Professional teachers development through a constructivist approach: didactic contexts,

The present paper discusses the partial results obtained from a research that aimed professional development courses for primary and secondary school teachers, under a constructivist and hands-on approach. The intention was to analyze how teachers grasp knowledge under such context, what difficulties emerge and what situations favour their learning process, as well as to study the consequences of professional development courses on their classroom practices. Thirteen teachers participated on workshops during which the investigation of electrostatic phenomena was proposed and low cost experimental apparatus were built, and simultaneously teachers had the opportunity to reflect and analyze their pedagogic practices. The methodological approach of this investigation was qualitative, data were collected with records of oral and written outcomes from researched subjects, as well as records of researchers observations. The learning context generated in those workshops enabled the identification of both conceptual and linguistic difficulties, along with other learning forms, such as action learning and group action learning. Metacognition processes fostered a critical view upon the mechanisms of scientific knowledge acquisition. It is assumed that the experience and the analysis of situations that are similar to those proposed to students might favour an isomorphism with future classroom actions. This professional development proposal seems promising as to consolidate methodological changes arisen from teachers new models and conceptions, different from those regarded as traditional. The analysis of the data regarding the reflections on teachers practices and how the transposition of methods and contents to classrooms happened indicate to this sense and will be covered in a future paper
