Discussed are several activities suitable for students from middle school through high school designed to furnish concrete experiences with the concepts of rate of change and slope and approximating areas, the central themes of differential and integral calculus. The implementation of national curriculum standards is stressed. (CW)

Lists a BASIC program which computes the equilibrium constant as a function of temperature. Suggests use by undergraduates taking a one-year calculus-based physical chemistry course. Notes the program provides for up to four species, typically two reactants and two products. (MVL)

Studies of word problem solving of story problems are reviewed and six immature strategies commonly used by elementary and junior high school students are highlighted. Suggested are some recommendations for mathematics instruction. (YP)

Explored are responses of students aged 9 to 13 to linear generalizing problems from both a technical and strategic point of view. The methods commonly used were the same in all age groups and across all three questions, although some students choosing each model varied. (YP)

Describes teaching strategies that help students improve problem solving skills. Lists three factors good problem solvers were found to possess. Gives step by step instructions for solving problems. (MVL)

Implements a table algorithm on a spreadsheet program and obtains functions for several number sequences such as the Fibonacci and Catalan numbers. Considers other applications of the table algorithm to integers represented in various number bases. (YP)

Describes how three dimensional LOGO was used in a workshop session for secondary pupils and mathematics teachers. Provides many commands and output drawings. (YP)

Describes examples of force in daily living. Discusses some examples of gravitational, internal, external, and centrifugal forces in various situations by using force vectors with diagrams. (YP)

Discusses a new method for determining the eigenvalues of the Schroedinger equation when the potential energy function does not have a simple form. Describes the mathematical methods and provides an application. Lists limitations to the method. (MVL)

States that the relationship between mathematics and physics in the first year college level might be similar for populations from different national and cultural backgrounds. Reports student responses in two schools on topics covered by a mathematics test. The similarities and differences between the two groups are discussed. (YP)

Reviews some important properties of the bimolecular reaction between the hydroxyl radical and carbon monoxide. Investigates the kinetics of the reaction, the temperature and pressure dependence of the rate constant, the state-to-state dynamics of the reaction, and the reverse reaction. (MVL)

Gives definitions of taxicab geometry and the MacDraw format for graphing. In the world of taxicab geometry, movement through the plane is along horizontal and vertical paths. Describes specific application to conic sections, including circle, ellipse, parabola, and hyperbola. Lists five references. (YP)

Abstracts six conference papers from the ISRAEL Association for Computers in Education. Included topics are spreadsheets for problem solving, concept acquisition with microcomputers, numerical mathematics, learning math as a science, studying polygons with LOGO, and a growth curve simulation of microorganisms. (MVL)

Investigates the probability of winning the largest prize at Bingo through a series of five simpler problems. Investigations are conducted with the aid of either BASIC computer programs, spreadsheets, or a computer algebra system such as Mathematica. Provides sample data tables to illustrate findings. (MDH)

Presents the following activities for teaching elementary students about the metric system: Metric Soda Fountain, Metric Meals, Metric Moola, and Metric Golf. (PR)
