In this section you have studied the use of media devises involving audio and video presentations. Although the use of audio and video programming in education has a long history, including radio and television for educational purposes, the media has re-emerged with renewed vigour during the nineties mainly because of the possibility of digitisation. The use and potential of audio and video programmes as a standalone leaning environment, as well as the potential for incorporating learner interaction and integration with other experiences are discussed in a number of case studies. The section also examines interactive radio instruction (IRI) and interactive audio instruction (IAI) as extended versions of radio and video with enhanced learning effectiveness. Similarly, Internet protocol television (IPTV) and videoconferencing are also discussed as extension of analogue and digital television and video. On the whole this section aims to provide the reader with a fairly concise yet comprehensive idea about the use and potential of audio and video media and also their extended versions with enhanced learning effectiveness and applicability.
