Abstract
The purpose of the study was to evaluate an experimental prescriptive teaching programme and its effectiveness in enhancing reading, arithmetic and linguistic developmental skills of institutionalised children in a large state training center for the mentally retarded. Thirty-five children participated in ihe experimental prescriptive teaching project. The educational procedure was a prescriptive, precision teaching approach using positive reinforcement. Teaching emphasised three curriculum areas: reading, mathematical computations and linguistic development. A teacher and teacher’s aide were primarily responsible for teaching the child in the classroom setting. The classroom teacher provided technical assistance and a teaching model. Analysis of the data yielded significant gains (P<.01) in reading, mathematical concepts and linguistic developmental skills.
