指向核心素养的高中化学单元教学设计与实践——以沪科版新教材必修一“原子结构”为例

Unit Teaching Design and Practice Pointing to the Core literacy-A Case Study on Atomic Structure of Shanghai Senior School New Textbooks

基于学科核心素养进行单元教学,对推动课堂教学转型、落实新课程理念具有重要意义。文章以沪科版高中化学新教材必修一“原子结构”为例,实施指向“证据推理与模型认知”核心素养的单元教学。通过分析新教材相关内容的编排特点与承载的素养发展功能,规划单元课时,确定单元教学目标,设计单元教学活动,精选案例进行教学实践,并进行评估反思,提出培养证据推理意识、发展逻辑推理能力的教学策略。

Unit teaching based on subject core literacy is of great significance to promote the transformation of classroom teaching and implement the new curriculum concept.This paper has taken“atomic structure”as an example,which is a part in one of the new textbooks of chemistry for high schools,published by Shanghai Science and Technology Press,and tried to imple‐ment the core literacy of“evidential reasoning and model cognition”in unit teaching.After the analysis of the characteristics of relevant content arrangement in the new textbooks and the function of literacy development contained,teachers can well plan unit class hours,determine unit teaching objectives,design unit teaching activities,select the cases for teaching practice,evaluation and reflection,and put forward the teaching strategies to cultivate the awareness of evidential reasoning and develop the compe‐tence for logical reasoning.
