建立物理模型，破解物理解题难关

摘要

高中理科学生面对物理总体的感觉是太难，调查发现，“难”体现在对题中所给的物理信息无法进行有效的筛选，无法将信息提取出来建立物理模型，可见“物理模型”的建立是学生处理问题能力的体现，能否成功建立物理模型成了制约学生成绩提升的瓶颈。文章通过一些具体的例子分析了建模问题。%When high school science students face the physics, their general feeling is too difficult, the survey found that＂ difficult,＂ reflected in the title given in the physical information can not bc effective screened, the information can not be ex- tracted from the establishment of the physical model, showing that ＂physical model＂ the establishment of the issue is the abil- ity of students to handle the embodiment, the successful establishment of the physical constraints of the model has become the bottleneck to enhance student achievement. This article analyzed of modeling by some specific examples.
