Science education researchers have long advocated the central role of the nature of science for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological issues associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. One particularly promising method for teaching NOS involves an explicit (...) and reflective approach using the history of science. The purpose of this study was to determine the influence of a historically based genetics unit on undergraduates’ understanding of NOS. The three-class unit developed for this study introduces students to Mendelian genetics using the story of Gregor Mendel’s work. NOS learning objectives were emphasized through discussion questions and investigations. The unit was administered to undergraduates in an introductory biology course for pre-service elementary teachers. The influence of the unit was determined by students’ responses to the SUSSI instrument, which was administered pre- and post-intervention. In addition, semi-structured interviews were conducted that focused on changes in students’ responses from pre- to post-test. Data collected indicated that students showed improved NOS understanding related to observations, inferences, and the influence of culture on science. (shrink)

This article presents a study aiming at assessing the efficacy of reading newspaper articles with scientific content in order to incorporate nature of science aspects in initial primary teacher education. To this aim, a short teaching intervention based on newspaper articles was planned and performed under regular class conditions. First, prospective teachers read two newspaper articles related to a recent and controversial scientific research report in the field of physics. Next, they responded reflectively in small groups to various questions related (...) to NOS aspects insinuated in the articles in order for researchers to diagnose their prior ideas about these. Each group then presented their responses in class, and a discussion among groups was encouraged in order to provide feedback. Based on this, the groups revised their initial responses. The evolution of the written responses of the groups was analyzed through an interpretive approach using the methods of inter-rater and intra-rater analysis and low-inference descriptors. The findings showed that these prospective teachers in general improved their NOS views. In the absence of further research, these first findings make evident the pedagogical potential of reading certain newspaper articles for learning about NOS under usual classroom conditions. Finally, some educational implications and perspectives derived from the study are discussed. (shrink)

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

This is an important book precisely because there is none other quite like it.

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

The first edition of this book profoundly challenged and divided students of philosophy, sociology, and the history of science when it was published in 1976. In this second edition, Bloor responds in a substantial new Afterword to the heated debates engendered by his book.

Thomas S. Kuhn's classic book is now available with a new index.

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.

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)

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.

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.
