Describes the features of various computer chemistry programs. Utilization of computer graphics, color, digital imaging, and other innovations are discussed in programs including those which aid in the identification of unknowns, predict whether chemical reactions are feasible, and predict the biological activity of xenobiotic compounds. (CS)

Individuals, randomly selected from important but diverse community and school groups, rated the tasks tested and the items used in the Mathematical Tests of the Australian Studies in School Performance. For tasks at the basic numeracy level, disagreement was generally insignificant. (Author/SJL)

Presents a numerical simulation of a simple food chain together with a set of mathematical rules generalizing the model to a food web of any complexity. Discusses some of the model's interesting features and its use by students. (Author/JRH)

Explains that primitive living structures furnish real-world problems that are solvable using mathematics and computer-modeling techniques. (KHR)

Describes the efforts of the Maricopa Mathematics Consortium, in Arizona, to develop a comprehensive mathematics curriculum focusing on application-driven materials at the precalculus level. Reviews the resulting three modules of sample course materials, and discusses three phases of field testing used to assess the modules. Summarizes results…

Investigates students' conceptions and misconceptions relating to the construction of graphs. Qualitative analysis of students' responses identified three main alternative conceptions. Quantitative analyses of the data indicated that overall students did not enter the learning situation as a tabula rasa. Discusses the theoretical and practical…

Discusses the parallels between Klein's position at the forefront of a movement to reform mathematics education and that of the National Council of Teachers of Mathematics' (NCTM) Standards. Draws a picture of Klein as an important historical figure who saw equal importance in studying pure mathematics, applying mathematics, and teaching…

Presents a project used to help students make connections between linear and exponential models and between arithmetic and geometric sequences. (KHR)

Described is a team assignment where groups of students work on stoichiometry problems that apply to the real world. Teams of students act as chemical companies that have orders to fill for a customer. Included are the details of the customer order, student participation, and the evaluation procedure. (KR)

Presents four examples on arithmetic mean and harmonic mean. Provides solution of each of the examples and instructional activities related to the examples. Lists eight references on mathematical problem solving. (YP)

A project in which students can develop their understanding of mathematical concepts through the collaborative writing of word problems is discussed. Worksheets for project requirements and daily requirements are provided. A Thanksgiving project is proposed. The use of a fashion modeling problem in the statistics classroom is described. (CW)

Presented is a lesson in which the patterns that occur within and between sequences of polygonal numbers present an opportunity for students to analyze, represent, and generalize relationships. Materials, objectives, levels, and directions for this activity are discussed. Worksheets to accompany the activities are provided. (CW)

Presents an instructional strategy for teaching how to solve word problems and understand the operations involved. Describes the acquisition method of the part-whole relationships of problem situations. Provides some samples of the instructional strategy used and classroom test results. Lists nine references. (YP)

Described are activities for measuring the human body. The activities include measurements and calculations, calculating volume and density, problems related to body measurement, and using a nomogram. Several charts, illustrations, and a nomogram are provided. (YP)

Described are several programs that enable the user to evaluate derivatives to order n of any elementary function by using the combination of automatic differentiation method and A Programming Language (APL). Programs calculating first- and higher-order derivatives are presented. Selected APL symbols are appended. (YP)
