In this paper, the teaching-learning strategies adopted by Open
Universities and Correspondence Course Institutes in our country have been reviewed. The various technologies being used by them are identified and relevant parameters developed and models relevant for delivery of programmes by Open Universities and CCls are reviewed. Keeping in view the requirements of the models discussed, and types of technology used, relevant performance indicators have been developed for script and production, curriculum and instructional design, feed back, interactivity, learning effectiveness, access etc. The quality assurance mechanism relevant for the above parameters are also indicated.
