Provides a lesson that focuses on three-dimensional graphing, contours, and topographical maps using computer spreadsheets. (ASK)

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)

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

Discusses an old technique going back to Euler for accelerating the convergence of an alternating series. Uses a computer algebra system such as Derive, Maple, or Mathematica to implement this method called Eulerization. Argues that investigations using this technique will improve a student's understanding of infinite series. (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)

This book presents a numerical problem-solving environment for middle grade students using the computerized spreadsheet. It offers a package of spreadsheet models and suggested activities that promote student thinking with numbers. (ASK)

Examines four areas of difficulty with graphing and modeling, identifies confusions and misconceptions, and shows how these areas interact in the presence of data-collection devices. (KHR)

Argues that teachers and lecturers need to identify essential skills which are technology-independent and need to determine the most effective use of new technology in the classroom. Examines prospects for change using the newer technology of graphing calculators for mathematics courses. Contains 15 references. (ASK)

Presents an activity in which students use mathematical ideas to understand how the intensity of light changes as light passes through water or similar partial barriers, by using a calculator-based laboratory device to record light intensity. Continues with a structured series of questions involving the use of difference equations with which…

Presents activities to demonstrate the use of spreadsheets in mathematics classrooms. Emphasizes writing across the curriculum and interdisciplinary team teaching. Argues that spreadsheets allow students to make projections, comparisons, and contrasts. (ASK)

Argues that interactive geometry computer software connects visual justification and empirical thinking to higher levels of geometric thinking with logical justification in formal proof. Presents classic geometry activities using The Geometer's Sketchpad interactive software. (ASK)

This study investigated the effect of students' ability and type of instructional program, structured and unstructured, on easy and difficult posttest items. Seventh-grade students worked through 14 instructional activities in The Geometer Sketchpad, a dynamic geometry program, and accessed a Geometry tutorial developed to parallel the state…

Stickybear's Math Splash is a CD-ROM-based software tool for teaching mathematics skills beyond simple number recognition to elementary students.

Stickybear's Math Town is a CD-ROM-based software tool for teaching mathematics skills beyond simple number recognition. Accompanying printed lesson plans are designed to complement mathematics skills with other methods and areas of emphasis including kinesthetic learning, listening skills, decision making skills, and other vital tools for…

The concept of function is central in mathematics and grows in importance as one progresses in depth and breadth of understanding mathematics. Results from national assessment progress reports indicate that the majority of students do not comprehend the concepts of function and graphing. Technology has the potential to improve the understanding of…
