| Abstract: | Learning chemistry requires students to relate chemical equations and other symbolic notation both to molecular or atomic events and to macroscopic laboratory observations and data. Traditionally, textbooks have provided symbolic notation with minimal pictures of either microscopic events or macroscopic events leaving the teacher and student to conjure these pictures from words. This paper describes the design of several CD-ROMs with very different strategies and focus for teaching general chemistry with large databases of visual information. Teacher tools for preparation facilitate the planning of more hands-on laboratory experiences and live demonstrations to develop laboratory observation skills. Presentation materials provide animations of abstract microscopic events and concepts to help teachers explain these molecular and atomic events. Students improve observation skills in laboratories with supplemental computer tutorials that mimic the decision making required for laboratory tasks in a virtual laboratory, but students reinforce the experience and learn techniques with practice in a real laboratory. New college textbooks on CD-ROM, that integrate the molecular animations and laboratory experiments with the introduction of new terms and symbolic representations, portend large changes in all textbooks. |
