The paper offers a model for the design and evaluation of computer-assisted instructional programs. Components of a diagnostic prescriptive instructional model are delineated, along with use considerations. A sample software program is evaluated according to criteria for the diagnostic function, the prescriptive function, and user considerations.…

Describes an automatic exercise-problem selection method which is based on the theory of Learning Diagnosis and Treatment (LDT). An optimum problem for each learner is identified by comparing the required readiness for the problem and the learner's mastery level. (Author/CMV)

This paper provides an in-depth view of computer based tutoring/coaching systems and (1) the philosophy behind them, (2) the kinds of diagnostic modeling strategies required to infer a student's shortcomings from observing his behavior, and (3) the range of explicit tutorial strategies needed for directing the tutor to say the right thing at the…

This article describes an approach to modifying science students' alternative conceptions of physical phenomena by means of diagnostic and remedial microcomputer programs designed in accord with a model of conceptual change. Current applications of microcomputers are discussed, including numerical work, drill and testing, tutorials, simulation,…

The theoretical rationales and procedures of five adaptive computer-based instruction models were reviewed: the mathematical model, the regression model, the Bayesian probabilistic model, the testing and branching model, and artificially intelligent instructional systems. Each model is assessed for contrast of methods and forms, identifiable…

Automated Student Modelling explicates reasoning strategies, the representation of procedural skills, and underlying misconceptions as manifested in errors. A diagnostic model, based on a "procedural network" as opposed to a "semantic network," is presented which provides a technique both for modelling the underlying cognitive processes of a…

A classification scheme for multimedia interaction is described based on the degree of control and type of cognitive engagement experienced by learners in prescriptive, democratic, and cybernetic independent learning environments. Reactive, proactive, and mutual levels of interaction and their associated functions and transactions are discussed.…

This study evaluated an instructional model entitled "Integrating Computer Software into the Functional Mathematics Curriculum: A Diagnostic Approach," which was intended to prepare middle-school special education students for the Maryland Functional Mathematics Test. The model consisted of eight major components: pretests/posttests, diagnostic…

Presents a model of instructional design which links cognitive learning theory and instructional prescriptions. Topics discussed include knowledge types and knowledge acquisition; memory system components; learning time; learning objectives, including skills, cognitive strategies, and creative processes; instructional methods that relate to…

This paper reports on the development of an error-coding instrument and a computerized continuous feedback system for the diagnostic evaluation and remedial treatment of unstructured second-language performances and the use of such a system in an instructional setting. The system does the following: it allows quick, objective, accurate, and…

With a speech-language pathologist as consultant, volunteers provided language/concept enrichment to 22 kindergarten students who had low screening scores in the areas of articulation, language, and concepts. Microcomputer software programs were used to teach quantity, quality, time/sequence, nouns, and verbs. Teachers felt that 41 percent of the…
