First, the review class should have a clear goal and carefully design the teaching situation.
Teaching goal is the soul of a class and plays an important role in the whole class. When determining the review goal of a review class, we should not only consider that the goal must be comprehensive, accurate and moderate, but also consider showing the certain artistry of the review goal. In the review class, teachers should organize teaching closely around the goal and guide students to learn with the goal in the review class. With directionality, students will not lose their way. Only by integrating vivid and interesting life elements into clear teaching objectives, strengthening the connection between mathematics and real life, carefully creating teaching situations and stimulating students' interest and initiative in learning can review classes be interesting and effective.
For example, in the lesson of "Two Numbers Multiply One Number" by the famous teacher Professor Zhu Leping, when introducing the review content, the following situation was created:
Read the following sentences from left to right and from right to left respectively.
Shanghai tap water comes from the sea;
Singers sing at home;
People have been to the Great Buddha Temple, which is bigger than others.
I laughed at the cat, and the kitten laughed at me.
After the students read the teacher's summary, this is a very wonderful language phenomenon! This linguistic phenomenon is related to the multiplication formula 12×42=24×2 1 in mathematics. 62× 13=3 1×26? Verification of vertical calculation of student column. 84× 12=2 1×48? Verification of Vertical Calculation of 26×93=39×62 Student Train ...
Teacher Zhu created such a teaching situation, which seems to make students constantly calculate and verify in the process of solving a certain mathematical problem or finding a certain mathematical law in this class, and successfully achieve and complete the teaching goal of "multiplying two digits by one digit" in this class. However, every student unconsciously accepted the learning task in a relaxed and happy atmosphere and enjoyed it. Isn't this what we learn from in our daily teaching?
As Mr. Zhu said, it is enough to carefully prepare several such classes in one semester, but it must be that the teaching teacher has made sufficient teaching preparations before class, carefully designed and planned the teaching situation with specific teaching objectives on the basis of collecting a large number of teaching materials, which is artistic and interesting to a certain extent, so that every student can naturally immerse and enjoy learning in a casual learning state.
Second, the review class should be good at excavating life materials and stimulating review interest.
According to the review goal, follow the new concept of curriculum reform, actively control the teaching materials, boldly reform the unreasonable factors in the teaching materials, rationally adjust the teaching materials, and replace the review questions in the teaching materials with mathematics questions that students are familiar with, interested in and close to life, so as to meet the actual needs of students and meet the teaching needs. Make students learn from feelings, review content, learn from interests, fully feel that mathematics is in their own lives in positive thinking and exchanges and cooperation, and then construct their own mathematical knowledge, making the structure of knowledge and ability more reasonable.
In the whole review process, students should not only be "listeners" and "bystanders", but also return the review opportunities to students, and stimulate students' interest in review through various strategies, so that students can complete the process of recalling, discussing, sorting out, communicating, summarizing and using themselves, so that students can truly become the masters of learning. To this end, we can also use group learning to form a competitive situation, and carry out activities such as math story meetings and learning competitions to attract students to participate in review. At the same time, students should be appreciated by various means in review. Encouraged appreciation can make students get psychological satisfaction and stimulate a stronger desire to participate.
For example, when I was explaining the lesson of "selecting statistical charts", I introduced it like this:
What kind of life and leisure do students like best?
Some say playing computer games, some say going out to climb mountains, and some say drawing. ...
Please tell me what kind you like best, and then we will make statistics and say why you like this kind of leisure best.
The students raised their hands to speak.
So what kind of statistical chart do you choose to describe the statistical results just now?
The students easily chose the pie chart.
Mathematics and the origin of life serve life in the end. Therefore, we should integrate the elements of life, tap the material of life, and be close to the reality of students' life. If he is interested, he will accept it; He can't accept people who are not interested. Therefore, teachers must attach importance to students' psychological activities in teaching activities. Interest is the intrinsic motivation for students to explore new knowledge. Students' thirst for knowledge can become stronger and stronger because of teachers' proper education, or they can be suffocated because of teachers' improper education. Through teaching experience, I really realized that students' needs are the first. Starting from the actual needs of students, we should create vivid and effective teaching situations, use correct methods, arouse students' interest in mathematics, fully mobilize students' enthusiasm for learning mathematics, and make students always take the initiative in the classroom to better achieve the purpose of education and teaching.
Third, the review class should try to make the teaching starting point low, face all, and take into account differences.
The mathematics curriculum standard clearly points out that the mathematics curriculum in compulsory education stage should be basic, universal and developmental, so that mathematics education can face all students. In order to make "different people get different development in mathematics", it is the principle to teach students in accordance with their aptitude, start from a low starting point and make overall plans. Put forward higher requirements for middle school students and encourage them to challenge flexible and difficult questions; For students with learning difficulties, we should appropriately reduce the difficulty, let them study through their own efforts or under the guidance of teachers, increase their self-confidence, promote them to experience success, and let students at all levels improve on the original basis. In the review process, we should fully reflect the teacher-led and student-centered teaching position. Only by actively participating in review can students understand and learn and develop. Professor Ye Lan 15 "Research on Theory and Practice of New Basic Education" concludes: "Teachers should not replace students in any learning task that students can accomplish through their own efforts, but should give them teaching tasks in a gradient, arrange students' resources in an orderly manner, and create a platform for students' independent development. In this respect, it is the basic soul of the new basic education teaching reform. Review class pays attention to every child, so that every student's potential can be discovered and developed. Therefore, teachers should try their best to leave space and time for students to ask questions, so as to ensure the efficiency of the review class.
For example, in the area calculation review class of plane graphics, the requirements for ordinary students are: to correctly calculate the area of plane graphics and know how these area formulas are derived. Higher requirements are put forward for top students: can you find the connection between these formulas for calculating the area of plane graphics? Fully stimulate students' desire to explore. After careful observation, thinking and discussion, they found that the area formulas of parallelogram, triangle and trapezoid are all derived from the rectangular area formula. This creative conclusion makes students excited, and then experience the joy of success again in review.
In short, a good review class is like a beautiful composition, which is scattered in form but not in spirit. It is rich in content and form, lively and reasonable in organization, which will greatly promote students to master mathematical knowledge, promote students' development, form mathematical skills, improve their application ability of mathematical knowledge and improve classroom teaching effect.
