Through this online training and study, I listened to the new educational ideas of experts and scholars, learned the teaching ideas of many excellent teachers, gained a lot, and realized my own shortcomings in teaching. This training is timely and profound, and its impact will be far-reaching. Further understand and master the development direction and goal of the new curriculum reform, and reflect on my own shortcomings in my previous work. As a teacher, I know that I still have many immature places in mathematics teaching and many shortcomings in teaching, but through these days' study, I firmly believe that I will make greater progress in my future work and study.

First, the promotion of mathematical concepts.

? Although we have been engaged in education for some time, in the face of today's situation, the times require us to keep forging ahead, absorb nutrition and contribute to the rapid development of education in the motherland. In this study, the teacher summed up the thinking method and activity experience of mathematics for us, which made me have a deeper understanding of mathematical concepts. The application of many mathematics teaching ideas and methods in mathematics teaching is complex and effective, such as set thinking, corresponding thinking, symbolic thinking, reduction thinking, analogy thinking, classification thinking, statistical thinking, extreme thinking, modeling thinking and so on. I just lack such a theoretical basis, which makes me lack height and depth in actual teaching. The teacher's discussion on the relationship between classroom teaching presupposition and generation is very close to our actual teaching, which is also the most troublesome link we face in daily teaching, especially in open teaching. In addition to teachers' own improvisation ability, they should also absorb rich ideas, so as to truly have the ability to control the classroom.

Second, the change of teaching behavior.

? In this training, I also have a further understanding of the tasks that every teacher has to face in preparing lessons and attending classes. The expert teacher's explanation provides some reference methods for our thinking in these aspects. We should integrate theory with practice, and make good work goals for ourselves at the beginning of the semester according to our daily workload. In short, it is to carry out teaching research selectively to ensure that the limited teaching time is fully utilized. It can be said that the number is small, but the essence is important. I think this change in teaching behavior can be really applied to our actual work, and students can get more effective teaching.

Third, pay attention to learning teaching reference.

I think only by studying the teaching reference carefully and reading every chapter, every knowledge point and every question in the textbook carefully. Only by carefully calculating, understanding and seeing through the teaching materials can we fully grasp the important and difficult points of teaching and accurately impart knowledge to students.

? After this training, I realized that every teacher should actively participate in the curriculum reform, not be a bystander, but be an active implementer of the curriculum reform. After studying, I also deeply understand the importance of learning. Only by studying constantly can I improve continuously. I think that only through the joint efforts of all teachers, changing the way of learning and promoting "deep learning" can students grow up happily and the Chinese nation stand forever in the world. I am willing to contribute my life to the education of the Chinese nation.
