A Science Teacher Researcher in his Pedagogical Knowledge/Practice

This research was developed in the context of a Teacher Training program entitled ＂Science and Citizen Awareness Project (PCCC),＂ suggested and developed by its author. The proposals were applied to a group of science educators from the Cruz Alta/RS/Brazil Municipal Education Network, accompanied by their respective pedagogical supervisors and school administrators, developed in 2011 and 2012 in monthly meetings, totaling 80 hours of classroom instruction. The methodology employed was based on a theoretical/bibliographic survey of pedagogical strategies, starting from a theoretical foundation anchored in Thomas Kuhn’s conception of science, David Ausubel’s educational conception, and Philippe Perrenoud’s methodological conception. It was followed by an investigation of the profile and preconceptions of the target audience regarding their knowledge and practices in science. and, based on the proposal and development of activities called Educational Technologies, such as Scientific Literacy, Concept Maps, Experimental Activities, and Problem Solving, aimed to consolidate a Science Teaching that is based on and developed through Research.
