A set of programs, designed to supplement a high school or college course in trigonometry, is described. Student exploration is stressed. (MP)

Three models to predict future world records for footraces are reviewed. The records for the mile run are presented with time and year given in linear, hyperbolic, and experiential relationships. (MP)

A course that incorporates a computer program as a tool to take a more detailed look at differential equations is described. (MP)

Compares the "New York Times" and the "Asahi Shimbun" in terms of density, variety, and extensive use of statistical and didactic graphics. Concludes that cultural factors account for the style of newspaper graphics, social factors for their acceptability, and organizational factors for their type and density. (JMF)

The importance of being able to read and draw conclusions from condensed numerical data is discussed. Four activities, most appropriate for primary students, are suggested. (MK)

Most learning centers for science are custom-made by enthusiastic teachers eager to experiment with a new way to make science come alive for students. Suggests a way to plan a science center for the classroom. (Author/RK)

Presents an interdisciplinary unit in which students ask questions about themselves, gather data, and participate in statistical analysis and graphing activities related to the data. Contains an assessment instrument and data sheet example. (DDR)

Claims that writing systems that constitute a species of graphic systems, such as pictures and charts, are distinctive in that they bear a direct relation to speech. Argues that writing serves as a model for various properties of speech including sentences, words, and phonemes. Concludes that literacy contributes to conceptual structure of…

Argues that children need to be given regular opportunities to gather, organize, display, and interpret their own data. They should have regular opportunities to pose their own questions and represent the results in their own way. Offers five sample survey questions children can pose to each other and examples of data representation by children.…

Describes a classroom activity designed to give students hands-on experience using technology and geometric visualization, as well as to explore fractal geometry in a cooperative classroom environment. Natural phenomena is the context of these activities. Enriches understanding of Euclidean geometry and infinite sequences. Lists materials,…

Describes the study of a physics teacher whose teaching changed as his beliefs about mathematics changed. Following a week-long institute on using graphing calculators, the teacher became an advocate of calculator use and his algebraic thinking progressed as he realized the importance of functions. (DDR)

Presents a five-step method to develop the critical numeracy knowledge of numerically intimidated students. Examines the method in detail, discussing Piagetian diagnostic tools and how to adapt the Structure of the Observed Learning Outcome (SOLO) taxonomy to teach critical numeracy. (CMK)

Introduces a collection of mathematics activities that use Spain and Spanish culture as the setting for activities that involve graphing, estimation, logical reasoning, geometry, measurement, and computation. These activities are designed to appeal directly to students. (KHR)

This study reports results of student graphing of writing after brief free writing periods in the 4th grade. An examination of writing samples over time from students with the highest and lowest writing rates showed improved writing quality in terms of more concrete details and more sophisticated organization.
