Peer coaching develops from a leadership role on the part of educators of linguistically and culturally diverse (LCD) students, together with an interdisciplinary cooperation between bilingual/English as a Second Language (ESL) and mainstream staff. Peer coaching is a professional development method in which teachers share their expertise and provide one another with feedback, support, and assistance for refining present skills, learning new skills, or solving classroom-related problems; it can also include in-class training by a supportive peer. Peer coaching is an ongoing process. Benefits include formation of relationships to coordinate the knowledge and skills needed to help LCD students effectively, improvement in teaching, and development of a more positive outlook towards LCD students by mainstream teachers. Peer coaching programs can be initiated by two teachers jointly planning instruction segments or by assigning a more skilled teacher to teach others. Four working models of peer coaching are described in detail: technical, collegial, challenge, and team. Factors to be considered before implementing a coaching system are listed, and coaching program implementation strategy steps are offered. Six specific strategies for low-cost coaching arrangements are suggested. (Contains 23 references.) (NAV)
