Results indicated that these teachers possessed a sound knowledge base for their work which they are willing to modify to enhance their understanding of LD and their efforts to improve the performance of LD students. The survey…

Two analyses are provided to demonstrate that the population of students with learning disabilities is distinct from the population of low-achievers. Reasons for different interpretations of Bob Algozzine and colleagues' research are suggested. Assumptions surrounding the reality of learning disability are explored, as are differing perceptions…

The questionnaire covered four areas: nature and characteristics of learning disabilities, assessment and diagnosis, service delivery and intervention,…
