在初中物理教学中,我发现学生在解答说理题时,常常出现这样或那样的错误,归纳起来有以下十五种.1.答非所问脱离题目所问的内容去解答,答走了题.例1.在地上滚动的小球,为什么越滚越慢?(第一册第70页第1题)错解:小球由于惯性,要保持原来的运动状态,所以,小球能继续滚动.分析:题目要求解答的是小球越滚越慢的原因,而不是要求回答小球能继续滚动的原因,显然在解答时,没有仔细分析题意,反复推敲
In junior middle school physics teaching, I found that when students answer the questions, they often have one or more mistakes. They can be summed up in the following fifteen kinds of questions. 1. Answer non-questioned questions and ask them to answer the questions and answer questions. Example 1 The ball rolling on the ground, why roll more slowly? (Volume one of page 70, Problem 1) Misunderstanding: The ball must maintain its original state of motion due to inertia, so the ball can continue to roll. Analysis: The title asks to answer the reason why the ball is getting slower and slower than to ask why the ball can continue to roll. Obviously when it comes to answers, the questions are not carefully analyzed and the questions are repeatedly considered.
