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)

Promotes the use of the microcomputer in mathematics instruction, reviewing approaches to teaching nonlinear equations. Examples of computer diagrams are illustrated and compared to textbook samples. An example of a problem-solving program is included. (ML)

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)

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.…

Synthesized are a number of learning theories (those of Piaget, Bruner, Gagne, Dienes and Skemp) to form one composite teaching-learning model. This model is then applied to mathematics teaching. An example is provided to illustrate how the model may be used to elaborate a teaching-learning scheme for solving quadratic equations. (Author/DS)

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)
