The "Nucleus Course in Japanese," based on the Institute of Modern Languages'"Situational Reinforcement" approach, is designed for 80 to 100 hours of instruction. Each lesson has several sections--Response drills, Appropriate Response Sequence, and Reading. Most of the lessons also include optional sections with Sentences for Repetition or a Structure Note. The text is accompanied by tapes and a tapebook, which may also be used alone as a workbook for homework assignments. All material in these two volumes appears in both Romanci and Japanese characters. (See ED 024 935 for a description of the Situational Reinforcement rationale.) (AMM)
