequisite skills. (Author/DB)

Discussed are characteristics of criterion referenced reading tests for use with learning disabled (LD) children, and analyzed are the Basic Educational Skills Inventory (BESI), the Prescriptive Reading Inventory (PRI), and the Cooper-McGuire Diagnostic Work-Analysis Test (CooperMcGuire). Criterion referenced tests are defined; and problems in…

This paper examines the effectiveness of the Project MECCA (Make Every Child Capable of Achieving) model for early identification and mainstreaming of children with potential specific learning disabilities (SLD). The MECCA model incorporates collaboration between the learning disabilities teacher and the classroom teacher within the classroom…
