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)

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)

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 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,…

Many believe that technology offers the most benefit to students and teachers when it is integrated into the core curriculum rather than being taught as a separate discipline. This publication is intended to assist teachers in incorporating technology into learning activities in mathematics and science. Chapters emphasize issues concerning…

The introduction of technology resources into mathematics classrooms promises to create opportunities for enhancing students' learning through active engagement with mathematical ideas; however, little consideration has been given to the potential for technology to promote a more collaborative approach to learning. This paper draws on data from a…

Education has traditionally studied the world by bringing it into the classroom. This method can result in situated learning that appears to students to have no relevance outside the classroom. Students acquire inert, decontextualized knowledge that they cannot apply to real problems. The obvious solution to this shortcoming is to reverse the…

Describes a rugby problem designed to help students understand the maximum-minimum situation. Presents a series of explorations that locate an optimal place for kicking the ball to maximize the angle at the goalposts. Uses interactive geometry software to construct a model of the situation. Includes a sample student activity. (KHR)

Outlines several recommendations for teaching probability in the secondary school. Offers an activity that employs simulation by hand and using a programmable calculator in which geometry, analytical geometry, and discrete mathematics are explored. (KHR)

An approach to finding the rational roots of polynomial equations based on computer graphing is given. It integrates graphing with the purely algebraic approach. Either computers or graphing calculators can be used. (MNS)

Compares the trends of women's and men's world records for the 800-meter run using the linear and power regression capabilities of a graphing calculator. (MDH)

Reports on the use of technology to enhance the teaching of ordinary differential equations, gives examples of laboratory activities using cooperative learning, and discusses assessment of student learning. MacMath, TI-81 graphing calculators, and Maple were used in the course. (Author/MKR)
