There are many factors that affect students' ability to examine questions, such as the presentation form of teaching materials. After the new curriculum reform, the choice of teaching materials has changed a lot, emphasizing the close relationship between mathematics and students' lives, and also putting forward higher requirements for teachers and students in teaching. The following are several cases of mistakes in examination.
1. If you haven't finished reading the topic or haven't thought about it after reading it, press "Old Impression". The main reason for this mistake is the negative influence of "thinking set". If there is an application problem: Mom bought 12 apples and ate six, how many are left? As soon as students see the word "one * * *", they conclude that the problem is "addition", and the problem is not to read carefully. Another example is "Write two multiplication formulas and two division formulas according to the given multiplication formula". Some students don't read the questions at all. When they saw the problem, they wrote four multiplication formulas. They thought they would continue to write formulas.
I didn't pay attention to the key words in the topic. This is because primary school students only pay attention to the whole, but not to the small places, so they read the wrong questions and cause the wrong perception, so they list the wrong formulas. For example, a multiple-choice question in a math exam: What is the sum of four sixes? Choose the wrong answer below. A.4X6 B.4+6 C.6X4 Half of the students choose A or C, and the key is that they carefully examine the keyword "error" in the topic. Of course, some second-grade children don't quite understand the meaning of "mistake".
For the students in Grade Two, they don't know many words. Of course, this will also greatly affect their understanding level. Several times, I stressed that I should look at the emotional questions carefully every time I take an exam or finish my exercises, but some students still read the questions wrong. Some children really answer irrelevant questions, and some answers really make you smile. I asked those children, and the result was: I didn't read the topic, because there were too many words in the topic that I didn't know or understand, so I simply didn't read it.
It is very important to cultivate students' good habit of examining questions. A good habit of examining questions is the beginning of doing the right thing. Some children in my class never look carefully before answering questions, but do it after reading them. Since I began to cultivate their habit and ability to examine questions, their grades have been greatly improved. In order to cultivate students' good habit of examining questions, teachers must always pay attention to the cultivation of students' good study habits and try to curb some bad habits of examining questions. When examining questions, students are required to be "eye-to-eye, mouth-to-mouth, hand-to-hand and heart-to-heart". After you get the topic, don't answer blindly, read more, read out your feelings, read out your deep meaning, and point over while reading, leading to the core or requirements of the topic; Finally, pay close attention to the meaning of the topic. Specific practices are as follows:
First, the examination of questions is the basis of examination of questions.
Mathematics reading problem is a necessary means to understand the meaning of the problem. By reading the questions, make students clear the meaning of the questions and prepare for further thinking. Children in lower grades are not well educated. If teachers and parents often do it for them, and teachers and parents don't look at the questions, students will not do it, thus forming dependence. Therefore, in the usual class, students should be trained to try to read the questions themselves. If they encounter unfamiliar words, I will write them on the blackboard and note pinyin for them to read. Students should read the questions carefully, word for word, correctly, without missing words, without adding words and without stopping sentences. Because junior students are slow in reading and weak in understanding, they should also be guided to read the questions, put new words and understand inappropriate words. After the students finish reading, let them tell stories. Ask to repeat the conditions, questions and meanings of the topic in a language you are familiar with. If students read the questions carefully in this way, children will naturally understand the meaning of the questions and solve them. In the usual practice, I will ask students to mark the keywords and words they read, so that there will be no mistakes in doing the questions.
Second, observation is the guarantee of the exam.
Most of the questions in the lower grades are presented to students in the form of pictures and texts. Therefore, in mathematics teaching, in order to improve students' ability to examine questions, teachers must also consciously guide students to learn to observe, cultivate students' observation ability, and then improve students' ability to examine questions. Observe in order. For example, the "Festival Square" in the first volume of the second grade of Beijing Normal University Edition is colorful and rich in content, which is easy for students to jump with excitement. At this time, students can be guided to observe from top to bottom and from left to right. This will directly guide students to pay attention to the main information, so that under the guidance of teachers, through further observation, we can find the characteristics of quantity and the relationship between quantity and quantity. In class, students are required to have clear observation and try to attract students' attention to valuable information. Slowly, students can learn to observe pictures from a mathematical point of view and find useful mathematical information to solve practical problems. For the problems presented in the form of pictures and texts, after guiding students to observe the pictures carefully, they should express the observed information in their own language in an orderly way.
In addition, long-term guidance and training should be carried out to cultivate students' habit of carefully examining questions. Every time you do exercises or exams, let the students read the topic by themselves, let them say the meaning of the topic by themselves, and train them to pay attention to the meaning of the keywords in the topic. Connecting with practice, improving teaching methods and cultivating students' habit of reading and examining questions carefully. Follow good advice and cultivate students' habit of doing homework independently. Children's learning is an effort to test themselves. Many students rely on it, waiting for teachers or classmates' answers and even parents' guidance. Students should put an end to excessive tutoring in their usual study. Get into the habit of finishing your homework. We should warmly encourage every student, cultivate the habit of studying hard, thinking well, questioning and asking difficult questions, give more guidance, and cultivate the habit of previewing before class. For example, there is a math problem that draws 10 triangles. Ask the students to color the fifth circle from the left and circle the first five circles from the left. Be sure to let students read the questions carefully, distinguish between "left" and "right", and also distinguish between "5" and "5".
In short, teachers should always remind students to carefully examine questions, carefully examine questions, constantly set an example for students, teach them the skills and methods of examining questions, and improve the correct rate of solving problems.
