This guide describes activities used by language teachers in developing students' oral communication skills. Activities are presented for instruction in English as a Second Language as well as other second languages. Ideas are organized in 4 parts, with 14 subsections: fluency (conversation, fluency and interaction, group work, dialogues and role plays, games for speaking, using audiovisual aids); accuracy (functions, grammar, vocabulary); pronunciation (segmental phonemes, suprasegmental phonemes); and speaking in specific contexts (oral presentations, spoken English for academic purposes, interviews and questioning). Each idea is described briefly, with information given about appropriate proficiency level(s), specific aims, class time requirements, preparation time, needed resources, procedures, and caveats and options.
