El manejo de las escalas como obstáculo epistemológico en la divulgación de la nanociencia

Abstract

This paper considers three main ideas. First, the notion of epistemological obstacle (EO) proposed by Bachelard, which considers that during science teaching, the learners have their own personal explanations about the world, that function as real epistemological obstacles (EO). These EO impair the understanding of scientific knowledge. The second one is that nanoscience and nanotechnology are becoming common aspects of daily life, but where the perception of nanoscales functions as real EO that interferes with is comprehension. And third, it is considered that in informal science education environments such as science museums, it is possible to detect those EO, due to the nature of the interaction between the visitors and the exhibits. In this paper an empirical research is presented, aiming to set a proposal to work with the EO represented by nanoscales.
