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 focuses on the impact of a professional play that we developed in order to introduce elementary learners of an urban school to the research of a scientist working at a local university. The play was written in a way that might increase student understandings of the nature of science, scientific inquiry, the identity of scientists, and the work that scientists do. We collected pre-and post-play questionnaire responses and drawings of scientists from third and fourth grade students who attended (...) the play. We also interviewed five of the ten teachers whose students attended the play. Findings indicated that most of these teachers felt strongly that their students had learned about scientific inquiry, the identity of scientists, and the work that scientists do as a result of attending the play. However, less than half of the student questionnaires and drawings of scientists indicated such growth as a result of the play. That being said, numerous students were able to tell us what they learned from the play and many questionnaire responses and drawings indicated such learning. Implications for partnerships between schools and university faculty from various disciplines in order to develop potentially impactful plays that portray authentic scientific research are discussed.

This article presents an analysis of how scientists are portrayed in the Lebanese national science textbooks. The purpose of this study was twofold. First, to develop a comprehensive analytical framework that can serve as a tool to analyze the image of scientists portrayed in educational resources. Second, to analyze the image of scientists portrayed in the Lebanese national science textbooks that are used in Basic Education. An analytical framework, based on an extensive review of the relevant literature, was constructed that (...) served as a tool for analyzing the textbooks. Based on evidence-based stereotypes, the framework focused on the individual and work-related characteristics of scientists. Fifteen science textbooks were analyzed using both quantitative and qualitative measures. Our analysis of the textbooks showed the presence of a number of stereotypical images. The scientists are predominantly white males of European descent. Non-Western scientists, including Lebanese and/or Arab scientists are mostly absent in the textbooks. In addition, the scientists are portrayed as rational individuals who work alone, who conduct experiments in their labs by following the scientific method, and by operating within Eurocentric paradigms. External factors do not influence their work. They are engaged in an enterprise which is objective, which aims for discovering the truth out there, and which involves dealing with direct evidence. Implications for science education are discussed. (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)

Science lessons using inquiry only or history of science with inquiry were used for explicit reflective nature of science instruction for second-, third-, and fourth-grade students randomly assigned to receive one of the treatments. Students in both groups improved in their understanding of creative NOS, tentative NOS, empirical NOS, and subjective NOS as measured using VNOS-D as pre- and post-test surveys. Social and cultural context of science was not accessible for the students. Students in second, third, and fourth grades were (...) able to attain adequate views of empirical NOS, the role of observation and inference, creative and imaginative NOS, and subjective NOS. Students were not able to express adequate views of socially and culturally embedded NOS. Most gains in NOS eroded by the next school year, except for tentative NOS for both groups and creative NOS for the inquiry group. (shrink)

This paper discusses essential elements of the philosophical works of Ludwik Fleck and their potential interpretation for the teaching and learning of science. In the early twentieth century, Fleck made substantial contributions to understanding the sociological character of the nature of science and explaining the embedding of science in society. His works have several parallels to the later and very popular work, The Structure of Scientific Revolutions, by Thomas S. Kuhn, although Kuhn only indirectly referred to the influence of Fleck (...) on his own theories. Starting from a short review of the life of Ludwik Fleck, his philosophical work and its connections to Kuhn, this paper elaborates upon and illustrates how his theories can be considered for science education in order to provide learners with a better understanding of the nature of scientific endeavor and the bi-directional science-to-society links.

E. J. Holmyard was a distinguished scholar and schoolmaster in England in the first half of the twentieth century. After graduating from Cambridge in both natural science and history, he quickly established a reputation for his research into the early history of chemistry, especially Islamic alchemy, and for his advocacy of a historical approach to the teaching of science. Both these interests found expression in his large number of school chemistry textbooks, many of which were highly successful and innovative publications, (...) placing chemistry in its wider historical and cultural contexts and offering insights into what today would be called ‘the nature of science’. This essay explores the historical method of science teaching with particular reference to Holmyard’s ideas and his authorship of textbooks and comments upon why the history of science has featured so prominently in the history of school science education.

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

Research on the nature of science and science education enjoys a longhistory, with its origins in Ernst Mach's work in the late nineteenthcentury and John Dewey's at the beginning of the twentieth century.As early as 1909 the Central Association for Science and MathematicsTeachers published an article – ‘A Consideration of the Principles thatShould Determine the Courses in Biology in Secondary Schools’ – inSchool Science and Mathematics that reflected foundational concernsabout science and how school curricula should be informed by them. Sincethen (...) a large body of literature has developed related to the teaching andlearning about nature of science – see, for example, the Lederman and Meichtry reviews cited below. As well there has been intensephilosophical, historical and philosophical debate about the nature of scienceitself, culminating in the much-publicised ‘Science Wars’ of recent time. Thereferences listed here primarily focus on the empirical research related to thenature of science as an educational goal; along with a few influential philosophicalworks by such authors as Kuhn, Popper, Laudan, Lakatos, and others. Whilenot exhaustive, the list should prove useful to educators, and scholars in otherfields, interested in the nature of science and how its understanding can berealised as a goal of science instruction. The authors welcome correspondenceregarding omissions from the list, and on-going additions that can be made to it. (shrink)

In 1675, Burchard de Volder became the first university physics professor to introduce the demonstration of experiments into his lectures and to create a special university classroom, The Leiden Physics Theatre, for this specific purpose. This is surprising for two reasons: first, early pre-Newtonian experiment is commonly associated with Italy and England, and second, de Volder is committed to Cartesian philosophy, including the view that knowledge gathered through the senses is subject to doubt, while that deducted from first principles is (...) certain. On the surface, it is curious that such a man would bring experiments to university physics. After all, in demonstrating experiments to his students, he was teaching them through their senses, not reason. However, if we consider the institutional context of de Volder’s teaching, we come to see de Volder’s Cartesian experimentalism as representative of a certain form of pre-Newtonian Dutch Cartesian science, as well as part of a larger tradition of teaching through observation at the University of Leiden. Considering de Volder’s institutional context will help us see that de Volder’s experimentalism was not in spite of his Cartesianism, but motivated by it. This paper will describe de Volder’s physics curriculum, the Theatre in which it was taught and how his work predates similar efforts in other European Universities. The second part will consider three aspects of the culture at the University of Leiden: a tradition of teaching through observation, a particular reception of Cartesianism, and an eclectic approach to the New Philosophy. The concluding portion shows how de Volder would have understood his enterprise in Cartesian terms. (shrink)

Science teaching always engages a philosophy of science. This article introduces a modern philosophy of science and indicates its implications for science education. The hermeneutic philosophy of science is the tradition of Kant, Heidegger, and Heelan. Essential to this tradition are two concepts of truth, truth as correspondence and truth as disclosure. It is these concepts that enable access to science in and of itself. Modern science forces aspects of reality to reveal themselves to human beings in events of disclosure. (...) The achievement of each event of disclosure requires the precise manipulation of equipment, which is an activity that depends on truth as correspondence. The implications of the hermeneutic philosophy of science for science education are profound. The article refers to Newton’s early work on optics to explore what the theory implies for teaching. Modern science—as the event of truth—is a relationship between an individual student, equipment, and reality. Science teachers provide for their students’ access to truth and they may show how their discipline holds a special relationship to reality. If the aim of science teaching is to enable students to disclose reality, the science curriculum will challenge some of the current practices of schooling. If teachers base science teaching upon the hermeneutic philosophy of science, science will assert itself as the intellectual discipline that derives from nature, and not from the inclinations of human beings. Science teachers teach nature’s own science. (shrink)

Although the goal of developing school students’ understanding of nature of science has long been advocated, there is still a lack of research that focuses on probing how science teachers, a kind of major stakeholder in NOS instruction, perceive the values of teaching NOS. Through semi-structured interviews, this study investigated the views of 15 Hong Kong in-service senior secondary science teachers about the values of teaching NOS. These values as perceived by the teachers fall into two types. The first type (...) is related to students’ learning of science in the classroom and involves: facilitating the study of subject knowledge, increasing the interest in learning science, supporting the conduct of scientific inquiry, meeting the needs of public examinations, and fulfilling the requirement of learning science. The second type goes beyond learning science and includes developing thinking skills, cultivating scientific ethics in students, and supporting the participation in public decisions on socioscientific issues. Although rich relationships were perceived by these teachers between NOS instruction and students’ learning of science, few values were stated from broad social and cultural perspectives. Suggestions are made about developing teachers’ views of the values of teaching NOS so as to influence their intention of teaching it. (shrink)

Contributing to the recent debate on whether or not explanations ought to be differentiated from arguments, this article argues that the distinction matters to science education. I articulate the distinction in terms of explanations and arguments having to meet different standards of adequacy. Standards of explanatory adequacy are important because they correspond to what counts as a good explanation in a science classroom, whereas a focus on evidence-based argumentation can obscure such standards of what makes an explanation explanatory. I provide (...) further reasons for the relevance of not conflating explanations with arguments (and having standards of explanatory adequacy in view). First, what guides the adoption of the particular standards of explanatory adequacy that are relevant in a scientific case is the explanatory aim pursued in this context. Apart from explanatory aims being an important aspect of the nature of science, including explanatory aims in classroom instruction also promotes students seeing explanations as more than facts, and engages them in developing explanations as responses to interesting explanatory problems. Second, it is of relevance to science curricula that science aims at intervening in natural processes, not only for technological applications, but also as part of experimental discovery. Not any argument enables intervention in nature, as successful intervention specifically presupposes causal explanations. Students can fruitfully explore in the classroom how an explanatory account suggests different options for intervention. (shrink)

In this article, from the characterization of technoscience of the English historian J. Pickstone and the recognition of the importance of models and modelling in research and teaching of chemistry, the term technochemistry is introduced as a way of chemical knowledge. With the above new possibilities, rethinking the chemistry curriculum is opened.

Although postmodernist thought has become prominent in some educational circles, its influence on science education has until recently been rather minor. This paper examines the proposal of Michalinos Zembylas, published earlier in this journal, that Lyotardian postmodernism should be applied to science educational reform in order to achieve the much sought after positive transformation. As a preliminary to this examination several critical points are raised about Lyotard's philosophy of education and philosophy of science which serve to challenge and undermine Zembylas’ (...) project. Subsequently, the three main theses of Lyotard that Zembylas considers beneficial and wishes to transpose onto science classrooms and pedagogy are scrutinized and found to be more of a hindrance than a help to curriculum reformers.

The complex societal challenges of the twenty-first Century require scientific researchers and academically educated professionals capable of conducting scientific research in complex problem contexts. Our central claim is that educational approaches inspired by a traditional empiricist epistemology insufficiently foster the required deep conceptual understanding and higher-order thinking skills necessary for epistemic tasks in scientific research. Conversely, we argue that constructivist epistemologies provide better guidance to educational approaches to promote research skills. We also argue that teachers adopting a constructivist learning theory (...) do not necessarily embrace a constructivist epistemology. On the contrary, in educational practice, novel educational approaches that adopt constructivist learning theories often maintain traditional empiricist epistemologies. Philosophers of science can help develop educational designs focused on learning to conduct scientific research, combining constructivist learning theory with constructivist epistemology. We illustrate this by an example from a bachelor’s program in Biomedical Engineering, where we introduce conceptual models and modeling as an alternative to the traditional focus on hypothesis testing in conducting scientific research. This educational approach includes the so-called B&K method for constructing scientific models to scaffold teaching and learning conceptual modeling. (shrink)

In science policy, it is generally acknowledged that science-based problem-solving requires interdisciplinary research. For example, policy makers invest in funding programs such as Horizon 2020 that aim to stimulate interdisciplinary research. Yet the epistemological processes that lead to effective interdisciplinary research are poorly understood. This article aims at an epistemology for interdisciplinary research, in particular, IDR for solving ‘real-world’ problems. Focus is on the question why researchers experience cognitive and epistemic difficulties in conducting IDR. Based on a study of educational (...) literature it is concluded that higher-education is missing clear ideas on the epistemology of IDR, and as a consequence, on how to teach it. It is conjectured that the lack of philosophical interest in the epistemology of IDR is due to a philosophical paradigm of science, which prevents recognizing severe epistemological challenges of IDR, both in the philosophy of science as well as in science education and research. The proposed alternative philosophical paradigm entails alternative philosophical presuppositions regarding aspects such as the aim of science, the character of knowledge, the epistemic and pragmatic criteria for accepting knowledge, and the role of technological instruments. This alternative philosophical paradigm assume the production of knowledge for epistemic functions as the aim of science, and interprets ‘knowledge’ as epistemic tools that must allow for conducting epistemic tasks by epistemic agents, rather than interpreting knowledge as representations that objectively represent aspects of the world independent of the way in which it was constructed. The engineering paradigm of science involves that knowledge is indelibly shaped by how it is constructed. Additionally, the way in which scientific disciplines construct knowledge is guided by the specificities of the discipline, which can be analyzed in terms of disciplinary perspectives. This implies that knowledge and the epistemic uses of knowledge cannot be understood without at least some understanding of how the knowledge is constructed. Accordingly, scientific researchers need so-called metacognitive scaffolds to assist in analyzing and reconstructing how ‘knowledge’ is constructed and how different disciplines do this differently. In an engineering paradigm of science, these metacognitive scaffolds can also be interpreted as epistemic tools, but in this case as tools that guide, enable and constrain analyzing and articulating how knowledge is produced. In interdisciplinary research, metacognitive scaffolds assist interdisciplinary communication aiming to analyze and articulate how the discipline constructs knowledge. (shrink)

This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology (...) has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals. (shrink)

The inclusion of engineering standards in US science education standards is potentially important because of how limited engineering education for K-12 learners is, despite the ubiquity of engineering in students’ lives. However, the majority of learners experience science education throughout their compulsory schooling. If improved engineering literacy is to be achieved, then its inclusion in science curricula is perhaps the most efficient means. One significant challenge that arises, however, is in the framing of engineering relative to science by both teachers (...) and curriculum. Science and engineering are both distinct and interdependent. The nature of the contributions of science and engineering to one another has been an area of some examination in philosophy of technology and engineering, but little framing of this relationship has been conducted with K-12 science and engineering education contexts in mind. Nature of science is a critical layer of scientific understanding that has been used to explicitly support literacy in K-16 science classrooms for decades. However, engineering cannot be authentically and appropriately supported by NOS framing. There is an immediate need for discourse on the nature of engineering knowledge but not in isolation of NOS. Given the increasing inclusion of engineering in science classrooms, relationships between NOS and NOEK are in need of explication and argument. Our purpose is to promote a discussion about NOS, engineering, and the relationship between them without misrepresenting engineering as a subdomain of science or as an oversimplification of itself.

Particular social aspects of the nature of science, such as economics of, and entrepreneurship in science, are understudied in science education research. It is not surprising then that the practical applications, such as lesson resources and teaching materials, are scarce. The key aims of this article are to synthesize perspectives from the literature on economics of science, entrepreneurship, NOS, and science education in order to have a better understanding of how science works in society and illustrate how such a synthesis (...) can be incorporated in the practice of science education. The main objectives of this article are to argue for the role and inclusion of EOS and entrepreneurship in NOS and re-define entrepreneurship in the NOS context; explore the issues emerging in the “financial systems” of the Family Resemblance Approach to NOS and propose the inclusion of contemporary aspects of science, such as EOS and entrepreneurship, into NOS; conceptualize NOS, EOS, and entrepreneurship in a conceptual framework to explain how science works in the society; and transform the theoretical knowledge of how science operates in society into practical applications for science teaching and learning. The conceptual framework that we propose illustrates the links between State, Academia, Market and Industry. We suggest practical lesson activities to clarify how the theoretical discussions on the SAMI cycle framework can be useful and relevant for classroom practice. In this article, science refers to physics, chemistry, and biology. However, we also recommend an application of this framework to other sciences to reveal their social-institutional side. (shrink)

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 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)

Seventy-two Internet documents promoting creationism, intelligent design, or evolution were selected for analysis. The primary goal of each of the 72 documents was to present arguments for creationism, I.D., or evolution. We first identified all arguments in these documents. Each argument was then coded in terms of both argument type and argument topic. We then provided a quantitative summary of each argument type and topic for each of the three positions. Three clear patterns were revealed by the data. First, websites (...) promoting evolution were characterized by a narrow focus on appeals to empirical evidence, whereas websites promoting creationism and I.D. were quite heterogeneous in regards to argument type. Second, websites promoting evolution relied primarily on a small number of empirical examples, while websites promoting creationism and I.D. used a far greater range of arguments. Finally, websites promoting evolution were narrowly focused on the topic of descent with modification. In contrast, websites promoting creationism tackled a broad range of topics, while websites promoting I.D. were narrowly focused on the issue of the existence of God. The current study provides a quantitative summary of a systematic content analysis of argument type and topic across a large number of frequently accessed websites dealing with origins. The analysis we have used may prove fruitful in identifying and understanding argumentation trends in scientific writing and pseudo-scientific writing. (shrink)

Historical case studies of scientific concepts are a useful medium for showing how scientific ideas originate and how they change over time. They are thus a useful tool for conveying knowledge about the nature of science. This paper focuses on the concepts of heat and temperature and discusses some issues related to choosing the content for a historical case study which incorporates not only nature of science perspectives but understandings related to what we know about the teaching and learning of (...) these concepts. The case study is designed for first-year university chemistry students as an introduction to their study of thermodynamics. The paper includes a general chemistry textbook analysis of the heat and temperature concepts and a discussion of the caloric theory of heat, thermometry, and a brief survey of how the energy concept transformed our understanding of heat and temperature.

This chapter presents the historical-investigative approach used in science teaching. Both history and philosophy of science have come to a sophisticated understanding of the role that experiments play in the generation and establishment of scientific knowledge. This recent development, called the “experimental turn,” is discussed first. Next, this chapter analyzes how practical work has been discussed among science educators in recent decades. Based on such a broad perspective, the historical-investigative approach is linked to recent advancements in history and philosophy of (...) science and in science education. Several modifications of the historical-investigative approach are outlined in order to illustrate their particular objectives, potential, and richness. (shrink)

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.
