一、开发和利用数学教材资源《基础教育课程改革纲要(试行)》中指出:“没有课程资源的广泛支持,再美好的课程改革设想也难变成中小学的实际教育成果。”新课程改革提倡“用教材教”而非“教教材”的教学理念。在日常的课堂教学中,教者应充分尊重教材,尊重教材的编排方式与编写意图,在此基础上理解教材,针对性地对教材内容作一定的增减或调整。以“加法交换律”一节内容的教学为例,教学时,教者没有直接让学生概括加法交换律,而是引导学生依据情境图列出两种算式求总数,并对这些算式能否成立
First, the development and utilization of mathematics textbooks resources Basic Education Curriculum Reform (for Trial Implementation) pointed out: Without the broad support of curriculum resources, and then a good idea of curriculum reform is difficult to become the actual education of primary and secondary education.
