《约数和倍数》这一节概念起始课我已经试教了3次,最后执教方案的抉择主要集中在遵循教材还是创编教材两套设计方案上。我试着从学习材料的选择、呈现方式的改变和学习效果的检测这三个模块着手比较,想深入研究如何有效地把教材转化为学材,如何在常态的课堂中彰显新理念,创造智慧课堂?现整理出一些有价值的内容,与各位同行探讨。 “The divisor and multiplier” concept starting section I have tried teaching 3 times, the final choice of coaching program is mainly focused on teaching materials or compiling textbooks on two sets of design options.
