利用多学科素材助力初中函数教学

Promoting the Development of the Function Teaching in Junior High School by Use of Multi-Disciplinary Materials

函数是初中教学的难点。学生初学函数时正处于形象思维向抽象思维转化的关键期,因此,他们对于函数的认识不能完全脱离感性思维,需要大量的实例支撑,这些实例广泛存在于其他学科之中。为帮助学生克服初学函数时的困难,可从物理、化学、生物、地理等相关学科选取素材,深化学生对函数概念和性质的理解,培养他们的逻辑思维能力,并促进学科教学的跨界融合。

thinking.Therefore,their understanding of functions cannot be divorced from affective thinking,and need to be supported by a large number of examples,which exist widely in other disciplines.In order to help students overcome difficulties in learning functions at the beginning,teachers can select materials from the related subjects such as physics,chemistry,biology and geography to deepen students’understanding of the concept and nature of functions,train their logical thinking ability,and promote the interdisciplinary teaching integration.
