This article shows the application of the ratio concept to the working of a 10-speed bicycle using a formula and tables. Two references are listed. (YP)

A generalization of the golden ratio is made, called the silver ratio. Some examples where the golden ratio appears are provided so that the silver ratio appears. (MNS)

Examines factors related to computer anxiety measured by the Computer Anxiety Index (CAIN). Achievement in two programing courses was inversely related to computer anxiety. Students who had a home computer and had computer experience before high school had lower computer anxiety than those who had not. Lists 14 references. (YP)

This is an overview of changes that occurred in the mathematics curriculum in the six states of Australia, including Queensland, New South Wales, Victoria, South Australia, Western Australia and Tasmania. Changes related to goals, syllabus, guidelines and evaluation are described. (YP)

Discussed are trends in British mathematics education with special attention to practice. The importance and proper use of practical work, student-led activities, and matching instruction to student ability are emphasized. Lists 9 references. (YP)

Investigated was a sequence of computer-based activities on estimation with 108 students in grades 9, 10, and 12. The activities were appropriate for students at each grade level; each class improved their estimation scores significantly. (MNS)

Five series of mathematics textbooks for grades seven and eight were examined to see the kinds, amounts, uses, and suggestions for writing included. Few writing activities and very few longer writing tasks were found. (MNS)

Describes a writing unit which coincided with an algebra unit on solving problems with two variables, in which students wrote down their reasons for choosing a particular multiple choice response, expressed an equation in writing, and wrote a six paragraph description of the solution to a problem. (RS)

Investigates teachers' roles and conceptions by analyzing choices taken by mathematics teachers when faced with curriculum reform induced by introducing informatics, educational technology, in secondary school courses. (Author/MKR)

Focuses on the place of discrete mathematics in the grades 9-12 mathematics curriculum and discusses how the topic of recursion should be taught. Presents several examples of recursion involving LOGO, spreadsheets, sequences, Pascal's triangle, and the Tower of Hanoi to illustrate its teaching. (MDH)

Presents an example of the use of historical materials in developing the concept of logarithm. A description of the unit includes the origins of the word logarithm and the objectives, organization, and implementation of the unit. The historical development establishes the connection between arithmetic and geometric progressions and logarithms.…

Researchers collaborated with secondary science and mathematics teachers to better understand their constraints when trying to navigate change. Teachers read various national reform documents, discussed change, then generated action projects exploring what they gleaned from the readings. Researchers found that teachers were more unsure about what…

Presents a lesson combining statistics, algebra, and economics in which students create their own mathematical functions and make inferences from those functions. Students learn about the relationships among profit, revenue, and cost. Includes reproducible student group report form. (MKR)

Presents a classroom mathematics project for preservice teachers or secondary school students in which students investigate roughness or ruggedness of the boundaries of a state. (MKR)
