一背景与主题高中物理实验教学有以下四个特点:(1)以学生为本的理念在不断引导着教师的教学行为。(2)教师意识到实验教学是物理教学的必要手段和重要组成部分,能促进学生自我构建知识,培养观察能力和思维能力。(3)教学内容的选择。教师以学生实际存在问题的内容为重点或切入点。(4)教学方法呈现多样化。利用实验促进学生对新知识的主动构建及在课内完成预设目标是教师面临的新问题。下面就两位教师执教的“静摩擦力”的课堂实验教学实录进行切片分析。
A background and theme of high school physics experiment teaching has the following four characteristics: (1) The concept of student-centered teaching teachers continue to guide the behavior. (2) Teachers realize that experimental teaching is an essential means and an important part of physics teaching, which can promote students to build their own knowledge, develop observation ability and thinking ability. (3) the choice of teaching content. Teachers focus on or focus on the actual problems of students. (4) diversification of teaching methods. Using experiments to promote students’ initiative construction of new knowledge and accomplish the preset goal in class are new problems that teachers face. The following two teachers coached “static friction ” classroom experimental teaching records for slice analysis.
