How the students chased perpendicular lines in GeoGebra Classroom
Original language description
This paper focuses on the issue of what solution strategies do secondary school students provide while performing non-standard geometric constructions. For this purpose, we developed an interactive electronic environment in GeoGebra Classroom and, in that environment, we let students construct perpendicular lines in multiple ways. We formulated the task for students so that it corresponded with their school geometry curriculum but in a non-standard open-ended way. Then we analyzed students' constructions qualitatively. Findings showed that the students were usually able to solve the task but just a few of them were able to generate multiple strategies. However, creative constructional approach appeared in data indicating the significance of the assignment or instruction where a variety of mathematical approaches are possible.
