Calls for the use of the zoom feature of graphing calculators to help students better understand the concept of derivatives. (MKR)

Discusses mathematics as analogous to a tree with many branches. Contends that technology, especially the graphing calculator, can help students see the sun and sky through the many branches and leaves. (MKR)

Presents an investigation of a third-degree polynomial using a TI-82 graphing calculator. Also includes an algebraic solution. (MKR)

Presents an experiment carried out at the University of Groningen where pretest-posttest design was used including two experimental conditions with the graphics calculator (TI-81) and one control condition without the calculator. Results point toward a change in teacher instructional behavior and in pupils' problem-solving approaches. Contains 14…

Presents an investigative process of conjecture followed by proof by induction using a combination of manipulatives and technology, placing special emphasis on the use of different representations. (ASK)

Describes the implementation of graphing calculators as teaching and learning aids in an intermediate linear algebra unit at the undergraduate level. Outlines the approach taken and discusses the problems that arose in relation to calculator use. (ASK)

Focuses on three activities using the TI-92 graphing calculator that examine the relationship between the intensity of a light source and its distance from a measurement point, properties of a sound wave, and the relationship between the time elapsed and the temperature of a cooling substance. (ASK)

Describes an activity in which students investigate the symmetry of factor sets of composite numbers using the TI-83 graphing calculator. This activity allows students to observe patterns, make predictions, and verify their accuracy. (ASK)

Presents a lesson that uses a motion detector in order for students to experience the interplay between motion and its graphical representation of the slope. Focuses on the change in the appearance of the graph with regard to changing speed. (ASK)

Discusses the graphing and other technical capabilities of the TI-83. Demonstrates possible uses of it in mathematics classrooms. (ASK)

Presents a study on calculus reform that examines how instructional approaches that place different emphases on the use of technology and multiple representations impact undergraduate calculus students' ability to use and understand connections between different representations of concepts. Compares three courses--traditional calculus, calculus…

Identifies and describes some of the mathematics curriculum issues associated with graphing calculators such as equity, role of calculators, content and sequencing, textbook design, learning to use a calculator, worksheets, student decision-making, calculator dependence, assessment, electronic algorithms, multiplying choices, calculator…

The abstract nature of the mole and its applications to problem solving make learning the concept difficult for students, and teaching the concept challenging for teachers. Presents activities that use concept maps and graphing calculators as tools for solving mole problems. (ASK)

Reports on a study replicating and extending a previous study examining the effects of the TI-92 graphics calculator and calculus instruction on students' success in calculus. Finds that students using a TI-92 had significantly better performance on the final exam and overall course grade than students using other calculators, and student-centered…

Showcases applications of mathematics designed to demonstrate to students how the topics under study are used in the real world or to solve problems. Presents an activity on thermal systems using spreadsheets or graphing calculators. (ASK)
