The Role of Anchored Instruction in the Design of a Hypermedia Science Museum Exhibit.
Bell, Benjamin; And Others
A hypermedia simulation, Sickle Cell Counselor, has been developed to anchor instruction for museum visitors using the task of advising couples about the decision to have children when there is a substantial genetic risk of sickle cell disease. A visitor can perform simulated laboratory tests and ask questions via interactive video. The anchored instruction model is closely related to cognitive apprenticeship theory. Patterns of interaction between the user, simulating the role of a genetic counselor, and the program are illustrated through an annotated example. The genetic counseling role makes the Sickle Cell Counselor a compelling program, but the human interest facet is really just a motivational device. The program supports the acquisition of the target knowledge well. The user is supported with knowledge from an experts screen, from learner-initiated coaching, and from implicit task guidance. An evaluation with adults at a community church (21 pretests and 10 posttests) suggests substantial gains in knowledge about sickle cell disease, as well as confidence in the material learned. Ten figures present evaluation findings. (Contains 10 references.) (SLD)
