Since at least the eighteenth century scientific knowledge (then natural philosophy) was produced in groups of experts and specialists and was transmitted in schools, where, future experts and specialists were trained. The design of teaching has always been a complex process particularly in recent years when educational aims (for example, teaching scientific competence to everyone, not just to experts and specialists) present significant challenges. These challenges are much more than a simple reorganisation of the scientific knowledge pre-determined by the existing teaching tradition for different educational level. In the context of chemical education, the new teaching approaches should bring about not only the transmission of chemical knowledge but also a genuine chemical activity so as to ensure that students can acquire chemical thinking. Chemistry teaching should be revised according to contemporary demands of schooling. In order to move forward towards new teaching proposals, we must identify the genuine questions that generate ‘chemical criteria’ and we should focus on them for teaching. We think that a good strategy is to look for those criteria in the philosophy and history of chemistry, from the perspective of didactics of science. This paper will examine the following questions: (1) How can school science be designed as a world-modelling activity by drawing on the philosophy of science. (2) How can ‘stories’ about the emergence of chemical entities be identified by looking at the history of chemistry? (3) How can modelling strategies be structured in school chemistry activities? 相似文献

In this paper we discuss the foundations and process of design of a research-informed instructional unit aimed for pre-service
science teacher education. The unit covers some key ideas on the nature of science (around methodology, theory change, scientific
inference and explanation, values, gender issues) anchoring them in a well-known episode from the history of science—the ‘discovery’
of radium by the Curies. Such episode is mainly examined as reconstructed in the 1997 French commercial film ‘Les Palmes de
Monsieur Schutz’. Pre-service science teachers are required to solve three tasks, individually and in small groups; those
tasks are respectively centred around: (1) the distinction between ‘discovering’ and ‘inventing’; (2) scientific modelling
via abduction; and (3) the extended hagiographic treatment of the figure of Madame Curie. Plenary debates around the tasks
aim at acquainting pre-service science teachers with some powerful concepts of twentieth century philosophy of science. 相似文献

Based on a synthesis of contributions from differentauthors, we present a theoreticalframework that provides some foundations for schoolscience, and we define someresearch problems. We start from what is already knownabout students' models andcognition in order to construct proposals of didacticalintervention. The cognitive modelof science, developed in the philosophy of science throughstudying scientists' activity,has allowed us to propose an analogous model for schoolscience in which experimentationand language play the key roles. We emphasise the relativeindependence of school scienceand scientists' science. 相似文献
