1引言  理想化方法是中学物理中非常重要的一种科学思维方法, 这种方法可以概括为“去粗取精、抓住主要矛盾、运用逻辑推理、建立物理模型”.特别是我们在中学物理解题中,一定要根据所研究对象的具体情况, 确定问题主要的、本质的因素,舍弃其次要的、非本质的因素,将条件复杂的实际过程转化为简单的理想化过程.这样,我们就可以透过研究对象的表面现象,比较容易地发现研究对象的本质及变化规律,从而给中学物理解题带来
《浮力》是初三物理较为难学的一节内容,是学生在掌握重力、摩擦力、压力、密度和压强等知识的前提下进一步拔高的内容,主要教学内容分为:浮力的概念、探究浮力大小的影响因素、阿基米德原理等三部分重点知识.在应用练习上关键是由感性认识转为量化计算,要设计多个物理量的综合分析,再选择适合的计算公式,这是学习浮力的难点.  我处理本节的观点是:教学内容要先分清主次,三项重点内容必须课堂学明白、弄清楚,关于浮力的

1问题的提出  2011年9月19日,江西九江市庐赛阳中心小学3名10岁左右的女学生,相约从一座民房的二楼跳下,均摔成重伤 ,而跳楼原因竟是“跳楼死了就不要写作业了”.对于“小学生相约跳楼自杀”这件事,不少人将其归罪于那“写了一天还是无法完成”的作业.这需要引起我们教师的警觉与反思:是不是我们的作业设计与布置存在严重问题?众所周知,现在的学生(尤其是高中学生),课余时间几乎全被作业占据,而多数作业
