Abstract
In this paper we analyze a set of textbooks used in Brazilian high school to evaluate how the historical context is presented when it comes to bacterial transformation, which is an important historical episode for DNA recognition as a hereditary molecule. In addition, we used the epistemology of Ludwik Fleck (1896-1961) to further analyze this historical context. Only four of the ten books presented the episode of bacterial transformation. As we turn to the epistemological analysis, we found that historical contextualization presented in these four books is sometimes described in a decontextualized and linear way, making it impossible for the student to assimilate not only science as a human and collective production, but the social aspects involved in producing scientific knowledge according to Fleck’s writings: thought style, exchange of ideas, complications and transformations, as well as coercion in terms of hegemonic thought in the area.
