I. Changing Teaching Concept and Teaching Mode In China's long-standing traditional teaching model and concept, teachers have always been the main body in classroom teaching, mainly relying on teachers to directly instill textbook content into students on the podium, while students can only passively accept knowledge or directly adopt rote learning methods to complete learning tasks. In fact, this is a very serious misunderstanding, and such teaching will greatly dampen students' enthusiasm and enthusiasm for learning. In the concept of new curriculum standards, students' dominant position in teaching is emphasized, and the development and conduct of mathematics teaching must always be student-centered. For example, when we learn a new formula or concept, our math teacher must not give the final conclusion and result directly, but take the way of guidance and help to make students fully understand the problem and give a reasonable reasoning process, and pay attention to students' independent thinking and problem-solving ability.
Second, the involvement of multimedia teaching methods With the rapid development of scientific information technology, its application in our social life is also increasing. Therefore, we can also make full use of multimedia technology resources and apply them to senior high school mathematics teaching. As we all know, multimedia has many advantages, such as rich content, advanced information and novel methods. These characteristics just meet the requirements of the new curriculum standard for teaching innovation, so it is in line with the requirements of the times to realize the intervention of multimedia teaching methods in senior high school mathematics teaching. For example, when we explain the Pythagorean theorem, if the teacher simply explains the contents in the textbook, it will often make some students with poor abstract thinking ability have insufficient understanding of this knowledge point, so it is difficult to clearly grasp its various applications and the learning effect is not good. If we can use multimedia teaching methods to add graphics, animation and sound media to the explanation of related knowledge, it will undoubtedly make the teaching content more vivid and concrete, and make it easier for students to master and understand the classroom content.
Third, improve the quality of teachers.
Teachers' professional knowledge level and their own quality will greatly affect the quality of this course. Under the concept of new curriculum standards, higher requirements are put forward for our senior high school math teachers. If we want our senior high school math teachers to improve their own quality, we must do the following three things well: (1) Prepare lessons carefully before class. A good beginning is half the battle, so the teacher must fully analyze and think about the content of the next day, especially the difficult problems. (2) Key explanations in class. The content of each class is very rich, but as a teacher, we must learn to be concise. Not every question takes a lot of time to explain. Be sure to make a choice and analyze the key knowledge in detail so that most students can master and digest it. (3) Seriously summarize after class. "Review the past and learn new things, and you can be a teacher." A good math teacher must sum up what he explains in class every day, have enough understanding of the problems in class, analyze the reasons and find out the reasons.
