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)

Ecological case study data were used to determine high school pupils' and university students' ability to organize and use these data to predict outcomes of interaction between populations within a community. The poor quality of answers given by the respondents suggests that explicit teaching, prior to the use of the case study, may greatly…

Presents activities using the theme of collecting and interpreting data from the students' own classroom. Stresses communication among students and between students and the teacher. Includes reproducible student worksheets. (MKR)

Reports on research that examined the clustering of similar books provided by a classification system and ways in which the books that patrons circulate are clustered in a university library. Measures of classification system performance are suggested and used to evaluate two test collections. Consequences for full-text document systems and online…

University students (n=158) were examined to determine whether first describing a mathematical relationship by a written English sentence would affect success in constructing an algebraic equation. Students using common idiomatic forms of English that could not be directly translated into mathematical notation were found to be the most successful.…

Because assessment instruments of the future may well be composed of a combination of types of questions, a way to combine those scores effectively is discussed. Two new graphic tools are presented that show that it may not be practical to equalize the reliability of different components. (SLD)

Ignorance of the characteristics of a mixed population may lead to bias in a summary measure of a phenomenon. A test based on sample kurtosis is demonstrated by a simulation study to be more powerful than six other known tests in detecting a class of mixed normal distributions. (SLD)

Reports findings of a 1988 study on intellectual freedom in media centers in Wisconsin. General status information and factors influencing challenge outcomes are discussed. Data on materials selection policy, media specialist characteristics, complaints, and roles of those involved in challenges are presented. The appendix describes the…

Discusses activities to help students make visual generalizations about power and exponential functions, methods to determine an approximate function represented by data using logarithms, hands-on activities, and student activity sheets. Includes a Pascal Turbo computer program which generates random numbers. (MKR)

Argues that teachers and lecturers need to identify essential skills which are technology-independent and need to determine the most effective use of new technology in the classroom. Examines prospects for change using the newer technology of graphing calculators for mathematics courses. Contains 15 references. (ASK)

Presents the ALEXIA system, a lexical-learning environment for French as a second or foreign language, and describes its network module, which can automatically build graphs of certain lexical semantic relations. (Author/VWL)

Describes a physics laboratory exercise that focuses on an idea common to all scientific disciplines; that is, there are scaling laws that relate one measurable physical variable to another. (WRM)

Discusses key areas in science that require students to have a well-developed sense of numeracy for full understanding. Suggests that some of the difficulties students have with numeracy arise from not distinguishing between the teaching of facts and skills and teaching through conceptual understanding. Makes some recommendations for correcting…

Explains how the graphing calculator can be used in simulations of physics experiments and how its use for plotting graphs requires a shift in emphasis from obtaining an experimental result to evaluating that result. (DDR)

Presents a historical perspective of French immersion training programs in Canada. This overview shows that after a period of uncertainty, faculties of education are well prepared to provide immersion teachers with preservice and inservice education. The article maintains that teaching in immersion is in continuous evolution, and practicing…
