In recent years, researchers have shown interest in errors that can frustrate teaching, training, and learning. A discussion of the form an overall theory of error might take is presented in a comparatively discursive and nonrigorous way. Thirty-two references are listed. (Author/CHC)

Provides overview of significant facets of Error Factors (EFs)--promoters of underlying confusion in learning--discussing main types of EFs, sources of EFs in learning contexts, factors influencing frequency of EFs, use of tests and exercises, and effects of EFs and their mistreatment. Forty-seven sources are listed. (EJS)

Describes a microcomputer-based system for diagnosing children's multiplication errors which incorporates the knowledge base of all known systematic multiplication errors, and utilizes a modular approach to cope with the program's complexity. Each module's function, how the programs interact, and the design of pupil-machine interaction are…

Summarizes information processing models of the mind based on a literature review; describes a prototypical model of college learning; examines links between mental models and cognitive errors; reviews cognitive science students; and identifies six factors contributing to cognitive error production. (104 references) (Author/MBR)

Presents five simulation models reflecting sequential levels of children's simple arithmetic story problem solving skills. Outputs of the models are compared with data obtained by presenting 60 five- to eight-year-olds with change problems to examine models' deterministic nature. Results indicate the models give an adequate description of behavior…
