Communication with class members on a field trip can make the trip real even for those left behind. Demonstrations given in class can be videotaped and made available to students studying the material that evening. Giving Prompt Feedback One of the primary virtues of computers is the support of prompt feedback. Professor and student can stay in touch when either one is out of town. Paper submission deadlines can be assigned for any hour and day.
Materials distributed electronically can be hyperlinks to, for example, the day s weather.
Students can be polled for understanding during a lecture. Grades can be returned to students as soon as the grades are ready, instead of waiting until class meets. A big difference enabled by computers is continuous dialogue. Moreover, because the computer can overcome the necessity of both geographic proximity and simultaneity, lecture notes can be made available anyplace and anywhere, tutors and course advisors can be available at odd study hours, experiments can be repeated outside normal class hours. There are a number of ways computers can be employed in the communication of high expectations.
