“做中学,学中做”是新课程倡导的一种学习方法。在初中数学课程教学中,由于许多概念、定理、法则等都是在实践的基础上总结出来的,因而为了使学生对知识产生切身的体验,课堂上应适当开展“动手操作”教学,这样可以充分发挥学生的自主学习能力,获得良好的教学效果。初中生的思维正好处于感性思维向理性思维过渡的时期,在数学教学中,可以结合教学内容让学生 “Do middle school, learn to do ” is a learning method advocated by the new curriculum. In junior middle school mathematics teaching, many concepts, theorems and laws are summed up on the basis of practice. Therefore, in order to make students experience the knowledge personally, the classroom should be properly taught by “hands-on teaching” This will give full play to students’ ability to learn independently and obtain good teaching results. Junior high school students thinking just in the emotional thinking to the transitional period of rational thinking in mathematics teaching, teaching content can be combined so that students
