The Cabri programming language is a dynamic geometry software used all around the world by many of teachers, students, and researchers in mathematics. This paper presents examples of using Cabri and graphing calculators as a tool to practice mathematics and provides ways that mathematics could be approached, taught, and received in a way…

Students undertaking mathematics courses in their final year of secondary education in Victoria are assessed using a combination of school based coursework assessment and examinations. Over the last decade, students have used technology such as graphics calculators, statistical software, spreadsheets, and computer algebra systems (CAS) extensively…

A Maryland middle-school teacher can no longer imagine a math classroom without computers, word processing programs, graphing calculators, graphic design programs, and colored printers and monitors. Aided by these devices, her students made great leaps toward the 21st-century technology goals spelled out by the Department of Education in 1995.…

Presents an activity for constructing and solving radical equations which can be done with or without the use of graphing calculators. Highlights one method that two students used to solve radical equations. (ASK)

Presents an experiment to design a precalculus topic that would help prepare students for limits in differential calculus. Emphasizes the topic to enhance the interpretation of graphs and to be applicable in both technology-based and traditional precalculus courses. Uses graphing calculators to help students observe the results of their…

Presents a study designed to explore whether a student's use of the graphing calculator during instruction will affect their concept of function, how students' participation in a conceptual change assignment affects their concept of function, and how the graphing calculator and the conceptual change assignment interact with one another to…

Analysis of observations in precalculus classrooms in which graphing calculators were integrated with the curriculum found evidence that students and teachers shifted their roles when technology was in use. (Author/MKR)

Explores ways in which various technologies can be integrated to teach the transformation of graphs in an interactive and dynamic way. Discusses how the use of graphic calculators, a spreadsheet, graph plotter, presentation package, and an interactive whiteboard can be combined to give students the opportunity to investigate, understand, and have…

Describes a calculator-based lesson designed to use technology as a tool to enhance students' conceptual understanding of functions. (KHR)

Covers a project conducted by the Freudenthal Institute in which observation of student behavior supported the premise that the graphics calculator can stimulate the use of realistic contexts, the exploratory approach to mathematics, a more integrated view of mathematics, and more flexible behavior in problem solving. (AIM)

Presents an exploration of conversation in a single episode of a 12th grade girls' calculus class. Analyzes Habermasian communicative competence which requires students to show critical thinking and the ability to express their views. Explains learning outcomes by teachers' mode of questioning, cooperative endeavor by students, instructional…

Presents a method for determining the coordinates of the endpoint of a line segment given its slope, point of origin, and length. Applies the notion of similar triangles to quickly solve this type of problem. Includes a calculator program. (KHR)

Reviews the use of chi-square statistics for goodness of fit. Examines how to help students relate their earlier work with independence to the use of chi-square statistics. (KHR)

Discusses the focusing effect of technology as a way of systematically accounting for the role of technology when students form ideas that are unexpected and unwanted by teachers and designers of the technology being implemented. Includes examples of university students using graphing calculators and mathematics software and considers implications…

Describes a variety of activities to develop ideas of pattern, mapping, and graphing for high-level high school mathematics classes. Provides problems and their answers with screen displays for the Casio graphic calculators. (YP)
