First, learning is too mechanical and there is no in-depth thinking.
When learning mathematics, some students will not go into the ins and outs of formula theorems and reasoning methods, but memorize them directly. What junior three students need to understand is that many formulas and theorems can be derived, which can actually help to understand the basic knowledge. If you don't master this piece, you won't be handy to use.
Mathematics is a very logical subject, so thinking is the core of mathematics learning, especially doing problems. Mathematics examination is to test the application of knowledge points, understand these knowledge points, and then solve problems, and consolidate the knowledge learned through solving problems. When doing problems, students in grade three should learn to use the knowledge points contained in the thinking questions, the similarities and differences between the questions, the connections and so on. By thinking about integrating knowledge points, you will gradually refine your thinking, and it will be much smoother to solve such problems in the future.
Second, the wrong question only looks at the answer, not summing up the analysis.
When you make a mistake in solving a problem, you just look at the final answer and think that you have solved the problem yourself. This is the most serious mistake in the learning process. Senior three students must analyze the questions they have done, especially the wrong questions on the test paper. This book is a piece of waste paper unless it is read correctly. It is necessary to review and sort out the "wrong problem set" of the senior high school entrance examination.
Junior three students need to understand that where they make mistakes is the difficulty of learning. If we find the law and grasp the key points, we can review the remedial measures in a targeted manner. Junior three students should not be afraid of problems, and should not have the mentality that they will lose face if they can't solve the problems. The secret of improving your problem-solving ability is to study as much as possible, really put yourself into it and persevere. Junior three students need to learn to analyze problems, and to be a good problem solver, they need to divide the problems into several parts to analyze, carefully interpret and thoroughly analyze each problem, so as to be good at solving problems.
Third, problems can be delayed and there is no sense of efficiency.
When some junior three students encounter problems, they often become lazy and want to solve them tomorrow. Even they are too shy to ask questions, which leads to more and more loopholes. A junior high school student who is good at learning needs to dare to ask questions and learn how to solve them. Students in Grade Three should dare to question and be good at expressing their feelings. Great inventions and great progress through the ages began with bold assumptions and dare to question.
One problem that junior three students need to know is the knowledge loophole. The longer the delay, the bigger the loophole, and the result will naturally not be good. Therefore, the only solution is to find and solve problems as soon as possible. Junior three students must learn to finish what they can do today, and never leave the questions until tomorrow. Usually after finishing a problem, students in Grade Three may wish to ask other students to see if they have come up with other more ingenious ideas, methods and skills to solve the problem.
Fourth, the draft is too random and disorganized to be found.
Many students have lost points because of messy drafts, wrong conditions or wrong answers. This is the result of random drafting, and it is not easy to check for mistakes. Draft, standard writing, clear steps and title number. This method generally does not make mistakes in copying the problem-solving process and the final check. Once there is a calculation error, it is easy to find out where the problem lies and remedy it in time!
Excellent draft is valuable learning wealth, full of students' thinking traces of analyzing and solving problems, which not only greatly improves students' learning efficiency, but also effectively improves students' academic performance. Grade three students should pay attention to the habit of making clear draft rules, improve the confidence and care of large-scale calculation, and achieve the unity of speed and accuracy in the examination room.
Five, only reading without doing problems, learning will not be used.
Some junior high school students have misunderstandings about learning, thinking that they understand and know how to do problems, but they always can't get high marks. In fact, it is because they have not started to calculate. For the sake of "efficiency", some students feel that it takes time to review and do a big math problem. Sometimes they simply write down their ideas and think that this problem can be done, so they quickly skip it and make a superior mistake. Learning mathematics must pay attention to "living", not only reading books without doing problems, but also burying oneself in doing problems without summarizing and accumulating. We must be able to get in, jump out of the textbook knowledge, and find a suitable method according to our own characteristics.
Junior three students need to understand that it is better to pass it through the eyes a thousand times than through the hands. It is very important to do the problem, even if it is difficult to calculate, you should patiently work out the correct answer. This process can not only improve one's computing ability, but also find the connection of some knowledge points in doing problems, as well as check and fill gaps and strengthen training.
If junior three students want to learn junior high school mathematics well, they must cultivate their mathematical thinking ability and get rid of the bad habits that affect their mathematical performance.
