This book contains revised and updated versions of paperspresented at a NATO Advanced Research Workshop held inMilton Keynes, U. K. , in summer 1990. The workshop broughttogether about 30 world leaders in the use of advancedtechnologies in the teaching of mathematics and science. The papers demonstrate how technology is impacting the viewin the teaching profession of what should be taught, whatcan be taught, and how teachers should go about their workin the various disciplines. They offer great insight intothe central issues of teaching and learning in a wide rangeof disciplines and across many grade levels, ranging fromelementary school through college and undergraduateeducation. The book has two major parts, on advanced technologies inthe teaching of science and mathematics respectively,although many of the papers address topics of interest tospecialists in both areas. The papers reflect examples drawnfrom a wide range of fields, including mathematics, physics,computer science, engineering, chemistry, and biology. Somedemonstrate the use of software inteaching difficult butrestricted concepts within a discipline. Other show anintegrated approach that exploits the power of educationalsoftware throughout a course. The notions of discovery,representation, qualitative models for reasoning, modelbuilding, and the management of complexity are key elementsin numerous papers.
