This study of seventh graders investigated the use of the calculator in learning conversion algorithms among fractions, decimals, and percents. The calculator was successful with some topics but not with others. (MP)

Four K-12 studies and one for grades 3-4 considered which math topics could be taught most effectively with a hand-held calculator, which new mathematical topics could be successfully introduced when using such calculators, and what the implications might be for problem solving. (Author/LS)

Presents an activity for determining the volume of a solid revolved around an horizontal axis using graphing calculators and computers. (ASK)

Presents historical mathematics to students. Suggests allowing students to have two methods of problem solving with a graphing calculator to allow for a visual result. Indicates that students should have more than one opportunity to experience a solution to a problem, a variety of contexts for the problem, and an opportunity to communicate. (ASK)

Argues that technology influences mathematics education by enabling students and teachers to discover and demonstrate generalizations and properties that were unthinkable a few years ago. Focuses on one example related to a paradox involving parabolas. (DDR)

Presents four activities that use graphing calculators, spreadsheets, and graphing software to model population growth. (MKR)

Presents an activity illustrating the role that technology can play in modeling real-world problem situations and making connections across the curriculum. Includes using a graphical model to answer the questions. Lists related programs for TI-82 and TI-92 graphing calculators. (ASK)

Discusses the implications for teaching of the decision to permit use of graphics calculators in some Victorian Certificate of Education examinations. Also explores the impact of this decision on assessment in mathematics, argues that some amendments should be made to the policy, and looks ahead to the near future when students will have ready…

Presents an insightful approach to algebra that enhances both personal and classroom communication through the process of solving a linear equation. (KHR)

Explains an application of mathematical modeling within a school setting as well as progressive use of graphing calculators in mathematical modeling. Analyzes students' performances in the process of problem-solving using the problem of baton-passing in relay races. Discusses students' use of their mathematical knowledge and ideas when they used…

Data were analyzed to see if a correlation or relationship existed between students' grades in a course and students' rankings of the professor's teaching. Graphing calculators allowed students to visualize relationships between the data and to compute the equation of the regression line, compute the correlation coefficient, and test statistical…

Presents ways of using theories of knowing and learning to inform use of computer algebra systems (CAS) in school and early college mathematics. Describes the role of macroprocedures and microprocedures, process-object distinctions, and the movement towards more formal ways of expressing mathematical ideas. Discusses how these theories along with…

Recounts the experiences of faculty members as they addressed some of the challenges presented in choosing and integrating a new technology, the TI-89 hand-held computer algebra system (CAS), into the core mathematics curriculum. Relates in detail deciding which instrument to choose, instructing students to use the technology, affecting the…

Studied the effects of calculator use on performance on the Scholastic Assessment Test I through a questionnaire completed by 202,391 examinees in 1996 and 215,034 in 1997. Use of calculators was associated with higher performance, but the more able students were more likely to have calculators. Overall, the effects of calculators were found to be…

Evaluates the effectiveness of calculator usage in the learning of basic skills by developmental mathematics students with respect to increasing mathematical performance, as measured by a "no calculator permitted" content specific test. Results show calculator usage neither positively nor negatively affected the attainment of basic skills.…
