案例式教学是数学教学实现有效教学的一个很好的手段,笔者经过对近几年教育教学工作的总结.从案例问题的设计要精确,要能全面体现三维教学目标、案例的设计要有梯度、要达到提高学生能力的效果、案例的设计要注重层次性,促进全体学生和谐发展等三个方面对案例式教学在高中数学中的应用进行探讨.著名教育家布鲁纳先生曾经指出,培养学生的推断、假设、实证并最终解决问题的能力可能是教学过程中最需要重 Case-based teaching is an effective way to realize effective teaching in mathematics teaching. After summarizing the education and teaching work in recent years, the author should design the case problem accurately, and fully reflect the three-dimensional teaching goal. The design of the case should have a gradient , To achieve the effect of improving the ability of students, case design should pay attention to the level, and promote the harmonious development of all students to explore the application of case-based teaching in high school mathematics .Browna famous educator once pointed out that the training Students’ ability to infer, hypothesize, empirically, and ultimately solve problems may be the most needed weight in teaching
