Inspired by the entering of computer algebra systems (CAS) in the Danish upper secondary school mathematics program, this article addresses, from a theoretical stance, what may happen when traditional procedures are outsourced to CAS. Looking at the commands "solve" and "desolve," it is asked what happens when such CAS…

We examine teachers' classroom activities with the spreadsheet, focusing especially on episodes marked by improvisation and uncertainty. The framework is based on Saxe's cultural approach to cognitive development. The study considers two teachers, one positively disposed towards classroom use of technology, and the other not, both of them…

Technology is available and accessible in many mathematics classrooms. Adopting technology to support teaching and learning requires teachers to change their teaching practices. This paper reports the responses of a diverse cohort of 92 secondary mathematics teachers who chose to respond to an Australian state-wide survey (Mathematics with…

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…

Comparison of the effectiveness of two computerized environments, Schemes for Problem Analysis (SPA) and Algebraic Proposer (AP), with two sixth-grade classes found that in solving easy word problems, both software systems were equally helpful, but in harder word problems, those students who learned with SPA experienced more success than those who…

Examines possibilities for learning offered by a piece of software, Fonctuse, likely to encourage the linking of algebraic and graphical representations of functions. Studied the influence of prior algebraic knowledge on the cognitive processes and constructions of knowledge at play in this environment. (Author/MKR)

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)

Two fourth-grade classes served in a study that employed computers for promoting autonomous learning processes through solving challenging problems adapted to students' aptitudes using the number line as an intuitive model. Findings showed that students have preinstructional intuitions and informal knowledge of negative numbers. (24 references)…

Describes and analyzes attitudes of two Portuguese elementary teachers toward mathematics, mathematics teaching, and use of computers in instruction. Semistructured interviews and questionnaires, before and after an inservice LOGO computer course, showed that both teachers changed their attitude, but only one implemented her ideas in teaching. (20…
