The book, designed for teachers of both beginning-level and transitional students of English as a Second Language (ESL), outlines the Guided Language Experience Process (GLEP) model for planning ESL instructional units using the whole language approach. The first section summarizes research that has influenced this model and its implications for teachers. The second section describes the empty model for unit planning and offers instructions on how to use it, including a generic unit plan. A GLEP unit consists of two basic parts: (1) an idea page that outlines the unit theme, focusing and motivational aspects, closure and evaluation plan, concepts, vocabulary, skills (both English language arts and mathematics, science, and social studies content), and resources and materials; and (2) unit planning pages, which further break down the whole into component parts (specific focusing and motivation strategies, input, guided oral practice, reading/writing activities, extended activities for integration, closure and evaluation activities). A series of sample units on comparative folklore, common threads in human experience in different cultures, and pond life are then provided. The final chapter offers more detailed discussion of strategies and terms. A glossary, sample daily lesson plans, list of resources and useful topics, and bibliography are appended. (MSE)
