The study revealed that learner environment and life-time experience have an important role in the planning and organization of an effective distance learning delivery system. Finally, research suggests that the effectiveness of distance learning is based on preparation, educators' understanding the needs of learners and instructors' understanding of the target population and their instructional needs rather than excessive attention to innovation and the delivery systems. The planning and organizing of instructional materials for distance education have increased the effectiveness of the delivery process. When an instructor spends this much time for researching, planning, and organizing, the instructional process becomes strengthened. Some distance learning instructors usef graphics, video tapes, and printed materials during their lecture to illustrate content area.
Students can now communicate with their instructors by the use of electronic mail and fax.
Mackwood also claimed that computers have become the preferred long-distance communication tool in distance education. Companies such as Microsoft, Corel, and Roger Wagner have revolutionized the software market by including incredible presentation packages with a variety of functions for classroom instruction. Packages such as PowerPoint, Harvard Graphics, and Corel applications are used for creating innovative presentations for classroom instruction. HyperCard and HyperStudio software packages allow the instructor to create their own multimedia projects and presentations which have added another dimension to the instructional process. Finally, the declining cost of computing equipment, more available software applications, and telecommunications tools have allowed student access to college and university campuses for interactive conferences with their instructors.
