It is estimated that in the United States 15% of the general population has a learning disability (Monarez 1992, p. F3). It is possible that many of the ESL students whom we view as poor language learners are struggling because they too have a learning disability. In many countries, learning disabilities are not recognized or, in some cases, they are recognized but not dealt with. This paper is meant to be a basic primer on learning disabilities. It will describe classroom behaviors associated with several common learning problems, the results of research into them and it will offer practical suggestions to classroom teachers for working more profitably with these students.
