Abstract:

In today's world, where contact teaching is not safe or not allowed at all, education is moved to online space. Teachers need to adapt to new educational opportunities. It is still important to attract the attention of students, to be able to explain the curriculum in understandable, engaging and interesting way. It is necessary to look at the current situation as a challenge and make the most of it. In this way, a real educator can show their art and abilities. Classical teaching used so far has long been considered obsolete, but this discipline is still important for the development of spatial imagination and the ability to ‘see’ for students of technical fields. However, the step from classical teaching to modern interactive geometry is challenging for the teacher. The current situation has forced teachers to make changes. In this paper, we discuss teaching methods in an undergraduate level course of Descriptive Geometry at a technical university during forced online education. The computer-aided construction of geometric shapes brings new possibilities that were not available in the classical construction with a pencil on paper or chalk on a blackboard. It is a long known saying, one look is worth a thousand words. If we allow students to engage in geometry, change the assignment and follow the results, we will achieve a deeper understanding of spatial relationships. Interactive geometry is therefore one of the possible ways to continue the education of geometry.
