External representations (pictures, diagrams, graphs, concrete models) have always been valuable tools for the science teacher. The formation of personal, internal, representations visualizations from them plays a key role in all learning, especially in that of science. The use of personal computers and sophisticated software has expanded into the areas of simulation, virtual reality, and animation, and students now engage in the creation of models, a key aspect of scientific methodology. Several academic disciplines underlie these developments, yet act independently of each other, to the detriment of an attainment of what is possible. This book brings together the insights of practicing scientists, science education researchers, computer specialists, and cognitive scientists, to produce a coherent overview. It links presentations about the cognitive theory of representation and visualization, its implications for science curriculum design, and for learning and teaching in classrooms and laboratories.

Central roles of representation and visualization in all learning, especially of science Rapid growth of use of computer-based virtual representations in science education Bringing together of insights of scientists, cognitive scientists, science education researchers, computer graphics specialists, science teachers Coverage of cognitive theory and implications for curriculum design Implications for classroom and laboratory learning and teaching
