Describes the learning experiences of young children meeting stem-and-leaf plots for the first time. Presents a vignette that offers a real and dynamic example of how young children can learn, use, and evaluate this powerful statistical display. (Author/ASK)

An explanation is given of the uses of graphs for conveying information pictorially. Picture, bar, line, and area graphs are illustrated. Graphing projects for science, social studies, mathematics, economics, and language arts are listed, and teaching tips are suggested. (FG)

Argues that the aggregate good is a powerful pedagogical device in economics. Uses a simple graphical analysis that demonstrates to the student the concept of an aggregate good, that preferences can indeed be collapsed from many goods to two. (DB)

Presents an alternate approach to teaching quadratics by fully integrating the study of quadratic equations and quadratic functions using graphs. Includes reproducible student worksheets. (MKR)

Presents a method for graphically illustrating Le Chatelier's principle, suitable for the general chemistry undergraduate. (CS)

Contends that, although most economics students are acquainted with the graphical analysis of the income and substitution effects of a price change, they often fail to appreciate that the same graphs provide information on the income elasticities of the two goods. Illustrates the proof of this concept using mathematical formulae and five graphic…

Asserts that, despite changes resulting from new theories on international trade, simple graphs in the Heckscher-Ohlin-Samuelson tradition remain a significant part of most courses in international economics. Provides four figures illustrating these economic concepts. (CFR)

Describes the use of glyphs, simple pictures or graphs whose parts represent information about a given subject, in a second-grade classroom. Includes many examples. (MKR)

Ten issues of a monthly social studies resource, each with a different topical focus, are included in this document. The issues focus on: the American family; the environment; the developing world; U.S. and world population; U.S. and world energy; the arms race; employment and housing; world product and trade; social programs in the federal…

Differing treatments of graphs in mathematics and science are discussed. A teaching sequence to develop contrasts between real and ideal data is suggested. (MP)

Gives a multi-lesson project exploring multiplication arrays. Students are given opportunities to model multiplication tables with rectangular arrays, develop and extend ideas about patterns, organize and present visual patterns symbolically in tables, and represent visual patterns graphically. (MKR)

Contends that, despite ongoing criticism, Allen's arc elasticity formula remains entrenched in the microeconomics principles curriculum. Reviews the evolution and continuing scrutiny of the formula. Argues that the use of the geometric mean offers pedagogical advantages over the traditional arithmetic mean approach. (CFR)

Maintains that teachers and textbook graphics follow the same basic pattern in illustrating changes in demand curves when product prices increase. Asserts that the use of computer graphics will enable teachers to be more precise in their graphic presentation of price elasticity. (CFR)

A classroom exercise to help college students of economics conceptualize, create, and learn from graphs is described. The technique is illustrated with an exercise concerning the concept of supply and demand in consumer markets. Classroom time required for the activity is small, and students become adept at manipulating models without anxiety.…

Describes a lesson plan that instructs third graders to use graphs. Explains learning objectives, motivating students, conducting a class activity that includes graph construction, and concluding and evaluating the lesson. Lists materials needed. (GG)
