The authors provide a framework to aid instructional decision-making regarding classroom calculator use. The guide focuses on both teacher goals and the students' needs and abilities. The reader is challenged to rethink the possible role that calculators can serve for all students, in particular, as a classroom accommodation for students with…

Graphic tips for using the Geometer's Sketchpad (GSP) are described. The methods to import an image into GSP, define a coordinate system, plot points and curve fit the function using a graphical calculator are demonstrated where the graphic features of GSP allow teachers to expand the use of the technology application beyond the classroom.

Placement tests are rapidly joining the ranks of high-stakes testing and college freshmen are required to take mathematics placement exams to determine their first mathematics course upon entering college. Unfortunately, these exams tend to place students in a lower-level or remedial course. As a result, additional expenses are incurred, degree…

This article outlines a linear regression activity that engages learners, uses technology, and fosters cooperation. Students generated least-squares linear regression equations using TI-83 Plus[TM] graphing calculators, Microsoft[C] Excel, and paper-and-pencil calculations using derived normal equations to predict the 2004 presidential election.…

Undergraduate students (N = 47), enrolled in 2 separate psychology research methods classes, evaluated a power analysis lab demonstration and homework assignment. Students attended 1 of 2 lectures that included a basic introduction to power analysis and sample size analysis. One lecture included a demonstration of how to use a computer-based power…

One problem that students have with mathematics is that they often view the topic as a series of unrelated ideas. Sometimes they are aware that they have to know one concept to move to the next, but what is done in geometry is not necessarily related to anything in algebra. This failure to recognize mathematical connections limits students'…

Discusses the significance of the simple, inexpensive type of calculator as a tool in the classroom and the contribution of the more sophisticated type to the school science department. (GS)

It is noted that calculator usage is increasing and that little information was found on the effect of calculators on learning mathematics in elementary school. The activities described and included are intended to be examples of ways in which calculators may be used with existing curriculum materials. It is assumed that each teacher would select,…

Seven activities are presented in this student workbook designed for an exploration of small business ownership and the use of the calculator in this career. Included are simulated situations in which students must use a calculator to compute property taxes; estimate payroll taxes and franchise taxes; compute pricing, approximate salaries,…

The calculator is used to explore the distributive property of a unary operator over a binary operator. This is an extension of an earlier paper. The emphasis is on student discovery of the property for various combinations of the operators. Instructional material contained in the report include a reference sheet of questions for potential…

The self-instruction office machines course provides both student's and teacher's manuals and includes, in the teacher's edition, scripts to be used with 21 instructional sound films for the machines covered. These may be used without the films as detailed operating instructions. The teacher's manual also contains instructions on operating each…

This study compares the effectiveness of an electronic calculator, programmed as an immediate feedback device, with the effectiveness of pencil-and-paper exercises without immediate feedback for the learning of the 100 basic multiplication combinations. These two methods were also compared with regular classroom procedures. Subjects were…

Argues the failure of calculators to show significant numbers only predicates a re-evaluation of the types and uses of electronic calculators in schools. (CP)

A method for finding any integral root of a number using a four-function calculator is given, along with a justification of the method and root-finding exercises. (MN)
