Describes an activity in which students graph changes in tides and ocean levels over a period in order to obtain a visual representation of the changes taking place and their effects upon the Earth. Provides questions for students to answer after construction of the graphs. (RT)

Gives definitions of taxicab geometry and the MacDraw format for graphing. In the world of taxicab geometry, movement through the plane is along horizontal and vertical paths. Describes specific application to conic sections, including circle, ellipse, parabola, and hyperbola. Lists five references. (YP)

Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)

Describes the different effects for four types of activities on students' pronunciation of targeted second-language (L2) vocabulary used in oral presentations. Samples of pronunciation were elicited at three points. The observed effects over time are presented graphically, and the complex learning processes underlying these effects are discussed.…

Recounts a college economics professor's attempts to explain macroeconomic concepts to a blind student. Considers how explanations of economics principles often rely on graphic presentations. Describes experimental tactile adaptation, using graphs made out of sandpaper, yarn, spaghetti, and other materials. Recommends developing prefabricated…

Describes an exercise for college and high school students that relates descriptive statistics to the regional climatic classification. The exercise introduces students to simple calculations of central tendency and dispersion, the construction and interpretation of scatterplots, and the definition of climatic regions. Forces students to engage…

Statistical literacy is defined as "the ability to read and interpret data: the ability to use statistics as evidence in arguments. Statistical literacy is a competency: the ability to think critically about statistics" (Schield, p. 2). When a definition of statistical literacy is considered it can be seen that all students can manage a…

Methods that have been employed in McGill University's (Montreal, Quebec) program of research into the nature of learning are described. The methods illustrate four phases of inquiry: conceptualization or model-building; data gathering techniques; data representation; and data analysis. For the university's learning task project, the development…

A procedure for developing a nomogram that depicts expectancy of success on a criterion from performance on two predictors is presented. Data from 574 medical students attending Michigan State University College of Human Medicine's classes of 1979 through 1984 were used to develop a model for predicting the expectancy of success on Part I of the…

The program is designed to provide a system for joining job seekers and job providers in Community School District No. 9 through a medium of teaching and training and to meet the immediate and future job training needs of community residents. The program was conducted according to the following processes: (1) a needs assessment, an income and…

Argues that first-year algebra should be taught in eighth grade. Outlines an algebra course that could provide average students with a working kowledge of algebra. Proposes that this would require students to have experiences with variables, equations, formulas, and graphs during previous years of study. (TW)

Explores graph theory and use of topological indices to predict boiling points. Lists three indices: Wiener Number, Randic Branching Index and Molecular Connectivity, and Molecular Identification numbers. Warns of inadequacies with stereochemistry. (ML)

Details the 1989 funding proposals for research and development. Describes trends in federal spending. Discusses proportions of funding for the National Science Foundation, the Department of Defense, and other basic research agencies. Includes tables that detail money spent and proposed for many research agencies. (CW)

Both on-line and face-to-face courses rely on textbooks as an important source of information for students. A challenge for instructors in an on-line setting is to insure that students are learning from their textbooks. One way to address this challenge is to use productivity software tools to develop assignments that promote student thinking and…

Presents a small group activity that helps elementary students explore volume as part of the math curriculum. Collecting data through hands-on experimentation; analyzing the data; and using graphs and graphing software to further understanding are discussed. (LRW)
