Resumo
This study presents the application of three-mediated activities that use of investigative cases (IC) as situations for teaching chemistry, which are anchored in the light of the notion of relationship with the knowledge. All the cases were worked in higher education courses at the Federal University of Tocantins - Campus of Gurupi as integral parts of both disciplines. The first IC was applied in the discipline of Fundamentals of Analytical Chemistry and saw the participation of twelve students from the Environmental Chemistry course (EC) and twenty two undergraduate students from Bioprocess and Biotechnology Engineering (BBE), dividing the class in twelve group (G1 to G12). The second and third activity were planned in the course of Instrumental Analytical Chemistry with the participation of sixteen students (S1 to S16) and fourteen students (S1 to S14) of the sixth semester of the EC course, respectively. We make use of participatory research to conduct all activities and the narratives for data collection. The categorization of the paths taken by students during the resolution of the case was realized by content analysis and to analyze the process of learning chemistry was used the notion of relationship with knowledge. The analysis of the narratives allowed: identify and categorize the strategies and actions used by students throughout the activity, as well as unveiling the relations with knowledge that prevail in each category; and list the ways that students take ownership of chemical knowledge present in the cases. Thus, our results indicate that in all activities there was the appropriation of chemical knowledge, whichever the description of phenomena or chemical process whereas the level of ownership among students differs according to the relationship with themselves during the activity. In addition, we observed that the concepts of mobilization, questioning teacher, relationship of knowledge, network of meanings and normativity, present in the notion of relationship with the knowledge, enable to guide, to lead, to block and to support the analysis of the learning process of concepts chemical intrinsic to cases applied.
