| Abstract: | Video recorders, microcomputers and viewdata systems each have a unique contribution to make to education and training. In combining these three developments, however, the possibility emerges of using video as the basis of an integrated study medium. Such a medium could interpose videotext with videoprogram, provide explanation or ask questions, enable adaptive structuring and present knowledge in many different ways. In particular, it could provide the opportunity for interaction during each individual's study encounter. This paper expands on these possibilities and illustrates their relationship using a media paradigm constructed from the dimensions of image change‐rate and response‐demand. |
