In this manual, two methods for promoting English as a Second Language (ESL) students' involvement with and understanding of the host culture are presented: (1) visits by guest speakers; and (2) interactive errands executed within the bounds of the school or surrounding community. First, the philosophy underlying the manual is presented in terms of the significance of communicative competence, the importance of students' self-image, the role of classroom instruction, intelligibility, and evaluation. Next, the manual suggests supervised activities to prepare students for the interactive errands within the community. These activities include: (1) exercises to strengthen listening comprehension; (2) instructor explanations of the purpose of the activity and special vocabulary words and social protocols which might be relevant to the situation; and (3) student-teacher dialogue journals for orientation to and ongoing evaluation of activities. After discussing activities to prepare for and follow-up on guest speakers, the manual offers instructions for community interactive errands, including site visits and team quests; "human bingo," which requires students to obtain the signatures of several individuals fitting a number of descriptions; and idiom searches, which require students to ask three native speakers to explain and illustrate the use of an idiom. Suggestions for preparatory and follow-up activities are included. A bibliography and a reading list comprising a total of 38 items are included. (UCM)
