• Resumen

  • A highly flexible learning tool, referred to as a dynamic reaction figure, is described. Application of these figures can (i) yield the correct chemical equation by simply following a set of menu driven directions; (ii) present the underlying "mechanism" in chemical reactions; and (iii) help to solve quantitative problems in a number of different areas. Use of this tool allows for an integration of what are currently considered to be different concept areas into a common framework. The characteristics of the tool and how it is used in various concept areas are presented. The exposition starts with simple, more concrete, examples and builds toward more abstract levels of chemical understanding. Concept areas for which applications are shown include acid�base and redox reactions, including organic and biochemical examples; predicting the results of potential reactions; and balancing equations. Simple dynamic reaction figures used to complete and balance reactions can have a quantitative and mechanistic layer added. Appropriate application of this tool at the general chemistry level puts in place a framework that students can use and build upon in further study in chemistry, especially organic and biochemistry.
