Abstract
The Association for Educational Communications and Technology (AECT) officially adopted and approved the following definition of instructional technology: Instructional (educational) is the theory and practice of design, utilization, management and evaluation of processes and resources for learning (Seels & Richey, 1994, p.1). Interestingly, the words technology or technological are never used in this definition. Distance education,which is a very important instructional technology, through open universities has increased in several countries. It includes two-way communication media that allow for direct interactions between teachers and remote students. It conquers restraints imposed on conventional education by time and space, and offers higher quality instructional design.
