Case studies were developed and analyzed during the spring and summer of 1991 for 10 workers participating in workplace classroom training. These adults were nominated by their respective labor unions because they provided good illustrations of how workplace educational programs can affect literacy and job performance. Descriptive methods used to collect and record data were interviews, a background questionnaire, and a daily log sheet of job activities for 2 consecutive days. Students translated these log sheets into job/task analysis records and indicated the extent to which job tasks were affected by the literacy courses taken. All students noted improvement in oral, written, and reading skills, which enhanced their own self-esteem and allowed for greater opportunities on the job and in their everyday life. Those workers who took technical courses noted progressive development in technical abilities. Job performance improved whether the course was relevant to all aspects of their work or not. Students became more future-oriented and articulated personal and family goals. Parents influenced their children to develop ambitions beyond high school. (Following the summary of results are the case studies, making up the bulk of the document. They contain illustrations to support the effectiveness of the courses and positive impact of classroom training on the work environment and world outside the workplace. The utility of work logs is also addressed.) (YLB)
