Guidelines for teaching English as a second language (ESL) are directed at teachers and teacher trainees. With an emphasis on teaching ESL quickly and efficiently to adults, the six chapters address teaching ESL to competencies, teaching ESL to nonliterate adults, vocational ESL, ESL instruction in the workplace, teaching ESL in the multilevel classroom, and coordinating and training volunteer tutors. Teaching methods, program designs, objectives, materials, and testing are among the topics considered. Each chapter includes suggested resources and reading. The appendix provides an outline of generic concerns and specific models for adult ESL. The six models presented are ESL for survival, literacy, basic skills, general vocational, occupation-specific, and home management. (RW)
