The paper encourages the establishment of university-based clinics for the diagnosis and remediation of children's learning problems in mathematics and describes the operation of such a clinic at Arizona State University. Mathematics clinics are seen to serve two purposes: helping individual children overcome their special mathematics learning difficulties, and training teacher/specialists in clinical techniques of diagnosis and remediation. Few teacher education institutions are thought to adequately prepare teachers to deal with learning problems in mathematics, though statistics show that up to 35% of elementary school students are underachieving in mathematics. Among the purposes of the Arizona clinic are devising instructional materials appropriate for training teacher/specialists and developing theoretical models and procedures for diagnosis and remediation. The clinic's student clinicians and professional personnel provide diagnosis and implement remedial work for school children clinical operations are integrated with a graduate course which focuses on diagnostic-prescriptive procedures in school mathematics. A chart shows mathematics learning center operations over a 21-week period from preliminary publicity through the final exam. (DB)
