First, teachers should be lively and interesting, create a democratic classroom atmosphere, create an independent learning environment, and make students willing to talk to teachers.
I remember last semester I had the privilege of listening to a class given by Liu Song, a special-grade teacher. I still clearly remember the winning strategy. His lively and interesting teaching process can firmly attract the attention of people in the living place, so that every student feels that listening to his lectures is a kind of enjoyment, and learning and acquiring knowledge in the process of enjoyment. As Liu Song said, as long as you speak well in class, you can conquer all the students, make them like you, and concentrate all the students' attention on the class, thus improving their learning efficiency. Teachers can introduce vivid scenes and humorous stories in class, visualize abstract problems and make boring learning interesting! In addition, teachers should have the demeanor of the host in class, be natural and generous, smile and be humorous, so that students can learn in a harmonious atmosphere. Only students who "learn from" can "channel" Students like teachers, and they will also be interested in the subject where the teacher is, and then fantasize about creating something in this subject field. The classroom teachers advocated now should step down from the sacred platform, fully integrate with the students, eliminate the gap between teachers and students, create a good classroom atmosphere, and mobilize the enthusiasm and initiative of students to participate in the discussion. Only by establishing a good relationship between teachers and students and creating a relaxed, happy and harmonious learning environment for students can the efficiency of classroom teaching be greatly improved.
Second, the teaching objectives are clear.
Teaching goal is the general expression of students' expected learning results, and it is the result of the change of learners' behavior or knowledge, skills and attitude after learning a certain course, as described by American scholar Bloom in his teaching theory. It is the soul of target teaching and dominates the whole teaching activities. On the one hand, it is the starting point and orientation of teaching, and plays an important role in pointing out the direction, guiding the track and stipulating the results in the teaching process. So when preparing lessons, we should focus on these goals. In mathematics teaching, through the joint efforts of teachers and students, students can achieve the predetermined goals in knowledge, ability, skills, psychology, ideology and morality, so as to improve their comprehensive quality. On the other hand, the teaching goal is the end and standard of teaching. For example, when I was teaching mathematics in the fourth grade of primary school, I simply calculated the laws of addition and association in the second lesson. First of all, let every student know that the learning goal of this class is to make the calculation simple by using the algorithm, so that every time you come up with a problem, students should first think about how to make it simple, so that the teaching goal of this class runs through the whole class, and teachers and students can easily achieve the teaching goal.
Third, effective dialogue can highlight key points and resolve difficulties.
Every class should have a key point, and the whole teaching is gradually carried out around this key point. In order to make students clear about the key points and difficulties of this class, teachers can simply write these contents on the corner of the blackboard at the beginning of the class to attract students' attention. The key content of the lecture is the climax of the whole class. Teachers should stimulate students' brains by changing audio, dialogue, gestures, blackboard writing, application models, projectors and other visual AIDS, so as to make students excited, impress what they have learned in their brains, stimulate students' interest in learning and improve their ability to accept new knowledge. In order to ensure and promote effective dialogue, teachers should pay attention to learning objectives. If teachers only pay attention to the superficial features of students' dialogue, but not to the learning objectives, then the dialogue atmosphere in the classroom may be very warm and the number of dialogues may be large, but no real learning has taken place. This kind of dialogue may be jumping from one point to another, and it can't produce a whole and consistent understanding of the whole dialogue. Therefore, teachers should first put forward clear classroom learning objectives, and ask themselves from time to time: "What are the key concepts I hope students learn in this class", "What are the main points I hope they master" and so on. In order to realize effective dialogue, teachers must consider these issues in advance. The current curriculum reform emphasizes the combination of preset goals and generated goals, and the author is by no means opposed here. Whether it is a preset goal or a generated goal, in a certain dialogue process, it must be carried out around a specific goal, so at last, it is necessary to examine the achievement of the goal.
Fourth, classroom teaching dialogue between teachers and students to promote modern teaching
With the rapid development of science and technology, three machines and one scene have entered the ordinary classroom. It is particularly important and urgent for teachers to master modern teaching methods, but this does not mean that the dialogue and communication between teachers and students is not important, but more important. Teachers' clever use of language can make it easier for students to master knowledge. The characteristics of modern teaching methods are: first, it can effectively increase the class capacity of each class, so that the original 45-minute content can be solved within 40 minutes, which requires teachers to better use language to grasp the learning content; The second is to reduce the workload of teachers writing on the blackboard, so that teachers can have the energy to explain examples in depth and improve the efficiency of explanation; Third, intuitive, easy to stimulate the interest of primary school students. Teachers can guide students to learn by talking with them, which is helpful to improve their learning initiative. Fourth, it is helpful to review and summarize what the whole class has learned. At the end of the class, the teacher guides the students to summarize the content of the class, the key points and difficulties of learning through language. At the same time, through the projector, the content will jump to the screen in an instant, so that students can further understand and master the content of this lesson.
Five, according to the specific content, choose appropriate teaching methods, pay attention to teaching skills.
Each class has its own teaching tasks and objectives. Teachers can use teaching methods flexibly with the changes of teaching content, teaching objects and teaching equipment. There are many methods of mathematics teaching. For new teaching, we often use teaching methods to impart new knowledge to students. You can also flexibly adopt various teaching methods such as speaking, reading guidance, homework and practice in combination with the classroom content. Sometimes, in a class, multiple teaching methods should be used at the same time. As the saying goes: "There is no fixed method in teaching, but it is important to get the right method". As long as it can stimulate students' interest in learning and improve their enthusiasm for learning, it will help to cultivate students' thinking ability and help them master and use what they have learned. This is a good teaching method. Each class has its own teaching tasks and objectives. Teachers can use teaching methods flexibly with the changes of teaching content, teaching objects and teaching equipment. There are many methods of mathematics teaching. You can also make full use of group discussion and group cooperation, and flexibly adopt various teaching methods such as heart-to-heart, reading guidance, homework and practice. Sometimes, in a class, multiple teaching methods should be used at the same time. As the saying goes: "There is no fixed method in teaching, but it is important to get the right method". As long as it can stimulate students' interest in learning and improve their enthusiasm for learning, it will help to cultivate students' thinking ability and help them master and use what they have learned. This is a good teaching method. The application of various teaching methods serves certain teaching tasks. Teachers use appropriate teaching methods to teach, students will be interested in learning, easy to accept and will receive good results.
Six, the performance of students in the classroom, should be timely summary, give appropriate encouragement.
In the teaching process, teachers should always know the students' mastery of the content through dialogue. For example, finish a concept and ask students to repeat it; After an example is finished, erase the solution and let the middle-level students perform on stage. At this time, teachers should affirm their performance in time through language, which will greatly improve students' interest and self-confidence. Sometimes, for students with poor foundation, that is, underachievers, we should be more concerned and considerate, talk to them more, and narrow the distance between students and teachers. They are willing to talk with their teachers. Usually, according to the differences of students' personalities, we should look for their bright spots and praise them in time. For example, we can ask them more questions, give them more opportunities to exercise, give them a successful experience, make them realize that as long as they study hard, their academic performance will be improved, and at the same time, we should cultivate their self-confidence, give them more opportunities to exercise, give them a successful experience, and make them realize that as long as they study hard, their academic performance will be improved, and cultivate their self-confidence.
Seven, do a good job in class summary
After a class, some students may not know what they have learned. At this time, they should make full use of language to summarize the classroom in time, emphasize the key content again, and more importantly, help students sort out their knowledge, so that students can better grasp the laws of knowledge and improve their learning ability. However, it is best to summarize the class by asking students, for example, designing questions like "What have you learned in this class" and "What are the questions you don't understand" to induce students to summarize the class content, which will be more impressive.
In short, the improvement of classroom efficiency requires the joint efforts of teachers and students, both of which are indispensable. In the teaching process, teachers should always adhere to the student-oriented, create conditions and atmosphere for students in all directions and through multiple channels, fully mobilize students' enthusiasm and initiative, stimulate students' imagination and creativity, develop students' divergent thinking, carry out appreciation education and innovative education, and strive to make the classroom full of vitality, let students enter the realm of happy learning, and effectively improve teaching efficiency.
