The exciting new Sixth Edition expands on the visualization pedagogy from coauthor Stacey Lowery Bretz and makes it even easier to implement in the classroom. Based on her chemistry education research on how students construct and interpret multiple representations, art in the book and media has been revised to be more pedagogically effective and to address student misconceptions. New projected visualization questions help instructors assess students' conceptual understanding in lecture or during exams. A new Interactive Instructor's Guide provides innovative ways to incorporate research-based active learning pedagogy into the classroom.
