The project designed and developed a videodisc package that provides both assessment and related instruction programs for job-related mathematics problem solving, using simulations to provide direct access to vocational situations. The materials are intended to meet the needs of youth and young adults with mild mental handicaps in transition from school to work. The project analyzed current student performance competencies related to the use of mathematics in both generic and specific vocational situations, designed and developed interactive videodisc materials called "Working with Math," and conducted a pilot test. Students were instructed, and student performance was assessed, in the following areas: measuring length, perimeter, area, capacity, weight, temperature, and time; money values and relationships; money earned; and money-related forms. The report's five sections consist of an introduction, descriptions of the design and development, pilot test and dissemination activities, and a list of 11 references. Appendices, which make up the bulk of the document, include: (1) a list of basic and job-related mathematics skills; (2) the scripts used in the assessment portion of the videodisc program; (3) the scripts used in the instruction portion of the videodisc program; and (4) a pilot test rating sheet.
