核心素养视角下“分子和原子”的教学实践与反思

Teaching Practice and Reflection on “Molecular and Atomic” from the Perspective of Core Literacy

通过对"分子和原子"教学实践的观察和分析,探讨了核心素养视角下化学概念教学的方法和策略。讨论认为,化学概念的诠释与演绎要基于学生的认知能力,要遵循"抽象→具象→抽象"的建构历程,而多维、深刻的参与性则有助于概念的高质量建构。

Through the observation and analysis of the teaching practice of "molecule and Atom", the methods and strategies of chemistry concept teaching under the perspective of core literacy are discussed. The discussion holds that the interpretation and interpretation of chemical concepts should be based on students’ cognitive ability, and should follow the construction process of "abstract → concrete → abstract", while multidimensional and profound participation is conducive to the high-quality construction of concepts.
