How much mathematics knowledge students have learned inside and outside the school and how much they can apply are often measured by homework feedback. The quality of homework is an important way to measure students' intelligence and ability. In the usual teaching, I often find that some students are not very serious when they do their homework. They are careless, careless, perfunctory and smeared, and their writing is dirty and messy, and there are many mistakes. Sometimes I panic, either copying the wrong topic or writing the wrong symbol. In order to be quick, you don't have to do it by hand. Even if you do it by hand, you just grab a piece of paper, or simply do it on the cover of a book or exercise book, in the newspaper, or even on the table or in your hand, which makes it dazzling and difficult to identify. Sometimes even if calculus is right, copying it into exercise books is wrong. In view of these phenomena, I put forward a micro-topic "How to improve the quality of students' math homework", hoping to gain something through research.
Topic focus: How to improve the quality of students' math homework?
Research ideas:
1. Through investigation, we found the root of the poor quality of students' homework;
2. Explore ways to solve problems by reading the questions;
3. Solve problems through teaching, home visits and other activities;
4. Collect and summarize the research results.
Results outlook:
Show the research results through "teaching diary", "case analysis", "homework display" and "experience summary".
Research process:
In mathematics teaching, I am often angry with students for writing wrong exercise books, and I am often busy helping students to revise their exercise books. Not only I, but also many teachers feel this way. Sometimes it takes only ten minutes to teach a knowledge point in a class, but it often takes several times or even ten times to correct students' exercise books. You see: the mistakes in homework have just been analyzed collectively in class, but some students can't correct them; We had to have a second group counseling, but a small number of students were wrong after correcting them; No way, the rest of the students can only use their spare time to tutor one by one. This makes most teachers tend to "chase" students as soon as the bell rings, go straight to the classroom as soon as they put down their rice bowls at noon, and have to drag several students after school at night. They have their hands full all day. It can be said-"What are you busy with? Just to correct homework! " So how to improve the accuracy of students' math homework and the quality of writing, so as to reduce the workload of teachers? I have made some intentional explorations and attempts in teaching.
First, improve the operation strategy.
1, guarantee the running time.
In recent years, the wind of "reducing the burden" has swept across the land of China, and the mathematics syllabus clearly points out: "The homework time of middle and senior students should not exceed half an hour." To this end, I advocate the wind of "study hard and have fun" among students. Students are required to listen carefully, think positively and express their opinions enthusiastically in each class. The class will be over in about 30 minutes, and 5 to 10 minutes will be reserved for students to do their homework in each class. This not only ensures the time for students' homework, but also keeps abreast of students' learning situation, timely tutors poor students and reduces the probability of making mistakes.
2. Scientifically assign homework
Dozens of students in the class have different intelligence, different abilities and different foundations. When assigning homework, if it is the same, it will not show personality, and the homework will be too abstruse, which will hurt the confidence of middle and lower level students, make them feel afraid of mathematics because they can't taste the joy of success, and is not conducive to the teaching and transformation of poor students. Homework is too simple, but it is a waste for excellent students and will make their level stagnate. When assigning homework, how can we satisfy both excellent students and poor students? When assigning homework, I add a "daily question" on the basis of the required questions, such as: for students with poor foundation, add several basic questions to let them complete each homework, train from shallow to deep, let them taste the joy of success and become interested in mathematics; For students with excellent grades and quick thinking, add a few additional questions with certain difficulty to train their thinking.
3. Cultivate inspection habits
Cultivating students' habit of checking is something that every math teacher should do, but it is also a headache. Some questions are required to be tested, and students may deal with them formally, but if they are not required, they simply don't know if they have taken the test. How to cultivate students' inspection habits? I think we should start from the following aspects: 1, teaching inspection methods. Step one, read the topic and requirements again to see if the selected method meets the meaning of the topic; Step 2, check whether the numbers and operation symbols are copied incorrectly or omitted; Step 3, check whether the calculation sequence is wrong and the calculation result is correct. 2. Before I do my homework, I take pains to remind students that they must check. Over time, it will form a habit. 3, homework as far as possible face batch. Frequently spot-check students, let them tell the methods and steps of inspection, and "force" students to check their homework before correcting it. 4. After correcting the homework, ask the students to do the wrong questions again to strengthen the knowledge they have learned.
4. Clever use of incentives
Whenever we check our homework, we always find omissions and delays. What is the reason? Of course, it is common to forget to do it for a while. But I think the main reason is lack of interest in homework. How can we make students interested in the homework itself? When assigning homework, in addition to strengthening the interest of exercises, the most important thing is to use appropriate incentives to improve students' enthusiasm and initiative in doing homework. There are many ways to motivate. As soon as school started, I bought several small seals from the stationery store, which read "first-class", "good" and "progress". Those who do their homework correctly and well will be labeled as "first-class", and those who make greater progress will be labeled as "progress". Every time homework comes down, students will always whisper to each other about who got the "first class" and who got the "good". A week later, I will choose the three students who won the most seals and write their names on the bulletin board of the class with red chalk. Students who have been on the bulletin board three times in a row can also get a small prize from me. Therefore, a positive competitive atmosphere has been formed in the class. Students regard homework as a kind of competition and want to win the first place. The more neatly the fonts are written, the more beautiful the layout will be, and in order to get a "first class" every time, the students will pay more attention to the class.
5. Make good use of comment on writing
When correcting homework, you can add appropriate comments. Don't underestimate this little comment, it is very useful. On the one hand, it can better promote the communication between teachers and students. Talking is naturally the best way to communicate between people, but it takes a lot of energy to talk with dozens of classmates, so when correcting homework, adding one or two short sentences can also achieve this effect. For example, for students who are too quiet and shy, you can write, "You are very serious in class, but I have never heard the voice of your discussion with your classmates. I'm really looking forward to ... "; For students who like to fidget or talk in class, you can write "You are smart. I believe you will be better if you are more careful in class! " ; For careless students, write "look, it's wrong again." Pay attention next time! " ..... on the other hand, it can also play an incentive role. Writing comments such as "Your handwriting is really beautiful", "Keep improving, keep working hard" and "Your idea is really wonderful" in students' exercise books can effectively motivate students and make them interested in homework.
In fact, the purpose of assigning homework is to connect mathematics with real life, stimulate students' interest in learning mathematics through practical operation, feel the connection between mathematics and life, and make every student like learning mathematics and doing math homework, so as to develop in an all-round way in this paradise of math homework and really improve the quality of students' homework.
Second, cultivate habit strategies.
1, strict, temper students' will quality.
Calculation standard is the premise and guarantee of correct calculation. When solving problems, students are required to have a standardized calculation format, neat handwriting and neat homework paper. Draft is a necessary means of mathematical calculation, and many calculation errors are caused by messy drafts. I require students to have a special draft book with a unified format: the title number written in the draft book should correspond to the title number and topic in the exercise book one by one, and the handwriting should be neat and clear. The draft is stacked with the homework and can be used at any time. The standardization of draft questions, the seriousness of draft homework calculus and whether homework can be checked consciously often reflect students' attitude towards homework. If the students' calculus sketches can be as organized and standardized as writing, and check them consciously and carefully after the completion of homework, it will not only greatly improve the correct rate of practice, but also promote the students' habit of doing homework seriously.
For students, the formation of many good behavior habits needs a transformation process from passive to active, and in this transformation process, strict requirements are necessary. Mistakes in irregular calculation in homework must be corrected; If the writing is not neat, be sure to point it out in time and write it in the exercise book: "Write correctly, keep improving!" " "I believe you can write neatly!" Wait for short comments. Make a detailed comment on the common mistakes in the classroom, and tell the students about the repeated mistakes, so that students can check the implementation of the calculation specification and hand in the draft book together with the workbook for the implementation of the draft writing specification. I correct the draft as carefully as I correct my homework, and I also ask students to seriously correct the mistakes in the draft.
2. Combine home and school to cultivate students' sense of learning responsibility.
Nowadays, parents of one-child families are used to accompanying students. They go home to do their homework, parents read a question, tell a question, and students do a question, which makes children feel strongly dependent. There are also some students who often do their homework and then finish it. Examination is a matter for parents. Some parents point out directly when they see mistakes and how to correct them. Over time, children have developed the habit of not doing their homework seriously and waiting for their parents to check, so they can't take the initiative to check themselves during the exam. In view of this situation, I communicated with my parents in time and reached an understanding. In fact, the teacher asked parents to check their signatures in order to let them know whether their children's homework attitude is correct, whether they have done it according to the teacher's requirements, whether their writing is correct and whether the papers are neat. As for whether it is correct or not, parents only need to tell their children that there are mistakes in today's homework and which questions need their children to take the initiative to find. He found these problems and corrected them in time. Parents should not be stingy with praise and encouragement. Therefore, it is very important to understand the basic usage of arithmetic and cultivate serious homework habits by teaching students to read, examine and analyze the quantitative relationship. We should not only solve practical problems, but also do calculation problems and conceptual problems. For example, students are required to look at the problem, see the operation symbols clearly, and analyze the calculation data to see if there is a simple method; Then determine the operation order and start the calculation. This seems to be just a cultivation of computing habits, but it actually includes the training of thinking order and flexibility.
3. Positive evaluation to stimulate students' interest in learning.
Interest is the driving force of learning. Only when students feel interested can the whole learning process be a positive and relaxed process. After each calculation result comes out, it is very necessary to check and check. Encourage students to be patient and meticulous when checking. They should first check the original question to see if there are any mistakes in copying data or operation symbols, then see if there are any mistakes in the sequence and calculation of each step in the calculation process, and finally see if the result is correct. You can also check whether the calculation is correct by checking or estimating. I give different incentive mechanisms to students with different work levels. Some students wrote, "You have made progress!" "Great progress, I hope to continue to work hard!" ""the words are getting more and more correct and beautiful! " "Great!" Encouraging comments like that. For homework with correct calculation, standard format and neat handwriting, put a few red stars or give an "apple" ... to make students' homework writing and quality better and better.
I often let students appreciate the excellent homework in the class and show them the improved homework. At the same time, I asked him to introduce why he had made such great progress and told other students to learn from them. Excellent homework and improved homework are evaluated once a week, and summarized and rewarded once a month. Of course, the evaluation criteria have been formulated before: (1) You must finish your homework independently and not copy it. (2) Finish the homework on time and in quantity. (3) The operation accuracy is high. (4) Homework handwriting is neat.
In addition, the differences between students are objective. Some students (especially those with learning difficulties) work hard and make mistakes. Therefore, treating different students with the same standard sometimes makes some students find it difficult and will dampen their positive heart. Therefore, the requirements for these students (students with learning difficulties) can be reduced. In this way, most students will consciously write clearly and check when doing their homework. Stimulated students' interest in learning and improved the quality of homework.
As we all know, it is a long and complicated process to cultivate students' good homework habits. Teachers should take corresponding measures to cultivate these habits in time according to the development of students, so as to provide good conditions for improving the quality of students' homework and developing their psychology.
Yan Yuan, an educator in the Qing Dynasty, said: "Words have limited contribution, but Xi has no contribution." In the process of mathematics teaching, we should not only pay attention to the teaching of classroom knowledge, but also pay attention to "the merits of practice". In a word, it is not easy to improve the quality of students' homework. We need every teacher to spend time, energy, attention to details and pay more hard work, so that the quality of students' math homework can keep up with the pace of the new curriculum reform!
