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)

Describes several activities and games that provide an introduction to the concept of function. Suggests that experiences should depend more on students' experiences and understanding and less on the memorization of unmotivated conventions with abstract symbols. Includes activities for a calculator as a function machine, composite functions, and…

Presents a lesson on the scale of the solar system that focuses on measurement, exponential notation, proportionality, and ratios. (Contains 17 references.) (Author/ASK)

Promotes the use of logistic modeling in high school and early college mathematics, to compare this model to commonly used models, and to give an alternative to the TI-83 built-in logistic-regression key method when that method fails to converge or gives an inappropriate model. (ASK)

Presents two programs for the TI-83 to conduct the chi-square goodness-of-fit test in an elementary statistics course or any other course that might require students to conduct hypothesis tests relative to some frequency distribution. (ASK)

There is ample evidence that positive involvement of families in children's learning can be a major contribution. Where to start is often a challenge, however, especially in the numeracy area. As part of the Australian Government's "Numeracy Research and Development Initiative" a team led by Beth Powell in Western Australia has developed…

This paper presents an easy and free online tool that has visually enhanced teachers' writing-response pedagogy and helped their students comprehend their composing. Create a Graph is a free and intuitive online data-graphing program developed by the National Center for Education Statistics. In three clicks a visual depiction of weaknesses or…

This instructor guide, which was developed for use in a manufacturing firm's advanced technical preparation program, contains the materials required to present a learning module that is designed to prepare trainees for the program's statistical process control module by improving their basic math skills and instructing them in basic calculator…

This paper documents how eight high school students in a precalculus class enhanced with graphing calculators think about functions. Three models of thinking about functions emerged from students' function images observed over a period of 9 months. In the graph model, students believed that functions are essentially graphs; in the equation model,…

This yearbook focuses on the role of technology in school mathematics. Chapters are replete with classroom-tested ideas for using technology to teach new mathematical ideas and to teach familiar mathematical ideas better. Chapters included: (1) "Using the Graphing Calculator in the Classroom: Helping Students Solve the "Unsolvable" (Eric Milou,…
