俗话说:“眼过百遍,不如手过一遍。”心理学告诉我们,操作是手与眼协同活动对客观规律的感知过程,又是脑与手密切沟通把外部动作系列转化为内部语言形态的智力内化方式。因此,数学离不开动手操作,教师应让学生在操作中探索,探索中创新。下面就“体积和体积单位”这节课的教学谈一谈我的几点做法:一、在导入新课时激发学生的创新欲望导入新课尽管方法各异,但都应为激发学生的创新欲望服务。上课时我设疑激趣说:“同学们,这节课我们用实验的方法来 As the saying goes: ”Psychology tells us that the operation is the hand and eye synergistic activities of the objective laws of perceived process, but also the brain and hands in close communication to the external action series into internal The Way of Intelligence Internalization of Language Form. Therefore, mathematics can not do without hands-on operation, teachers should allow students to explore in the operation, to explore innovation. The following on the “volume and volume unit ” teaching talk about my practice: First, in the introduction of new courses to stimulate students’ desire to innovate into the new lesson despite the different methods, but should be to stimulate students Innovation desire service. When I was in class, I was skeptical: "Students, this lesson we use experimental methods
