教材是教学活动的重要资源,提供了教与学的范例和师生对话的中介。数学教材(北师大版)的编排有个明显特点,一节课的学习先是创设数学学习情境,展示本课学习内容,接着是“试一试”、“练一练”等栏目分层推进。在教学中,必须充分利用好这些宝贵的学习资源,不能例题一讲,学生一练,几个练习一做就算完成了。教师作为教材的开发者和创造者,应创造性地利用好教材。新课程已实施几年,结合本人的工作实践,试就如何挖掘利用教材内容,充分发挥教材中的习题功能谈几点看法。
Textbooks are an important resource for teaching activities and provide an example of teaching and learning and an intermediary for dialogue between teachers and students. Mathematical textbooks (Beijing Normal University Edition) arrangement has a distinct characteristic, a class of learning is to create a mathematical learning situation, show the contents of this lesson, followed by “try ”, “practice a practice ” and so on Hierarchical promotion. In teaching, we must make full use of these precious learning resources, not an example of a problem, the students a practice, a few exercises even if done. Teachers, as developers and creators of textbooks, should make creative use of textbooks. The new curriculum has been implemented for several years, combined with my work practice, try how to tap the textbook content, give full play to the exercises in the textbook to talk about several points.
