Abstract: With the concept of quality education put forward and deepened, the state began to pay more attention to the teaching quality of each training school age. Chemistry plays an important role in the study of senior high school. Therefore, high school chemistry teachers should base on the concept of quality education, innovate teaching methods, and constantly stimulate students' interest in learning. Only in this way can we improve classroom efficiency and deepen students' understanding of chemistry. Practice has proved that the problem situation creation method is loved by the majority of teachers in high school chemistry teaching, because the method can effectively arouse students' emotional resonance, and can lay a good foundation for the learning of new chemical knowledge. the paper elaborated the specific methods of creating problem situation in senior high school chemistry curriculum from different angles, hoping to provide powerful help for relevant teachers.

高中的化學科目属于一种实践性非常强的科目,因此也具有与生活紧密联系的特点。新课改提出之后,高中化学教师应当不断改变课堂教学模式,最大程度激发学生的学习积极性,并且在化学教学中拓展学生的思维,开阔学生的眼界,培养学生的创新能力。由于受传统教学方式影响,很多教师现阶段仍然使用单向灌输的教学方式,这样的教学方式很显然不利于学生的学习。因此,教师应当秉承自主、合作、探究式的学习方式,为学生创建问题情境,引导学生主动发现问题,并且培养学生自主解决问题的能力。而如何提高化学课堂中问题情境创设的效率,则是现阶段高中化学教师需要深入思考的话题[1]。……
