Drawing from her extensive experience of using cases in teacher education and in-service courses, Katherine Merseth offers this practical, hands-on guide to improving the teaching of mathematics. This book, the first to focus on the secondary school classroom (grades 7-12), provides a collection of cases that blend important mathematics content with the real complexities of school and class-room life. "Windows on Teaching Math: - Responds to the ongoing efforts of the National Council of Teachers of Mathematics (NCTM) to change both the content and practice of teaching mathematics.- Provides pre-case discussion exercises that help keep the discussion focused on the mathematics presented in the case.- Focuses on topics that are often difficult to teach and challenging for students to learn, such as proportional reasoning, probability, and independence.- Presents actual student responses that exhibit the misunderstandings and ambiguities of thinking, offering a window into the mathematical reasoning of students.- Confronts often unaddressed influences on teaching such as, relationships with colleagues, disgruntled parents, tracking, diverse student populations, instances of cheating, and much more.
