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)

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.

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers specializing in physics and chemistry. The approach was explicit and reflective. Three research questions were posed: What conceptions of NOS do the PSSTs show after a first reflective reading of the historical controversy?, What role is (...) played by the PSSTs’ whole class critical discussion of their first reflections on the aspects of NOS dealt with in the controversy?, and What changes are there in the PSSTs’ conceptions of NOS after concluding the activity? The data for analysis was extracted from the PSSTs’ group reports submitted at the end of the activity and the audio-recorded information from the whole class discussion. A rubric was prepared to assess this data by a process of inter-rater analysis. The results showed overall improvement in understanding the aspects of NOS involved, with there being a significant evolution in some cases and moderate in others. This reveals that the activity has an educational utility for the education of PSSTs in NOS issues. The article concludes with an indication of some educational implications of the experience.

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)

In the last decades, a great amount of research has advocated innovating science education through teaching contents of the history, sociology, and philosophy of science in order for the students to get a reliable image of science, significant and relevant learning experiences, and higher interest and engagement in science. Given the embeddedness of techno-scientific systems in contemporary societies, the science-technology-society (STS) movement suggested the simple initiative of teaching science through making explicit the interrelationships between science, scientists, technology, and society to (...) achieve these aims. Since then, the STS tradition has evolved and produced some conceptual variations. This paper deals with three of these variations that are currently the key areas of school science education research and teaching: “socio-scientific issues,” “scientific literacy for all,” and “nature of science.” As heirs of the STS tradition, these mottos embody, at the same time, a clear continuity with STS origins, and some discontinuities, which arise from the development of their own paradigms, adding original elements to the STS movement.

This article presents and discusses an innovative pedagogical device designed for training pre-service teachers on the nature of science. We endorse an approach according to which aspects of the nature of science should be explicitly discussed in order to be understood by learners. We identified quantum physics, and more precisely the principles of uncertainty and complementarity, as a rich topic suitable for such a discussion. Our training device consists in preparing and staging a new type of theater, the “scientific experimental (...) theater,” based both on the characteristics of Brecht’s theater and Kelly’ cyclic theory of learning. This device was implemented with a group of eight pre-service teachers. According to our observations, the approach favors their involvement and provides them with a frame for expressing their doubts and confronting their points of view. By analyzing their discussion, we identified several aspects of the nature of science that the pre-service teachers raised spontaneously: subjectivity, the social and cultural embeddedness of science, the construction and status of models, and the role of questioning in the development of science. The implemented device therefore appears as an interesting means for stimulating a rich discussion on the nature of science. This study opens new avenues for teachers’ and students’ training devices aimed at developing a critical and reflective stance on science. (shrink)

Philosophical debates on the nature and significance of values in scientific knowledge and practices have differentiated cognitive (or epistemic) values from noncognitive (non-epistemic, such as moral or political) ones. The significance of cognitive values has come to be more or less commonly accepted, but the place of noncognitive values is much more controversial. Analysis and debate on values-related dimensions of scientific knowledge and inquiry has been on the rise in contemporary philosophy of science since 1970. This chapter provides an overview (...) of some current philosophical work on the subject and its possible impact on school science education. -/- First, a sample of these philosophical stances is presented, with emphasis on three different authors who recognise the role of non-epistemic values in scientific activity, without necessarily relinquishing a place for objectivity. Then, some of the rationales for including teaching about values in science education are addressed. The science education and philosophy education research is deployed to sketch some issues that would have to be taken into consideration when introducing one particular type of values – ethics related issues – in the secondary education classroom. -/- Finally, the desirability of a greater interaction among science and philosophy educators is emphasised. Mutual knowledge of the convergences and divergences in approach to values in scientific knowledge and practices, and the challenges posed by teaching about them, can lead to richer and more nuanced approaches to the common aspects in their respective topics.
