The authors present a scheme for teaching primary grade students about graphing. (SJL)

Graphing techniques are used to demonstrate the inverse function theorem and that the graph of the inverse function can be obtained by flipping the graph about the line y=x. (MP)

An example is given of a problem-solving approach by outlining the development of a generalization of the Pythagorean Theorem as applied to points on a unit circle. (MP)

Presents an investigation using data collected by students to explore timelines and pie charts. The activity begins with having students keep a chronological record of their activities for one 24-hour period to create and analyze pie charts that show how they have spent their time. Activity sheet also included. (ASK)

Describes an activity on data management and statistics in which students were asked to think of a topic and collect information on it to analyze and represent in graphs. (ASK)

Compares observed to expected counts of white, African American, and Hispanic major-league baseball players (n=650) in 1989. Uses chi-square values to determine that racial differences are highly significant for pitcher, catcher, shortstop, and outfielder. Includes appendix with 1993 player counts and seven suggested student activities. (SEW)

Investigations of scientific concepts using inquiry can be included in the traditional college lecture. This lesson uses the Learning Cycle to demonstrate therapeutic drug range, a basic concept in pharmaceutical science. Students use graphing to discover patterns as a part of data analysis and interpretation of provided investigation data.…
