This document describes a project which was designed (1) to develop a program to teach concepts to young children, and (2) to pilot test the program using college students as teachers of Appalachian children. The instructional program was composed of a series of visual discrimination problems in which the child must discriminate the correct from the incorrect example of the concept. An errorless discrimination procedure was combined with positive reinforcement. A preliminary evaluation of the effectiveness of the teaching method and materials was made to determine the feasibility of organizing college students as preschool volunteer tutors. It was concluded that (1) college students were highly motivated and creative teachers, (2) tutors, children, and parents enjoyed participating in the program, and (3) exploratory data indicated that the programs, teaching methods, and evaluation procedures provided a good framework for the teaching program. Appendices include information and materials associated with the learning program, data forms, student evaluation forms, lists of supplementary activities compiled by the tutors, and newspaper articles and communications relevant to the project.
