“…Any learning situation is subject to the possibility of assuming errors and these should be used in favor of learning Over the years, interest in studying errors has increased and initially this type of research was more focused on students than on teachers ( Tulis , 2013, Heinze and Reiss, 2007, Santagata , 2005. Today this reality has progressively changed; Research that addresses errors in teachers being trained has increased, however, those that study errors and other aspects related to practicing teachers have not been as abundant (Aguerrea, Solís and Huincahue , 2022 ;Gómez and Restrepo, 2015;Heinze and Reiss, 2007, Santagata , 2005and Tulis , 2013Rhoads, Radu and Webber, 2011) and much less, in the case of teacher educators, key actors that have been little studied ( Contreras, 2021;Parra-Sandoval, 2020;Chick and Beswuick , 2018). Therefore, any research on error that focuses on these two populationspracticing teachers and teacher educators -can provide significant data for learning processes and this is the case that concerns us in this paper.…”
