教材是课标的载体,也是教学的依据,在教学实践中,是可以根据教学实际进行教材内容的二次整合和开发利用的。小学科学教材同样也是小学科学教师进行科学实验和教学实践的重要依据。教师一般都是根据教材进行教学目标的制订,教学手段的使用,教学方法的选择。科学教师要善于钻研教材,用好教材。合理地开发利用好教材,直接影响着科学课的有效性。笔者想通过几个教材结构处理的案例,探讨优化教材结构的几种方式。
Teaching materials are the carrier of course standard and also the basis of teaching. In teaching practice, it is possible to integrate and exploit the contents of teaching materials according to the teaching practice. Primary science textbook is also an important basis for primary science teachers to conduct scientific experiments and teaching practice. Teachers are generally based on teaching materials to develop teaching objectives, the use of teaching methods, teaching methods of choice. Science teachers should be good at studying textbooks, good materials. Rational development and utilization of good teaching materials, a direct impact on the effectiveness of science class. I want to deal with several cases through the textbook structure, to explore several ways to optimize the textbook structure.
