Practicing scientists’ views of science recently have become a topic of interest to nature of science researchers. Using an interview protocol developed by Carey and Smith that assumes respondents’ views cohere into a single belief system, we asked 15 research chemists to discuss their views of theories and experimentation. Respondents expressed a range of ideas about science during interviews, but in ways that defied assignment to a unitary, coherent belief system. Instead, scientists expressed more or less constructivist ideas depending upon (...) the questions asked. We interpret our findings to suggest that efforts to categorize such conceptions at best oversimplify, and at worst misconstrue, people’s views about science and how such ideas might develop.

Efforts to assess students' and teachers' understandings of nature of science have extended for over 50 years. During this time, numerous instruments have been developed that span the full range of assessments from the traditional to open-ended assessments with interviews. As one might expect, the development, use, and interpretation of these assessments have paralleled the scholarship on students’ and teachers’ understandings of nature of science. Consequently, such assessments have evidenced the same challenges and obstacles seen in the general research literature. (...) This chapter will provide a rationale for the importance of teaching, and assessing, nature of science as well as a discussion of the construct. A comprehensive review and a critical analysis of the various assessments are also provided. Finally, an in-depth discussion of the contemporary issues regarding nature of science and its assessment is provided along with cautions regarding the future direction of nature of science assessment.

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.

In french and english speaking countries, the articulation between epistemological beliefs, conceptions of teaching and learning and pedagogical practices of secondary school teachers in the natural sciences and humanities has been little studied (Araújo-Oliveira, 2012 ; Bartos et Lederman, 2014 ; Wanlin et al., 2019). Yet, while teachers display predominantly constructivist beliefs about teaching and learning, their teaching practices remain rather passive (OECD, 2019). Like in Therriault et al. (2018-2023), this article explores the characteristics of epistemological beliefs, conceptions of teaching (...) and learning, and teaching practices among a population of 112 secondary school teachers (beginners, intermediate and experienced) in the humanities and natural sciences in French-speaking Belgium. In a second step, we explore the articulations between these three theoretical constructs either from statistical analyses or from a more interpretative perspective. Quantitative analysis of the data (PCA, factorial ANOVA, correlations and Chi-square) show that teachers’ epistemological beliefs are rather refined, that there is an effect of professional seniority on these beliefs and that there is a link between refined epistemological beliefs and traditional conceptions of teaching and learning. Finally, teachers’ self-reported practices appear to be insensitive to the discipline being taught. (shrink)

The articulation between epistemological beliefs, conceptions of teaching and learning, and teaching practices of secondary school science and humanities teachers has been little studied, particularly in the francophone world (Araújo-Oliveira, 2012, 2019 ; Bartos & Lederman, 2 014 ; Wanlin et al., 2019). Yet, while teachers display predominantly constructivist beliefs about teaching and learning, their actual teaching practices remain rather passive (TALIS international survey - OECD, 2019). After characterizing these three theoretical constructs in a sample of 215 Quebec secondary school (...) teachers (beginners, intermediate and experienced) in the humanities and social sciences and natural sciences, the article explores their articulations either through statistical analysis or by putting them into perspective in an interpretative phase of the research. The results are based on the quantitative analysis of teachers’ responses to a three-part closed online questionnaire. Statistical analyses (PCA, factorial ANOVA, correlations and Chi-square tests) show that teachers’ epistemological beliefs are rather refined, that there is an effect of seniority in the profession and an effect of the discipline taught on these beliefs, as well as a link between refined epistemological beliefs and traditional conceptions of teaching and learning. Finally, teachers’ self-reported practices appear to be insensitive to the discipline being taught. (shrink)

At Symposium No. 14, which took place as part of the 7th International Symposium on Education, a round table discussion was held with five speakers from the field of education at different levels of teaching. This round table was an opportunity to discuss the issues associated with the link between beliefs and pedagogical practices among teachers at different levels of teaching, as identified by the various papers, and to review experiences or training systems implemented to help support teachers in this (...) regard. The participants shared their experience of accompaniment future and beginning teachers, highlighting the discomforts felt by future and beginning teachers that corresponds to elements often raised in the literature. There were also processes put in place, depending on the different situations, to promote professional integration and integration into a school team, both through co-development processes and group or individual reflections on the knowledge and conceptions of these teachers who were coached. The analysis of their professional practice is a focal point reported by all the participants. (shrink)

This article presents the foundation of research around which other contributions in this issue are structured. It follows from a larger study aimed at supporting the professional development of beginning teachers with respect to their personal epistemology. The study explores the link between beliefs and practices in continuing education.It is an avenue that is still little used in research, particularly in Quebec, where research has focused more often on pre-service teachers. Previous studies identified highlight inconsistencies between expressed beliefs (epistemological and (...) pedagogical) and actual teaching practices. These concepts that are central to our approach. They will be clarified and illustrated in this article with the help of portraits of two high school natural science (NS) teachers offering a particular look at the tensions present in the belief-practice articulations. These two portraits are elaborated mostly from qualitative data drawn from explanatory interviews, from which similarities and dissimilarities emerge with regard to the question studied. The article conclude with suggestions for accompanying beginning teachers in resolving these tensions. (shrink)

Explaining phenomena is a primary goal of science. Consequently, it is unsurprising that gaining a proper understanding of the nature of explanation is an important goal of science education. In order to properly understand explanation, however, it is not enough to simply consider theories of the nature of explanation. Properly understanding explanation requires grasping the relation between explanation and understanding, as well as how explanations can lead to scientific knowledge. This article examines the nature of explanation, its relation to understanding, (...) and how explanations are used to generate scientific knowledge via inferences to the best explanation. Studying these features and applications of explanation not only provides insight into a concept that is important for science education in its own right, but also sheds light on an aspect of recent debates concerning the so-called consensus view of nature of science (NOS). Once the relation between explanation, understanding, and knowledge is clear, it becomes apparent that science is unified in important ways. Seeing this unification provides some support for thinking that there are general features of NOS of the sort proposed by the consensus view and that teaching about these general features of NOS should be a goal of science education. (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 idea of family resemblance, when applied to science, can provide a powerful account of the nature of science (NOS). In this chapter we develop such an account by taking into consideration the consensus on NOS that emerged in the science education literature in the last decade or so. According to the family resemblance approach, the nature of science can be systematically and comprehensively characterised in terms of a number of science categories which exhibit strong similarities and overlaps amongst diverse (...) scientific disciplines. We then discuss the virtues of this approach and make some suggestions as to how one can go about teaching it in the classroom. (shrink)

The rich and ongoing debate about constructivism in chemistry education includes questions about the relationship, for better or worse, between applications of the theory in pedagogy and in epistemology. This paper presents an examination of the potential to use connections of epistemological and pedagogical constructivism to one another. It examines connections linked to the content, processes, and premises of science with a goal of prompting further research in these areas.

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)

In light of recent emphasis on K-12 scientific modeling, it is important to understand how students’ models and beliefs about modeling shape shared classroom practices, and how, in turn, shared classroom practices influence individual students’ practices. We use co-operative action to consider the ways in which sedimented practices and artifacts become part of the substrate for students’ later actions ). Lemke :273–290, 2000) and Goodwin describe and provide illustrative examples of the accumulative nature of transformation of materials and practices. However, (...) these examples range in scale from minutes to hours, and there is less guidance about applying these perspectives to consider the transformation of practices longitudinally. In this study, we find that co-operative action is a powerful framework for analyzing classroom practices. We show that new practices rippled through the classroom along three dimensions: immediate transformation, longitudinal reuse and transformation, and transformation through interaction with other practices. These findings confirm that students’ models and practices become part of the substrate for later enactments of practice, and that these practices develop co-operatively and accumulatively within the classroom. Thus, co-operative action provides a unique lens on student progress that complements learning progressions by considering the social dimension of the development of practices. We propose that the extent to which students’ practices are able to sediment into the substrate of shared classroom practices is an important indicator of the health of the classroom as a scientific community.

This case study explores students’ physics-related personal epistemologies in school science practices. The school science practices of nine eleventh grade students in a physics class were audio-taped over 6 weeks. The students were also interviewed to find out their ideas on the nature of scientific knowledge after each activity. Analysis of transcripts yielded several epistemological resources that students activated in their school science practice. The findings show that there is inconsistency between students’ definitions of scientific theories and their epistemological judgments. (...) Analysis revealed that students used several epistemological resources to decide on the accuracy of their data including accuracy via following the right procedure and accuracy via what the others find. Traditional, formulation-based, physics instruction might have led students to activate naive epistemological resources that prevent them to participate in the practice of science in ways that are more meaningful. Implications for future studies are presented. (shrink)

Mathematics is a critical part of much scientific research. Physics in particular weaves math extensively into its instruction beginning in high school. Despite much research on the learning of both physics and math, the problem of how to effectively include math in physics in a way that reaches most students remains unsolved. In this paper, we suggest that a fundamental issue has received insufficient exploration: the fact that in science, we don’t just use math, we make meaning with it in (...) a different way than mathematicians do. In this reflective essay, we explore math as a language and consider the language of math in physics through the lens of cognitive linguistics. We begin by offering a number of examples that show how the use of math in physics differs from the use of math as typically found in math classes. We then explore basic concepts in cognitive semantics to show how humans make meaning with language in general. The critical elements are the roles of embodied cognition and interpretation in context. Then, we show how a theoretical framework commonly used in physics education research, resources, is coherent with and extends the ideas of cognitive semantics by connecting embodiment to phenomenological primitives and contextual interpretation to the dynamics of meaning-making with conceptual resources, epistemological resources, and affect. We present these ideas with illustrative case studies of students working on physics problems with math and demonstrate the dynamical nature of student reasoning with math in physics. We conclude with some thoughts about the implications for instruction. (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)
