Presented is an activity that may be used to help students clarify the basics of graphing while allowing individuals to collect data and perform a simple experiment. A timetable, rules for graphing, materials, procedures, and suggestions for extension activities are provided. (CW)

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)

Evaluates the educational potential of the Domesday Interactive Videodisc System, which contains a massive data collection about many aspects of Great Britain and British life. Reviews the technology of the Domesday System and describes its functionality. Two case studies detail how the Domesday System may be used in teaching British geography.…

Outlines differences between classical statistics and exploratory data analysis. Provides examples in the use of the exploratory techniques. (YP)

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Computer software with graphic representations of functions can teach algebraic concepts, or can blur or obscure concepts of great importance. Making good use and bad use of visual imagery are each discussed. Then a general theory of interpretation of graphs is proposed, and a list of examples is presented. (MNS)

Presents the case for the maintenance of Cantonese and Modern Standard Chinese in Australia. The article examines the numerical strength of the speakers, cultural dissimilarity between the dominant and minority groups, concentration of minority groups at focal points, interaction patterns of the minority group and change in Australian language…

Use of probes and data-logging software to introduce dynamic line graphs to young children in the context of science investigations found this approach facilitated effective use of line graphs as models of relationships between variables. (Author/MKR)

Discusses techniques for improving training program design and administration through effective evaluation. Describes three sample case studies that compare trainers, facility/location, and course content; trainee reactions are plotted on a graph. Presents trainee feedback forms that identify aspects of a session, rate effectiveness, and record…

Describes the use of the TI-82 graphics calculator as an intermediate step in introducing computers to the high-school physics lab. Discusses linking the calculator with other machines so that students can save data, enter programs on a computer and later download to the calculator, and transfer graphs to a computer for printing. (JRH)

Discusses obstacles to making recycled office paper cheaper. Explains how the economics of recycled office paper discourages recycling by commodity mills. Includes discussion of integrated and nonintegrated mills, commodity and specialty mills, specialty printing and writing mills, postconsumer material, supply and demand, and economic…

Suggests a classroom activity for teaching psychology students about group norms. Calls upon students to conduct peer surveys about a particular behavior and then to represent approval or disapproval of the behavior graphically. Argues that the activity increases student understanding of survey research methods, the need for controlled research,…

Discussed is a method of approximating the roots of a quadratic that allows the discovery of relationships between parabolas and circles and between the use of geometry and algebra. Included are the procedure and justification of the method. (KR)

Described is a computer software package suitable for teaching and research in the area of multicomponent vapor-liquid equilibrium. This program, which has a complete database, can accomplish phase-equilibrium calculations using various models and graph the results. (KR)

The article addresses the needs of primary grade teachers, focusing on whole language. It offers strategies from various primary teachers on such issues as classroom supplies, whole-language displays, literature-based activities, charts, graphs, language logs, end-of-the-day journals, and a class tooth book.
