Practice proves that students tend to face difficulties in learninggeometry. This observation is partially confirmed by the results of educationalresearch as well as external exams. It happens repeatedly that studentsget lower marks in arithmetic or algebra tasks. The causes of such situationare complex. One of the reasons is that teaching geometry requires specialteaching skills characteristic for...
One of the main goals of mathematical education is to develop the skills for problem solving as well as skills that help carry out mathematical reasoning and argumentation.Geometric problems play here a special role. These require the person solving them to act with an inquiry attitude and a ‘specific vision’. The ‘specific vision’ is the ability one can manipulate with geometric objects in ones’...
This research addresses elementary school prospective teachers’ education in geometry and takes place in Portugal, in the context of a geometry course taught by the first author of this paper. We aim to characterize the activity of prospective teachers in defining quadrilaterals as they work on exploratory tasks in a design-based research study for a geometry course at the 2nd year of their teacher...
