An introductory unit on slope, designed to give students a chance to discover some of the basic relationships between functions and slopes, is described. Programs written in BASIC for PET microcomputers were used. It is felt that students have the background to understand derivatives after experiences with this unit. (MP)

The activity described helps students develop facility in working with two-dimensional coordinate systems. Many students find the activity fascinating, so it can be used to motivate students to become involved in a number of explorations and to engender positive attitudes toward mathematics. (MP)

Activities designed to: (1) provide experience in determining the likelihood of events and systematically recording the results of a succession of events; and (2) provide experiences in reading and drawing logical conclusions from graphed data are presented. Worksheet masters designed for duplication for classroom use are included. (MP)

A mathematical system based on six functions is illustrated. (MP)

The use of graph paper to outline arrays of multidigit multiplication problems is promoted. (MP)

How the use of calculators can illuminate mathematics and improve the level of problem-solving discussion in classes is presented. (MP)

The use of graphing skills in the science classroom is described, including prerequisite knowledge, bar graphs and histograms, line graphs, and interpreting line graphs. Graphing skills are utilized as a reinforcement for process skills activities such as data collection and data interpretation. (DS)

The use of graph paper is traced from its origins in research reports in the early 19th century to massive use in the early 1900s. Reflected in this report is the impact of "squared paper" on instructional practices and courses in technical, scientific, and mathematical areas. (MP)

Practical tips on the teaching of subtraction, addition and subtraction of fractions, and finding the vertex of a parabola are given. (MK)

Bar graph activities appropriate for four stages of development are given. (MK)

Some students and all instructional faculty at the U.S. Air Force Academy Library were surveyed by a team of computer and behavioral scientists and library administrators. Findings included a high opinion rating of known services but also identified numerous little-known services and resources; measurable differences in usage patterns were…

A monthly guide to help teach the basic subjects. Here are suggestions for teaching language arts, science and mathematics. (RK)

The ability to listen attentively and critically is crucial. Describes two techniques for improving listening skills. (Editor/RK)

Concrete materials lead young students to abstract conclusions. (Editor)

Reports on a case study of a 16-year-old student working on transformations of functions in a computer-based, multirepresentational environment. Presents an analysis of the work during the transition from the use of visualization and analysis of discrete points to the use of algebraic symbolism. (AIM)
