Describes the function game, or input-output game, and its benefits. One person is the computer and thinks of a rule. Classmates give input values and the computer gives the corresponding output. The object is to guess the rule. Benefits include the use of mental mathematics, problem solving, communication opportunities, and fostering key ideas,…

This study examined the effect of video-based contextualized advisement and competition on transfer of mathematics skills in a computer-based simulation game in which participants helped their "aunt and uncle" fix up a house. Participants were 123 seventh- and eighth-grade students. Results indicated an interaction between competition…

Presented is a mean-value theorem that generalizes the Taylor-Lagrange formula. Discussed is the asymptotic behavior of the remainder term of the formula. Several numerical schemes are derived to approximate the solution to initial-valued first order differential equations. (KR)

Discussed are various models proposed for the Moebius strip. Included are a discussion of a smooth flat model and two smooth flat algebraic models, some results concerning the shortest Moebius strip, the Moebius strip of least elastic energy, and some observations on real-world Moebius strips. (KR)

Describes several ways to implement the NCTM Standards in technically enhanced classrooms. Presents examples from "Computer-Intensive Algebra." Provides suggestions for implementation. (YP)

Appropriate uses for graphics calculators in precalculus and calculus are discussed. The functions of Casio, Sharp, and Hewlett-Packard brand calculators are stressed. A "Stress Test" for graphics calculators designed to illustrate common errors and to furnish examples of tasks which cannot be completed on these instruments is provided.…

Presented are four activities for grades K-eight focusing on the application of mathematics to real-world situations of spending money. The objectives, directions, extensions, and answers for each activity are described. Worksheets are provided. (YP)

Examined are the sex differences in mathematics achievement from a cross-cultural perspective using the data of the Second International Mathematics Study. The overall sex differences in geometry and measurement areas are reported. It was found that differences among countries were greater than sex differences. (YP)

Discusses an experience in presenting tessellations in both classrooms and teacher inservice workshops. Describes preliminary activities, nibble techniques, and tessellation art. Provides 2 worksheets and a glossary of tessellation terms. Lists materials and 27 references. (YP)

Explains a new way of viewing Bayes' formula. Discusses the revision factor and its interpretation. (YP)

Provides an alternative analysis of the reliability associated with the van Hiele Geometry Test based on the assumption that the norm-referenced reliability coefficients provided by the developers were inappropriate. Discusses the agreement coefficient and the kappa coefficient. (YP)

Presents techniques for developing spatial visualization while dealing with concepts of area, proportion, and symmetry. Provides the objectives, directions, extensions, answers, and worksheets for each of the four activities. Describes involving parents. (YP)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)

Describes the use of interactive video material for teaching mathematics using the doomsday system developed in England. The material on the videodisc contains photographs, maps, text, and statistics. Printed materials were developed to help guide the students in the use of the video material. Results of the classroom trials with the materials are…

Describes methods for teaching able students mathematical problems. Provides four problems and discusses the students' responses to them. (YP)
