初中生解物理题时,考虑问题的全面性、逻辑性、严密性还很不足,解题思路不通,结果做错题或做不出题。解题思路障碍是怎样形成的?又怎样突破呢?片面看问题形成的解题思路障碍及其突破。初中有些物理量的大小,由两或两个以上的因素来决定,学生在解题的时候容易以偏概全,只考虑到某个因素,而忽略其它因素,形成解题的思路障碍。例如:“两个直线运动
Junior high school students solve physical problems, consider the comprehensiveness of the issue, logic, tightness is still not enough, problem-solving ideas nowhere, the results of the wrong question or can not make a problem. How to solve the problem of thinking obstacle? How to break it? One-sidedly look at the problem solving problem solving obstacles and breakthrough. Some junior high school physics the size of two or more than two factors to decide, students in the problem-solving is easy to be partial, only consider a factor, while ignoring other factors, the formation of ideas to solve obstacles. For example: ”Two straight lines
