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)

Calculators are transforming mathematics instruction, freeing it from an arithmetic-driven curriculum. They have encouraged teachers to think more carefully about what is important to learn. Calculators should be used at all levels of instruction and on tests, including standardized exams. Meaningful educational reform depends on such a change.…

Within the next two decades, calculators will be standard tools in mathematics classrooms. They should be used regularly but carefully in classroom instruction and testing to allow use of realistic data and exploration of mathematical concepts, but not to allow finding the answer without understanding the question.

Reports that as the number of students required to complete developmental mathematics courses increase, faculty turn to the American Mathematical Association of Two-Year Colleges (AMATYC) standards as guidelines for better instructional methods. Describes the necessity for educators to decide how graphing calculators can be used most effectively…

Describes approaches taken with concepts associated with exponential functions by using graphing calculators to provide students with concrete meaning for the sometimes abstract concepts involved and to link students' learning with their existing knowledge. (ASK)

Describes a study designing and implementing technology-based investigations and evaluates their impact on student learning. Discusses a teacher's mediation of the students' use of technology through curriculum materials, and considers some attributes of computers and graphics calculators that determined which tool was selected for each…

Presents activities to model dynamic systems using graphing calculators and calculator based laboratories. (Author/ASK)
