化学学科核心素养下的教学研究——以“氧化还原反应”为例

Research on teaching under the chemistry core literacy:a case study of the redox reaction

基于化学学科核心素养,以人教版高中化学必修一中的“氧化还原反应”知识为研究对象,探索如何在教学中发展学生的化学核心素养。本节内容主要从三个角度,即得失氧、化合价变化和得失电子的角度来展开设计,在“探究线”“知识线”“应用线”等三条认知线中发展学生的化学核心素养,使学生充分理解氧化还原反应概念。

Based on the core quality of chemistry,this paper,based on the“redox reaction”of the senior high school chemistry in high school,explores how to develop the students chemical core literacy.The content of this section is mainly from three angles,namely,the angle of gain and loss,valence change and gain and loss,and developing the chemistry core quality of the students in three cognitive lines,such as the“application line”,“knowledge line”and“exploratory line”,to deepen the students understanding of the concept of redox reaction.
