《物理课程标准》指出“物理课程的构建应注重让学生经历从自然到物理、从生活到物理的认识过程,经历基本的科学探究实践,注重物理学科与其他学科的融合,使学生得到全面发展”.初中物理教学,通过观察和经历探究实验过程是学好物理的重要方法.由于学校的实验场地局限于校内,满足不了新课程背景下数量繁多、形式多变,探究性的物理实验教学的要求,有的探究性实验必须到校外尤其是 The “Physical Curriculum Standard” states that “the construction of physical curricula should emphasize that students should go through the process of understanding from nature to physics and from life to physics, go through basic scientific inquiry practice, pay attention to the integration of physics and other disciplines, Development. ”Physics teaching in junior high school, through observation and experience to explore the experimental process is an important way to learn physics.As the school’s experimental site is confined to the school, can not meet the new curriculum context of a large number, changing forms, inquiring the physics experiment teaching Some inquiry experiments must be made outside the school, especially
