Discusses the limitations of crossnational comparisons of secondary student performance in the U.S. and selected European and Pacific industrial countries, using mathematics and science data from the International Assessment for the Evaluation of Educational Achievement (IEA). Suggests the most serious problem is the rise of a new educational…

An approach to teaching multiplication and division with negative numbers that focuses on graphs to illustrate concepts is revealed. The material and problems used are presented with comments on the teaching methods applied with 11-year-olds. (MP)

Some aspects of a study designed to illustrate relations between the size of units and their teaching, research and service outputs, or the structure of their resources are presented. Resources and outputs were measured by total expenditure, hours of teaching, publications, citations, etc. Size was defined by expenditure on staff. (Author/MLW)

Asserts that legal mandates increase the probability that postsecondary instructors will have blind and visually impaired students in their classrooms. The graphical and symbolic notations used in economics courses present special problems for these students. Recommends and describes the usage of tactile graphs and raised line drawings. (MJP)

Discusses some of the challenges faced by blind and visually impaired students, and some of the tools available to help these students in their efforts to learn mathematics. Argues that much of the language of mathematics relies heavily on visual reference. (DDR)

Describes the results of a teacher's exploration of the effects of using graphing calculators in calculus instruction in sections other than those that are experimental. Two experimental and two traditional sections of Calculus I and II participated in the study. (DDR)

Described is an activity in which students calculate constant velocity using a tape cassette player. The objectives, procedures, graphing directions, and formulas and values needed for the calculations are included. (KR)

Described is an activity that uses discarded evergreen trees from Christmas. Tree age and growth characteristics are investigated by looking at the number of whorls and rings of the trunks. Extensions and follow-up activities are included. (KR)

Developed is an interdisciplinary unit that deals with global warming and the greenhouse effect. Included are 10 lessons that can be used to supplement existing plans or used as a basis for developing a new unit. Included are modeling, laboratory, graphing, role-playing, and discussion activities. (KR)

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)

Illustrated is the use of computer- or calculator-based graphing to deepen students' understanding about solutions to inequalities. Two examples which use a zoom-in procedure are provided. (YP)

Presents four Physics General Certificate of Secondary Education assessment practicals which can be photocopied for use in instruction. Includes notes for guidance of teachers in determining student skills in management and organization, designing and carrying out experiments to solve problems, draw conclusions, and select suitable apparatus for…

Discussed are assumptions about technology and classroom equipment, teaching methods, getting started, pitfalls, and the role of algebra and calculus. Suggestions are given for implementing the spirit and vision of the standards. (YP)

Illustrated is the problem of solving equations and some different strategies students might employ when using available technology. Gives illustrations for: exact solutions, approximate solutions, and approximate solutions which are graphically generated. (RT)

Describes an activity in which students graph changes in tides and ocean levels over a period in order to obtain a visual representation of the changes taking place and their effects upon the Earth. Provides questions for students to answer after construction of the graphs. (RT)
