First, the proposal of open teaching methods.
We are in an era of knowledge economy, and a new and open society needs open teaching methods. The classroom is the main place for students to study. We should grasp the importance of classroom teaching to education and students' development, break the shackles of traditional teaching and actively realize open teaching. The innovation and reform of education cannot be realized in a short time. Teaching reform in some schools is still superficial, teachers' educational ideas are still outdated and backward, and students lack the conditions for free play, which affects their creativity. Therefore, it is an important task for teachers to seriously implement open teaching.
Second, the principle of open teaching method
1. Teachers should leave time and space for students to think independently, encourage students to show their individuality and guide students to develop their thinking ability. When solving mathematical problems, we should get rid of the shackles of answers and questions. Teachers should guide students to master mathematics content in different ways, realize the diversification of teaching methods, encourage students to think in many ways, and cultivate students' openness and criticism in an all-round way.
2. The principle of cooperation. Cooperation pays attention to the interaction between teachers and students, and group cooperative teaching is common in open teaching. We actively encourage communication between teachers and students, because through communication, discussion and debate, teachers can better understand students and help them understand and solve problems. The mutual communication between teachers and students can also show mutual respect and enhance the distance between teachers and students. In modern teaching, we should advocate cooperative teaching.
3. Subjectivity principle. The new curriculum reform requires giving full play to students' subjectivity. Students are the main body of classroom teaching, and each of them has his own characteristics, different personalities and different abilities. Teachers should teach students in accordance with their aptitude and attach importance to the independence of students, so that every student can be valued and cultivated. Only when students' initiative is brought into play can they have enthusiasm for learning and learn mathematics well.
4. Principles of life. Pupils are curious and interested in new things around them. Mathematical knowledge is closely related to our daily life. Through life-oriented teaching, students' interest can be stimulated, their ability to solve practical problems can be improved, and students can learn, feel and apply mathematics in life. Teachers should look for mathematics textbooks in real life and make students fall in love with mathematics and like learning mathematics through various teaching activities.
Third, open classroom teaching.
1. Open the teaching content. In the process of implementing the new curriculum reform, teachers must fully understand the connotation of the new curriculum reform and participate in teaching according to the concept of the new curriculum reform. Textbooks are the key items in classroom teaching and the main basis for teachers' teaching. However, all the contents in the textbook cannot be told mechanically. It is necessary to link the contents of textbooks with real life in a targeted manner, so that textbooks can be alive and alive. This teaching method is helpful for students to get close to mathematics and feel the fun of mathematics. Primary school mathematics is mainly some basic knowledge, which is not very difficult for students to learn, but the content is boring and students are easy to lose interest. In order to solve this problem, we should pay more attention to the practicality of mathematics education, so that students can adapt to the needs of life in the process of learning mathematics. In addition to the content in the textbook, we can also add some extra-curricular knowledge, trying to make students better integrate into society and obtain more scientific and updated mathematical information. This requires teachers to scientifically integrate teaching materials and realize teaching material innovation. For example, after teaching the four operations, you can simulate the real trading situation in class and ask students to fill in the invoice information; After calculating the study area, students can calculate the areas of classrooms and playgrounds. In this way, the teaching class becomes more active and students become more active, which not only makes them realize the connection between mathematics and real life, but also enriches their imagination, develops their personality and improves their practical application ability.
2. Create a democratic and open classroom. It is the bounden duty of teachers to pay attention to the development of each student. We should carefully prepare lessons, carefully design teaching contents, and care for every student from the heart, so that they can be lively and healthy in class. Through inquiry teaching, students can find and solve problems more easily, develop the ability of independent thinking, and show better ability when paying attention to and solving other problems. Only in an open teaching atmosphere can students feel the joy of learning mathematics, at least knowing that mathematics is not boring. Through inquiry-based open teaching, students can change from passive learning to active learning, make them think that "I want to learn" is the correct attitude, and then actively participate in learning and experience mathematics in personal practice. A free, open, active and relaxed teaching environment is conducive to communication between students and between teachers and students. They express their opinions, seek better learning methods, and constantly improve their math ability and develop themselves.
3. Design open exercises. In primary school mathematics, exercise teaching is an important link, which can help students to review the past and gain new knowledge. However, the open-ended examination questions have strong openness and flexibility, which can stimulate students' thinking more easily and make students' thinking range wider. Through open exercise teaching, it is of great significance to diversify the original unchangeable exercise mode, which is of great significance to stimulate students' innovative ability and cultivate their innovative consciousness. For example, when learning geometric figures, we can arrange some topics for students to collect all kinds of geometric figures, analyze the functions of various figures in life, let students feel the stability of triangles, and then analyze the uses of circles, diamonds, squares, trapezoid and rectangles in life.
4. Open teaching evaluation. Reasonable evaluation is helpful to improve students' self-confidence and let them know themselves better. The evaluation of open teaching attaches importance to the evaluation of students' learning attitude, learning process and the comparison results between the past and the present. We can also make students, teachers and students understand each other through self-evaluation and mutual evaluation, from the outside to the inside, from the form to the essence, find a breakthrough, and guide students to learn to listen carefully to others, understand others, cooperate with each other, and constantly criticize and reflect on their own and others' views.
Four. conclusion
To cultivate students' comprehensive ability, we must start with teaching reform, reform mathematics classroom teaching, create an open teaching situation for students and implement diversified teaching methods. Only in this way can students find and ask questions in open learning activities and master more mathematics knowledge in classroom learning.
