“显性-反思性”的科学本质教学——以“原子结构”发展史为例

Using “Explicit-Reflective” Approach to Teach Nature of Science: A Case Study on the History of Atom Structure

科学本质作为国际科学教育的重要目标,受到越来越多的关注。但在实践中,教师缺少对科学本质的内涵和具体方面的深度理解,同时缺少有效的科学本质教学的相关指导。本文探讨了基础教育阶段科学本质的8个方面的具体内涵,阐明了科学本质的有效教学的特征,并以"原子结构"为例,为教师开展科学本质教学提供范例。

Nature of science(NOS) is an important objective for international science education, and it has attracted more and more attention. In teaching practice, however, teachers have not attained informed views of nature of science(NOS), and do not have the supports of NOS teaching. This study has discussed the contents of NOS for K-12 students and explained the characters of effective nature of science instruction. Using "the history of atom structure", the purpose of this study is providing examples of effective nature of science instruction to teachers.
