How to improve the effectiveness of high school math homework

I. Selected content, well-designed?

How to reform the traditional math homework. The key lies in eliminating the drawbacks, breaking the single, boring sea of questions type of homework mode, re-constructing a knowledge and ability, theory and practice organic combination, students are happy to accept the mode of homework. This mode of operation in line with the requirements of the new curriculum syllabus, is conducive to the development of the personality of secondary school students and ability to improve. Specifically, the following points should be grasped:

1, the content of the homework concise

Teaching practice shows that: one of the direct factors of the excessive burden of classroom work is the "sea of questions" flooded into the disaster, the root cause of this situation lies in the classroom efficiency is low, and homework Poor quality and quantity, lack of typicality. Attention should be paid to the "quality" of math homework, homework should be carefully screened in conjunction with the content of the classroom, and try to take into account the typicality, systematicity and comprehensiveness of homework. The selection of homework takes into account the principle of gradual progress from easy to difficult, and also pays attention to the principle of inspiration and consolidation. Along with the deepening of the new curriculum, the design of mathematics homework should also be innovative, to inherit and carry forward the advantages of traditional mathematics homework with a critical eye, abandon its difficult, complicated, biased, the old drawbacks, in order to student development for the purpose of this guiding ideology, we set up a group of teachers *** with the discussion, careful selection of the topic, the design of the most suitable for the students of the school-based homework, and get a good result.

2, diversified forms of homework

Traditional math homework are arranged for the written answer type of homework, monotonous homework to make the students feel bored, reducing the enthusiasm of students to do homework, but also not conducive to the exercise and training of students in a variety of skills. Therefore, it is important to pay attention to changes in the form of homework to achieve diversification of the form of homework, so that students can experience the fun of mathematics and feel happy from a variety of homework, so as to cultivate students' interest in mathematics homework, and then cultivate interest in mathematics. According to Polya, a mathematics educator, "Instead of being poorly equipped to cope with tedious mathematical content and an excessive number of topics, a responsible teacher should appropriately choose certain meaningful but less complicated topics to help students discover various aspects of the topic, and in the process of guiding students in solving the problems, improve their talent and reasoning ability." Effective homework means fully embodying the fun, autonomy, practicability, cooperation and openness of homework. Teachers should be based on the content of teaching and the actual situation of student learning, targeted to decide whether to set homework, how much should be set up, set up what kind of homework, never the same old thing. Both oral and written; both only students need to observe, think, discuss, but also need students to operate personally; both the knowledge of the literacy, application, but also the ability to training, training, to a variety of forms of reasonable combination, appropriate collocation.

In the scientific arrangement of homework at the same time, but also pay attention to the homework to cultivate students' interest in learning as well as creative consciousness and creative ability. Because interest is the driving force of student learning, in this regard, I think that as much as possible to make the homework questions can be close to real life, so that students can complete the homework at the same time to some of the knowledge of life to inspire the enthusiasm of students to learn; in addition to assigning homework should be adept at the topic to give play to the students to explore the value of a problem, a problem, a problem, a problem, in order to cultivate the students learn to understand, study the problem from a multilevel, a wide range of perspectives, A full range of understanding, research problems, cultivate students' sense of innovation and creative ability.

3, homework layout hierarchical

Today's education has the basic elements of subjectivity, individuality, basicity and development. Among them, the subjectivity and developmental requirements of homework must be hierarchical, in order to be suitable for all students, in order to meet the knowledge base is different, the intellectual factors of each student's needs.

To be based on the reality of all students, divided into levels, according to the person set the question. All students must do the basic questions, comprehensive questions to achieve the basic requirements of teaching, especially in the basic questions to emphasize the students' understanding of the basic concepts, the basic mathematical methods of thought, and the basic ability to include arithmetic, logical reasoning ability, spatial imagination ability training. Homework should also have "optional" open-ended questions for students with the ability to improve their training. That is, to ensure that the foundation of the better students "eat enough", but also to ensure that the foundation of the weaker students "can eat". In this way, both to consolidate and improve the effect of classroom teaching, but not to increase the burden of homework on students.

The same problem as much as possible to ask questions from multiple angles. The gradient of the questioning from easy to difficult, so that the students step on the ladder step by step to explore, so that each student can get a different degree of success to try. The multi-gradient nature of the questioning can help students to explore all aspects of the problem, to achieve a deep understanding of the nature of the problem, so as to cultivate the depth of thinking.

Designing ladder-type question sets. According to the needs of the teaching content, selected topics of different levels, from easy to difficult, according to the different ability requirements organized into groups of questions, targeted to set up the knowledge, methods, ability of the latest development zone, so that the students' thinking gradient step by step, just right. Let the students solve each problem, can personally experience the laws contained therein, appreciate the mood of the solution and the proposition of the idea. After these several methods of stratification of homework processing, to improve the enthusiasm of students to do their homework is practical and effective.

Second, the evaluation of homework and feedback?

Correcting assignments is an important and indispensable part of teaching, it is a silent "dialog" between teachers and students, through this "dialog" teachers can get feedback from the teaching and learning information, to understand the degree of mastery of the content of the students, but also to adjust the progress of teaching content. The teacher can get feedback on teaching and learning through this "dialog" to understand the degree of mastery of the content, but also to adjust the progress of the teaching content, students can understand the degree of mastery of the content from the homework test, so as to determine their own learning objectives and improve the learning method.

There are a lot of reforms in the method of homework correction: ① on-site correction; ② face-to-face correction; ③ students face-to-face correction, etc., but I think that as long as the feedback in a timely manner, we can improve the effectiveness of the homework. The so-called "strike while the iron is hot" can also illustrate this problem, can not put the feedback of homework delayed, if it is too late, some students may have forgotten their own classroom assignments, and even forget to do what questions, forget how they do, when they get the teacher to correct down the homework, and then have to remember to do their homework situation!

After the student's work to write a comment, the language should be extremely emotional, to convince people, both contain the teacher's true feelings for the students, but also has a certain target. Perhaps a simple comment will produce a strong shock in the minds of students, producing good learning results. For example, if you make a mistake in your homework, don't just say "╳", but say something like, "Look at page ╳ of the textbook and then do this question. You can also make appropriate comments such as: "Look at page ╳ of the textbook and do this question again?", "Read the question again carefully", "The solution is wonderful!", "Innovative". The teacher in the process of homework evaluation. Teachers in the process of homework evaluation, not only to correct the students' work in the right and wrong and give homework grades, but also focus on silent communication with students, which will achieve twice the result with half the effort.

Third, reflection on homework

The essence of math homework is "practice" and "reflection", and the deeper the reflection, the more sophisticated the practice can be. Therefore, whether all students can make each math homework to reflect y, and gradually develop a good habit of self-examination, self-reflection, is the key to the effectiveness of math homework.

This aspect includes both students and teachers. After the workbook is fed back to students in a timely manner, teachers require students to write out the reasons for their mistakes before revising. First of all, we know that in the correction of the ground, students have seen where they are wrong, but at this time many students only roughly understand where they are wrong, and can not really understand, of course, there are a small number of students then know. Before revising, to write the reason, then students will have to analyze their own mistakes, they will have to look at the same seat for them to have crossed out the error, think about the reasons, and write the reasons, so that you can summarize the reasons, to avoid not knowing where the error is, blindly revised. Secondly, what is the purpose of writing the correct answer next to each question? To give the student a guiding direction, so that he knows that he revised in the end right or wrong, and the correct result of a comparison will know, help a revision success. Two points in the wrong place to deal with so that students can have a goal to follow, otherwise some students may be revised again and again wrong, and even some students do not know where the error, will not be revised, etc., will go to copy other people's work or blindly write. Attention to focus on students to write the essence of the reason, such as "I counted the wrong", "I wrote the wrong" is not enough, should be written specifically where I am wrong, there are words, then long, no words, then short, but must write the essence of the place. After the students revised submitted to the teacher, the teacher carefully review the student's revisions, the student's error where to look carefully, students write the reason to look carefully, to see if the students really know their own mistakes, and then deal with: did not find out the reason, or revised incorrectly, not all returned to re-revise the reasons for writing. Because the students have the correct answer, so be careful not to appear "outside the gold and jade, the failure in the" phenomenon. At this point, the teacher will have to think y about the success and failure of their own teaching, summarize the experience and make up for the shortcomings. Practice has proved that the arrangement of math homework is not in the "more", but in the "fine". Teachers arrange appropriate, appropriate amount of effective homework can stimulate students' interest in learning, consolidate and improve students' learning effectiveness. Therefore, it is necessary to reform the traditional way of arranging math homework to make it artistic and diversified, so that students are willing to do their homework, turn passive into active, cultivate students' abilities in all aspects, and improve learning efficiency. Improve the effectiveness of homework, with innovative ideas, innovative means, innovative approaches, so that the right amount of homework exercises to maximize the potential of students, so that students will put more energy into activities with the cultivation of the spirit of innovation, practical ability.
