教材改革应有利于引导学生利用已有的知识与经验,主动探索知识的发展和发生;应有利于教师创造性地进行教学。教材的改革应立足于教学实践,而教学实践最优化目标的实现则离不开教学内容的精心安排,离不开对教学内容有目的的整合。教学内容不同于教科书内容,而是教师在教学过程中提供给学生的各种信息。广泛地收集、有目的地选择以及合理地运用是地方素材与教材内容有机地融合以达到优化教学的重要途径。
The reform of teaching materials should help guide students to use existing knowledge and experience and actively explore the development and occurrence of knowledge; teachers should be conducive to creative teaching. The reform of teaching materials should be based on teaching practice, and the realization of the optimization goal of teaching practice is inseparable from the meticulous arrangement of teaching content, and can not be separated from the purposeful integration of teaching content. The teaching content is different from the content of textbooks, but it is the various information teachers provide to students in the teaching process. Extensive collection, purposeful selection, and rational use are important ways for organic integration of local materials and teaching materials to achieve optimal teaching.
