This South African study explored how pre-service teachers understand concepts in analytical geometry. Extending the work of Skemp and Carrillo-Yañez, et al., we captured data and carried out this qualitative study. We noted that the participants displayed complete understanding for some geometrical concepts but lacked relational understanding. Their learning process was interrupted during the covid epidemic, and this had a negative impact on their relational understanding of geometric concepts.
Zulu et al. (Fri,) studied this question.
