高中化学课堂是教师引导和学生探究的主要场所,那么教学中如何才能让学生自由放飞思维的翅膀,同时教师又能在宏观层次施以恰当的引导,从而帮助学生提升化学学习的效率,全方位培养学生的核心素养呢?这就需要化学教师在实践中积极探索,恰当处理化学课堂上“收”与“放”的关系,并充分体现学生的主体地位。一、探索开放性的高中化学教学方式要放开对学生的束缚,教师首先要积极探索开放式 Chemistry classroom in high school is the main place for teachers to guide and explore students. How to make students free to fly their thinking wings in teaching, meanwhile teachers can guide them properly at the macro level to help students improve the efficiency of chemistry learning. It is necessary for chemistry teachers to actively explore in practice, appropriately handle the relationship between “receiving” and “letting” in chemistry class, and fully reflect the dominant position of students. First, explore the open high school chemistry teaching methods To release the constraints on students, teachers must first actively explore the open
