Provides a framework for observing and supporting the development of students as constructivist teachers, especially during their field placements as student teachers. The instructional shift to a constructivist approach is described, and guiding principles and possible indicators of the constructivist model are presented. (SLD)

Explorer is an interactive environment based on a constructivist epistemology of learning that integrates animated computer models with analytic capabilities for learning science. The system includes graphs, a spreadsheet, scripting, and interactive tools. Two examples involving the dynamics of colliding objects and electric circuits illustrate…

Reviews the history of the concept of equal educational opportunity, noting the shift from a separate-but-equal input definition to an opportunity-to-learn process interpretation. Also discussed are implications of the definition of opportunity to learn for professional development and the education of African-American students. (SLD)

This article critiques the "Research, Development, and Dissemination" model for development of innovations in special education and urges greater recognition of the cultural perspective for understanding resistance to change by teachers. Difficulties teachers have had in implementing Direct Instruction principles and their reactions to…

Attempts to distinguish between the lecture method and the constructivist approach, in general, and by citing classroom scenarios. The author cautions those whose writing seems to unintentionally endorse traditional lecture and drill and practice methods. (MKR)
