This article presents 12 examples of the use of a calculator in the algebra class. The calculator codes and the mathematical formulas of the examples are presented in the appendix. (Author/YP)

Discusses the use of graphing calculators for polar and parametric equations. Presents eight lines of the program for the graph of a parametric equation and 11 lines of the program for a graph of a polar equation. Illustrates the application of the programs for planetary motion and free-fall motion. (YP)

Discusses the geometrical array of the keys on a calculator that can be turned into a problem-solving, problem-posing situation for the upper elementary or middle school classroom. Provides figures showing the arrays, including rows, diagonals, crosses, rhombi, angles, and squares. Lists seven references. (YP)

The Core-Plus Mathematics Project (CPMP) is a four-year program emphasizing mathematical modeling, featuring full use of graphing calculators, building on the theme of mathematics as sense-making, and involving investigations of real-life contexts that lead to reinventing important mathematics. (MKR)

Surveys of (n=80) elementary school principals assessing the nature and extent of technology use in elementary mathematics and science found that teachers used microcomputers more in mathematics than in science, and microcomputer and calculator use was more common in intermediate grades than in primary grades. (28 references) (Author/MKR)

Examines the relationship between experience and philosophical orientation by identifying practicing teachers' (n=233) and preservice teachers' (n=78) contextual frameworks related to calculator use as expressed through Habermasian interest categories. Found philosophical orientation pertaining to calculator use was a function of both experience…

A key obstacle to using educational technology is limited support for teachers trying to integrate unfamiliar techniques into instruction. Research-verified technologies include calculators, distance education, drill and practice (CAI) systems, laser videodiscs, microcomputer-based labs, presentation software, and telecommunications. Emerging and…

Raises and responds to questions about what and how to teach mathematics with the availability of calculators to all students. Discusses whether students need basic facts, mechanical skills, and knowledge of computational algorithms. Argues that students need to develop number sense and analytical skills using simple, symbolic, and graphing…

Discusses the rationale and a method for the instructional use of graphing calculators as an intermediary step between the intuitive notion of the concept of a limit and its formal epsilon-delta definition. (JJK)

Seven junior high students with educable mental handicaps were trained to solve four-column subtraction problems involving regrouping. Results in performance favored calculators over pencil and paper, with rehearsal and visual cues influencing performance for only one student. With calculators, subjects' performances were equivalent to a…

Discusses areas where teachers may harbor mistaken assumptions about their students' understanding when using graphing calculators: (1) confidence and competence with order of operations, (2) integration of algebraic and graphical knowledge, and (3) scaling a graph. (MKR)

Challenges mathematics instructors to use graphing calculator technology in courses designed for non-mathematics majors and offers three types of open-ended problems that can be integrated into a basic skills mathematics curriculum: simultaneous equations, distance problems, and proportions using real data. (MKR)

Presents an overview and discussion of some results of research on the use of graphing calculators organized into the following categories: (1) achievement studies, (2) conceptual understanding, (3) problem solving, (4) classroom dynamics, and (5) future research needed. (29 references) (MKR)

The hand-held graphing calculator allows high school mathematics students to graph complex equations that would otherwise take hours of tedious work. This article presents high school mathematics teachers' opinions on its use in lower and upper level math courses. (SM)

Presented is a conversation with students that gives an insight into the ways students think about decimals. Students were introduced, with the use of a calculator, to decimal notation and systematic experimentation. What students had learned throughout this conversation is discussed. (KR)
