Teaching reflection: This is the second lesson about plane rectangular coordinate system. The idea of combining numbers and shapes has just arisen among students, and the plane rectangular coordinate system is not very familiar with it. The content of the textbook is simple, but it is necessary to tap the educational resources and give the course more vitality. In the three problem situations of this lesson, we not only reviewed and consolidated the knowledge of the number axis, but also narrowed the distance between life and teaching classroom, laying the foundation for the study of this lesson.

Throughout the whole class, taking student activities as the main line and returning the class to students from beginning to end, there are many ways of cooperation in teaching-double cooperation, group cooperation and class cooperation. The enthusiasm of all the students was fully mobilized, and the class was active. With the joint efforts of the students, the teaching task was completed.

Advantages of distance teaching itself: it adds color to the dull study life, and it changes the relationship between teachers and students in traditional teaching, making it easier for them to establish the relationship of * * * learning or mutual learning. At the same time, distance teaching also provides a broad space and various possibilities for students to cooperate, making personalized learning a reality.

In the classroom activities, I make full use of distance education resources-CD-ROM, from the creation of situations to the giving of questions, to the regional division of plane rectangular coordinate system, from which I not only learned the application of modern information technology, but also obtained a good method to stimulate students' interest in learning. I know that the curriculum resources of mathematics are very rich, and the rich curriculum resources have yet to be explored. Students are the main body of learning, so we should try our best to arouse their enthusiasm.

Although I work hard to prepare lessons and organize classes, there are still many shortcomings in the teaching process: for example, there are many knowledge and details, which make a small number of slow-accepting students fail to get a good understanding and exercise, and let me understand the orderly and gradual expansion of knowledge; Sometimes the classroom atmosphere is not active enough; Students' classroom expression ability needs to be strengthened. In the process of teaching, it may be too high for most students to ask students to understand the thinking method of mathematics, understand the value of mathematics and sublimate their emotions in just a few minutes in class. The effective way is to combine in and out of class, and assign relevant learning tasks to students before class, so that students have enough time to think.

I believe that when I take this course again in the future, I will improve the shortcomings of this course, strive to improve my teaching level, and make students willing to learn and enjoy learning.
