This document describes the construction/simulation software called Stella which can be used in the investigation of dynamic causal models. Topics considered are its built-in perspective of system dynamics and capabilities, its potential drawbacks, and its cognitive implications for educational applications. (JJK)

Explains a proposed block of instruction that would give students in industrial engineering, operations research, systems engineering, and applied mathematics the basic understanding required to begin more advanced courses in simulation theory or applications. (DDR)

Characterizes algebra as a way of reasoning involving variables/functional relationships, generalization/modes of representation, and mathematical investigation/argument. Examines curricular goals; considers contributions of technology to reconceptualize algebra; and suggests directions for future development of tools and models, research agendas,…

Results of a study involving 94 preservice elementary teachers suggest the instruction students in such programs should be given to develop computer literacy. A model for computer education which consists of four stages is presented in detail. It is recommended that all preservice elementary teachers go through the first two. (MP)

Examples of subroutines that generate both symbolic and graphic solutions to differential equations are presented for the two computer algebra systems, MAPLE and Mathematica. Included are the listings for the Mathematica procedures developed for use in this article. (JJK)

Explains the integrated approach implemented by James Madison University, Virginia, in enhancing computer literacy. Reviews the changes in the mathematics courses and provides topical listings and outlines of the courses that emphasize computer applications. (ML)

Describes a compulsory computer education course for pre-service elementary and secondary teachers at the University of Calgary, Canada. Reviews the course content, laboratory topics, and provides an evaluative overview of the program's first year of implementation. (ML)

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)

Describes the approach used in a doctoral seminar on designing instructional software for problem solving in mathematics. Explains how a five stage software development model was followed for producing materials. Includes student evaluations of the course. (ML)

CLIMB (Center for Learning and Instruction in Mathematics-concept Building), a model of prescriptive and instructional modes supporting practical approaches to meeting needs of adult learning, is based on premises related to learner needs, implications of mathematics education research, and relevant education for the future. These premises and…

Describes the deterministic simulation (a given input always leads to the same output) and probabilistic simulation (new states are subject to predefined laws of chance). Provides examples of the application of the two simulations with mathematical expressions and PASCAL program. Lists seven references. (YP)

Suggests that intuition and visualization are effective methods of introducing engineering principles to pre-engineering students. Describes the development of computer simulation software as part of a "Pre-Engineering College On Disk" course. The computer game helps students visualize the relationship between shell trajectory and its…
