Ellin Oliver Keene and Susan Zimmermann have returned with a new edition of Mosaic of Thought that features 70 percent new material. When the first edition published ten years ago, Mosaic of Thought became a runaway best seller as the first book to explicitly describe the use and benefits of strategy-based comprehension instruction. Since then comprehension strategy instruction has exploded, leading to numerous inspiring variations on Mosaic's instructional principles, as well as a widening of the comprehension research base. Now the second edition offers up-to-the-minute insight for classroom teachers, literacy coaches, and school leaders everywhere, and reminds everyone of precisely what effective, long-lasting comprehension teaching looks like.
