Inefficient brush questions may have the following problems:
1, the brush question is not a real brush.
Listen, don't do this! Eye to eye, hand to hand! Only pursue quantity, not quality! Quality, quality, must first ensure quality, and then pursue quantity, this is quality! Sometimes, but simply write down your own thoughts and make a superior mistake. Do the questions carefully and patiently! Only by doing this can we know our own shortcomings and achieve the purpose of checking and filling the gaps.
2. Rote the process and ideas of solving problems.
In the process of doing the problem, you can find a solution by constantly turning over the books, constantly looking for the problem, and persisting in doing the problem. I'm used to reading books if I don't understand them, and looking for them if I don't remember or understand them! Especially when doing homework, this habit is more obvious! In this case, it is very likely that you will not be able to master relevant knowledge points and solve problems for a long time! Only by knowing what you have learned, sorting out and digesting the course content in time, and integrating new knowledge into your existing knowledge structure system, can you connect them well, find their inherent essence, and explore possible solutions to various problems. Maybe I didn't remember something at first, and it's normal to turn over the books. But with the deepening of my study, I should try to "quit" teaching materials and reference books when I do math problems. Only in this way can I make continuous progress, and my knowledge structure and problem-solving ability can be really strengthened.
3. Fear of difficulties and procrastination.
The study of mathematics is closely related. If the problem is not solved immediately, it will easily lead to the inability to continue the later study! In the process of learning, there is a mentality that learning is for exams, and there is a lucky mentality for exams, so you can bypass or put aside problems and leave them for later thinking! There are more and more problems that cause mistakes and incomprehension, and even lead to the inability to continue the follow-up lectures and learning process, thus losing interest and motivation in learning! Learning math is like upgrading the game. It is a process of constantly improving your level (level) in the process of constantly overcoming obstacles and solving problems. Only by solving the previous problems can a person enter the next level.
4. Don't think and summarize problems.
The process of writing homework only pays attention to the topic, and the answer is directly put aside! No thinking, no association, no analogy, no summary, this process is just like the process of memorizing and solving problems. The final result is to follow the gourd painting, and a little deformation and change will make you look stupid! Think before solving math problems, and learn to summarize, reflect and improve after finishing them. Only through thinking, can we effectively integrate knowledge points, slowly refine the ideas for solving problems, and then form a "routine" for solving problems, and truly "do the problem as the key link"! If you encounter the same kind of problems in the future, you will be able to solve them easily and naturally! Every reflection and summary will deepen the impression, and it is also possible to form new knowledge and understanding from different angles, so as to continuously integrate and enrich your existing knowledge system.
Six points that should be paid attention to in mathematics examination
Fill in the blanks
1. The simpler the question, the more careful it is, because there is likely to be a trap.
Be careful to answer weird questions, you may have miscalculated.
3. Ask more questions with numbers, and have you missed the answers. For example, if the answer "1" appears, we should consider the situation of "-1".
4. The final fill-in-the-blank questions are generally difficult questions. If you can't solve it right away, skip it. After all, this question is only 3 points, so think about it after you answer it.
5. For the fill-in-the-blank questions outside the outline, you can consider the idea of guessing the questions, which can save a lot of calculations, and the answers to such questions are more likely to have smaller integers.
Second, multiple choice questions
1. There is only one correct option in the multiple-choice math question, so be sure to look at all the options before making a choice.
2. If you don't understand at all, choose C. At least from the probability of choosing a topic in China, C has the highest winning rate.
Third, calculate or solve the equation.
1. When there are more than two digits, you must use a pen. Never trust your mental arithmetic too much.
2. If you have a calculation, don't grab time, try to be correct once, otherwise the calculation error will be difficult to find out because of the inertia of thinking.
3. Each question should be brought back to the original test to prevent inconsistent answers from appearing.
4. Be more careful about weird answers and check the calculation process immediately.
Fourth, geometric proof or application questions
1. Add auxiliary lines to be described in standard language. For example, in "triangle ABC, AM is perpendicular to BC, BC is in M", the test of "cross BC" cannot be omitted. Otherwise, the strict teacher may deduct your points.
2. The description of auxiliary lines cannot be used as a known condition.
3. If it is an application question, you need to write an "answer". When describing the answer, we should check the completeness or linguistic meaning of the subject-predicate object to avoid making mistakes in the last step of writing the answer. For example, "it took Xiao Li 50 minutes to reach his destination" cannot be written as "it took Xiao Li 50 minutes".
4. Omission is strictly prohibited in the answer.
Fifth, the finale
1. Possible question type: linear function plus triangle or quadrilateral. There are three or four questions, which basically cover coordinates, analytical expressions, line segment length, angle calculation, moving point, area, and whether the previous conclusions are valid under other conditions.
2. After asking and checking, you can answer the next question only if you are sure there is nothing wrong, otherwise you may be wrong in the front and wrong in the back.
3. Pay special attention to two aspects: first, whether there are any calculation errors, and second, whether there are any missing or irrelevant answers. After checking in the previous way, there is no need to check again.
4. If the coordinate or line segment has multiples of root number 2, root number 3 or 3, 4 and 5, then the graph in the linear function is very likely to be a special graph of 30 degrees, 45 degrees, 60 degrees, right angles or three strands, four chords and five, and geometric characteristics can be considered.
If there is a folded symmetrical figure, it is very likely to establish a vertical line segment. If necessary, the slope of the vertical line segment is multiplied by-1, and the proportional nature of the line segment is considered when calculating the coordinates.
Intransitive verb others
1. Before the exam, you should be quiet and not move. You shouldn't run, fight, shout or sweat. You shouldn't review math any more. You can choose to be quiet and slow down.
2. Read each question at least three times, underline the key words with a pencil, and then substitute the answers into the questions to test.
3. When encountering a problem, I think that I may have overlooked a certain condition. If you still don't have a clue after 5 minutes, then jump over. Great achievements are still waiting for you.
4. In the last 15 minutes, you must start checking, and put aside any questions you can't do. You can't throw away questions that you shouldn't lose points just because you spend time doing difficult problems. Neither of them can be perfect in the end. After checking, try the questions that you can't do.
5. The neatness of handwriting is the key to the teacher's impression.
