Prior research and development demonstrates that dynamic notations and multiply-linked representations can enable ordinary students to achieve extraordinary learning of scientific and mathematical concepts (Kaput, 1992). However, prior techniques for building such software have resulted in expensive, incompatible, and inflexible products (Roschelle & Kaput,(More)
One of the main questions raised in the Foundations for the Future Conference was: What conceptual systems provide powerful foundations for success in mathematics or science classes? The chief goal of this chapter is to outline a conceptual framework— called DNR-based instruction 2 (or DNR, for short)—claiming to be such a system. DNR-based instruction(More)
