The article focuses on the analysis of curriculum documents from Taiwan to investigate how benchmarks for learning nature of science are positioned in different versions of the science curricula. Following a review of different approaches to the conceptualization of NOS and the role of NOS in promoting scientific literacy, an empirical study is reported to illustrate how the science curriculum documents represent different aspects of NOS. The article uses the family resemblance approach as the account of NOS and adapts it (...) for analysis of the curriculum documents. The FRA defines NOS as cognitive-epistemic and social-institutional systems that serve as constructs of knowledge categories with a high level of interconnectedness. The FRA was used as an analytical tool for investigating two sets of Taiwanese curriculum guidelines published 10 years apart, providing an opportunity to discuss how NOS is addressed in the curriculum reforms. The findings show a shift away from the excessive centralization of the cognitive-epistemic system to a consideration of the social-institutional system. Modifications to the benchmarks are proposed in order to achieve a more holistic and progressive approach to NOS. The article contributes to studies on NOS in science education by illustrating how the FRA can act as a tool for exploring interconnectedness of NOS ideas in the curriculum. (shrink)

This article is about an intervention introducing prehistoric life in primary education. Its objectives were to foster openness and interest for prehistory and archaeology, as well as content knowledge and conceptual learning with a focus on four main facets: basic knowledge about prehistoric life; conceptual learning/change regarding prehistory; learning about archaeologists and archaeology as a scientific discipline; and learning about interactions of archaeology and other disciplines. Students participated in two workshops about the creation of a prehistoric object, highlighting the close (...) interaction between the natural sciences and humanities within archaeology. The workshop emphasised dialogue between students, teachers and researchers, as well as active participation by the students. The educational effects of the workshops were studied using a pre-post design. Results show that the workshops had sizeable positive effects on both affective and cognitive variables. The appreciation of the workshops ranged from ≈ 70 to 90% for interest, perceived educational value and further aspects. We also found a positive impact of the intervention on cognitive variables, e.g. for several elements of key knowledge about prehistory. Regarding conceptual learning, we found improved understanding of the link between climate change and long-term changes in wildlife in a given area. A positive impact was also found for the understanding of archaeology encompassing both humanities and the natural sciences. No differences of the various outcomes were found between girls and boys; the workshops appear suitable for both genders. We conclude with a discussion of the interpretation of our findings, of some limitations and possible improvements, and of future perspectives, in particular for further classroom implementation.

This article presents and discusses an innovative pedagogical device designed for training pre-service teachers on the nature of science. We endorse an approach according to which aspects of the nature of science should be explicitly discussed in order to be understood by learners. We identified quantum physics, and more precisely the principles of uncertainty and complementarity, as a rich topic suitable for such a discussion. Our training device consists in preparing and staging a new type of theater, the “scientific experimental (...) theater,” based both on the characteristics of Brecht’s theater and Kelly’ cyclic theory of learning. This device was implemented with a group of eight pre-service teachers. According to our observations, the approach favors their involvement and provides them with a frame for expressing their doubts and confronting their points of view. By analyzing their discussion, we identified several aspects of the nature of science that the pre-service teachers raised spontaneously: subjectivity, the social and cultural embeddedness of science, the construction and status of models, and the role of questioning in the development of science. The implemented device therefore appears as an interesting means for stimulating a rich discussion on the nature of science. This study opens new avenues for teachers’ and students’ training devices aimed at developing a critical and reflective stance on science. (shrink)

Science education researchers have long advocated the central role of the nature of science for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological issues associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. One particularly promising method for teaching NOS involves an explicit (...) and reflective approach using the history of science. The purpose of this study was to determine the influence of a historically based genetics unit on undergraduates’ understanding of NOS. The three-class unit developed for this study introduces students to Mendelian genetics using the story of Gregor Mendel’s work. NOS learning objectives were emphasized through discussion questions and investigations. The unit was administered to undergraduates in an introductory biology course for pre-service elementary teachers. The influence of the unit was determined by students’ responses to the SUSSI instrument, which was administered pre- and post-intervention. In addition, semi-structured interviews were conducted that focused on changes in students’ responses from pre- to post-test. Data collected indicated that students showed improved NOS understanding related to observations, inferences, and the influence of culture on science. (shrink)

This article describes the effect of a teaching–learning sequence based on the discovery of oxygen in promoting students’ argumentation. It examines the written and oral arguments produced by 63 high school students in France during a complete TLS supervised by the same teacher. The data used in this analysis was derived from students’ written responses, audio and video recordings, and written field notes. The first goal of this investigation was to provide evidence that an approach combining history and philosophy of (...) science and argumentation could increase students’ awareness of the relevance of experimentation and communication to scientific progress. The second goal was to assess the effectiveness of the TLS to engage students in argumentative classroom interactions relating to the discovery of oxygen at the end of the 18th century. The findings show that this historical case can be useful for promoting students’ argumentation and is also appropriate for high school students. Future research should include students of other ages, other historical episodes and experiences in other parts of the world. (shrink)

Educators advocate that science education can help the development of more responsible worldviews when students learn not only scientific concepts, but also about science, or “nature of science”. Cosmology can help the formation of worldviews because this topic is embedded in socio-cultural and religious issues. Indeed, during the Cold War period, the cosmological controversy between Big Bang and Steady State theory was tied up with political and religious arguments. The present paper discusses a didactic sequence developed for and applied in (...) a pre-service science teacher-training course on history of science. After studying the historical case, pre-service science teachers discussed how to deal with possible conflicts between scientific views and students’ personal worldviews related to religion. The course focused on the study of primary and secondary sources about cosmology and religion written by cosmologists such as Georges Lemaître, Fred Hoyle and the Pope Pius XII. We used didactic strategies such as short seminars given by groups of pre-service teachers, videos, computer simulations, role-play, debates and preparation of written essays. Along the course, most pre-service teachers emphasized differences between science and religion and pointed out that they do not feel prepared to conduct classroom discussions about this topic. Discussing the relations between science and religion using the history of cosmology turned into an effective way to teach not only science concepts but also to stimulate reflections about nature of science. This topic may contribute to increasing students’ critical stance on controversial issues, without the need to explicitly defend certain positions, or disapprove students’ cultural traditions. Moreover, pre-service teachers practiced didactic strategies to deal with this kind of unusual content. (shrink)

These reflections range over some distinctive features of the journal Science & Education, they acknowledge in a limited way the many individuals who over the past 25 years have contributed to the success and reputation of the journal, they chart the beginnings of the journal, and they dwell on a few central concerns—clear writing and the contribution of HPS to teacher education. The reflections also revisit the much-debated and written-upon philosophical and pedagogical arguments occasioned by the rise and possible demise (...) of constructivism in science education.

Fen eğitimi ve öğretiminin anahtar unsurlarından bir tanesi bilimin doğasının ve özelliklerinin doğru bir şekilde tespit edilmesidir. Bilimin doğasına yönelik tespitler fen eğitimi yöntemlerini birçok açıdan etkilemektedir. Fen eğitimi ve fen öğretimi ile ilgili olan kişiler bilimin doğasının açık bir şekilde öğretilmesi gerektiğini kabul etmektedir. Thomas Kuhn’un bilim tarihi, bilim felsefesi ve bilim sosyolojisi alanlarını içeren incelemeleri neticesinde ileri sürdüğü bilimin yapısına, işleyişine ve doğasına yönelik tezleri (paradigma, olağan bilim, bilimsel devrimler, eşölçülemezlik, bulmaca çözme, kuram seçimi, keşif ve gerekçelendirme ayrımı) (...) fen eğitimi ve öğretimi alanında sıklıkla başvurulan kaynaklar olmuştur. Bu doğrultuda makalede mantıkçı pozitivist bilim anlayışının bilimin nesnel, evrensel, kesin gerçekleri ortaya çıkaran, sosyal-kültürel değerlerden ve ön yargılardan bağımsız, bilimsel bilginin birikimsel bir şekilde ilerlediği yönündeki iddiası bilimin gerçek doğasını yansıtamadığı düşüncesiyle Kuhn’un görüşleri çerçevesinde tartışılmaktadır. Makalenin temel savı Kuhn’un bilime ve bilimin doğasına yönelik tespitlerinin bilimin gelişen, dönüşen ve değişen yapıdaki gerçek doğasına vurgu yaptığı ve böylece fen eğitiminde sıklıkla başvurulan bilimin doğasına yönelik kavrayışı dönüştürdüğüdür.

The “practice turn” in philosophy of science has strengthened the connections between philosophy and scientific practice. Apart from reinvigorating philosophy of science, this also increases the relevance of philosophical research for science, society, and science education. In this paper, we reflect on our extensive experience with teaching mandatory philosophy of science courses to science students from a range of programs at University of Copenhagen. We highlight some of the lessons we have learned in making philosophy of science “fit for teaching” (...) outside of philosophy circles by taking selected cases from the students’ own field as the starting point. We argue for adapting philosophy of science teaching to particular audiences of science students, and discuss the benefits of drawing on research within science education to inform curriculum and course design. This involves reconsidering teaching resources, assumptions about students, intended learning outcomes, and teaching formats. We also argue that to make philosophy of science relevant and engaging to science students, it is important to consider their potential career trajectories. By anticipating future contexts and situations in which methodological, conceptual, and ethical questions could be relevant, philosophy of science can demonstrate its value in the education of science students.

As part of a teacher training project, 16 future chemistry teachers participated in a dramatisation activity, in which they discussed a controversy concerning an event from the history of science: the awarding of the Nobel Prize in Chemistry to Fritz Haber in 1918. Preparations for the role-play activity, the dramatisation of the mock trial, and the subsequent discussions were video-recorded. We also collected the written material produced by the pre-service teachers and the reflective journals they produced during their involvement with (...) the activity. This article discusses the contributions of such an experience to future teachers’ knowledge on aspects related to both nature of science and argumentation, as well as to their views on their future actions related to authentic teaching of and about science. The results show that such contributions were meaningful. (shrink)

A new chronology is introduced to address the history of chemistry, with educational purposes, particularly for the end of the twentieth century and here identified as the fifth chemical revolution. Each revolution are considered in terms of the Kuhnian notion of ‘exemplar,’ rather than ‘paradigm.’ This approach enables the incorporation of instruments, as well as concepts and the rise of new subdisciplines into the revolutionary process and provides a more adequate representation of such periods of development and consolidation. The fifth (...) revolution developed from 1973 to 1999 and is characterized by a deep transformation in the very heart of chemistry. That is to say, the size and type of objects, the way in which they must be done and the time in which they are transformed. In one way or another, chemistry’ limits had been set out. (shrink)
