例题的功能不仅是知识点的示范应用,有大量潜在的数学功能需要开发,挖掘这些潜在功能的过程,正是学生获得知识和技能的关键.通过提出问题和解决问题,可以激发学生的学习兴趣,培养和提高学生的分析能力和应用水平,培养和提高学生的探索能力和创新精神. The function of the example questions is not only the demonstration application of knowledge points, but also a large number of potential mathematical functions that need to be developed. The process of mining these potential functions is the key to students acquiring knowledge and skills. By raising questions and solving problems, students’ interest in learning can be stimulated. , Cultivate and improve students’ analytical ability and application level, develop and improve students’ exploration ability and innovation spirit.
