The third volume of the 24th annual conference of the International Group for the Psychology of Mathematics Education contains full research report papers. Papers include: (1) "Mathematics classrooms functioning as communities of inquiry: Possibilities and constraints for changing practice" (Susie Groves, Brian Doig, and Laurance Splitter); (2)…

This monograph is a guide to effective presentation of report data and information from institutional research. The work focuses on several types of presentation: the written report (alternative ways for presenting information, appearance, and the audience); graphic displays or charts (to present words or data in an organized or symbolic fashion;…

Designed for use by General Educational Development (GED) program teachers in GED classrooms, this set of learning materials provide learners with practice in graph and chart reading, calculation, analyzing information, and writing, while they examine the labor market, role of higher education, and economic impact of the GED. Unit 1, The Labor…

This research discusses the relationship between the migration of skilled professional and managerial workers from Canada to the United States, the so called "brain drain," and seeks to determine if and how the Canada-U.S. Free Trade Agreement (F.T.A.) and the North American Free Trade Agreement (NAFTA) may have affected bilateral flows…

Tested whether a relationship existed between the method of presentation of statistical data and (1) reader retention, (2) reader reaction, and (3) reading time. Found that reader retention was highest for reports with tables; reader reaction was most favorable for reports with graphs; and reading time was shortest for reports with tables. (PD)

Provides a brief overview of single-subject research designs. This method exercises its power by examining changes in single subjects' responses over time across experimental conditions. Describes a classroom project in which students collect repeated measures of their own behavior and graph the data. (MJP)

Describes chemistry software that is part of a balanced educational program. Provides several applications including graphs of various relationships among the elements. Includes a brief historical treatment of the periodic table and compares the traditional historical approach with perspectives gained by manipulating an electronic database. (DDR)

Reconsiders Uriel Spiegel's analysis of the Giffen phenomenon, a utility function that yields an inferior good with an upward-sloping demand curve. Extends this to include similar utility functions that yield inferiority. Discusses the earlier work of related theorists including Liebhafsky, Vandermeulen, and Wold and Jureen. (MJP)

Reexamines Spiegel's analysis of the Giffen phenomenon, a utility function that yields an inferior good with an upward-sloping demand curve and incorporates Christian Weber's criticism into the model. Disagrees with Weber on some points but agrees that as income decreases the likelihood of the Giffen product decreases. (MJP)

The Triple Representation Model of problem solving is presented. The use of microcomputers in this problem-solving environment is discussed, and examples are provided. The integration of this method into the mathematics curriculum is described. (CW)

Discusses the use of computers in calculus classes. Describes activities in four laboratories providing with the problems of the laboratories. (YP)

Shows how census data illustrated in pie charts, bar graphs, line graphs, and a map can be used in teaching students to read and interpret large amounts of information about the community, state, and country. Provides examples from "An Advance Look at the 1990 Census" (World Eagle) and suggests activities and discussion questions. (LS)

Discusses the use of the computer to encourage a versatile approach to learning involving both symbolic/logical and visual/holistic types of mental activity. Provides experimental data showing the effect of an enhanced Socratic mode of teaching. (YP)

Describes how the tapping of maple trees can be used to teach lessons in science on boiling points, density, solubility, and other sugaring projects in the curricula. Outlines activities and precautions to follow when doing this project. (RT)
