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 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)

The purpose of this thesis was set against the background of changed expectations on education and teachers’ work in contemporary Western societies, reflecting global educational trends of standardisation and assessment moving further down the ages. The overall aim of the thesis was to explore and gain understandings of how teachers’ work is constituted. The exploration was based on lived experience and philosophical perspectives, and the main research questions were: i) what is the significance of existential dimensions of teachers’ work, and (...) ii) how can they be understood in the light of a globalised and standardised education? The theoretical and methodological basis of the thesis was mainly the philosophy of the life-world as formulated by Maurice Merleau-Ponty. The studies included employed the following methods: drawings with associated oral comments, written teacher responses and follow-up interviews, visual documentation with associated oral comments, and finally, the study of the relevant philosophical literature. In total 50 teachers and 112 children participated in study I, ten teachers in study II and eight teachers in study III. In study IV, the data consisted of philosophical literature.The findings show that teachers’ work involves not only teachers’ intellectual capacities and skills, but also their emotional and embodied being, and intertwined relationships as well. Further, teachers’ work it affected not only by the views of children, knowledge and learning held by teachers, policymakers and society that affect teachers’ work, but also by ontological assumptions and existential dimensions in a wider sense. It emerged that teachers’ views of education and their attempt to appreciate the unpredictable beyond dualistic assumptions are holistic, and multidimensional, in comparison to the rather linear and standardised global agenda.The crossover analysis of the findings suggests that teachers’ work is mainly constituted by ambiguities and intertwinings of an ontological character that have epistemological implications. In this thesis ambiguities are used to describe aspects that at first seem contradictory but are in fact more like irreducible uncertainties – as intertwined and reversible aspects of teachers’ work as a whole. Accordingly, existential dimensions of teachers’ work are ubiquitous within these ambiguities and intertwinings, and appear as significant in mainly two ways – firstly, as closely connected dimensions of the life-world and lived experience, referred to as lived time, lived space, lived body and lived other; secondly, as basic notions mainly about the relationships between i) subject and object, ii) mind and body, iii) human, culture and nature, iv) linear and multidimensional temporality. These existential dimensions of teachers work are discussed as Intercorporeal reversibilities, Intertwinings, chiasm and flesh and A chiasmic being. The ambiguous aspects of teachers’ work seem to derive from a general ambiguity of views on education, in which the rationalistic view tends to dominate since it often reflects the management of education. This overall ambiguity demands a reconsideration of the wider aim of education as well as of different relationships within education beyond dualisms and divides. Particularly, intercorporeal and intertwined relationships are essential, encompassing the significant intertwinings of ‘subjectobject’, ‘mindbody’, and ‘humannatureculture’. It is argued that this rethinking needs to be done in order to create conceptual and operational space for diverse and challenging pedagogical relationships. Thereby, a process of a chiasmic being for teachers in their work and for children’s learning can be enhancedKey words: teachers’ work; teaching; school; early childhood education; lived experience; existential; pluralistic; Merleau-Ponty.

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)

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)
