Describes a lesson in science in which students conduct an experiment involving quantitative variables. Outlines the scientific method and the use of ratios to solve proportional reasoning problems. (RT)

Illustrates, through text and graphs, that many striking variations are submerged beneath overall figures of poverty rates. The substantial differences in poverty rate according to race and ethnicity are, in large part, the consequences of major differences in family types and work situations. (SLD)

Presents three activities that integrate Civil War studies into mathematics. Activities involve measurement, ratios, and proportions; percents and graphing; and statistics and data analysis. (MKR)

Demonstrates the use of graphing technology to help students develop and interpret three models of jury behavior and explore the potential effect of such actions as changing jury size. MathCAD, an electronic notebook was used. (Contains 10 references.) (MKR)

Presents a model of the economic theory of regulation and recommends its use in undergraduate economics classes. Describes the use of computer-assisted instruction to teach the theory. Maintains that the approach enables students to gain access to graphs and tables that they produce themselves. (CFR)

Evaluates the validity of the test used to place students in the comprehension-based courses offered by the Second Language Institute of the University of Ottawa. The test is described in the context of the target student population and the comprehension-based courses. Different factors of evaluating the concurrent and predictive validity were…

Examines the use of spreadsheets for solving equations by the method of iterations. The combination of the spreadsheets and graphical representation is shown to be appropriate both for teaching and learning the method of iterations and for investigating properties of equations. (Author)

Described is a membrane experiment that provides students with experience in fundamental engineering skills such as mass balances, modeling, and using the computer as a research tool. Included are the experimental design, theory, method of solution, sample calculations, and conclusions. (KR)

Describes a study that investigated the information needs of rural health workers in Hawaii and their current means of information access. Highlights include ranking of information needs, ranked sources of information, hardware ownership, use of electronic sources, use of document delivery services, and perceived barriers to information use.…

Discussion of elementary school mathematics instruction focuses on computer graphing programs to teach subtraction that use pictorial representations as well as graphs. Classroom graphing activities for first graders are described, and evaluations of student progress based on pre- and posttests are discussed. (two references) (LRW)

Correlations between (1) Michigan school districts' expenditures, various supports, and revenues; and (2) each district's educational background, median family income, racial composition, and dropout rate were analyzed. Data used in this study were obtained from the Michigan Department of Education. (SLD)

Describes a study of first-year students at a university in Scotland that was conducted to determine their use of computers at home and in school, their knowledge about information technology, and reasons for not studying computing. Results are compared with two earlier studies to examine gender-related differences over time. (Contains 12…

Two articles focus on helping primary level students grow. One article on the school-home connection describes interactive math homework assignments that involve parents; the other discusses how teachers can help fearful children adjust to school, noting what children fear and offering seven steps to help overly fearful children. (SM)

This article describes a collaboration between a university professor and a sixth-grade teacher who teamed to introduce algebra using a visual approach. The project began with a study of qualitative graphs, moved on to quantitative graphs, then introduced tables of values and finally concentrated on equations. (Contains 12 figures.)

Statistical data can be represented in a number of qualitatively different ways, the choice depending on the following three conditions: the concepts to be investigated; the nature of the data; and the purpose for which they were collected. This paper begins by setting out frameworks that describe the nature of statistical thinking in schools, and…
