一、教师要创设问题型情境,引导和激发学生的学习兴趣问题情境是促进学生建构良好认知结构的推动力,是体验数学应用,培养创新精神的重要措施。教师应尽量给学生设置具有思考价值的问题或悬念,激起学生求知的欲望。教师可以用生活实例来创设问题情境。如教学“打折销售”时,提出 First, teachers should create a problem-based situation, to guide and stimulate students interest in learning situations is to promote students to build a good cognitive structure of the driving force is to experience mathematical applications, an important measure to foster innovation. Teachers should try their best to set questions or suspense for students with their thinking value and arouse their desire for knowledge. Teachers can use life examples to create problem situations. Such as teaching “discount sales,” put forward
