GUMIERO, Bárbara Silva  e  PAZUCH, Vinícius. The Planning of Geometry Tasks and the Mobilization of Teaching Professional Knowledge. Ciência educ. [online]. 2021, vol.27, e21025.  Epub 19-Jul-2021. ISSN 1980-850X.  https://doi.org/10.1590/1516-731320210025.

The planning of tasks, one of the teacher's duties, causes the mobilization of knowledge. In this article, the aim is to understand the dimensions of teachers' knowledge that constitute the planning of tasks involving geometrical concepts. Thus, a group with collaborative characteristics was constituted, where four tasks were planned. The discussions held in the group were analyzed based on the Knowledge Quartet, a theorical analysis tool composed of four dimensions of knowledge, among them the foundation, which is the main dimension identified. It was observed that the knowledges mobilized were related with the knowledge of the content and pedagogy. The codes awareness of purpose and identification of errors were identified at first. In the planning of the development of the task, codes related to procedures, terminology, use of the textbook, and use of digital technologies were mobilized. Peer collaboration in the planning of tasks has afforded teacher education in, for, and with the school.
