Using ePortfolios in mathematics learning is a valuable way to visualise students' learning outcomes in student-driven learning. ePortfolios are typically a collection of finished or fixed artefacts. However, several new software applications offer the opportunity to incorporate the interactive and dynamic characters of mathematics and…

This paper describes a study aimed to identify most common impediments related to the introduction of an open-source mathematical software package GeoGebra. We report on the analysis of data collected during a three-week professional development programme organised for middle and high school teachers in Florida. The study identified challenges…

The use of Computer Algebra Systems (CAS) is becoming increasingly important and widespread in mathematics research and teaching. In this paper, I will report on a questionnaire study enquiring about mathematicians' use of CAS in mathematics teaching in three countries; the United States, the United Kingdom, and Hungary. Based on the responses…
