Scientific practice involves the construction, validation and application of scientific models, so science instruction should be designed to engage students in making and using models. This pdf article discusses the benefits of using model construction and development in an Interactive Engagement learning framework. The methodologies and ideas discussed in this article have been incorporated in physics and teacher training courses. The article can be found in E. Redish & J. Rigden (Eds.)
