| 總結: | The article presents an analysis of the teaching work of teachers of the Degree in Mathematics of the Pedagogical and Technological University of Colombia, which can be considered as a starting point to improve classroom practices. The theoretical approach is that of class models proposed by Porlán, complemented by Piaget’s classical constructivism, Vygotsky’s socio-cultural approach, and Bruner’s interactionism. The research methodologyis mixed, with a descriptive scope. The instruments used to collect information were questionnaires and unstructured interviews. The results show that most of the teachers who participated in the research: design their classes based on operational objectives; assess through the application of objective tests, posed especially as guides; and consider that learning occurs through a progressive process of concept assimilation. According to the aforementioned, it is evident that the characteristics of teachers’ practices are associated with a technological didactic tendency.
