Book Details
A text and media package that helps students develop their molecular-visualization skills as a key part of becoming expert problem solvers.
The Fifth Edition's new coauthor Stacey Lowery Bretz, uses visualization tools-based on Chemistry Education Research and focused on the particulate nature of matter-to help students self assess what they know before, during, and after each chapter. Smartwork5 allows instructors to use this pedagogy as a diagnostic, and students receive hints and answer-specific feedback within the system. New ChemTour animations further support visualization at a molecular level and are integrated throughout the media package.
