A classroom activity for teaching vocational English as a Second Language to adults and focusing on development of listening comprehension is described. The exercise is based on the principles for development of workplace skills offered by the Secretary's Commission on Achieving Necessary Skills (SCANS), and addresses specific competencies outlined by that group. The description begins with specification of performance outcomes (active listening, repeating and paraphrasing, use of phrases and intonation in asking for clarification, giving instructions to another, following instructions given by another), communication teaching points (use of imperatives), SCANS competencies targeted, possible classroom configurations (pairs, small groups, whole class), and needed instructional materials. A four-part procedure for presenting and conducting the exercise is then detailed. Sample visual aids consisting of flashcards of workshop tools, pictures of occupations and jobs, and worksheets for an active listening exercise are included.
