Discusses the meaning of calculation errors, describing two error types (truncation and roundoff errors). Examples of calculator calculations are given to illustrate the importance of an awareness of significant digits and the effects of errors that may lead user to a mistaken interpretation of calculated results or to faulty conclusions.…

Provided are some ideas on teaching elementary numerical methods to sixth-form students. Comments are included on the syllabus recently introduced at Advanced Level in Hong Kong. (MNS)

An approach to equation solving using calculators that promotes the trial-and-error method as a useful strategy when combined with calculators is presented. The approach is specifically geared towards the secondary schools as a way of moving to harder equations that the linear and quadratic ones traditionally used. (MP)

Discusses uses of calculators and microcomputers in mathematics education with particular reference to their impact on the teaching and learning of mathematics in Hong Kong schools. Indicates that teacher training in software design and production is essential because of the lack of adequate, well-designed mathematics software. (Author/JN)

Describes a course including both theory and practice in the uses of calculators and microcomputers for secondary school mathematics teachers. Provides four calculator activity sheets and an evaluation questionnaire. (Author/YP)
