教材是主要的课程资源之一,是师生藉以展开教学活动的重要载体,认真钻研教材,充分利用教材是实现教学效益最大化的首要前提。再好的教材也存在着适应性的缺陷,无法更广泛地兼顾地域、学生的差异,并且其更新的速度往往跟不上时代的发展,设计的内容和形式在一定程度上难以同学生? Teaching material is one of the main curriculum resources, it is an important carrier for teachers and students to carry out teaching activities. Seriously studying teaching materials and making full use of teaching materials are the most important prerequisites for realizing teaching effectiveness. Even the best textbooks also have the adaptability flaw, they can not take the differences between regions and students into consideration more widely, and the update speed often can not keep up with the development of the times. The content and form of the design are difficult to meet with the students to a certain extent.
