数学教学中,习题训练是重要的环节之一.习题训练是巩固新授知识,形成技能技巧,培养良好的思维品质,发展学生智力的重要途径.但是,教师还必须掌握课堂教学中例题、习题的配置时机,盲目、随意的加深或降低知识要求,都是低效甚至是无效的教学.那么,什么时间、什么场合、出现什么样的数学题?新授课应该选择怎样的例题,习题课讲授应该选择怎样的例题,单元复习课、全面复习课又该选择怎样的数学题?事实上 Exercises training is one of the important links in maths teaching.Exercise training is an important way to consolidate the new teaching knowledge, form skills and skills, develop good thinking quality and develop students’ intelligence.However, teachers must also master the examples, exercises in class teaching Of the allocation of timing, blindly, arbitrarily deepen or reduce the knowledge requirements, are inefficient or even invalid teaching.So, at what time, what occasions, what kind of math problems? New class should choose what kind of example, exercise class teaching What kind of questions should be selected, unit review class, comprehensive review of the choice of what kind of math? In fact
