A Computer for All Students—Revisited

摘要

Ten years ago graphing calculators started a revolution in the teaching and learning of mathematics. In early 1992 we published an article in the Mathematics Teacher describing inexpensive graphing calculators as computers with built-in graphing software (Demana and Waits 1992). These calculators could be viewed as computers available to all students because of their low cost, ease of use, and portability. Our point was that only a few elite would benefit if teachers had to rely exclusively on expensive computer laboratories to deliver computer-enhanced visualization in mathematics teaching and learning.
