This document is a comprehensive, annotated series of resource lists designed to assist in selecting resources for the senior high English as a Second Language (ESL) program. This source book is divided into five levels. Level 1 is intended for students who are acquiring literacy for the first time or who have had significant gaps in previous schooling. Level 2 is intended for students who have little or no experience with English. Level 3 is intended for students who have some competency in English and need a program focused specifically on language development for academic learning. Level 4 is intended for students who are able to succeed in most high school courses with consistent support in English language development for academic learning. Level 5 students receive assistance with subject-specific language development in a variety of ways, such as in learning centers, from peer coaching, and with teacher assistance. A comprehensive listing of materials for each level is provided. Cited resources come in audiocassette, videocassette, and printed forms. Prices listed are current as of August 1998; up-to-date price information is available via a provided telephone number. A list of suppliers throughout Canada is included, as is a subject/title index.
