Causes and countermeasures of carelessness in mathematics examination. Recently, many students have reported that it is easy to be careless in the process of examination, and they will lose a lot of points that should not be lost every time. Specific symptoms are: wrong topic, problem can be solved, simple sub-topic is wrong, thinking is right, but calculation is wrong, and copying is wrong, resulting in losing points or not counting. There are two reasons for careless loss of points, and the corresponding solutions are given. 1. I am used to relying on knowledge points. Write with knowledge points as soon as you see the question, ignoring what the question asks and what the conditions are. The reason for the wrong question: 1, mostly because I am very familiar with the question and do it without thinking, which leads to mistakes; 2, mental trance error (not serious, this situation is rare, usually very focused during the exam) Interpretation: Many students feel familiar and simple when they see the topic, and start calculating without thinking. As a result, they accidentally went in the wrong direction, didn't understand what the problem was, and ignored the subtle differences between the topic conditions and the topics you were familiar with, leading to mistakes. This is taken for granted and caused by falling into the trap of the proposer. This belongs to the "excited" sloppy type. The real problem of "misreading" refers to inattention, which leads to misreading. Unless the candidate is absent-minded, does not pay attention to the exam, or is sick, it is basically impossible. However, many students think that it is because of trance that they are "careless". In fact, they are too excited or too nervous. They were very excited when they looked at the topic, and then recalled it and unconsciously ignored the details. Or because I haven't seen it, I'm nervous and start to recall knowledge points to get rid of carelessness. Fifth, I concentrate on the problem. Usually practice exercises, pay attention to homework, and use them as exam questions.
