The conundrums discussed are: (1) Can media be used for instruction when people feel that its purpose is purely entertainment? (2) How much credibility can there be in messages originating from mistrusted sources? and (3) Is comprehension related to the sophistication of technology used in instructional presentations? Also in this issue: Brajesh Bhatia discusses the evaluation of mass communications in terms of questions to be answered and designs to be used; Ronald Cross describes the University of Mid-America as an example of higher education reaching part time adult learners through educational technology; Selma Dublin reports on a successful use of folk media and radio in Malaysia.
