Explores the effects of varying the coefficients in the general quadratic function using graphing calculators. (MKR)

Discusses a method of graphing polar equations using information from the Cartesian graphs of trigonometric functions. (MKR)

Investigates the relationship between a fourth-degree polynomial function's parameters and its graph. (MKR)

Gives an example of one danger of using graphing software without an accompanying mathematical analysis by illustrating what might happen if a student were capable of dealing with the drawing of the complete graph of a function only by using a technological tool. (MKR)

Describes the learning experiences of young children meeting stem-and-leaf plots for the first time. Presents a vignette that offers a real and dynamic example of how young children can learn, use, and evaluate this powerful statistical display. (Author/ASK)

Presents examples in which the graphing calculator can provide students with particularly valuable insights into some major statistics ideas such as random numbers. (ASK)

Reports the results of an informal study of very young children's reactions to some visual displays of data. (Author/ASK)

Presents an activity in which students learn how to label graphs in order to make them meaningful. (ASK)

Pre- and posttests and interviews concerning misconceptions and alternate conceptions of rates of change were administered to (n=42) students in first-semester calculus using a conceptually-motivated curriculum. Suggests that an emphasis on visual representations through construction and interpretation in conjunction with teacher-student analysis…

This publication provides examples that illustrate how school psychologists might use graphs to improve communication of their perceptions, data, and understanding of clients' behavior to parents and students, and to other educators. The booklet is divided into two parts. Part I presents 15 graphs which were sent to school psychologists in Iowa…

A graphing activity which allows students to work independently of the teacher and the textbook is described. The activity involves providing data in order to develop the skills necessary for interpreting the collected information. (JT)

Library user guides from seven large academic libraries were examined for readability using microcomputer software for analysis. Results indicated that most guides are written at or above a reading level of grade 12. Appendices summarize readability formulas and depict in a composite graph the levels of all of the guides examined. (16 references)…

Provides an algorithm for determining the median and quartiles of discrete data sets. Describes the graphical equivalent of the numerical method. (JM)

Reasons for having students make graphs are noted. Then specific graphing topics and materials appropriate for young learners are presented, including life-sized, floor, clothespin, felt-face, block, and magnetic graphs, and polls of pupils. (MNS)

Teachers of an integrated elementary classroom used cookie-sharing time as a learning experience for students. Responsible for dividing varying amounts of cookies daily, the students learned to translate their experiences to graphs of differing sophistication and analyses. Further interpretation and application were done by individual students…
