How to strengthen the timeliness of the classroom

This year is the eighth year of the implementation of the new curriculum reform in Shandong. In the past eight years, I have made great progress in teaching and basically formed my own teaching system, but there are still some shortcomings. For example, sometimes the classroom efficiency is not high, resulting in teaching tasks can not be completed on time. To improve the timeliness of the classroom, we must first find out the reasons that lead to the inefficiency of the classroom in teaching, and then prescribe the right medicine. Take measures to make up for it. First of all, let me talk about several reasons that lead to the inefficiency of classroom teaching: 1, the understanding of teaching materials is not in place, too superficial. If teachers can't fully and profoundly understand and grasp the teaching materials, can't figure out the ins and outs of mathematics knowledge, and can't grasp the writing intention of mathematics teaching materials, then it is certain that the teaching plan designed in this way will inevitably greatly reduce the effectiveness of classroom teaching. 2. Simplify the teaching process. As we all know, college entrance examination not only examines students' mastery and application of basic knowledge, but also examines students' flexible thinking ability. Most of the topics involve multiple knowledge points, and some methods are difficult to think about. If teachers only teach students textbook knowledge and some simple methods in teaching, students' ability and thinking will not be effectively improved and developed. Students can't adapt to the difficulty of the college entrance examination questions. 3. The classroom atmosphere is dull and there is little interaction between teachers and students. If teachers do not pay attention to guiding students to participate in teaching, there is no way to stimulate students' interest in learning and cultivate students' active learning methods. Over time, students will learn passively and their grades will get worse and worse. 4. Students have poor study habits, lack of learning methods, and have no good habits of asking questions, previewing and reviewing. For example, classes. Passive lectures. Although you can understand the class without previewing, you can only know what is difficult and what is important after previewing. The task after class is too simple. Learning mathematics is by no means to improve students' thinking ability by doing a few questions. Some teachers are still used to arranging several topics after class as an extension of mathematics classroom teaching. Doing some after-class questions can consolidate the knowledge learned in class that day and practice certain skills. But it is not enough to be satisfied with this. Simple repetition and imitation of classroom materials will only cause students' inertia and hinder the continuous development of their thinking. It can be seen that it is very necessary to arrange and implement diversified after-school learning tasks. For the above reasons, I think the following measures must be taken to improve classroom efficiency: 1. Careful preparation of lessons is a powerful guarantee to improve classroom efficiency. The key to the efficiency of classroom teaching is preparing lessons. Preparing lessons is the basis of teaching, and preparing lessons is fundamental. What is the knowledge structure of this course, what are the key points and difficulties, and how to break through? Only when you have a clear understanding can you be handy when giving lectures, and the efficiency will naturally be high. If you don't prepare lessons well, you will stumble, the weight will be unbalanced and the efficiency will naturally be low. Teachers should be full of passion in class. Some teachers have to adjust their mood in class, while others are listless and speak slowly. After a long time, the students were infected and depressed, and the teacher's lecture became a lullaby. The efficiency of natural classroom is low, and it is difficult to improve the grades. On the contrary, those teachers who are forceful and passionate in class, because of emotional contagion people, generally get good grades. 3. The introduction of new lessons should be concise, straight to the point, and don't go too far. Some teachers spend a lot of time reviewing the previous content and even explaining it until the beginning of a new class. Some teachers set up too many situations and delayed for a long time. The introduction of new courses should be simple, not complicated, and come straight to the point. 4. Give full play to students' main role. Teachers should skillfully design situations, set questions, stimulate students' interest in learning, and let students actively participate in the teaching process, so as to get twice the result with half the effort. If students' experience and feelings are ignored, language and eye contact are not maintained, and students' enthusiasm is not mobilized in the teaching process. 5. Strengthen the organization and management of students in the teaching process. Good organization and management in the teaching process is an important guarantee to improve efficiency. The teacher said on the platform that students fighting, talking, reading novels and playing mobile phones below will not be efficient in class. Teachers should deal with this phenomenon in time; When students discuss in groups, students can't stop while discussing, and teachers should stop it in time; Students get stuck in answering questions, speak slowly and stop in time. 6. Using a variety of teaching methods, especially the clever use of multimedia teaching methods or means, it is easy to make students feel tired and distracted. This requires us to take various methods to attract students' attention. Multimedia teaching can increase classroom capacity, save blackboard writing time, and intuitively arouse students' interest in learning. It plays a vital role in improving classroom efficiency. So I suggest you use it often. 7. Establish a harmonious relationship between teachers and students. Only when most students like a teacher will they like his class, concentrate their attention and be active in thinking. If students are genuinely bored with you, no matter how well you speak, they will not listen, and there is no way to talk about classroom efficiency. Therefore, teachers should pay attention to appearance, shape a good personality, care about students and make friends with them sincerely. Communicate with them more, make students like you, and the classroom efficiency will be greatly improved. 8. Create a "low-pressure, high-challenge" classroom atmosphere. For students, this kind of atmosphere makes them relax and know that the teacher will always help them. Students are more willing to ask and answer questions, and will not feel the pressure from teachers and other students, and feel safe and respected. Teachers should constantly set questions for students and constantly convey expectations to students. Lead students to overcome difficult problems. 9. Actively guide teaching, listen to the lessons in the old classroom and learn from its excellent teaching experience. If teachers let students learn by themselves for a long time in class, the classroom efficiency will not be very high. Teachers should not stick to textbooks, process the textbook knowledge before passing it on to students, and constantly give students specific instructions to guide their learning activities. Only in this way can a class complete more learning tasks. In addition, by listening to the class evaluation, we can know the shortcomings, which is convenient for improving the teaching plan and improving the classroom efficiency as much as possible. In addition, whether the teaching objectives are specific and clear, whether the selected cases are typical, whether the language is concise, and whether the blackboard writing is clearly summarized. It also has an important impact on classroom efficiency. In a word, there are still many aspects to be studied to improve the classroom teaching efficiency of senior high school mathematics, but the most crucial thing is the teacher.
