A Process of Modeling the Cell Membrane in Biology Teacher Training at University

Abstract: The study is contextualized in a University teacher training program of Biology, in a perspective that proposes that disciplinary training spaces in biology developed by the students should be informed and intervened by models and teaching strategies coming from training spaces in the didactics of natural sciences. Results of a cell membrane modeling process are presented based on the analysis of a scientific fact. Initial models by the students are characterized, as well as the process of intermediate modeling and the structuring of the membrane model, in particular the aspects of fluidity and self-assembly of the molecules that compose it. The analysis of the productions allows us to infer that the initial models made for the proposed situation were becoming more complex and allowed for the theoretical reconstruction of the phenomenon, anchored in the scientific reference model.
