APLICAÇÃO DO MODELO DO CONHECIMENTO DAS CIÊNCIAS PARA O ENSINO DA CÉLULA - UM ESTUDO DE CASO INSTRUMENTAL (Applying the model of science knowledge for teaching about cell - an instrumental case study)

摘要: This research results from an Instrumental Case Study, based on the Professional Knowledge (PK) Model, defined by Ball et al. (2008, 2009) for area of Math. The Modelserved as basis building Model Content ScienceTeaching, which was used to evaluate teaching practice two teachers Natural Sciences and Mathematics. study seeks understand, analyze discuss knowledge shown when dealing with unit “Cell: unity in constitution Living Beings”. Thus, we intend identify enabled contentsassociated cells classroom understand how why such is present or absent. To information emerging classroom, use Modeling Instrument Monteiro 2009), allows transcriptionof classes, line line, splitting it into episodes subepisodes. division facilitates identification dimensions teacher's knowledge, according Science Teaching. As a result, clear that most active Common (CCK). Finally, implication awareness about professional (PK), pedagogical content (PCK), relationships between them, Teaching reflection process teaching.
