Because many handicapped students leave high school without a reasonable knowledge of the world of work, a clear understanding of self in relationship to potential occupational pursuits, or a mastery of the basic skills required to function in different occupational roles, the National Center for Research in Vocational Education developed and evaluated a set of instructional materials entitled Math on the Job. Thirty instructional booklets and a teacher's guide were designed for use with mainstreamed mentally retarded, learning disabled, and emotionally disturbed high school students. Drafts of the booklets were pilot tested at four sites. Major revisions were suggested and implemented. Next, eight booklets were field tested with 80 treatment-group and 40 control-group students at the four test sites. Although program students scored higher on the posttest than did the control group students, their gains in knowledge were relatively small. Therefore, the materials were revised extensively and reformatted. (Appendixes to this report include an occupational definitions booklet; lists of occupational tasks, related math skills, and content specifications for 30 occupations; various evaluation forms; the project pre- and posttests; a fact sheet, draft brochure and draft news release describing the booklets; and a marketing plan.)
