A requirement of Arizona's Migrant Teacher Institutes was the preparation of instructional resource units. Development of these units was a key element in the three-stage recommendations related to individualizing instruction in both reading and oral language. The three stages were: Room Organization--Realistic Learning Centers, Unit Themes and Committee Activities, and Individual Conference and Record Keeping. This book consists of two of these stages: Room Organization--Realistic Learning Centers and Instructional Resource Units. Part I covers: what a learning center is; how to begin learning centers; suggested learning centers in the areas of language, math, science or health, art, music, and audio-media; and how to evaluate learning centers. Prepared by teachers and administrators who attended Migrant Summer Institutes since 1973, the nine resource units are intended for the intermediate grades, 4-8. Each unit consists of: goals, objectives, motivational activities, sub-topics, evaluation, and concluding activities. Unit topics are: Japan; Arizona citrus; Pinal County, Arizona; career education (banking); corn (its history and uses); metrics; Africa; first aid; and weaving, creative stitchery, and spool knitting.
