This report presents the field tests plan including site selection for the Basic Skill Development Through Vocational Education Project. (The project's purpose is to develop Resource and Teacher Guides to provide vocational and occupational education teachers with information about ways of incorporating basic skills instruction into occupational education and about resources to help facilitate implementation of a coordinated and integrated basic skills program within a vocational program.) Chapter 1 provides assumptions underlying elements of the field test plan. Chapter 2 reviews development, evaluation, and revision activities which led up to the field test. Chapter 3 is the recommended field test plan itself. Topics covered include purpose, materials, evaluation criteria (usability, effectiveness, generalizability), groups involved in field testing, data collection instruments, field test activities (site selection, site preparation, materials usage, site close-out), data analysis, and timetable. Five appendixes include (1) materials evaluation criteria, topics, and questions; (2) descriptions of data collection documents; (3) relationship between the documents and evaluation questions; (4) field test sites; and (5) draft versions of data collection instruments. The fifth appendix comprises approximately 75% of the report. (YLB)
