化学观念的建构有利于激发学生持久的学习兴趣,帮助学生深入理解知识的内涵,从而有效促进化学核心素养的全面提高。传统的化学教学尤为注重元素及化合物的性质等事实性知识的记忆,而忽略更具重要价值的思维方法的提升和观念渗透等方面的问题。通过问题链的驱动,帮助学生学会知识网络的建构,建立元素观、转化观等化学观念,从而提升化学学科核心素养。
The construction of chemistry concept helps to stimulate students’ long-term interest in learning and help students to understand the connotation of knowledge so as to effectively promote the improvement of chemistry core literacy. The traditional chemistry teaching pays special attention to the memory of factual knowledge such as the nature of the elements and compounds, while neglecting the promotion of the thinking methods of more important value and the infiltration of concepts. Driven by the problem chain, it helps students to learn the construction of knowledge networks, establish chemical concepts such as the concept of elements and transformation, and enhance their core literacy in chemistry.
