物理是什么样的?每个人心中都会有不同答案:神秘、高深、奇妙、有趣……可是为什么对不少高中生来说,物理却是枯燥、乏味、难学,令人头疼的.作为物理教师在教学实践中,是否起到了“引领学生进入深邃又曼妙的物理世界,激发学生探索物理规律的欲望,教给学生探究物理的思想和方法”的重要作用?抑或是背道而驰了?寒假期间,笔者有幸观看了美国麻省理工大学(下文简称MIT)的公开课视频——由Walter Lewin教授执教的经典力学课程.虽然这是一门大学课程,但是它的范围和难度与我们的高中物理课程大抵相当.这节课给我留下了深刻的印象,Walter Lewin教 What is physics? Each person will have different answers in my heart: mysterious, profound, wonderful, interesting ... But why many high school students, physics is boring, boring, difficult to learn, a headache .As a physics teacher In teaching practice, does it play an important role in leading students into the deep and graceful physical world, inspiring students to explore the laws of physics and teaching students to explore the ideas and methods of physics? Or does it run counter to the nature? During the winter vacation , I was fortunate enough to watch a video of the MIT Open Classes - a classic mechanics class taught by Professor Walter Lewin.Although this is a college course, its scope and difficulty relate to our high school physics The lesson was pretty much the same, and the lesson impressed me a lot, Walter Lewin taught
