The purpose of this resource guide is to identify and describe teaching, training, and staff development materials that meet three basic criteria: they are good, they are readily available, and they are inexpensive. These resources may assist educators, trainers, supervisors, and other personnel preparation decisionmakers in designing quality preservice and inservice experiences. The guide is divided into two sections: materials on instructional content and materials on the instructional process. The instructional content section provides annotated listings of materials with which to enrich preservice and inservice personnel preparation in 14 key early childhood/early intervention content areas. These include: assistive technology, diversity, early care and development, evaluation/assessment, family-professional collaboration, Individualized Family Service Plans/Individualized Education Programs, inclusion, interagency collaboration, legislation, service coordination, specific populations, state planning and resource development, teams, and transitions. The instructional process section describes resources to enrich the design of quality personnel preparation efforts including family participation materials, and personnel preparation and development materials. Each section includes primary and supplemental resources and includes information on the content of the materials, date, medium, and cost. Appendices include a list of sources for the materials, an author index, and a title index. (SG)
