Wu Huamei of Dongfang Railway Middle School. The development trend of mathematics curriculum under the new curriculum standard 1. The new curriculum, which emphasizes the connection between mathematical knowledge and life, puts forward higher requirements for the application of mathematical knowledge and mathematical modeling in senior high schools. A lot of knowledge starts from practical problems and then goes back to solving practical problems. For example, in the application of functions, it involves practical problems in daily life such as installment purchase, mortgage loan and car purchase; Another example is: in the application of linear programming, when solving the optimal problem, the actual problem is taken as the background. 2. Pay attention to the application of information technology in mathematics teaching. In the process of compiling new textbooks, give full play to the power of information technology and use it to help students understand the essence of mathematics. For example, the arrangement of teaching materials uses information technology to find approximate solutions of equations and so on. 3. Emphasis on students' participation In order to improve students' initiative in learning, new textbooks appear in the form of observation and speculation, reading and thinking, exploration and discovery, which provides students with exploratory and expanding content; In particular, the emergence of exercises and research topics further reflects the importance attached by the new textbooks to students' participation in mathematics teaching. 4. Emphasize the connection between high school mathematics teaching and college mathematics teaching. Many new contents in the new textbook, such as the introduction of definite integral and algorithm, reflect the development direction of the new textbook along the convergence of high school mathematics teaching and advanced mathematics teaching. Second, the high school math class under the new curriculum reform should be like this. According to the development trend of the new curriculum reform, today's high school mathematics teaching should pay attention to the following points: 1 Let mathematics have a process. Traditional mathematics teaching often only requires students to remember conclusions, train problem-solving skills with formulas, and regard mathematics class as problem-solving teaching. Under the new curriculum, high school mathematics teaching emphasizes that teaching should focus on mathematics with background and explain the background and context of mathematical problems. Through the introduction of background knowledge, students can understand the mathematical thinking methods contained in these knowledge and understand the mathematical culture. 2. Make Mathematics Interesting Many students can't learn mathematics well because they think it is boring. The key to improve students' interest in learning is to make mathematics interesting, which requires teachers to carefully explore the interest of teaching materials in the process of preparing lessons. For example, in the teaching of exponential function, the teacher can set such a question: the thickness of a piece of paper is 0. 1㎜, but after being folded in half for 30 times, guess how high it is. Three or four stories high? Or higher? By solving this problem, the answer is much more shocking to students than the magic of the exponential function taught by the teacher. 3. Make mathematics useful. The new textbook has arranged a lot of contents to introduce the history of mathematics development. In the teaching process, teachers should make full use of this content to educate students on the aesthetic value of mathematics and patriotism. In a word, in today's high school math class, apart from emphasizing double-base teaching, it should also show that everyone learns valuable math, everyone gets the necessary math, and different people get different development trends in the new curriculum reform.
