With the rapid technological changes and the diverse people demands and conditions, traditional educational systems and institutions are forced to provide additional educational opportunities. A number of educational establishments are contributing to these conditions and demands by developing and offering distance education programs. Distance education is a delivery system of teaching and learning, when the teacher and the student are separated by physical distance and time, using alternative media resources when students and instructors have difficulties of establishing face-to-face communication. In distance education, instruction delivery between tutors and students is done using different delivery systems such as computer mediated communication systems, video tapes, printed material, cassettes, instructional television (Berge, 1998). With development of the Internet and the global network system, universities immediately took the advantage of the World Wide Web to deliver the instruction to almost any node in the world, regardless of physical distance and time. The initial questions to be resolved by institutions offering distance education relate to how effective is the program taught by distance learning, and is it a sufficient replacement for traditional face-to-face education. The effectiveness of online instruction is measured by the level of interaction, how well it satisfies the students' needs, and how it eliminates communication barriers between the involved participants. Communication barriers exist in any communication process. They are greater in distance education due to physical distance between members, insufficient technology skills, difficulties using media, need for more human interaction, time constraints and restrictions, and lack of experience with distance education. These problems make it hard to establish the distance education process and develop effective communication between members. The degree of these barriers differs from institution to institution, from one program to another, and for different systems used for delivery. (Contains 31 tables.)
