Methodological Considerations in On-Line Contingent Research and Implications for Learning. Technical Report.
Whittington, Marna C.
Methods for the implementation of on-line contingent research are described in this study. In a contingent experimentation procedure, the content of successive experimental trials is a function of a subject's responses to a previous trial or trials (in contrast to traditional experimentation in which the subject is presented a previously established sequence of trials that is constant for all subjects.) Computer control of the sequencing of stimuli on the basis of the subject's responses permits the adaptation of stimulus presentations to the response history of the learner, facilitating the optimization of learning outcomes. The manner in which contingent research designs enable the researcher to examine learning problems that are analogous to the problems of instructional technology is demonstrated, with particular emphasis placed on the implications of contingent research techniques for task management, psychological measurement, and research design. A systematic analysis of contingent decision algorithms and on-line programs is presented, and the application of these programs is examined and compared with non-contingent research designs with respect to procedure, data collection, and efficiency.
