ABSTRACT
We present the results of the characterization of the pedagogical practices of a teacher in a rural public school in the context of confinement by Covid-19. In order to study a specific context, we developed a case study with a Colombian teacher who is responsible for two primary school grades. We inquired about the development of her practices of planning, implementation, and evaluation of teaching for the mathematics area, in three different moments of the confinement period. We conducted semi-structured interviews in which we addressed, for example, the design of activities sent to students and the development of interaction spaces. We also explored the evolution of the affective dimension in the students and the teacher. The results show problems and difficulties the teacher has faced, the solutions she has conceived and implemented, and the successes and failures she has perceived. We present evidence of how the boundaries of standardization of practices were broken when faced with an unanticipated state of confinement. The development of these practices, in a particular reality, has been impacted by difficulties of access to technology and communication resources. The teacher shows how, despite the restricted opportunities in rural areas due to the socioeconomic context of the families, her implementation of actions in addition to the guidelines provided by her institution has contributed to the learning processes and the motivation of her students. © 2023 Czech Ethnological Society.
