The ubiquitous goals of helping precollege students develop informed conceptions of nature of science and experience inquiry learning environments that progressively approximate authentic scientific practice have been long-standing and central aims of science education reforms around the globe. However, the realization of these goals continues to elude the science education community partly because of a persistent, albeit not empirically supported, coupling of the two goals in the form of ‘teaching about NOS with inquiry’. In this context, the present paper aims, (...) first, to introduce the notions of, and articulate the distinction between, teaching with and about NOS, which will allow for the meaningful coupling of the two desired goals. Second, the paper aims to explicate science teachers’ knowledge domains requisite for effective teaching with and about NOS. The paper argues that research and development efforts dedicated to helping science teachers develop deep, robust, and integrated NOS understandings would have the dual benefits of not only enabling teachers to convey to students images of science and scientific practice that are commensurate with historical, philosophical, sociological, and psychological scholarship, but also to structure robust inquiry learning environments that approximate authentic scientific practice, and implement effective pedagogical approaches that share a lot of the characteristics of best science teaching practices.

Intersemiotic translation (IT) was defined by Roman Jakobson (The Translation Studies Reader, Routledge, London, p. 114, 2000) as “transmutation of signs”—“an interpretation of verbal signs by means of signs of nonverbal sign systems.” Despite its theoretical relevance, and in spite of the frequency in which it is practiced, the phenomenon remains virtually unexplored in terms of conceptual modeling, especially from a semiotic perspective. Our approach is based on two premises: (i) IT is fundamentally a semiotic operation process (semiosis) and (ii) (...) IT is a deeply iconic-dependent process. We exemplify our approach by means of literature to dance IT and we explore some implications for the development of a general model of IT. (shrink)

Sözde-bilim ile ilgili bu tartışmalar uluslararası literatürde yapılıyor olsa da Türkiye’de henüz bu konuların eleştirel olarak ele alındığı söylenemez. Dolayısıyla sözde-bilimlerin eleştirel olarak ele alındığı öğrenme ortamlarının öğrencilerin bilime ve sözde-bilime ilişkin algılarına etkisi üzerine yapılacak araştırmalar konunun daha iyi anlaşılmasını sağlayabilir ve belki de ilerideki program değişiklerinde öğretim programlarında sözde-bilimin yer bulmasının yolunu açabilir.

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)

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)

This paper aims at analysing the perception of agricultural sciences pre-service teachers regarding the relationship between didactic competencies and learning motivation. According to specialists, there are four components of didactic competence: scientific competence, psycho-social competence, managing competence and psycho-pedagogical competence. In our study, we primarily intend to determine the students’ perception concerning the impact of those four didactic competences over the learning motivation. Secondly, we aim at analysing the relationship between the competences students consider to be relevant for the learning (...) motivation and didactic competences they wish to acquire by the end of the psychopedagogical program. The study was accomplished during the university year 2014-2015 over a batch of 65 participants, students attending the second year of study at the Faculty of Agriculture. The collected data was obtained by the method of enquiry and using a questionnaire of opinion as a tool, which contained 24 closed, pre-coded questions. The obtained results have revealed that agricultural sciences pre-service teachers consider that among the didactic competences, the most powerful impact over learning motivation belongs to the psycho-pedagogical competence, followed by the scientific competence and the psychosocial competence. Also, the scores reflecting the importance of those competences regarding the motivational factor positively and significantly correlates with the scores reflecting the level at which students wish to develop those competences. These findings bring their contribution to getting a clearer image over the accomplishment of some success performances in training students for the didactic profession. (shrink)

Understanding Nature of Science is a central component of scientific literacy, which is agreed upon internationally, and consequently has been a major educational goal for many years all over the globe. In order to justify the promotion of an adequate understanding of NOS, educators have developed several arguments, among them the cultural argument. But what is behind this argument? In order to answer this question, C. P. Snow’s vision of two cultures was used as a starting point. In his famous (...) Rede Lecture from 1959, he complained about a wide gap between the arts and humanities on the one hand and sciences on the other hand. While the representatives of the humanities refer to themselves as real intellectuals, the scientists felt rather ignored as a culture, despite the fact that their achievements had been so important for Western society. Thus, Snow argued that as these intellectual cultures were completely different from each other, a mutual understanding was impossible. The first European Regional IHPST Conference took up the cultural view on science again. Thus, the topic of the conference “Science as Culture in the European Context” encouraged us to look at the two cultures and to figure out possibilities to bridge the gap between them in chemistry teacher education. For this reason, we put together three studies—one theoretical and two independent research projects which contribute to our main research field —in order to address the cultural argument for understanding science from an educational point of view. Among the consented tenets of what understanding NOS implies in an educational context, there are aspects which are associated mainly with the humanities, like the tentativeness of knowledge, creativity, and social tradition, whereas others seem to have a domain-specific meaning, like empirical evidence, theories and laws, and the role of technology. Thus, the cultural argument for understanding science invites us not only to consider domain-specific concepts but also to reflect on similarities between science and the humanities by way of examples.

Understanding the nature of science has long been a desired outcome of science education, despite ongoing disagreements about the content, structure, and focus of NOS expectations. Addressing the concern that teachers likely focus only on student learning expectations appearing in standards documents, this study examines the current state of NOS in science education standards documents from nine diverse countries to determine the overt NOS learning expectations that appeared, NOS statements provided near those learning expectations, but not identified as learning outcomes, (...) and NOS statements found in ancillary text. Findings indicate that NOS ideas rarely occur as expectations for student learning and are far more commonly found in ancillary material. Moreover, consensus was not apparent in the overt learning outcomes for students. Given the well-documented poor state of NOS instruction and the consistent lack of NOS appearing in published curriculum materials, the NOS standards appearing in nearly all documents analyzed are unlikely to provide sufficient conceptual or pedagogical support for NOS to be accurately interpreted or translated into meaningful experiences for students.

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)

The present study specifically focuses on science teachers’ views about scientific inquiry and their use of scientific inquiry in their lesson plans, which were prepared at a professional development workshop designed for better utilization of science centers (SCs). As an impact evaluation research, qualitative data was collected from 41 purposively selected volunteer science teachers. The project team provided the participants with intense instruction in inquiry, and fostered them to learn nature of science and nature of scientific inquiry explicitly. The participants (...) designed lesson plans that integrate school science curricula with exhibits at SCs before and after the workshop. An open-ended questionnaire about the views about scientific inquiry (VASI) was administered before and after the workshop, and teachers’ post-lesson plans were analyzed to detect the presence of scientific inquiry aspects. The majority of teachers exhibited improved views about scientific inquiry based on the VASI instrument. Also, lesson plan analyses indicated that teachers, who showed more improvement in VASI, included more scientific inquiry (SI) elements in their post-lesson plans. It was observed that science teachers’ lesson plans are limited in terms of teaching science in line with real scientific inquiries in SCs to make students learn about the nature of scientific inquiry while learning science. Only two groups embedded SI properly in the SC-oriented lesson plans, and teachers rather used inquiry-based methods of teaching (e.g., argumentation, predict-observe-explain) and process skills (e.g., questioning, explanations). Accordingly, further studies are suggested to develop a specific pedagogical content knowledge framework for teaching with/in SCs. (shrink)

This study explored changes in preservice teachers’ nature of science pedagogical views and nature of science rationales using pre- and post-course written responses as well as interview data. Through systematic analysis, themes were generated and compared to the NOS literature. Comparisons between pre- and post-course data demonstrate improved and deepened NOS views, NOSP views that are more aligned with NOS literature, and a greater number of rationales for including NOS. All participants were enrolled in the “Inquiry and Natures of Science, (...) Technology, and Engineering” course. However, six participants were enrolled in INSTE as their first course in which NOS and NOSP were addressed. The other six participants were enrolled in INSTE as their second course in which NOS and NOSP were addressed, with science methods as their first course in which NOS and NOSP were addressed. By comparing participants enrolled in INSTE as their first course to those enrolled in INSTE as their second course, we observed that NOS understanding seemed to develop in a first experience alongside some NOS rationales, but NOSP views lagged for participants in INSTE as their first course. Participants enrolled in INSTE as their second course developed more robust and literature-aligned NOSP views and more multifaceted NOS rationales. Therefore, this study bolsters arguments that teachers need to receive extended NOS and NOSP instruction. (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)

Scientific reasoning is particularly pertinent to science education since it is closely related to the content and methodologies of science and contributes to scientific literacy. Much of the research in science education investigates the appropriate framework and teaching methods and tools needed to promote students’ ability to reason and evaluate in a scientific way. This paper aims to contribute to an extended understanding of the nature and pedagogical importance of model-based reasoning and to exemplify how using computer simulations can support (...) students’ model-based reasoning. We provide first a background for both scientific reasoning and computer simulations, based on the relevant philosophical views and the related educational discussion. This background suggests that the model-based framework provides an epistemologically valid and pedagogically appropriate basis for teaching scientific reasoning and for helping students develop sounder reasoning and decision-taking abilities and explains how using computer simulations can foster these abilities. We then provide some examples illustrating the use of computer simulations to support model-based reasoning and evaluation activities in the classroom. The examples reflect the procedure and criteria for evaluating models in science and demonstrate the educational advantages of their application in classroom reasoning activities. (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.

Two fundamental questions about science are relevant for science educators: What is the nature of science? and what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach, originally developed by (...) Irzik and Nola in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere. The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.

This study investigates the use of specific educative features for supporting the teaching of nature of science during read-alouds of elementary science trade books. Educative features are components of educative curriculum materials that aim to increase teachers’ content knowledge and support effective instructional practices. Understanding how teachers use specific educative features is important for the future design of curriculum materials that can be used to improve teachers’ views of NOS in tandem with changing their teaching practices. Qualitative data from teacher (...) interviews and observations of read-alouds were used to determine which educative features teachers used and how effective they were perceived as being. Results indicate that teachers varied in their use of educative features and tended to focus on the ones that addressed specific teaching moves as opposed to those that supported understanding why the curriculum was developed as it was. Based on these findings, recommendations for future research that highlights the importance of all educative features are provided. (shrink)

The work of science is a linguistic act. However, like history and philosophy of science, language has frequently been isolated from science content due to factors such as school departmentalization and narrow definitions of what it means to teach, know, and do science. This conceptual article seeks to recognize and recognize—to understand and yet rethink—science content in light of the vision of science expected by academic standards. Achieving that vision requires new perspectives in science teaching and teacher education that look (...) into the role that science language expectations play in science content. These perspectives reposition attention to language from a hidden, overlooked, or outsourced aspect of science teaching, to one at its core. To help bring teachers and teacher educators into this integrative view of science content, this article offers a mirror, a prism, and a lens as three metaphorical tools to explore the essential roles that language plays for, in, and as science content. The reflection, refraction, and refocusing of science content reveal complex science language expectations that function alongside facts, figures, and formulas of science as gatekeeping mechanisms that, once noticed, cannot be ignored or marginalized in science teaching and science teacher 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.

The development of science curricula in both mainland China and Hong Kong in the last decade has undergone a shift from content-focused goals to a wider goal of promotion of scientific literacy. This shift is a result of a considerable influence from Western countries where understanding of nature of science (NOS) has long been regarded as a major component of scientific literacy and important learning outcomes of science curricula in the West. This chapter will first report on the similarities and (...) differences of the NOS ideas as portrayed in the physics curriculum standards document and the key physics textbooks in both places. The unique differences identified are associated strongly with certain social agenda and considerably influenced by the historical and cultural heritages of mainland China and Hong Kong. Lastly the considerable difference in the implementation of NOS education at teacher training level and school level in both places will be elaborated. (shrink)

This is a thesis which contributes to research in two different fields: theoretical physics and physics education research. The common link between these two research areas is that both involve explorations of abstract physics and mathematical representations, but from different perspectives. The first part of this thesis is situated in theoretical physics. Here a cosmological scenario is explored where a de Sitter phase is replaced with a phase described with a scale factor a ~ tq, where 1/3<1. This scenario could (...) be viewed as an inflationary toy model, and is shown to open up the possibility of an information paradox. This potential paradox is resolved even in the worst case scenario by showing that the time scales involved for such a paradox to occur is of the order of magnitude of the recurrence time for the de Sitter space. The second part of this thesis is situated in physics education research. A number of learning situations that are experienced as abstract by students are explored: probability in one dimensional quantum tunnelling; the mindsets that students adopt towards understanding physics equations used in typical teaching scenarios; and what students focus on when presented with physics equations. The results for the quantum scattering study are four phenomenographic categories of description, for the mind sets study, six epistemological components of mindsets and for the focus on physics equations study, three foci creating five levels of increasing complexity of ways of experiencing physics equations. Pedagogical implications of these results are discussed. (shrink)
