This guide for elementary teachers who are not trained in techniques of English as a second language (ESL) but who have limited English-speaking students in their classes offers specific classroom techniques for helping those students. The first section presents a brief summary of research in first and second language acquisition. The second and third sections outline selected ESL principles and present specific techniques for teaching ESL with examples and suggestions for classroom use. The techniques and other second language teaching concerns include Total Physical Response, Silent Period, verbal interaction, relevancy of lessons, language cumulation, communicative competence, pedagogical sequence, grammar, word lists, translation, use of a bilingual dictionary, and reading and writing. The remaining sections deal with classroom environment; classroom management; teaching strategies; low-stress activities for science and social studies, mathematics, and penmanship; and sources of help beyond the classroom. Grammar and vocabulary excerpts from published texts and a list of guidelines for peer tutors are appended. (MSE)
