This book was written to help teachers gain a better understanding of children who are failing in school and to provide a systematic process of attacking their learning problems. The text presents workable principles for determining probable causes of learning problems and for selecting suitable, effective remedial activities. Learning problems dealt with include: visual processing problems (sequencing, memory, abstraction, and discrimination); auditory processing (sequencing, memory, abstraction, and discrimination); verbal processing (production and response); kinesthetic processing (perception, coordination, learning, and memory); and abstract processing (integration, nonverbal concepts, and concentration). For each problem area, the book includes symptoms, instructions for personal observation, tests commonly used to verify and substantiate a specific diagnosis, and suggestions for general classroom assistance and individual remediation. (Contains approximately 80 references.) (JDD)
