Describes several exemplars of software that emulate and incorporate machine-supported aspects of cognitive apprenticeships in science and mathematics. Concludes with an evaluation of software against cognitively guided principles and with a summary of the difficulties associated with creating and implementing machine-supported apprenticeships.…

The implementation of the first phase of a project involving the use of computer software in a course on the mathematics of finance is discussed. Results of a controlled experiment indicated that the techniques employed seemed to have positively impacted the performance of the students. (CW)

A nonconventional graphical way to represent functions (the Parallel Axes Representation) is discussed. A computerized environment designed to support the exploration of the representation of linear functions is described. The didactical potential of this representation is illustrated. (CW)

The results of a simulation model of a queuing system are reported. Use in an introductory quantitative analysis course to enhance students' computer and quantitative modeling knowledge is described. (CW)

An experimental class in introductory statistics (n=40) using simulation software at American University was compared to a traditionally taught control group (n=36) with respect to achievement and accrued beliefs about the benefits of the simulations. Results indicate significantly higher achievement scores for the experimental class with about…

Examines the interaction between mode of computer assisted instruction and cognitive style on the understanding of concept relationships and mastery of factual information. Finds learners are more effective when matched to the appropriate mode of computer assisted instruction. (MVL)

Describes the application of expert systems to provide computer-assisted instruction support to students to facilitate their learning of both fundamental and advanced statistical concepts. Provides examples of both a modular system and an integrated system which utilize VP-Expert, an expert system development shell. (14 references) (Author)

Presented are several simple kinetic systems together with the spreadsheets used to solve them. A set of exercises in chemical kinetics appropriate for an introductory course in physical chemistry is given. Error propagation calculations with experimental data are illustrated. (CW)

Presented in this paper is a model of a preservice teachers' course on the use of computers for science and technology instruction. The main goal of the course is to lead the students to realize the potential offered by the medium for instructional purposes and to develop self-confidence. (Author/KR)

Described is a weekly computer algebra laboratory course for Calculus I students during the 10-week spring semester, 1990, at Trinity University. Advice on the establishment and management of this type of laboratory including descriptions of student participation trends and student reactions is presented. (JJK)

Evaluates present conditions and recognizes current methodology being used for rule-based systems and schema-based systems, and gives examples of these systems. Lists educational implications of artificial intelligence and expert systems. (MVL)

Described is the V-scope which is a Micro-Based Laboratory system that provides direct and immediate displays of real motion as spatial images (stroboscopic snapshots), as time graphs of any combination of position, velocity, and acceleration, or as vector diagrams of velocity and acceleration. Illustrations of system components and of typical…
