The final report describes a project to facilitate the efficiency with which legally blind persons use their remaining vision. The project developed a diagnostic assessment procedure, a design for instruction which includes 150 sequenced lessons, and a sourcebook on low vision. The reliability and validity of the diagnostic assessment procedure were evaluated with 112 legally blind students. Reliability and content validity were found to be high, but some questions existed about the test's construct validity. The entire program was field tested by 11 teachers of legally blind students who responded to questionnaires on the kit's effectiveness and on each specific component. A number of problems in the materials were identified and corrected, resulting in the final version, Program to Develop Efficiency in Visual Functioning. (CL)
