This technical report attempts to (1) provide information on issues and factors involved in analyzing extended degree costs; (2) provide brief explanation of how cost-related tools have been used in allocation of resources in similar degree programs; (3) indicate the types of information that are needed in making cost analysis of the extended…

Discussion of laboratory experiment simulation in science and engineering education focuses on the need for authoring systems that can be used to create simulations. An editor for a simulator model containing variables and mathematical equations is presented, and screen displays and data analysis are discussed. (LRW)

The concept of variable is central to mathematics teaching and learning in junior and senior high schools. Described is a structured reflexive exercise designed to reexamine the notion of variable and to rediscover its richness and multiplicity of meaning. (PK)

Discusses the loss of precision that normally results in solving equilibrium problems, particularly as presented through the use of quadratic formulas in most introductory college chemistry textbooks. Provides examples of demonstrations. (TW)

College students were asked to write equations using one of two sets of notational systems. Results indicate that the use of more explicit notation did not help problem-solving performance. (Author/PK)

Determines book obsolescence rates for instructional departments within university by analyzing annual library's circulation and relating patterns of library use to curricular programs. Immediacy and intensity of peak usage, use dispersion, and commonality of use were used to develop acquisition priority weighting formula. Twenty-two sources and…

A method of estimating resident staffing needs is evaluated, including discussion of (1) methodological changes needed to estimate needs for service care and assisting attending physicians with private cases; (2) data collection; (3) representative findings; (4) using cost, ease of use, understandability, communicability, and validity as…

Describes three teaching activities for secondary school mathematics classroom: designing a house; guessing the slope function in a calculus course; and solving the six problems of bisymmetric matrices. (YP)

Describes two easily applied mathematical theorems, Budan's rule and Rolle's theorem, that in addition to Descartes's rule of signs and intermediate-value theorem, are useful in chemical equilibrium. Provides examples that illustrate the use of all four theorems. Discusses limitations of the polynomial equation representation of chemical…

Explains a new way of viewing Bayes' formula. Discusses the revision factor and its interpretation. (YP)

Described are the use of spreadsheet programs in chemical engineering calculations using Lotus 1-2-3 macros. Discusses the macro commands, subroutine operations, and solution of partial differential equation. Provides examples of the subroutine programs and spreadsheet solution. (YP)

Explores the parallel axes representation (PAR) of linear functions. Illustrates the influences of slope and intercept values on the representation. Appended are five exercises for making the PAR programs using BASIC language. (YP)

Illustrates how teachers or students can use spreadsheets. Shows the layouts, formulas, and data of two cases: budget manager and data manager. Seven references are listed. (YP)

Discussed is a project promoting "thinking about what students did" in an Israeli high school. Five examples of the project are described with LOGO commands. Several educational ideas are provided. (YP)

Describes making a cardboard frog. Discusses the physics of various motions of the frog. Provides diagrams showing how to make the frog, the motions, and the mechanics formulas. (YP)
