ABSTRACT
In babies, the visual system lays the foundation for objects and concepts that can later be described in words. The visual system provides an approximate sense of large quantities and an exact count of small quantities. Mathematics instruction should include exercises for developing these spatial skills. Training and experience increase situation awareness, as illustrated by the training of novice drivers and the evaluation of electronic warfare technicians. By the year 2000, almost 90% of universities with more than 10,000 students offered some form of distance learning. The National Science Board makes a number of specific recommendations, one of which is to take advantage of the opportunities offered by new communication technologies. Advance technologies under development by US businesses, universities, and government could create rich and compelling learning opportunities that meet all learners' needs, and provide education and training when and where they are needed, while boosting the productivity of learning and lowering its costs.
