Widmer, Connie; Sheffield, Linda – Learning & Leading with Technology, 1998
U.S. mathematics education has been criticized for being too broad. This article examines ways middle school students use simple problems and situations to foster a deeper understanding of underlying concepts. Presents a sample area and perimeter problem, describes extending the problem using tiles to determine minimum perimeter, and discusses…

Cortes-Figueroa, Jose E.; Moore, Deborah A. – Journal of Chemical Education, 1999
Describes the use of Calculator-Based Laboratory (CBL) technology and a projectable TI-83 graphing calculator to demonstrate the kinetic behavior of a complex reaction. Explains how the CBL is used to review first-order reactions and the graphing calculator is used to determine the rate constants for a series of consecutive first-order reactions.…

Ellington, Aimee J. – School Science and Mathematics, 2006
Forty-two studies comparing students with access to graphing calculators during instruction to students who did not have access to graphing calculators during instruction are the subject of this meta-analysis. The results on the achievement and attitude levels of students are presented. The studies evaluated cover middle and high school…

Cassity, Constance L. – 1997
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…

Laughbaum, Edward D. – 1989
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…

DiSchino, Mary; Sylvan, Laura; Whitbeck, Christopher – 1996
This document features the experiences of three science teachers who video and audiotaped classroom proceedings in order to go back over what was said in classroom events, to explore the intentions and ideas that were perhaps not fully understood at the time. Mary DiSchino, who teaches 3rd and 4th graders, teaches a science curriculum which she…

Saurino, Dan R.; Bouma, Amy; Gunnoe, Brenda – 1999
This study evaluates the use of graphing calculators in the science classroom within the context of a collaborative action research approach. A class of diversified middle-class students (n=650) defined by teachers and administrators as "above average" were studied. Initially, information was gathered on current classroom management techniques as…
