物理实验题是用来检查学生实验能力的一类练习题,它需要在观察和实验的基础上进行解答。初中学生解这类习题时,常常出错。教学中教师帮助学生分析其错解原因,不仅可以促进学生正确解答实验题,而且可以促进学生手脑并用,提高他们的实验技能。初中学生错解物理实验题的主要原因有如下几点。一、粗心大意,审题不细审题是解题的关键,特别是审读物理实验题务必要先领会题目的意思,注意寻找概念间的相互关系,挖掘题中的隐蔽条件。这样,才能抓住问题的实质,利于问题的解决。例1(填空题)、有一同学用最小刻度为
The physics lab question is a class of exercise questions used to check students’ experimental ability. It needs to be answered on the basis of observation and experimentation. When junior high school students solve such exercises, they often make mistakes. Teaching teachers to help students analyze the reasons for their misunderstandings can not only promote students to correctly solve experimental problems, but also promote the use of their hands and brains to improve their experimental skills. The main reasons why junior high school students misunderstand physics experiment questions are as follows. First, carelessness, examination of questions is not the key to solving the problem, in particular, reading the physics experiment must first understand the meaning of the topic, pay attention to the search for the relationship between the concepts, to explore the hidden conditions in the title. In this way, we can seize the essence of the problem and facilitate the solution of the problem. Example 1 (fill in the blank), a classmate with the smallest scale
