Research has often found little or no significant differences in overall performance for math students using graphing calculators compared to traditional (non-calculator) classes. However, when performance is divided into procedural and conceptual levels, significant differences appear at the conceptual level. This study investigates the relation…

Several studies have shown the difficulties students encounter in making sense of situations involving rate of change. This study concerns how students discover errors and refine their knowledge when working with rate of change. The part of the study reported here concerns the responses of four precalculus students to a task which asked them to…

In a high school writing workshop, students frequently would go through multiple essay drafts and conferences with the teacher and fellow students before realizing that their theses were incorrect. A teacher devised the "lexivision" to address this problem. Students used Venn diagrams, graphs, or flow charts to represent concepts in the…

This investigation of cognitive effort begins with a review of cognitive principles relating to memory and graphic encoding of information. The cognitive framework described allows explanation of improved memory due to reparsing of graphic representations. It also provides the basis for optimizing graphical material design to insure best retention…

A demonstration project was undertaken to determine whether 1978 telefacsimile technology could address the needs of rural public libraries in a cost-effective manner. The TALINET design utilized local public library staff and a research/resource information staff at the University of Denver to research questions and deliver information to five…

For decades, every chemical engineer has been asked to have a background in separations. The required separations course can, however, be uninspiring and superficial because understanding many separation processes involves conventional graphical methods and commercial process simulators. We utilize simple, user-­friendly mathematical software,…

This profile provides data from the 1980 census on American Indians, Eskimos, and Aleuts in the total U.S. population, on American Indian reservations, and in historic areas of Oklahoma (excluding urbanized areas). Bar graphs illustrate data on (1) the overall population; (2) population by geographic region; (3) population by standard federal…

The advent of calculators for graphing and function plotters is changing the way college algebra and calculus are taught. This paper illustrates how the machines are used for teaching the following: (1) domain and range; (2) product and quotient inequalities; and (3) the solving of equations. Instructional hints are provided for each topic with…
