Mosaic consists of eight texts plus two instructor's manuals for in-college or college-bound nonnative English students. Mosaic I is for intermediate to high-intermediate students, while Mosaic II is for high-intermediate to low-advanced students. Within each level, I and II, the books are carefully coordinated by theme, vocabulary, grammar structure, and, where possible, language functions. A chapter in one book corresponds to and reinforces material taught in the same chapter of the other three books at that level for a truly integrated, four-skills approach. Each level, I and II, consists of four books plus an instructor's manual. In addition to .A Reading Skills Book, they include: • A Content-Based Grammar I, II: Each grammar chapter relates to a specific theme, so the exercises focus on contexts and ideas. There is a wide variety of comunicative, functional activities. • A Content-Based Writing Book I, II: These books provide students with short readings on the chapter themes and include many prewriting, revision, and vocabulary-building exercises. The books focus on the writing process, particularly on techniques for gathering ideas, such as "brainstorming" and "freewriting," and on using feedback to rewrite. • A Listening-Speaking Skills Book I, II; These books teach study skills and language functions through active listening activities based on lectures on chapter themes and sample conversations. A variety of speaking activities to reinforce language functions is also included. A cassette program with instructor's key accompanies each text. • Instructor's Manual I, II: These manuals provide instructions and guidelines for use of the books separately or in any combination to form a program. For each of the core books, there is a separate section with teaching tips and other suggestions. The instructor's manuals also include sample tests.
