Topics from graph theory are introduced at an informal level and thereby made accessible to the majority of secondary school students. Three worksheets are included. (MNS)

Investigates the use of mathematical representations in 3 grade-8 general science classes (n=65) that engaged in a 10-week open inquiry about the correlations between biological and physical variables in the environment. Demonstrates the use of representations as conscription devices, and illustrates how the use and understanding of inscriptions…

Explores the development of 280 students across 7 grades in spelling and word knowledge as well as their pattern of use of lower- to higher-order strategies in their attempts to spell words, write derivations, and display syntactic knowledge. Older students gradually make less use of lower-order strategies in spelling, writing derivations, and in…

Discusses reorganizing classrooms for more active participation of students, to give children the freedom to work with mathematical materials in new ways and to allow teachers to monitor children's learning in new ways. Discusses the use of graphing activities to assess children's knowledge. (MKR)

Presents an activity in which students draw a picture, analyze each line and curve, and write the symbolic equations represented by the graph. Includes reproducible student worksheets. (MKR)

Presents five lessons to demonstrate how graphing calculators can be used to teach the slope-intercept concept of linear equations and to establish more general principles about two-dimensional graphs. Contains a reproducible student quiz. (MKR)

Discusses the use of technology to investigate what graphs represent as well as how to interpret graphs. (MKR)

Presents algebraic and geometric solutions with surprising twists to a word problem involving linear functions and postal rates. (MKR)

Provides activities that introduce the sine and cosine functions in a hands-on manner. Includes ideas for assessment. Contains reproducible student worksheets. (MKR)

Presents four examples of physics problems that can be solved with a graphing calculator. Problems included deal with motion, harmonic oscillations, sound waves, and blackbody radiation. (JRH)

This article identifies principles of the constant time delay procedure for teaching skills to students with disabilities and details a graphing method for efficiently monitoring student progress when teaching chained tasks. The method results in a line graph and response grid which show progress and analyze performance on each step of the task…

Two microcomputer-based laboratories, the motion detector and the sound detector, are discussed in terms of their affects upon the facilitation of an understanding of graphs and their ability to aid in the development of conceptual understanding from graphical analysis. The author relates experiences in using these labs with high school students…

Describes a unitized data system for a scientific database that stores descriptions of individual experimental steps as separate text-based subunits together with appropriate linking signals. Conversion of graphics into searchable text, use of natural language, and cost effectiveness are discussed. An example using a biology research paper is…

Elementary teachers can use graphing to introduce students to one another. An eye color graphing activity helps students learn more about each other while experimenting with different ways of organizing and displaying information. For follow up, students can apply their graphing knowledge by collecting and displaying data from their families. (SM)

Examines the neglect of library support staff within the context of six areas of library management: physical facilities; effective and efficient work stations; supplies; attitude toward human resources; communication and information; and performance evaluation and feedback. Graphs present data on expenditures in several areas, and suggestions for…
