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. (Contains references.) (Author/CR)

Describes the successful use of a computer algebra system (CAS) with a student as he worked on a problem involving functions far more difficult than he had previously encountered. (Author/NB)

Described is a procedure for studying the trajectories of projectiles using ball bearings and aluminum foil. Trajectories were measured with and without the effects of air resistance. Multiflash photography was used to determine the flight paths of all objects. (KR)

Summarizes the issues covered in the 1988 literature on nonbook processing. The areas discussed include cataloging of computer files, music and sound recordings, film and video, graphic materials and three dimensional objects, cartographic materials, and preservation of nonbook materials. A bibliography of 80 sources is provided. (CLB)

Discusses the use of graphing calculators for polar and parametric equations. Presents eight lines of the program for the graph of a parametric equation and 11 lines of the program for a graph of a polar equation. Illustrates the application of the programs for planetary motion and free-fall motion. (YP)

Describes four laboratory activities in algebra and precalculus classes that provide hands-on experiences related to functions: slowing down the acceleration of gravity; calculating the acceleration of gravity; generating a parabola using a steel ball and a tilted board; and photographing projectile motion. (YP)

Discusses a graphical analysis method used in the physics laboratory. Shown are various kinds of graphs to illustrate the relationship between two variables. A procedure for deriving equations from laboratory data is described. (YP)

Presented is an activity in which a mystery setting is used to motivate students to construct their own decay curves of melting ice used as an analogy to radioactive decay. Procedures, materials, apparatus, discussion topics, presentation, and thermodynamics are discussed. (CW)

Provides examples of such statistical graphs as line, bar, picture and pie. Suggests uses of Logo Turtle Graphics in graph construction. Includes several program procedures for creating designs with the computer. (RT)

Contends that, although most economics students are acquainted with the graphical analysis of the income and substitution effects of a price change, they often fail to appreciate that the same graphs provide information on the income elasticities of the two goods. Illustrates the proof of this concept using mathematical formulae and five graphic…

Asserts that, despite changes resulting from new theories on international trade, simple graphs in the Heckscher-Ohlin-Samuelson tradition remain a significant part of most courses in international economics. Provides four figures illustrating these economic concepts. (CFR)
