Documents students' use of Cabri-Geometry to work on tasks that led them to construct particular relationships and explore and connect different mathematical themes or ideas. (Author/MM)

Both computers and calculators are limited by architecture, operating system, and software, to some predetermined level of precision within decimal number presentation and calculation. However, there exists a base that produces a terminating decimal. (MM)

It is surprisingly easy to explore geometry using Word AutoShapes or an Excel spreadsheet. Most of the techniques described could be taught to Y7 in half an hour. Many of them could be used in primary schools. Shows some of the mathematical possibilities of these techniques. Detailed step-by-step worksheets to introduce pupils to these are…

Demonstrates a less utilized feature of the TI-92+: its natural and powerful programming language. Shows how to implement several linear algebra related algorithms including the Gram-Schmidt process, Least Squares Approximations, Wronskians, Cholesky Decompositions, and Generalized Linear Least Square Approximations with QR Decompositions.…

Investigates the impact of the TI-89 hand-held Computer Algebra System (CAS) on student achievement in a first year college core calculus course. Analyzes data from an experimental study conducted at the United States Military Academy at West Point from 1998-2000. Results indicate that the TI-89 hand-held CAS experimental group attained a higher…

Compiles observations from a multivariable calculus class in which computers were used extensively. Results show that visualization skills can be improved and that students use technology in very innovative ways. (Author/MM)

Illustrates two ways of exploring the properties of cubic polynomials. The first exploration uses a Computer Algebra System (CAS) to help students understand an important part of mathematical history, the discovery of an algorithm to find the roots of a cubic equation. The second exploration states some conditions required for a curve and finds a…

Describes a research and development project whose main focus is the use of Computer Algebra Systems (CAS) in mathematics classrooms and the didactical possibilities linked with its use. Focuses on the possibilities and problems of cooperation between theory and practice and between mathematics educators and teachers. (Author/MM)

Reviews examination questions and categorizes them according to their usefulness in a Computer Algebra System (CAS) environment with respect to their significance for testing abilities and skills and from the point of view of using a CAS for their solution. Examination questions are presented as an important didactical tool in teaching…

Examines the ways in which social work educators who are interested in Web technology but not expert in its applications can use the World Wide Web. Current opportunities and challenges in integrating technology into social work education are discussed, and future directions in the use of technology are explored. (EV)

Urges the environmental education community to recognize that the time is ripe for educators to embrace education reform initiatives based on the National Science Education Standards, and the development of promising Internet resources for teaching environmental sciences. (Author/MM)

Describes a new instructional framework, Internet Workshop, designed around three themes reflecting how literacy is changing. Notes that the Internet Workshop consists of an independent reading of information on the Internet around a topic and a location initially designated by the teacher; it concludes with a short workshop session where students…

Examines the impact of educational technology on student performance by reviewing the extent to which classroom computers are oversold and underused. The review concludes that the lack of computer use in teaching, even when computers are present, stems from technology promoters ignoring teachers' motivations, needs, and institutional constraints.…

Discusses pre-college access and use of computers by different groups of students, cross-campus computing initiatives, the potential impact of the present inequities experienced by students of color in the context of cross-campus computing, and recommendations to enhance access to computers and the computer competence of students of color. (EV)

Computer algebra systems have great potential uses, but learning the basic concepts of algebra is itself a mathematical activity. Explores theoretical concepts that may be seen as essential enabling skills for computer algebra systems users. (Author/ASK)
