Chapter 5. Computer-Based Interactive Video

• Interactivity as a feature of instruction is shared by many traditional media and instructional methods. The also interact with a book as they study it, marking passages, jumping around to reread a section, correlation text with diagrams and pictures. P105
• Although videotapes to some extent permit interruptions and replays of linear sequences, the attraction of videodiscs is that they combine the representational qualities of video with the interactivity afforded by computer program control. P105
• It is not clear to what extent video contributes to any increment in effectiveness of interactive video over computer-based instruction that is not video based (e.g. studies such as Dalton, 1986) P108
• Interactivity between the learner and computer can be characterized in several ways. It can be characterized in terms of the kind of cognitive processing produced by the ways learners receive information, the elicitation of overt responses, the ways in which learner responses are analyzed and the kind of actions that are taken in responding to and guiding the learner. (Jonassen, 1988). P108
• Although achievement comparisons favour interactive video over linear cideo, instances where the same video material is made interactive by adding extra features such as questions, feedback, and branching indicate that learning time may also be extended. P109
• Discussions of repurposing existing video into the interactive video format provide a contrast between the characteristics of linear video and the way it must be configured for interactive video. P110
