古人云:“凡事预则立,不预则废”,有效的预习,不但可以保证听课的质量,改变学习的被动局面,而且也是提高学生自学能力的有效途径.当然,要求学生课前预习并非就是简单地叫学生提前阅读所学内容,而是既要激发动机,又要加强指导. The ancient saying goes: “Everything is pre-established, not pre-judging,” and effective preparation can not only ensure the quality of the lectures, change the passive situation of learning, but also be an effective way to improve students’ self-learning ability.
