单摆运动呈现了由线性运动向混沌的过渡,扮演着宇宙的基本角色;单摆的物理特性研究,体现了典型的近代科学方法论,为建立“单摆”与“自由落体运动”关系提供了可能。同时,它在科学教学中扮演着重要的角色。论文基于课程标准对“单摆”教学要求的定位与教材对“单摆”教学内容的描述,反思了新课改中单摆教学对科学本质关注的缺失,提出以“历史一探究一反思”方法开展“单摆”的科学本质教学。
The movement of pendulum presents the transition from linear motion to chaos and plays the basic role of the universe. The study of the pendulum's physical characteristics embodies the typical modern scientific methodology. It is of great significance to establish a “pendulum” and “free-fall motion” “The relationship offers the possibility. At the same time, it plays an important role in science teaching. Based on the curriculum standard, this paper describes the teaching requirements of ”Pendulum“ and the teaching materials of the ”Pendulum“, describes the lack of attention to the essence of science in the new curriculum reform, Explore a reflection ”method to carry out “ pendulum ”science essence teaching.
