Project duration

2017 - 2020


In project 2 the teacher-student interaction in secondary school geometry lessons is simulated. Teacher-student interaction in secondary school geometry classes will be simulated in a video-based simulation environment to determine the mathematical reasoning skills of students.
In funding phase 1, three studies were carried out in which the prerequisite profiles of diagnoses and the effects of prompts on the acquisition of diagnostic skills were examined.
