Several ways of structuring the early trials of a complex concept formation task were compared. Training trials were divided into two segments: (1) an asynchronous segment with one relevant and one irrelevant cue held constant while one relevant and one irrelevant cue varied and (2) a synchronous segment with all cues free to vary. The…

Describes probabilistic document retrieval systems as a sequential learning process, in which the system learns the parameters of probability distributions describing the frequencies of feature occurrences in relevant and nonrelevant documents. Several techniques for estimating the parameters of distributions are described and the results of tests…

The two studies detailed in this paper investigated the effects of adaptive sequencing of examples and adaptive feedback on concept learning using computer-based instruction. In the first study, two groups of undergraduate students progressed through a set of five behavior management concepts presented in the rational set generator framework.…

Reviews current experimental research that deals with various aspects of learner control in computer-based instruction (CBI). Topics discussed include cognitive styles; computer anxiety; levels of field independence; sequencing; feedback; interactive videodiscs; branching in software menus; varying the density of text; and suggestions for future…

Presents experiments on effects of music instruction, teaching practica, feedback from the instructor, and videotaped self-observation on undergraduates' use of complete sequential patterns and components. Focuses on two levels: examination of effects of systematic instructional structures on acquisition of skills and refinement of constructs for…
