宋代学者陆九渊说:“为学患无疑,疑则有进,小疑小进,大疑大进。”可见设疑的重要性,在数学课堂上,设疑有利于激发学生的学习兴趣,为顺利完成教学目标奠定基础。通过设疑诱导,活跃学生的思维,有效地促进学生对数学知识的理解,从而提高学生创造性地解决问题的能力,提高课 Lu Jiuyuan, a scholar in the Song Dynasty, said: “There is no doubt that there is no doubt that there is a problem in the students. There are doubts and minor inferences and big suspicions.” "We can see the importance of establishing suspicion. In mathematics classes, setting doubts and doubts helps stimulate students’ interest in learning. , To lay the foundation for the successful completion of teaching objectives. By doubting the induction, active thinking of students, effectively promote students ’understanding of mathematical knowledge, so as to improve students’ creative ability to solve problems and improve the class
