Seeking a historical-philosophical approach to science teaching, narrative texts have been used as pedagogical tools to improve the learning experience of students. A review of the literature of different types of narrative texts and their different rates of effectiveness in science education is presented. This study was developed using the so-called Historical Narrative as a tool to introduce science content from a historical-philosophical approach, aiming to discuss science as a human construction. This project was carried out in a 9th grade (...) Physics class in K-12 school, in Rio de Janeiro, Brazil. The steps involved in constructing a Historical Narrative based on the controversy over animal electrical fluid between Luigi Galvani and Alessandro Volta is reported herein. Finally, qualitative research results of the activities inspired by this Historical Narrative are presented with the purpose of answering the research question: to what extent do Historical Narratives support and enhance discussions about the Nature of Science, through teaching the scientific content in a historical-philosophical approach with 9th grade students? The results indicate that Historical Narrative, based on historical episodes, is a good “door opener” to teach scientific content in a historical-philosophical approach, introducing discussions about the Nature of Science without neglecting the scientific content or simplifying the discussions about the NOS.

Research in science education has recognized the importance of history and philosophy of science (HPS), and this has facilitated the evaluation of science textbooks. Purpose of this chapter is to review research based on analyses of science textbooks that explicitly use a history and philosophy of science framework. This review has focused on studies published in the 15-year period (1996–2010) and has drawn on the following major science education journals: International Journal of Science Education, Journal of Research in Science Teaching, (...) Science Education, and Science & Education. Based on HPS-related criteria, 52 articles were selected for review, and of these 28 were published in Science & Education, which clearly shows the importance of HPS for this journal. Selected articles were classified in the following subject areas depending on the textbooks analyzed: university biology textbooks (n = 2), university chemistry textbooks (n = 14), university physics textbooks (n = 17), and primary, secondary, and high school textbooks (n = 19). Results obtained revealed the following: (a) Most biology, chemistry, physics, and school science textbooks lack a history and philosophy of science perspective; (b) most of the textbooks analyzed were published in the USA and to a much lesser extent in other countries; (c) few studies provided details of the procedure and reliability of the application of criteria/rubric for analyzing textbooks; (d) some of the topics analyzed in the textbooks were nature of science, atomic structure, Newtonian mechanics, quantum mechanics, special theory of relativity, and evolution; (e) textbooks avoided including controversial and difficult aspects of different topics (e.g., concepts of force, weight, heat, temperature, origin of the quantum hypothesis, oil drop experiment, Millikan’s data supported Einstein’s photoelectric equation but not his theory); and (f) various science topics provide an opportunity to illustrate the tentative nature of scientific knowledge, and still very few textbooks referred to this important aspect. As textbooks do refer to laws and theories while referring to historical content, it is concluded that HPS is already “inside” the science curriculum provided textbook authors make an effort to scrutinize the historical reconstructions while dealing with the different topics.

The inclusion of the history and philosophy of science in science teaching is widely accepted, but the actual state of implementation in schools is still poor. This article investigates possible reasons for this discrepancy. The demands science teachers associate with HPS-based teaching play an important role, since these determine teachers’ decisions towards implementing its practices and ideas. We therefore investigate the perceptions of 8 HPS-experienced German middle school physics teachers within and beyond an HPS implementation project. Within focused interviews these (...) teachers describe and evaluate the challenges of planning and conducting HPS-based physics lessons using collaboratively developed HPS teaching materials. The teachers highlight a number of obstacles to the implementation of HPS specific to this approach: finding and adapting HPS teaching material, knowing and using instructional design principles for HPS lessons, presenting history in a motivating way, dealing with students’ problematic ideas about the history of science, conducting open-ended historical classroom investigations in the light of known historical outcomes, using historical investigations to teach modern science concepts, designing assessments to target HPS-specific learning outcomes, and justifying the HPS-approach against curriculum and colleagues. Teachers' perceived demands point out critical aspects of pedagogical content knowledge necessary for confident, comfortable and effective teaching of HPS-based science. They also indicate how HPS teacher education and the design of curricular materials can be improved to make implementing HPS into everyday teaching less demanding. (shrink)
