Propuestas para introduccíon de nanociencia y nanotecnología en escuelas pre universitarias

Effective pedagogical practices for teaching Nanoscience and Nanotechnology in the pre-university education are suggested. The proposals are based on the scientific and didactical experience of the authors, on the study of the available literature and on a diagnosis of the knowledge and interest of the students. Which was conducted at a pre-university school in the city of Bauru, SP, Brazil.

Analises da nanociência e nanotecnologia na perspectiva de ciência, tecnologia e sociedade cts

In this contribution, we discuss and analyze some aspects of nanoscience and nanotechnology, based on the approach kwon as Science, Technology and Society (STS), as well as the prospects of Philosophy of Technology. In this context, we specify the constitute the nanoscience and nanotechnology analytic research field. I is also reported its genesis and limits, emphasizing the impacts of nanotechnology in the development of the contemporary society, such as the possible benefits and problems associated to the use of nanotechnology, as well as environmental impacts, doubts and uncertainties that permeate this areas, in addition some ethical questions and public policies for the sector are analyzed.

Nanotecnologia e nanociência em livros didáticos de física do nível médio: discursos sobre a tecnologia e a educação científica e tecnológica

In this contribution, we analyze conceptual approaches to nanotechnology and nanoscience in recent issues of secondary education of Brazilian physics textbooks. We analyzed fifteen collections of Physics textbooks of recent editions, however, only two books, belonging to different collections incorporate considerations about nanotechnology and nanoscience in their approaches. We focus our analysis on three aspects, namely: the place dedicated to approaches to nanoscience and nanotechnology, notions about technology and its contributions to critical scientific education. This is a qualitative research; it was used as conceptual approaches the Philosophy of Technology, The Discourse Analysis (DA) and Science, Technology, Society (STS) concepts. We found that in two examined textbooks the approaches to nanoscience and nanotechnology is a complementary description of modern physics, associated with quantum theory. In this context, the concepts of nanoscience and nanotechnology focus superficially in the genesis of the field and some possible areas of applications. It was not identified in all textbooks warnings about the potential risks to human health and the environment from the use of nanotechnology and nanoscience. We understand that textbooks approaches about nanotechnology and nanoscience round a instrumental technological perspective, however keep away from the scientific and technological critical education.
