在教学实践中,很多老师十分重视例题的教学,却忽视了对习题的设计研究,缺乏对习题内涵的深度挖掘,从而弱化了习题应有的数学价值与思维提升功能。那么,习题与试题又要进行怎样的创新设计才能适应这样的变化,恰当发挥导向作用呢?带着对这些问题的思考,笔者尝试通过对传统习题进行创新设计,以期有效发挥习题在提升思维价值、发展学生思维能力方面的作用。一、设置习题情境,再现思维过程教学实践告诉我们:单调、呆板的练习,学生会感到枯燥无味,淡化学习的积极性,促使注意力分散,因此,习题的设计要紧扣教学目标、突出重点,让学生练
In teaching practice, many teachers attach great importance to the teaching of examples, but neglect the design and study of the exercises, lack of deep excavation of the connotation of the exercises, thus weakening the mathematical value of the exercises and the function of thinking to enhance. So, what kind of innovative design of exercises and test questions should be adapted to such changes, properly play a guiding role? With these questions, I try to innovative design of traditional exercises in order to give full play to exercise in enhancing the value of thinking , The development of students thinking ability. First, set the exercise situation, reproduce the thinking process teaching practice tells us: monotonous, dull exercises, students will feel boring, dilute the enthusiasm for learning, prompting distractions, therefore, the design of exercises should be closely linked to teaching objectives, give prominence to the focus, so that students practice
