Unidade, diversidade e continuidade celular: repensando o ensino de células no ensino médio

Abstract

This work was the object of study cell teaching and concepts related to it, investigating the processes resulting from the use of an educational material to work with this subject at the secondary level. In these terms, the aim of this study was to develop and investigate a series of focused educational activities in the concepts of unity, diversity and continuity, linked to socio-scientific issues, the inclusion of the subject stem cells, to see if such activities can promote the teaching of students average ownership of cell concept and the concepts related to it and the development of a critical consciousness. To collect information, which served for the construction of the proposed research data, they were used to store and record the teaching / learning processes that occur during the development of teaching notes sequence of activities in logbook and audio recordings and video, as well as a questionnaire to high school students. Data were transcribed and analyzed using an approach microgenetic analysis, which focuses on analysis of processes and not products. Favors also a way of building data that requires attention to detail and trimming interactive episodes between the subjects participating in the research. During the development of research attention was arrested on interactions between subjects, the elaborations and conceptual developments collectively constituted, from the discourse between the subjects and the development of knowledge, to evaluate the sequence of activities as mediator object in the teaching / learning cells. The results above show that the teaching activity sequence can contribute as a teaching material for the cell teaching and concepts related to it, as long as changes are made that suited to the realities of each group of people and the mediator appropriates the methodological concepts, teaching and proposed cell in this sequence, providing improvements in teaching and learning of this content, the average level through the discussion of how to teach cells.
