How to create an effective math class 1 Creating an effective classroom is inseparable from effective lesson preparation.
The formulation of teaching objectives should be combined with reality. For the preparation of mathematical knowledge and skills, according to the breadth and depth of the teaching materials and the students' foundation, we should determine the key points and difficulties, find out the ways to break through the difficulties, and prepare the connection point of old and new knowledge. Mathematics teachers should focus on how to organize and design effective mathematics activities and realize the interaction between teachers and students. When preparing lessons, we should design suitable topics according to the students' actual situation, arrange them in all aspects of teaching according to the training level, combine teaching with practice, and take training as the main line to improve learning efficiency. When learning the definition of ellipse, in the process of preparing lessons, the following three links are designed: (1) Review the definition of circle first. A figure composed of all points whose distance from a plane to a fixed point is equal to a fixed length is called a circle, a fixed length point is called a center, and a fixed length point is called a radius. This is what students learned in junior high school, and then they put forward a new question: What figure will be formed when the sum of the distances of two fixed points on the plane equals to a fixed length? Old and new knowledge will naturally be linked. (2) Students begin to draw ellipses. Students draw ellipses with ropes in pairs. (3) Using the multimedia geometric sketchpad to demonstrate the formation of the ellipse, and further obtaining the conditions for forming the ellipse through observation. Through the above three links, students can easily get the definition of ellipse.
Second, whether preparing lessons or teaching, emotional input should be carried out.
Teachers often say that if students want to like the class you teach, they must first like the teacher, which is actually emotional input. It is very important to establish a good teacher-student relationship between teachers and students in a good math class. When preparing lessons, we should always think about students, how to arouse their enthusiasm and make them the masters of the classroom, so as to prepare lessons well and attend classes well. Chat with students after class to learn about their knowledge level, confused mental state, acceptance, hobbies, personality differences, etc. Teachers should first gain the trust of students, form an emotional chain, and keep close contact with teachers and students in class, so that students can have a relaxed and happy learning environment and lay a solid foundation for improving learning efficiency. In addition to the above points, teachers can also give full play to the role of exercise books, not only to correct mistakes, but also to play an important role: they can communicate the feelings between teachers and students. After correcting the homework, you can use the break time to communicate with individual students to help analyze the wrong questions, or you can talk to students to keep abreast of their learning situation. Besides, can I play my homework? Message function? Students have made progress, write some encouraging words and give good advice to remind them to pay attention when they know their mistakes and don't change; After New Year's Day, write Happy New Year's Day. Students will feel very warm when they see it.
Third, finding ways to stimulate students' desire and interest in learning can improve classroom efficiency.
As the saying goes, interest is the best teacher. In teaching, we should try our best to mobilize students, make them have a strong interest in learning and fully mobilize their enthusiasm. In the application of the theorem on sine and cosine, combined with some practical examples, some questions that students are interested in are put forward, such as how to measure the height of school flagpoles. Students have learned the basic answers in junior high school, and further put forward how to measure the height of the flagpole blocked at the bottom. Students discuss and actively participate in teaching activities, which also enlivens the classroom atmosphere. Under the guidance of teachers, completing teaching tasks in students' discussions and answers can help students feel that mathematics comes from life and solve many practical problems. It is very important for students to be interested in learning mathematics and build up their self-confidence.
Fourth, give students the opportunity to show in class and build their confidence.
In the process of teaching, teachers will ask many questions, but sometimes they are afraid that students will delay answering and cannot complete the teaching task, so they become self-questioning and self-answering. The teacher gave the answer before the students thought it over carefully. It is meaningless for students to listen. Over time, students are too lazy to think and answer questions in class, which has completely become a one-man show for teachers. When learning to choose 4 chapters of geometric proof, the teacher can give the selected examples first, then let the students think about the proof method, and then let the students answer and supplement after thinking. If the students are not active enough and no one answers, will this test the teacher? Skills? Yes Teachers should find ways to mobilize students? Live broadcast? Get up and let the students be the masters of the class. More time will be left for students in class, so that students can think positively and solve problems by themselves, and students will be interested in learning. Carefully select some exercises after class, and students will finish them after class. Students can think, discuss and prove a geometry problem with strong interest, and feel the joy of success, which can greatly improve their self-confidence.
We should have a sense of unity and cooperation, learn more, communicate more and learn from each other.
There are often some problems in teaching, so we need to communicate with colleagues and classmates and learn from each other. Don't build a car behind closed doors. Only by grasping the important and difficult problems in place and thoroughly understanding the difficult problems can we be handy and comfortable in class. Young teachers, in particular, should take the initiative to learn and communicate, get familiar with textbooks as soon as possible, master the knowledge system, pay attention to difficulties and communicate with students more, so as to make great progress in teaching.
Creating an effective classroom is inseparable from teachers' research. Teachers should have the concept of lifelong learning and constantly learn to recharge themselves, so as to make progress, make efficient use of the classroom, and let students gain more and make greater progress.
