力学是物理知识的重要组成部分,也是学生容易与自己已有的错误的潜意识相混淆的部分。为让学生正确认识力学知识,教师往往用实验来让学生体验和理解知识的正确性。对于刚刚初学物理的学生,实验既熟悉又陌生,熟悉——小学做过实验,陌生——不知道如何去进行实验,在实验中如何操作,整体思路零乱。在这种情况下,迫切需要一种简而易懂的有效的教学手段。一、概念图的介绍美国康奈尔大学诺瓦克教授对奥苏贝尔的有意义学习理论进行了深入研究,并提 Mechanics is an important part of physical knowledge and a part of students’ confusion with their own mistaken subconscious. To enable students to correctly understand mechanical knowledge, teachers often use experiments to let students experience and understand the correctness of knowledge. For students who have just started to study physics, the experiment is not only familiar but unfamiliar and familiar to them. Experiments in elementary schools are unfamiliar. They do not know how to conduct experiments and how to operate in experiments. Under such circumstances, there is an urgent need for a simple and effective teaching method. First, the introduction of the concept map Professor Novak at Cornell University conducted a thorough study of Ausubel’s meaningful learning theory and proposed
