科学方法的教学已经成为物理教育教学的重要内容,用科学方法组织初中重点物理知识教学,能够使学生较全面地掌握常用的物理科学方法。控制变量法是初中物理中经常用到的科学方法之一,本文将在《欧姆定律》教学实践中,紧抓“学生主体的行为和思维”这一证据意识出发进行控制变量法的显化教育教学。 The teaching of scientific methods has become an important part of physics education and teaching. The teaching of key physics knowledge in junior high schools with scientific methods can enable students to master the commonly used physical science methods in a comprehensive way. The control variable method is one of the most commonly used scientific methods in junior middle school physics. In this article, we will focus on the “Ohm’s Law” teaching practice, grasp the “student’s behavior and thinking” Teaching and learning
