The purpose of this project was to revise and reformat 12 instructional units for the professional, pre-service education of potential vocational teachers in Minnesota. These 2-hour units include 30-minute filmed presentations. Developmental activities included the trial use of these units on 60 potential teachers in four separate classes.
