This issue explains the concept of externalities (benefits or burdens which accrue to society when there is a difference between the private cost or benefit of an action and the social cost or benefit of that action). These external or social costs of individual actions are often referred to as spillover costs. Three brief teaching units follow…

This teaching guide begins with an explanation of the role of money in the economy, focusing on its circulation or exchange. The use of money as a unit of account, a store of value, and a medium of exchange are explained. Three brief teaching units are included. The grade K-2 unit, "Money Counts," provides games and activities which develop the…

Teachers can use these learning activities to teach about the future in elementary and secondary social studies, science, math, language arts, and arts courses. The purpose of the activities is to help students practice creative-thinking skills, investigate problems relevant to their personal futures, experience the concept of change, and evaluate…

Presents five puzzles or problems that may be used for mathematics enrichment. Ideas include magic squares, tests for divisibility, geometry, palindromic numbers, and a jigsaw puzzle. Solutions are included. (PK)

These activities focus on the unifying concept of faster-moving fluids lowering fluid pressure. Students are able to visualize and measure the dynamics of fluid pressure with the hands-on approach of these activities, which helps to develop conceptual understanding. Activities are organized to show many examples of the same concept to reveal…

Presents an integrated math/science activity that shows students the differences among the three types of volcanoes using observation, classification, graphing, sorting, problem solving, measurement, averages, pattern relationships, calculators, computers, and research skills. Includes reproducible student worksheet. Lists 13 teacher resources.…

Describes teaching methods employed in German elementary school classrooms that develop discovery, creativity, and a spirit of cooperation in students learning mathematics. Methods included free choice of learning activities by students and small group cooperative activities. Students' motivation, self-confidence, social and communications skills,…

Demonstrates the use of "Jumping the Broom," a children's book, to integrate mathematics and social studies. Discusses the use of problem solving, finding patterns, and making conjectures by studying the quilt pattern used in the story. (MKR)

This article describes a calculus lesson that illustrates the nature of cycles in simple systems of nonlinear differential equations through the use of the Lotka-Volterra predator-prey model as incorporated in the computer software package, Phaser (version 1.0). (JJK)

Develops the idea of fractals through a laboratory activity that calculates the fractal dimension of ordinary white bread. Extends use of the fractal dimension to compare other complex structures as other breads and sponges. (MDH)

Argues that creativity is the essence of true learning and explores its role in art education. Studies the creative process at work in several artists. Considers David Perkins' work on the creative process, identifying characteristics of a creative environment. Concludes creativity is more akin to problem solving than to spontaneous and mysterious…

Presented is a teacher's guide for a hands-on activity challenging students to develop problem-solving behaviors by exploring the construction of a right-cylinder of maximum volume from an m x n sheet of metal. Reproducible worksheets leading students through the activity are provided. (MDH)

Describes an approach to teaching the scientific method where an outbreak of cholera within the school is simulated. Students act like epidemiologists in an attempt to track down the source of the contamination. (PR)

Discusses a child-centered science project in which first-grade students integrate design drawing, construction, mathematics, and language arts to solve engineering problems related to constructing robots. Describes the construction of the robots, follow-up activities, and educational research that supports this approach to teaching. (10…

Describes activities integrating science and art education in which students examine slides of impressionist paintings or photographs of meteorological phenomena to determine the weather conditions depicted and to make and defend weather predictions. Includes a reproducible worksheet. (MDH)
