Abstract

There is a large body of literature concerning the potential of dynamic geometry software (DGS) in the problem solving process. However, questions regarding how teaching should take place to prepare students to use DGS as a heuristic tool in non-routine problem situations seem to be overlooked. To address this gap in the literature, the current study aimed to investigate a teaching sequence designed to develop prospective mathematics teachers’ competence to use DGS as a heuristic tool in investigating non-routine geometry problems. To assess the effectiveness of the approach adopted in the study, a homework assignment was used as a data collection tool following a five-week teaching sequence. The students provided three different authentic solutions, all of which exemplified how DGS can contribute to the development of students’ problem-solving skills and support various problem-solving techniques. The study presents the analysis of the students’ solutions, as well as the content of the teaching sequence.
