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)

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)

Nature of science has for a long time been regarded as a key component in science teaching. Much research has focused on students’ and teachers’ views of NOS, while less attention has been paid to teachers’ perspectives on NOS teaching. This article focuses on in-service science teachers’ ways of talking about NOS and NOS teaching, e.g. what they talk about as possible and valuable to address in the science classroom, in Swedish compulsory school. These teachers are, according to the national (...) curriculum, expected to teach NOS, but have no specific NOS training. The analytical framework described in this article consists of five themes that include multiple perspectives on NOS. The results show that teachers have less to say when they talk about NOS teaching than when they talk about NOS in general. This difference is most obvious for issues related to different sociocultural aspects of science. Difficulties in—and advantages of—NOS teaching, as put forth by the teachers, are discussed in relation to traditional science teaching, and in relation to teachers’ perspectives on for which students science teaching will be perceived as meaningful and comprehensible. The results add to understanding teachers’ reasoning when confronted with the idea that NOS should be part of science teaching. This in turn provides useful information that can support the development of NOS courses for teachers. (shrink)

The state of geoscience education, in terms of numbers of teachers, students taught, and perceived importance, has been lagging behind the other science disciplines for decades. Part of the reason for this is that geology is seen as a “derivative” science as compared to its “experimental” counterparts (for instance, physics and chemistry). However, with current global issues facing the populations of the world (climate change, scarcity of clean water, increasing fossil fuel usage), being geoscience literate is a must. We will (...) show that, in fact, the geological sciences have their own philosophical structure, being both historical and hermeneutic, and it is the structure that makes the teaching of the geosciences for addressing such global issues advantageous. In addition, we will explore the use of historical controversies as a pedagogical tool for geoscience instruction. The history of geology is rife with controversy and the use of such a strategy has been shown to be effective for developing students’ interest in the content, sharpening critical thinking skills, as well as emphasizing the nature of science. This chapter consolidates the knowledge base by describing the structure of the geosciences in terms of its philosophical, theoretical, and cognitive frameworks. It highlights four geoscience controversies in terms of these frameworks, all the while reviewing the literature for the use of HPS in geoscience teaching. Finally it contains recommendations for possible future directions for geoscience education research within this context. (shrink)

Understanding nature of science is widely considered an important educational objective and views of NOS are closely linked to science teaching and learning. Thus there is a lively discussion about what understanding NOS means and how it is reached. As a result of analyses in educational, philosophical, sociological and historical research, a worldwide consensus about the content of NOS teaching is said to be reached. This consensus content is listed as a general statement of science, which students are supposed to (...) understand during their education. Unfortunately, decades of research has demonstrated that teachers and students alike do not possess an appropriate understanding of NOS, at least as far as it is defined at the general level. One reason for such failure might be that formal statements about the NOS and scientific knowledge can really be understood after having been contextualized in the actual cases. Typically NOS is studied as contextualized in the reconstructed historical case stories. When the objective is to educate scientifically and technologically literate citizens, as well as scientists of the near future, studying NOS in the contexts of contemporary science is encouraged. Such contextualizations call for revision of the characterization of NOS and the goals of teaching about NOS. As a consequence, this article gives two examples for studying NOS in the contexts of scientific practices with practicing scientists: an interview study with nanomodellers considering NOS in the context of their actual practices and a course on nature of scientific modelling for science teachers employing the same interview method as a studying method. Such scrutinization opens rarely discussed areas and viewpoints to NOS as well as aspects that practising scientists consider as important. (shrink)

The tutelage of our mentors as scientists included the analogy that writing a good scientific paper was an exercise in storytelling that omitted unessential details that did not move the story forward or that detracted from the overall message. However, the advice to not get lost in the details had an important flaw. In science, it is the many details of the data themselves and the methods used to generate and analyze them that give conclusions their probative meaning. Facts may (...) sometimes slow or distract from the clarity, tidiness, intrigue, or flow of the narrative, but nevertheless they are important for the assessment of what was done, the trustworthiness of the science, and the meaning of the findings. Nevertheless, many critical elements and facts about research studies may be omitted from the narrative and become hidden from scholarly scrutiny. We describe a “baker’s dozen” shortfalls in which such elements that are pertinent to evaluating the validity of scientific studies are sometimes hidden in reports of the work. Such shortfalls may be intentional or unintentional or lie somewhere in between. Additionally, shortfalls may occur at the level of the individual or an institution or of the entire system itself. We conclude by proposing countermeasures to these shortfalls. (shrink)

This is an editorial report on the outcomes of an international conference sponsored by a grant from the National Science Foundation to the School of Education at Boston University and the Center for Philosophy and History of Science at Boston University for a conference titled: How Can the History and Philosophy of Science Contribute to Contemporary US Science Teaching? The presentations of the conference speakers and the reports of the working groups are reviewed. Multiple themes emerged for K-16 education from (...) the perspective of the history and philosophy of science. Key ones were that: students need to understand that central to science is argumentation, criticism, and analysis; students should be educated to appreciate science as part of our culture; students should be educated to be science literate; what is meant by the nature of science as discussed in much of the science education literature must be broadened to accommodate a science literacy that includes preparation for socioscientific issues; teaching for science literacy requires the development of new assessment tools; and, it is difficult to change what science teachers do in their classrooms. The principal conclusions drawn by the editors are that: to prepare students to be citizens in a participatory democracy, science education must be embedded in a liberal arts education; science teachers alone cannot be expected to prepare students to be scientifically literate; and, to educate students for scientific literacy will require a new curriculum that is coordinated across the humanities, history /social studies, and science classrooms.

The current study compared the effectiveness of two methods in biology teaching that are based on the science-as-inquiry approach: visits to authentic university laboratories and analyzing adapted primary literature. The methods’ effectiveness was measured in terms of high-school students’ increased understanding following a 6-week intervention that emphasized five major aspects of the nature of science : the tentativeness of scientific understanding, the cooperative nature of the scientific process, methodological diversity, the sociocultural embeddedness of scientific knowledge, and the aims of scientific (...) inquiry. A quasi-experimental, pre-post control design was applied, utilizing quantitative evaluation methods. Findings indicate that teaching NOS in biology high-school classes using science-as-inquiry methods is an effective approach for enhancing NOS understanding. Both of the proposed methods appear to be promising; however, the AUL method was found to be more effective for enabling advanced-level high-school biology students’ understanding of these NOS aspects. In conclusion, both AUL and APL are potentially effective methods that can be adapted for teaching various biology subjects in different cultural contexts. (shrink)

This article presents a study aiming at assessing the efficacy of reading newspaper articles with scientific content in order to incorporate nature of science aspects in initial primary teacher education. To this aim, a short teaching intervention based on newspaper articles was planned and performed under regular class conditions. First, prospective teachers read two newspaper articles related to a recent and controversial scientific research report in the field of physics. Next, they responded reflectively in small groups to various questions related (...) to NOS aspects insinuated in the articles in order for researchers to diagnose their prior ideas about these. Each group then presented their responses in class, and a discussion among groups was encouraged in order to provide feedback. Based on this, the groups revised their initial responses. The evolution of the written responses of the groups was analyzed through an interpretive approach using the methods of inter-rater and intra-rater analysis and low-inference descriptors. The findings showed that these prospective teachers in general improved their NOS views. In the absence of further research, these first findings make evident the pedagogical potential of reading certain newspaper articles for learning about NOS under usual classroom conditions. Finally, some educational implications and perspectives derived from the study are discussed. (shrink)

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)

The didactics of astronomy is a relatively young field with respect to that of other sciences. Historical issues have most often been part of the teaching of astronomy, although that often does not stem from a specific didactics. The teaching of astronomy is often subsumed under that of physics. One can easily consider that, from an educational standpoint, astronomy requires the same mathematical or physical strategies. This approach may be adequate in many cases but cannot stand as a general principle (...) for the teaching of astronomy. This chapter offers in a first part a brief overview of the status of astronomy education research and of the role of the history and philosophy of science (HPS) in astronomy education. In a second part, it attempts to illustrate possible ways to structure the teaching of astronomy around its historical development so as to pursue a quality education and contextualized learning.

A number of authors have recognized the importance of understanding the nature of science for scientific literacy. Different instructional strategies such as decontextualized, hands-on inquiry, and history of science activities have been proposed for teaching NOS. This article seeks to understand the contribution of HOS in enhancing biology teachers’ understanding of NOS, and their perceptions about using HOS to teach NOS. These teachers, enrolled in a professional development program in Chile are, according to the national curriculum, expected to teach NOS, (...) but have no specific NOS and HOS training. Teachers’ views of NOS were assessed using the VNOS-D+ questionnaire at the beginning and at the end of two modules about science instruction and NOS. Both the pre- and the post-test were accompanied by interviews, and in the second session we collected information about teachers’ perceptions of which interventions had been more significant in changing their views on NOS. Finally, the teachers also had to prepare a lesson plan for teaching NOS that included HOS. Some of the most important study results were: significant improvements were observed in teachers’ understanding of NOS, although they assigned different levels of importance to HOS in these improvements; and although the teachers improved their understanding of NOS, most had difficulties in planning lessons about NOS and articulating historical episodes that incorporated NOS. The relationship between teachers’ improved understanding of NOS and their instructional NOS skills is also discussed. (shrink)

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers specializing in physics and chemistry. The approach was explicit and reflective. Three research questions were posed: What conceptions of NOS do the PSSTs show after a first reflective reading of the historical controversy?, What role is (...) played by the PSSTs’ whole class critical discussion of their first reflections on the aspects of NOS dealt with in the controversy?, and What changes are there in the PSSTs’ conceptions of NOS after concluding the activity? The data for analysis was extracted from the PSSTs’ group reports submitted at the end of the activity and the audio-recorded information from the whole class discussion. A rubric was prepared to assess this data by a process of inter-rater analysis. The results showed overall improvement in understanding the aspects of NOS involved, with there being a significant evolution in some cases and moderate in others. This reveals that the activity has an educational utility for the education of PSSTs in NOS issues. The article concludes with an indication of some educational implications of the experience.

Traditional school science has been described as focused on indisputable facts where scientific processes and factors affecting these processes become obscured or left undiscussed. In this article, we report on teachers’ perspectives on the teaching of sociocultural and subjective aspects of the nature of science as a way to accomplish a more nuanced science teaching in Swedish compulsory school. The teachers took part in a longitudinal study on NOS and NOS teaching that spanned 3 years. The data consists of recorded (...) and transcribed focus group discussions from all 3 years. In the analysis, the transcripts were searched for teachers’ suggestions of issues, relevant for teaching in compulsory school, as well as opportunities and challenges connected to the teaching of these issues. The results of the analysis show that the number of suggested issues increased over the years, teachers’ ways of contextualizing the issues changed from general and unprecise to more tightly connected to socio-scientific or scientific contexts, and the number of both opportunities and challenges related to NOS teaching increased over the years. The most evident changes occurred from the beginning of year 2 when the focus group discussions became more closely directed towards concrete teaching activities. Tensions between the opportunities and challenges are discussed as well as how these can be met, and made use of, in science teacher education. (shrink)
