Language acquisition theory and classroom applications are discussed, with a focus on the role of speaking and grammar in the early stages of English acquisition in the English-speaking elementary school setting (kindergarten and first grade). Three stages of natural language acquisition are: (1) the comprehension stage (preproduction--characterized by pointing, nodding, naming), (2) the early speech stage (characterized by yes/no responses and listing words), and (3) the speech emergence stage (characterized by phrases and sentences without fluency). Since listening ability is the basis for speaking ability, the natural approach to teaching language starts with comprehension rather than production. Techniques used in the natural approach to language acquisition at Loara Elementary School, Anaheim, California, are described. A useful technique in developing listening comprehension through motor activities is "Total Physical Response." It starts with the imperative (command) (e.g., stand up, sit down) and provides students with ample comprehensible input in a low anxiety situation. The language experience approach, which encourages students to express thoughts and feelings stimulated by an experience, uses concrete manipulatives and sensory channels (e.g., eyes, hands). Ideas for implementing the natural approach are appended. (SW)
