This study explores book talks as an approach to teaching Nature of Science (NOS) to young children (4-6 years old). To teach about NOS means to, in one way or another, focus on the processes, humans that build science knowledge, as well as the characteristics and limits of scientific knowledge. Previous research in this area has studied the representation of NOS in science trade books and suggested ways for teachers to highlight this content, specifically in relation to books that have been rendered "exemplary" for teaching NOS. This study focuses on the actual conversations (i.e., book talks) between teachers and children related to science trade books that are available in bookstores. The aim of the study was to contribute further knowledge about the characteristics of book talks related to such books when they are used as an approach to teaching NOS. Book talks (N = 58) between two teachers and their respective groups of children were audiorecorded and transcribed. The results contribute by shedding light on how teachers use the book as a resource in combination with other resources to highlight various aspects of NOS during book talks. This is important since it shows how book talks as an approach to NOS teaching can be staged even if exemplary books are not available. A tentative model that can scaffold teachers' didactic analysis is presented.

The research field of science education has gathered questions about what science is, how scientific knowledge is developed and in what ways humans are involved in these processes under the umbrella concept 'nature of science' (NOS). Previous research has suggested that teaching ought to focus much more on these issues, but so far the focus has been on older children and students, while there is a lack of research on NOS teaching for the youngest children (up to six years). In this conceptual article, we suggest that NOS should be taught from the outset, and thus be part of science teaching in the early years. We put forward arguments as to "why" this early introduction coupled to the overall values and aims of democracy and social justice is important, and elaborate on the kind of NOS issues that could be included in science teaching aimed at the youngest children.

Nature of science (NOS) has increasingly been emphasized as an important element in science education. This paper engages in the question of how teachers negotiate different approaches to and contexts for NOS teaching. This exploratory study is part of a three-year longitudinal project where six in-service teachers developed and negotiated their NOS-teaching practices. Pickering's (1995) theory of "the mangle of practice" is used for the analysis of teachers' focus-group discussions. In a mangled practice, school science traditions, policy documents, and students' and teachers' expectations and identities are rubbed against each other. As part of the project teachers planned, implemented, and reflected on two NOS activities at different levels of contextualization. The concepts alignment, resistance, and accommodation are used as an analytical tool to understand the processes of the mangle in relation to teachers' negotiations concerning the two activities during the focus groups. The results of the mangle are presented in relation to a backdrop of three teaching traditions (facts, lab-work, and discussions) that the teachers' claim to depart from. The results show how the alignment and resistance of different components of the mangle lead to various accommodations as regards both the activities and the three traditions. The article concludes by discussing how the teachers' negotiations highlight what becomes possible and what becomes challenging when NOS meets existing traditions, and what this means in respect of possibilities for NOS learning.

This article focuses on the need for increased attention to content issues and working methods for science teaching in Early Childhood Education (ECE). Science education research emphasises the importance of not only focusing on specific phenomena, but also on the Nature of Science (NOS). NOS teaching deals with questions about what science is, how scientific knowledge is developed and in what ways humans are involved in these processes. An inclusion of such issues is important if common stereotypical images of science and scientists are to be challenged. Previous research has suggested that NOS can be taught through book talks connected to trade books. However, there is a lack of empirical studies at the ECE level supporting this suggestion. Thus, this article reports from the first part of a project in which researchers and teachers explored book talks as a possibility to introduce NOS in early years science (children between 1 and 5 years old). Data consists of book talks (N=48) around two picture trade books led by five preschool teachers preceded by a teacher-researcher workshop on NOS and NOS teaching. The results show that discussions on a variety of NOS issues is possible in an ECE context. These results are discussed in relation to previous literature on both NOS teaching and science in the early years.

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 (NOS) as a way to accomplish a more nuanced science teaching in Swedish compulsory school. The teachers (N = 6) 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 (a) the number of suggested issues increased over the years, (b) teachers' ways of contextualizing the issues changed from general and unprecise to more tightly connected to socio-scientific or scientific contexts, and (c) 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.

In the science education research field there is a large body of literature on the "nature of science" (NOS). NOS captures issues about what characterizes the research process as well as the scientific knowledge. Here we, in line with a broad body of literature, use a wide definition of NOS including also e.g. socio-cultural aspects. It is argued that NOS issues, for a number of reasons, should be included in the teaching of science/physics. Research shows that NOS should be taught explicitly. There are plenty of suggestions on specific and separate NOS activities, but the necessity of discussing NOS issues in connection to specific science/physics content and to laboratory work, is also highlighted. In this article we draw on this body of literature on NOS and science teaching, and discuss how classroom situations in secondary physics classes could be turned into NOS-learning situations. The discussed situations have been suggested by secondary teachers, during in-service teacher training, as situations from every-day physics teaching, from which NOS could be highlighted.
