In this study, the effect of using on-screen calculators on eighth grade students' performance on two TIMSS 2019 Problem Solving and Inquiry Tasks items considered as examples of technology-enhanced items administered on computers was examined. For this purpose, three logistic regression models were run where the dependent variables were giving a…

In this paper, we report a pilot study on engaging a group of undergraduate students to explore the limits of sin(x)/x and tan(x)/x as x approaches to 0, with the use of non-graphic scientific calculators. By comparing the results in the pretest and the post-test, we found that the students had improvements in the tested items, which involved the…

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)

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)
