Given the diversity of materials in our surroundings, one should expect scientifically literate citizens to have a basic understanding of the core ideas and practices used to analyze chemical substances. In this article, we use the term ‘chemical identity' to encapsulate the assumptions, knowledge, and practices upon which chemical analysis relies. We conceive chemical identity as a core crosscutting disciplinary concept which can bring coherence and relevance to chemistry curricula at all educational levels, primary through tertiary. Although chemical identity is not a concept explicitly addressed by traditional chemistry curricula, its understanding can be expected to evolve as students are asked to recognize different types of substances and explore their properties. The goal of this contribution is to characterize students' assumptions about factors that determine chemical identity and to map how core assumptions change with training in the discipline. Our work is based on the review and critical analysis of existing research findings on students' alternative conceptions in chemistry education, and historical and philosophical analyses of chemistry. From this perspective, our analysis contributes to the growing body of research in the area of learning progressions. In particular, it reveals areas in which our understanding of students' ideas about chemical identity is quite robust, but also highlights the existence of major knowledge gaps that should be filled in to better foster student understanding. We provide suggestions in this area and discuss implications for the teaching of chemistry. 相似文献

Understanding the nature of chemical thinking and action, as well as their application and impact on our world should be central goals of chemistry education at all educational levels. However, traditional school chemistry is still mostly focused on having students learn the body of declarative knowledge built over the years in the discipline. Achieving changes in curriculum and teaching practices in this context remains a challenging task. Studies in the history and philosophy of the discipline suggest that chemistry has unique characteristics that need to be recognised and considered in chemistry education. Many of these studies point to a pluralism in the discipline, and in the understanding of and about chemistry, that should be characterised and incorporated into our educational models. In this essay, we have attempted to build such a characterisation using conceptual profiles theory to propose a framework that can be used to enrich and support the thinking and action of chemistry teachers at all educational levels. 相似文献

For more than 40 years, the international community has acknowledged the role education might play in environmental awareness and conservation. The last major initiative came when the United Nations General Assembly proclaimed a Decade of Education for Sustainable Development (2005–2014). In the final year of the decade, teachers still struggle to realise education for sustainable development (ESD). One of the challenges teachers face with respect to ESD is the inclusion of even more content into an already overloaded curriculum. In response, it has been suggested that ESD should be introduced as an integrated perspective across the content of all existing subjects. This paper offers a model for how ESD can be realised in chemistry education. The model has been developed to support chemistry teachers in their educational planning and consists of 5 categories: chemical content knowledge, chemistry in context, the distinctiveness and methodological character of chemistry, ESD competences and lived ESD. The ESD model is illustrated through 5 ellipses, visualising the hierarchy of the categories, as they exist in different levels. All 5 ESD categories need to be considered in a holistic ESD approach. 相似文献

化学学科理解是一种学习活动,其主体是高中化学教师,其功能是使教师丰富化学学科教学知识、完善化学学科教学思维、提升化学教学能力,为落实“素养为本”的教学目标做好理解方面的准备。教师应从以下三个方向来增进化学学科理解:既要关注知识的成立条件,又要关注知识的依存条件;既要基于知识内在结构进行完整性理解,又要基于知识结构化进行关联性理解;既要关注知识的科学属性,又要关注知识的实践属性、辩证属性等其他属性。 相似文献

Volunteer non-major chemistry students taking an introductory university chemistry course (n = 17) were interviewed about their understanding of a variety of chemical diagrams. All the students’ interviewed appreciated
that diagrams of laboratory equipment were useful to show how to set up laboratory equipment. However students’ ability to
explain specific diagrams at either the macroscopic or sub-microscopic level varied greatly. The results highlighted the poor
level of understanding that some students had even after completing both exercises and experiments using the diagrams. The
connection between the diagrams of the macroscopic level (equipment, chemicals), the sub-microscopic level (molecular) and
the symbolic level (equations) was not always considered explicitly by students. The results indicate a need for chemical
diagrams to be used carefully and more explicitly to ensure learner understanding. Correspondingly, students need to interpret
visual chemical diagrams using meta-visualization skills linking the various levels of representation, and appreciating the
role of the diagrams in explanations need to be developed. 相似文献
