Psychological aspects of information retrieval and learning in hypermedia environments.
Studies problems in learning and retrieving information in hypermedia environments from the perspective of instructional psychology. It is shown that there are 3 basic problems related to three basic component processes: (1) goal attainment, (2) orientation, and (3) knowledge acquisition. Solutions are divided into those that modify the user through specific training programs and those that modify the hypermedia environment through specific design. Suggestions for training each of the 3 basic component processes are given. Then, approaches for modifying the hypermedia environment are presented on the basis of the theory of teaching functions. These are aimed at implementing nonadaptive design measures, adaptability, and adaptivity. It is concluded that the experimental research methodology in psychology may make major contributions to information retrieval and learning in hypermedia environments.
