How to efficiently prepare lessons for primary school mathematics
To realize efficient math class, we should do the following work well. 1. We know that the classroom without presupposition is laissez-faire, chaotic and inevitably inefficient. It is important to be efficient for 40 minutes. First of all, we should seriously study the new curriculum standard, which aims at the physical and mental characteristics of students of different ages. Scientific and specific provisions have been made for the teaching objectives of different classes. This requires us to study the standards carefully and do it in strict accordance with the requirements of the standards when formulating teaching objectives. First of all, the orientation of teaching objectives should be moderate and difficult. Just like playing basketball, if the basket is too high, students will naturally lose confidence. If the basket is too low, students will easily plunge into the basket, and of course there will be no joy in overcoming difficulties. Test paper test. Secondly, teachers should fully consider the unity of three-dimensional goals when formulating teaching goals. Knowledge and skills, emotional attitudes and values, processes and methods are equally important and indispensable. Thirdly, the formulation of teaching objectives should also consider three levels: good, medium and poor. The formulation of teaching objectives should also vary from person to person, and students at different levels should achieve different goals, so it is necessary to avoid generalizing. Efficiency is based on effectiveness, and efficient classroom begins with effective lesson preparation. Many teachers around us have been teaching for many years. They think they know everything without preparing lessons or even reading books. When they are in class, they can do whatever they want and go wherever they want. There is no goal at all. The result can be imagined. In fact, every year we meet different students and encounter different problems, so it is very important for us to prepare lessons. When preparing lessons, we should prepare teaching materials, students and teaching methods, and prepare several sets of different teaching materials for comparison, so as to choose a more suitable teaching content and method for students. When preparing lessons, we should make unit lesson plans and determine the teaching objectives, key points and difficulties. We should fully understand students' actual and ideological understanding, guide students to find out what they have learned related to the new course through preview, and do a good job in reviewing and consolidating. Only in this way can we be targeted. The more thorough the lesson preparation, the more detailed and scientific the lesson plan design, the more the "loss" in the classroom will be reduced, and the higher the classroom teaching efficiency will be. Education is "doing" rather than "saying". Whether it is Yang Si's "learning before teaching as classroom training", Dong Lu's lecture due to "taking the exam", and the appearance of efficient classroom marked by Du Langkou, they are all looking for and exploring ways and means of efficient classroom. Their exploration and practice made us suddenly realize that the simplest educational truth is actually not complicated. The key is to find a suitable starting point for our classroom teaching. The classroom teaching mode based on "tutorial system" focuses on the cultivation of students' ability and the "process" of learning. The practice of the tutorial system plan is: Paper test. One teacher writes first, all teachers participate, express their opinions, and after full deliberation and discussion, an understanding is reached. The reference of the paper comes from the original coordinates. The final version is finalized by the main lesson preparers. Then the teachers of each class supplement the cases according to the actual situation of the class and implement them in classroom teaching. The tutoring plan is distributed to students before class, and students have a general understanding of learning objectives and learning contents, which provides guidance for teachers to implement target teaching in student-centered autonomous classrooms and practical tools for implementing group teaching. It also prepares question materials for students' autonomous learning and cooperative learning in autonomous classroom. Exercises should be carefully designed according to the students' situation. Only by using exercises flexibly and correctly can we improve teaching efficiency and get twice the result with half the effort In practice, we should optimize teaching methods. Teachers should first create a democratic, relaxed and harmonious teaching atmosphere. Teachers should treat students with sincere eyes, educate students with cordial tone and guide students with trusting attitude. Only in an equal and relaxed atmosphere can students study happily and get good grades. Secondly, teachers should have a sunny attitude. Every day, they come into the classroom with a smile. They have a sense of humor in class and students like you. Your classroom teaching is half successful. Only by giving the class to students, paying attention to their activities, their lives, cultivating their desire for expression and sense of competition, and bringing passion to students with classroom body language, students will feel that class is a kind of enjoyment. 3. Creating an effective classroom evaluation system, promoting students' all-round development and teachers' continuous progress, strengthening teachers' self-reflection and improving classroom teaching behavior is another breakthrough point to create an efficient classroom. Teachers should first give full confidence and affirmation to students who dare to ask questions and express different opinions, so as to cultivate students' scientific attitude of daring to explore and question. Teachers should be open-minded when dealing with objections. We should be good at digging up bright spots, grasping the opportunity of instant evaluation, and using accurate and standardized language and appropriate action expressions to conduct classroom evaluation. While paying attention to students' evaluation, teachers should also actively reflect on their teaching behavior after class and constantly improve their teaching behavior. It is necessary to create an atmosphere of cooperative research, and at the same time give the evaluation criteria to students to listen to their feelings and opinions on subject teaching. Not only can we understand students' mastery of knowledge, but developing students' intelligence can solve students' problems in time, thus achieving the effect of mastery and improvement. In short, it is necessary to change the concept, change the classroom into a learning room, and change the teaching time into hours; It is necessary to establish a sense of responsibility, cherish time as gold in class, influence students' time concept with their own time concept, organize the use of information technology to assist teaching and improve teaching efficiency; Give students the initiative in class and realize the maximum benefit of classroom teaching in an all-round and efficient way.
