Videodisc Technology as a Conceptual Research Tool for the Study of Human Theory Making.
Segall, Ricki Goldman
Videodisc technology could have a dramatic effect on the future of educational research by allowing users to access and manipulate the actual raw data in multiple ways. The supposed threat to traditional research methodologies is that there is apparently no systematic way for different viewers to reach the same conclusions about the same content. A possible solution is suggested by the research project, "Learning Constellations," in which "content granularity" is being built into the design of the videodisc and the user interface. Three case studies with elementary school children illustrate the use of content granularity, a way of defining the smallest meaningful unit of content for any section of material on the disc. It is a measure for setting a minimum grain size to ensure that the unit cannot be subdivided. Building a system where each unit is a thick enough description could enable the user to come closer to understanding the underlying intention of the action, event, or process. Thick description is using images, gestures, or sequences that convey meaning. In this way, conclusions, although not the same, will tend to fall into the same range, allowing traditionalists to acknowledge that videodisc technology deepens scientific inquiry about human theory making.
