Abstract:

The teaching of geometry in primary and secondary schools is very atypical compared to other areas. Pupils/Students solve design problems with available technical means on paper in direct teaching or draw in available software. However, there was a problem during the pandemic as teachers did not have a blackboard and their drafting tools and scanning a chalk or marker board would have been of poor quality. Design problems have loose or bound assignments, if students have a bound assignment, complications arise in some cases. In researching this issue, it was found that students and pupils have difficulty in the basic auxiliary construction of a set of points from which a line segment can be seen at a given angle. This paper will point out what may have caused this ignorance, which is also found in tertiary education. The paper will also include an introduction to the technical resources available to help with the teaching of geometry during the pandemic. The issue can be viewed from the perspective of hardware or software technical resources. It will be presented some concrete examples for future math teachers (lower upper secondary level) and also primary school teachers, which can be helpful in mathematics education during the pandemic sitation.
