Describes a competency based business mathematics course offered at Spokane Falls Community College (Washington) in which students, through the use of calculators, master mathematical concepts without having to mentally add columns of figures or perform complex arithmetic problems on paper. Examines both the mathematical and 10-key skills…

The results of this study indicate no significant differences on two achievement tests and one aptitude test between calculator and non groups. Nevertheless, the investigator notes several advantages of using the calculator. (MK)

Activities are described in which number patterns in two-digit multiplication exercises are investigated. (DT)

Recommendations of several publications with regard to the use of hand-held calculators in the mathematics curriculum are presented. Relevant portions of the NACOME and Euclid Conference reports are cited as well as a report to NSF and recommendations from an NIE/NSF conference. Recommendations support expanded use of, and research concerning,…

Describes projects for high school physics classes that use computer tools including integrated software packages, graphing calculators, and calculator-based lab and microcomputer-based lab. Sites available on the World Wide Web are discussed and specific examples of experiments based on Galileo and Newton are included. (LRW)

Describes a study that examined three areas of student assessment in a college algebra classroom (i.e., oral interactions, observations, and problem-solving investigations) before and after the use of graphing calculators in class activities. Reports that the use of the calculators enhanced the teacher's assessment practices in all three areas.…

Tells stories of children in their first year of school (mostly age five) who were using calculators for the first time. Implications are that children's thinking moves from a rough to a more thorough and refined grasp of the whole. Learning mathematics with calculators is more like the learning of language than traditional classroom mathematics.…

Consideration of a definite integral in an advanced calculus class led to a great deal of mathematical thinking and to the joy of discovery. Graphing calculators allowed students to investigate quick solutions which should be regarded as stepping stones to additional investigation and rigorous proof. With slight modifications to their proofs,…

In revisions due to be implemented in 1994, the Scholastic Aptitude Test (SAT) will emphasize critical reading skills and mathematical computation more, and test takers will be allowed to use calculators. The College Entrance Examination Board's Achievement Tests will also be overhauled, with new subject tests added and current test format and…

Three activities which require a calculator with integer division capabilities are presented. In each activity, procedures and questions for discussion are included. Game boards, samples, and answers are included where appropriate. (CW)

Describes a course including both theory and practice in the uses of calculators and microcomputers for secondary school mathematics teachers. Provides four calculator activity sheets and an evaluation questionnaire. (Author/YP)

Develops an experimental teaching method emphasizing the nature of functions including graphical representation in an introductory college physics course (mechanics). Examines the effects of this method on student's problem solving and attitude toward physics. (YP)

Interviews with elementary and secondary principals (n=28) and teachers (n=209) about calculator use in mathematics classes in 1990 found that use of calculators remained largely unchanged from 1979, and calculators used were becoming more varied and sophisticated, although few teachers had used graphing calculators.

Presents Texas Instruments' new Calculator-Based Laboratory (CBL), a hand-held device that connects to a graphing calculator, as a tool to make sophisticated measurements outside the classroom laboratory. Describes activities that use the CBL to make measurements in motion studies. (JRH)

Describes the use of the TI-82 graphics calculator as an intermediate step in introducing computers to the high-school physics lab. Discusses linking the calculator with other machines so that students can save data, enter programs on a computer and later download to the calculator, and transfer graphs to a computer for printing.
