长期以来,教学采用“以解题为中心,从理论到理论,教师灌输、学生接受”的传统教学模式,大部分教师采用的还是那种就一个问题反复讲、重复练,讲“理”,不见“物”的陈腐教学方式,造成学生被动地学习,挫伤了学生的学习积极性,制约了学生的创造能力和创新能力的发展,影响了教育教 For a long time, teaching has adopted the traditional teaching model of “taking the problem as the center, from theory to theory, instilling in the teachers, and accepting by the students”. Most teachers still use the same kind of questions to repeat and repeat the exercises and to talk about “reason”. The lack of “material” methods of stale teaching has caused students to passively learn, dampened students’ enthusiasm for learning, restricted students’ creativity and innovation, and affected education.
