Introduction

Title Computer Aided Learning (CAL): What are the issues? Done By Sharif Sharif A. Presentation of the Issue The applications of computers are growing rapidly, and expectations of this technology are growing at the same rate. One of the newest branches of computer application is Computer Aided Learning or CAL. Although computers and educational packages are generally in use today, Computer Aided Learning in the future will be even more essential and important. Today computers are used as a big, fast encyclopedia or data book, a tape recorder, type writer or video, but in the future CAL systems will contain smart adaptive trainers that will adapt themselves to learners' features and propose the best method of teaching. Again, we will have more remote learning and video conferencing instead of today's traditional classes. CAL now is a new idea, but as time goes by, it will become very important and wide-spread. B. The IT Background of the Issue In this part we shall look at the various types of CALL and where they might be employed in a typical lesson, turn to look at the major types of CALL software and how they might best be used in the class. Most class lessons in language learning follow a pattern on the lines of: 1. ...read more.

D. Solution to the Problems Arising from the Issue During the 70's, CAL systems were developed but the development rate was still low, because of some technical and also economical limitations, especially concerning hardware that was still expensive, massive and mainly without adequate sound and graphic facilities. ...read more.
