Resumo:
The present work sought to evaluate how undergraduate students of a public
Brazilian university located in southern Minas Gerais express their knowledge
about the Nature of Science (NOS) and the Pedagogical Content Knowledge
(PCK) in the development of a teaching material about the history of a physics
concept for Basic Education. We also sought to understand the joint mobilization
between these two types of knowledge to form the PCK/NOS. To carry out this
investigation, didactic materials prepared by 8th period physics undergraduate
students were selected. In all, twelve didactic materials were selected for
analysis, which were complemented with audio recordings of the participants'
presentations about the elaborated didactic materials. For the data analysis, we
investigated the aspects of NOS, PCK and the relations between PCK/NOS
communicated or that can be inferred from the materials. For this, we elaborated
analysis categories related to the visions of elements of NOS and KPC, based on
the references adopted in this research. After performing the analyses it was
possible to identify visions about the NOS, the subcategories of the PCK explicit
in the materials, moments in which the undergraduates mobilize their PCK to
teach elements of NOS (PCK/NOS) and reflections about the use of the History
and Philosophy of Science by the undergraduates as a didactic strategy to
prepare the didactic material. As main results, it was possible to find adequate
and inadequate views about NOS, as well as the majority expression of the
subdomain of Knowledge of Didactic Strategies in Physics Teaching, regarding
PCK. In addition, limitations and difficulties related to this study were identified.
The analyses raised some issues that deserve attention in future research,
among which we can mention training about History and Philosophy of Science
in teaching and the formative practices proposed in initial training.
