First, the theoretical basis for the effective design of junior high school math homework
How to judge whether the work is effective? Domestic research is often measured from the following aspects: whether we can grasp the positioning of teaching content; Whether to attach importance to individual differences; Whether to let students actively participate in the process of completing homework; Whether the homework can reflect the requirements of interaction and whether teachers and students participate together; Whether to link homework with students' classroom learning; Whether to pay attention to developing learners' cognitive skills and improving learners' quality.
Second, improve the effectiveness of junior high school math homework practice
To improve the efficiency of junior high school mathematics learning, homework design should be scientific and reasonable. Teachers can get twice the result with half the effort by preparing materials, studying the main contents of curriculum standards, carefully designing typical exercises, highlighting the key points of knowledge and infiltrating mathematical thinking methods.
1, job layout
(1) Select homework questions to reduce students' burden and increase efficiency. Mathematics learning is a step-by-step process. Every assignment should be based on students' actual level and classroom teaching objectives, and appropriate topics should be selected from textbooks or extracurricular exercises. For example, if the goal of teaching is to learn the division with the same base power, we should choose exercises closely related to the division with the same base power as homework, and we can't simply arrange a large number of simple and repeated exercises by practicing skills; Don't rush for success, arrange some exercises that need to be converted into same base powers and subdivided as homework; For some topics that are too comprehensive and far from the actual level of students, we should boldly give up or postpone them. Choosing homework topics can not only cultivate students' ability step by step, but also help to improve students' homework efficiency. Because students' homework is not much, but detailed, it is more practical for children who are currently immersed in homework.
(2) The assignments should be graded. The so-called hierarchy means that each homework problem is deep and shallow. According to the composition of each homework, some improvement problems are arranged for each homework in a planned and step-by-step manner, leaving room for students with spare capacity to make progress.
Step 2 finish your homework
(1) Criteria for completing the operation. Because the completion of homework is the core of the homework process and the key to the effectiveness of homework, it is necessary to put forward the standards that homework should meet to students, which is an effective means to control the quantity and quality of students' homework.
Without necessary standards and requirements, students' homework will be in a state of laissez-faire, students will show slack and sloppy coping behavior, and the effect of homework will naturally decrease. Therefore, the design of mathematics homework should consider the individual differences of students, pay attention to each student, and design different levels of homework according to each student's cognitive characteristics. The arrangement is from easy to difficult, step by step, so that students can choose according to different needs. Students with learning difficulties can do basic and imitative homework and design a ladder for their success, so that these students can succeed; For students who have spare capacity for learning, they can do extended, exploratory and open homework. Through thoughtful and creative homework, they can grasp the key features of concepts, deepen their understanding and application of mathematical knowledge, and cultivate their sense of inquiry and innovative spirit. Through the stratification of mathematics homework, students' weariness of learning can be effectively overcome, students' interest in learning mathematics can be improved, students can feel the necessity of homework, stimulate their learning motivation and curiosity, cultivate their curiosity, gradually improve their learning ability and improve their academic performance.
(2) Monitoring and guidance of operation progress. Monitoring and guiding the progress of students' homework is an important condition to improve the effectiveness of students' homework. Teachers should require students to finish their homework within the specified time, and can regularly check the progress of students' homework, find problems in homework in time, and make appropriate corrections and guidance. During the work of the class teacher, he should often walk around the classroom, communicate with the students individually and give individual counseling. If teachers regularly monitor the progress of students' homework, and give further guidance to homework when necessary, such as helping students to clarify the nature of homework problems and putting forward ideas, strategies and methods to solve homework, the effect of students' homework will be greatly improved.
3, homework correction
Correcting homework is an indispensable and important link in teaching. It is a silent "dialogue" between teachers and students. Through this kind of "dialogue", teachers can get information feedback from teaching and learning, understand students' mastery of what they have learned, and help to adjust the progress of teaching content; Students can know their mastery of what they have learned from the homework test, so as to determine their learning goals and improve their learning methods. There are many reforms in the methods of correcting homework, such as classroom correction, personal correction and students' personal correction. But as it turns out, only the teacher can correct it himself is the most effective.
4, homework feedback
Teachers correct homework, some teachers give feedback every other class, some give feedback on the same day, and some even give feedback the next day. Is the feedback always the same? We might as well reform and innovate this feedback method to make the feedback more timely. Facts have proved that only timely feedback can improve the effectiveness of the operation.
When the teacher finished the homework evaluation in time, the feedback was not over yet. It is also necessary to guide students to collect wrong questions in time and copy them into their own "wrong question set". Teachers should think deeply about the success or failure of their own teaching, sum up experience and make up for the shortcomings through the problems reflected in these collections.
In a word, to improve the effectiveness of math homework can no longer be the traditional arrangement, completion and correction of homework, but the cognitive process of changing students' learning style, so that students can actively participate in acquiring knowledge and solving problems. The effectiveness of mathematics homework is an important way to improve the effectiveness of teaching. Teachers should design math homework reasonably and scientifically and give full play to the function of homework, which can not only reduce students' heavy homework burden, but also enable students to better master knowledge and skills, form an attitude of being willing to explore, liberate students from homework, truly implement and embody the requirements of quality education and improve the effectiveness of teaching.
