Instructional computer systems for higher education

In most universities, increased instructional utilization of computers by many departments has been the rule. With the associated diversity of instructional requirements and evolving hardware capabilities, the choice of a proper computer system for this environment has been made more difficult. In this paper, a review of the requirements for such a system is presented and the alternatives are analyzed in light of these requirements. It is shown that non-interactive systems are the least desirable educationally and furthermore, that the economic justification for their use is no longer as strong as in the past. In support of this, a description of an inexpensive interactive system currently in use at Harvard is given.
