Over the past decade, research on the use of technology in the mathematics classroom has focused primarily on issues of student learning and engagement. In this article, we focus on middle grades mathematics teachers' use of The Geometer's Sketchpad, and study both the decisions they make about when to use technology, and their motivations for…

This paper reports on a study that examined if it is possible to start teaching algorithmic problem solving as early as elementary school, given the condition that studying mathematics is augmented by suitable use of computer technology. Three pre-service teachers, enrolled on a course on algorithmic problem solving in mathematics and who were…

The aim of this paper is to contribute to the understanding of the possible influence of the use in class of Internet resources which offer mathematical exercises for the students' activity and learning processes. I present an exploratory study grounded on a teaching design set up in two French grade six classes about proportional reasoning…

T-algebra is a project for creating an interactive learning environment for expression manipulation tasks of elementary algebra. Our main didactical principle has been that all the necessary decisions and calculations at each solution step should be made by the student, and the program should be able to understand the mistakes. This paper…

In this paper, difficulties of students in the case of computer-mediated teaching of geometry in a traditional classroom are considered within the framework of "transactional distance", a concept well known in distance education. The main interest of this paper is to record and describe in detail the different forms of "distance" during students'…
