Considerações sobre as concepções dos professores de ciências e biologia acerca da natureza da ciência

Abstract

The study of several authors shows that generally the conception of Science presented by the teacher is related to his knowledge about the Nature of Science and that such conception almost always influences his teaching practice. Based on this assumption, the main objective of the research was to analyze the conceptions of some teachers of Science and Biology of the public schools of Cruz das Almas-BA on the Nature of Science and how this conception is expressed in its teaching practice. The methodological approach adopted was field research with an qualitative type, which was used of the semi-structure interview as an instrument of data collection, having been carried out with five teachers, of which, two of them work in the teaching of Sciences, two in Biology and one works in Sciences and Biology. The data were interpreted through the analysis of content from Bardin (2011). The results show that both science teachers present an empirical-inductivist and atheistic conception of the Nature of Science and that such conceptions are expressed in their teaching practice; Biology teachers have a more rigid and infallible conception of the Nature of Science that is also expressed in their practice; The teacher who works in the teaching of science and biology, unlike the others, presents a more contextualized conception of the nature of science that is also in his teaching practice. Thus, it is concluded that the results of this study corroborate with the research carried out in recent years, in the country, in which the majority of teachers have deformad conceptions about the Nature of Science and that these are expressed in the teacher's teaching practice, however, there were also exceptions to this type of conception.
