提高中学生解物理题的能力,除了加强基础知识教学外,培养学生正确的思维步骤也是很重要的。教学实践表明,不少学生尽管能熟记一些定律、公式、解决某些单一的习题,但是碰到稍为复杂一点的物理题,思维就混乱了,显得束手无策。他们不能从错综复杂的关系中,确定解题的步骤,顺利解决各种类型的物理题。例如,在近年的高考中有这样一道题:一个 U 型导体框架,宽度 To improve the ability of middle school students to solve physics problems, in addition to strengthening basic knowledge teaching, it is also important to cultivate students’ correct thinking steps. Teaching practice shows that although many students can memorize some laws, formulas, and solve some single exercises, when they come across a slightly more complex physics problem, their thinking is confusing and they are helpless. They can’t determine the problem-solving steps from the intricate relationships and solve all kinds of physical problems smoothly. For example, in recent college entrance examinations there is such a question: a U-shaped conductor frame, width
