Takes a theme from "IMPACT Maths" and works it into a spreadsheet activity to display data in bar charts, pie charts, and line graphs. (ASK)

The mathematical curriculum of the next millennium should harness children's motivation without losing their mathematics. Envisages that the computer might offer just the context to help do this. Presents snapshots from two case studies. (Contains 18 references.) (ASK)

Presents ways of using different software for visualizing sampling distributions from a variety of background distributions. Random numbers are used to produce samples of given size and the mean of each is calculated. The mean and standard deviation of these means are calculated, a grouped frequency table is produced, and a histogram is generated.…

Discusses the use of the Excel computer program to develop and distribute simple models that provide a clear visual representation of a chosen probability distribution's properties to students. (ASK)

Focuses on two teachers who had made no use of DERIVE with their classes but who agreed to make regular use of DERIVE with one of their classes over the course of one year. Presents teachers' accounts of what they did. Discusses time issues in using DERIVE, the use of materials, pressures on teachers that influence their use of DERIVE, and the…

Analyzes the results of a Mexican/British project that used the sociocultural approach to investigate ways in which mathematics is used in the practice of school science and the role of spreadsheets as a mathematical modeling tool. Suggests the possibility of enhancing students' capability to shift between a wider range of representations using…

Studies two children working in the context of specially developed computer microworlds with a teacher/researcher for approximately 45 minutes a week for 50 weeks over a two-year period. Indicates that the operations and unit types associated with the children's whole-number sequences did not interfere with the reorganization of their fractional…

Illustrates attempts by three students to construct an isosceles triangle in Cabri and the construction of a capital A by a fourth student. Discusses Cabri's potential for encouraging students to focus on geometric properties and develop correct geometric language. (ASK)

Presents a student mathematics project aimed at developing students' skills with computer spreadsheets and using the Internet to give students an appreciation of the many ways that mathematics can describe common everyday items--in this case the bicycle--and make them aware of their own role in learning. (ASK)

Presents an analytic framework to describe and analyze students' answers to proof problems. Employs the framework to investigate ways in which dynamic geometry software can be used to improve students' understanding of the nature of mathematical proof and improve their proof skills. (Author/MM)

Reports on the Partnership for Excellence in Teacher Education (PETE), an NSF-funded project to promote reform in mathematics and science teacher preparation that features the redesign of teacher preparation to reflect current research on learning and teaching. Concludes that new tools of technology have the potential for enhancing education but…

Presents seven mini-lessons on chaos theory and fractal geometry for use in a high school setting. Examples include the Sierpinski Triangle and Julia Sets. (MM)

Computers were invented to help mathematicians perform long and complicated calculations more efficiently. By the time that a computing area became a familiar space in primary and secondary schools, the initial motivation for computer use had been submerged in the many other functions that modern computers now accomplish. Not only the mathematics…

The Department of Mathematics at the University of Food Technology, Plovdiv, Bulgaria, has introduced the Computer Algebra System DERIVE into the Mathematics courses with a view to increasing student motivation and understanding of the material taught as well as the efficiency of the teaching process. With the aim of investigating the effect of…

This article outlines a linear regression activity that engages learners, uses technology, and fosters cooperation. Students generated least-squares linear regression equations using TI-83 Plus[TM] graphing calculators, Microsoft[C] Excel, and paper-and-pencil calculations using derived normal equations to predict the 2004 presidential election.…
