Bacon said: "habit is a tenacious force, it can dominate life!" " Due to different habits,

It either makes a person or destroys a person. "Obviously, it is very important and necessary to form good habits." The Mathematics Curriculum Standard points out that in order for students to learn valuable mathematics, and to bring questions and ideas into the mathematics classroom, in fact, this requires students to preview before class. Pre-class preparation refers to students' independent learning of new content before learning new lessons, which is the prelude and overture of classroom teaching. Preview on the basis of students' cognitive level and existing knowledge and experience can stimulate students' enthusiasm for learning, provide them with opportunities to fully engage in mathematical activities, help them understand and master basic mathematical knowledge, skills, mathematical ideas and methods in the process of independent exploration, and gain rich experience in mathematical activities. Cultivating students' habit of previewing before math class is also the premise of constructing "students' active learning classroom" teaching mode under the new curriculum reform. Therefore, teachers, as organizers, guides and collaborators of mathematics learning, should cultivate students' good habits of preparing lessons in mathematics, teach them correct methods of preparing lessons in mathematics, make them actively and consciously participate in the whole process of mathematics teaching, and finally become people with strong self-learning ability and innovative spirit. Personally, I think that if we want to cultivate the habit of previewing math classes for primary school students, we should start from the following aspects:

First, change ideas and attach importance to preview.

First of all, teachers should attach importance to students' preview, and don't think that students will not experience the confused, operational, comparative, analytical and comprehensive thinking process with teachers and taste the satisfaction and pleasure of exploring success together. Because preview is the process of students' independent participation and acquisition of knowledge, and it is one of the important ways to cultivate students' independent learning and improve their self-learning ability. Wei Shusheng, a famous educator, once said: "Students can understand 99% of the textbooks through materials, and teachers only play the role of 1%." The ratio of 1% to 99% may be exaggerated, but at least it shows a truth: without a certain range of activities, people can't accomplish important things, and the sprout of children's autonomous learning consciousness and motivation must thrive in open learning activities, and the first step of autonomous learning is to learn to preview.

Secondly, teachers should also make students aware of the importance of preview. Teachers can not only tell students the benefits of preview in theory, but also infiltrate the important role of preview in specific mathematics learning activities, encourage students to preview mathematics, and make them gradually realize that the formation of preview habits is very important for their lifelong learning and development.

Second, stimulate interest and be willing to preview.

The curriculum standard states: # 8218; Interest is the best teacher for students. In order for students to have efficient learning methods and scientific learning attitudes, it is necessary to start from students' interests. Vivid, intuitive and interesting learning will stimulate students.

Summary of courseware teaching plan exercises in primary school grades one, two, three, four and five.

The desire to learn. #82 19; Preview this learning activity is no exception, it is an individual and conscious activity. To carry out this activity requires a strong interest in learning and correct learning motivation.

(1) Introduce #82 18 into preview activities; Competitive consciousness # 8219; . For example, once a week to carry out appraisal activities, selected several # 8218; Preview expert # 8219; (or # 8218; Preview Starlet # 8219; )。 You can also let students who have a particularly good preview be small teachers in the classroom and organize the reporting activities of the whole class. In this way, students will reflect on their own preview methods in the process of communication, learn from each other's strengths and improve their preview ability; In addition, students get a successful experience, which stimulates their interest in preview.

(2) Encourage students with inspiring language. For example, when assigning homework to students, say: # 8218; I think who is the little expert (or' little star') in the rehearsal! #82 19; When checking the preview effect, I found that the previewed classmates would give him comments in the preview book: # 8218; You are such a good thinking boy! #82 19; #82 18; The rehearsal was a success. Keep up the good work! #82 19; If you find that students have made progress, you should also praise them in time, such as # 8218; What a careful preview! Use your head more, and you can be a little teacher! #82 19; #82 18; Keep working hard, the teacher believes you can do it! #82 19; Wait a minute. In addition, well-prepared students can show their homework in the Taiwan Province experience, and the preview method can be told to students. Let students constantly experience success and build self-confidence.

(3) Establish an appropriate reward mechanism. Teachers can give appropriate rewards to students who have prepared well or made progress in preparation, and can also stimulate students' interest in preparation. Such as: reward them # 8218; Wisdom star # 8219; If you accumulate a certain amount, you can give them some prizes.

Third, teach it to fish and learn to preview.

1, reasonably arrange the preview content. When students begin to preview, they don't know where to start. At this time, teachers should design preview tasks, so that students can preview with tasks, so as to be targeted and targeted. This requires teachers to analyze their students' learning situation, combine the characteristics of teaching materials, carefully study relevant learning content, and put forward preview content that is both valuable and attractive and can arouse students' strong preview interest. The most important thing is that the content of the arrangement should be hierarchical, so that students can preview, think and solve problems.

Three levels of problems: students with learning difficulties only need to read carefully to know what we are going to learn in the next lesson and what it looks like; Most middle school students should think about why this level is like this. Top students should think about what they can do and whether there is a better way on the basis of two levels. For example, the preview content of "perimeter of rectangle" is arranged as follows: ① Talk about the characteristics of rectangle and understand the meaning of perimeter. ② Master at least one calculation method of rectangular perimeter. What is the circumference of a rectangle?
