The focus is on how line graphs can be used to approximate solutions to rate problems and to suggest equations that offer exact algebraic solutions to the problem. Four problems requiring progressively greater graphing sophistication are presented plus four exercises. (MNS)

Topics for investigation in mathematics classes that arise from the Olympics are discussed. Activities with performance records leading to the development of graphs are illustrated. (MNS)

Describes an approach to generating graphs that represent the relationship between pieces of quantitative information and play upon the reader's perception of those relations. (AEA)

This research applied a cognitive model to identify item features that lead to irrelevant variance on the Test of Spoken English[TM] (TSE[R]). The TSE is an assessment of English oral proficiency and includes an item that elicits a description of a statistical graph. This item type sometimes appears to tap graph-reading skills--an irrelevant…

This paper explores children's efforts to make sense of graphs by analyzing two students' use of a computer-based motion detector. The analysis focuses on the students' growing understanding of the motion detector which enables them to plan their movements in order to create graphs and interpret them in terms of kinesthetic actions. Students…

Understanding students' challenges about using microcomputer based laboratories (MBLs) would provide important data in understanding the appropriateness of using MBLs in high school chemistry laboratories. Identifying students' concerns about this technology will in part help educators identify the obstacles to science learning when using this…

This book suggests creative, classroom-tested mathematics activities to teach number recognition and counting, number formation, sorting and classification, measuring (including time and date), shapes, graphing, estimating, ordinal positions, money, patterning, tallying, and fractions. Activities are presented in the forms of games, crafts, songs,…

This study uses an algorithm-based visual display technique (FACES) to provide enhanced detection of multivariate outliers within large-scale data sets. The FACES computer graphing algorithm (H. Chernoff, 1973) constructs a cartoon-like face, using up to 18 variables for each case. A major advantage of FACES is the ability to store and show the…

The author details graph exercises and solutions, coordinated with a "new textbook," to explain gas laws for isoprocesses, the first law of thermodynamics, and heat transfer. (JH)

The emphasis in these investigations is to analyse the available data in an attempt to find the areas of employment for graduates and to spot the employment trends and attempt to quantify them scientifically. (Author/RK)

As one way of applying and enriching mathematics instruction through integration with science, four mini-projects'' are briefly presented. The three topics are oil molecule estimation, animal classification, graphing and genetic sequences. (MS)
