随着新课程改革的深入,化学课堂需要留给学生更多时间,让学生自主学习、合作学习、探究学习,因此课堂精讲点拨环节中的教学设计和策略就更为重要。学生对容易混淆的知识、重难点知识、需要深化理解和变式理解的知识,以及关于科学方法、学习策略的知识,需要教师简明扼要的课堂精讲来帮助学生科学理解、形成科学方法和学习策略。本文基于认知负荷理论探讨一下化学课堂精讲教学。
With the deepening of the new curriculum reform, the chemistry class needs to allow more time for students to learn independently, learn cooperatively and explore learning. Therefore, it is even more important that the teaching design and strategy in the intensive teaching of the class be emphasized. Students need to be confused with knowledge, heavy and difficult knowledge, knowledge that requires deeper understanding and variant understanding, and knowledge of scientific methods and learning strategies, requiring teachers to concise and succinct lectures in class to help students understand science and form scientific methods and learning Strategy. In this paper, based on the theory of cognitive load to explore the chemistry class teaching.
