情境的创设源于教学的需要,但又不同于教材的内容,其创设的核心作用是激发学生的情感.化学课堂教学中教师应根据学生已有的认知结构和思维层次,适时提出学生熟知但又一时解释不了的问题,造成学生认知冲突.这样就能创造直观而富有趣味的情境,从而激发学生思维和情感,使之进入特定的学习状态.以促进知识的主动建构以及知识、技能和体验的连接,提高课堂教学效率.下面以初三化学为例,谈一谈课堂教学中学习情境的创设
The creation of situation stems from the need of teaching, but it is different from the content of teaching materials, and its core role is to stimulate students ’emotions.Teaching in chemistry classroom should be based on students’ existing cognitive structure and thinking level, But for a time can not explain the problem, resulting in cognitive conflict students.This will create an intuitive and interesting context, thus stimulating students thinking and emotion, to enter a particular state of learning to promote the active construction of knowledge and knowledge, skills And experience the connection to improve the efficiency of classroom teaching below to chemistry, for example, to talk about the creation of learning situations in classroom teaching
