In the face of high school mathematics, many students' problems are: they can understand in class and can't do problems; I can do the questions, but I can't do well in the exam; I usually do well in the exam, and the college entrance examination is Waterloo. The problem here is just "change". High school mathematics needs to draw inferences. A knowledge point leads to all kinds of problems, which need to be continuously expanded, condensed and summarized, and then externalized into the repeated training of questions, reflecting the flexible use of thinking and methods, and finally the balance of victory will be inadvertently tilted. The so-called "details determine success or failure" can also be obtained in the same way, such as "I know everything, but I miscalculated or copied the symbol"
Roaring in the mountains, because the jungle, jungle, its momentum has become; In the examination room, the thinking is like a spring and the method is handy. Where does this confidence come from? Mencius talked about "raising the spirit of integrity", and I said "raising tigers as a menace".
It is essential to brush the math questions in senior high school, but there is a time limit in the exam, so we should allocate the time reasonably. However, some students often have the psychology of "once bitten, twice shy" because they are not confident or miss the same type of questions. After repeated inspection, they can put down the next question. This kind of efficiency is not desirable in the exam. As the saying goes, "Picking up sesame seeds and losing watermelon" requires them to be confident enough. Of course, where does the motivation come from? Confident. Where does confidence come from? Have a bottom in my heart Therefore, students need to accumulate at ordinary times, such as vector operation of solid geometry in science, and do more problems at ordinary times. After accumulating to a certain amount, the accuracy is already very high, and the calculation will hardly go wrong. Then if you encounter this problem in the exam, you will naturally have confidence and do it step by step according to your usual habits. I believe the accuracy can still be maintained. This is the tiger with a heart. For example, I brought a student, who has a habit of doing problems slowly. In order to solve a problem, it is easy to overturn his thoughts and ideas at any time. Obviously, everyone looked at him with the right steps, but he hesitated for a long time and applied correction fluid to start over. This is a typical "inner self-confidence" student. The root cause is not enough accumulation at ordinary times, or previous study habits and problem-solving habits. Therefore, in addition to explaining the knowledge points normally throughout the summer vacation, I also emphasized the "momentum" problem of doing the problem from time to time, without correction fluid. If a quiz is excellent, I will give priority to encouraging praise and slowly cultivate his self-confidence. Later, I made great progress, at least when I did the problem, I answered it without hesitation. This is also an improvement.
"With accurate and beautiful maps and map-reading partners, all the places of interest in the ends of the earth can be called." Beside the Map is one of the few collections of essays in Mr. Yu Guangzhong's works. It is neither an ordinary essay nor a beautiful article, but an interesting and reasonable article. The article is very short and the ink is particularly careful. "Carving insects like dragons" can make sense in one sentence. Whether teaching or learning high school mathematics, the attitude of "carving insects like dragons" echoes the way of "smelling roses".
Many types of math problems are usually done in NMET, but there are still many people who make mistakes in NMET, not because they can't, but because they made mistakes and didn't handle the details properly. Try to imagine a picture of a tiger sniffing wild roses quietly, without any sense of disobedience, which is needed to learn math well. As the saying goes, "the lion should try his best to fight the rabbit." Details determine success or failure, so I won't go into details here. For example, mathematics, as we all know, is a compulsory test in the college entrance examination. Even if you take it out alone, almost all high school students can understand it, but the college entrance examination is still prone to mistakes. The mistake lies in the details, ignoring the definition domain of the function. Some people will make mistakes even when they are in the third year of high school, and they are more likely to get confused under the tension of the college entrance examination, so even if the first element of the function is the definition domain from high to high. I used to have a senior three candidate with a medium grade. She can do all the basic questions except some difficult ones. However, when she finished the exam, she regretted being "angry" and kept crying. So, she repeatedly knocked on the details in class and once asked her to write the word "serious" on the front page of the test paper. As a result, she unexpectedly won the first place in the class. This is ... Of course, this approach is just an example. What we want to emphasize is that we should not only learn how to do high school mathematics, but also pay attention to details. A "sloppy" is "Waterloo".
Siegfried Sassoon, a contemporary English poet: "The tiger smells on me"
Roses. "
Mr. Yu Guangzhong translated it into Chinese: "There is a tiger sniffing roses in my heart."
I reinterpret it as my teaching method: "I am as confident as a tiger in learning mathematics, if I smell roses carefully."
