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…

A quantitative application of magnetic braking performed with an air track is described. The experimental measurement of the position of the glider as a function of time is calculated. (KR)

Recommends that economics instruction begin a synthesizing process early by connecting discussion of the production possibilities curve and the supply curve. Suggests that linking the two is logical for conveying integrated economic thinking to beginning students. Argues that such a link makes it easier to discuss the competitive norm. (DK)

Presents a diagram for figuring the value of time into an individual's labor-supply decisions and the time intensiveness of the individual's consumption patterns. Seeks to make the integration of differing time values with leisure income choices more understandable for students. (DK)

A student project that investigated the relationship between resting heart beat frequency and body mass of adult dogs is described. The results are compared to those of other mammals and birds. The procedure and results are included. (KR)

Extensions of unidimensional appropriateness indices are developed for multiunidimensional tests (multidimensional tests composed of unidimensional subtests). Simulated and real data (scores of 2,978 students on the Armed Services Vocational Aptitude Battery) were used to evaluate the indices' effectiveness in determining individuals who are…

Presented are activities concerning the method of graphing the equation y=kx in the Cartesian and other coordinate systems. Students progress from the graph of a straight line to the investigation of conceptually related geometric loci in non-Cartesian coordinate systems. (MDH)

The issue of division by zero is discussed. Activities that cover the topics of measurement division, partition division, relationship to fractions, confusion with dividing into zero, dividing zero by zero, and relation to more formal numbers are presented. (KR)

A graphic procedure is presented for studying differential item functioning (DIF) that is designed to provide diagnostic information for psychometricians and educators. The procedure provides a signature of each test item that can be used with a summary statistic to flag items with DIF. Advantages and limitations are noted. (SLD)
