课堂导入是调整课堂结构的一种重要方式,是活跃课堂氛围的一种至关要素。在高中化学课堂教学中,教师要注重课堂导入方式的多样性与实际性,要以化学知识的关联性与形象性推进课堂教学活动进入高潮阶段。 The introduction of the classroom is an important way to adjust the classroom structure and is an essential element of the active classroom atmosphere. In high school chemistry classroom teaching, teachers should pay attention to the diversity and actuality of classroom introduction, and should reach the climax stage with the relevance and visualization of chemistry knowledge to promote classroom teaching activities.
