According to the teaching requirements of the new curriculum reform, high school mathematics should focus on high school students, make full use of the surrounding environment and materials, actively cultivate the ability of high school students to observe, experiment and summarize mathematical laws, improve students' thinking ability to guess, analyze and summarize mathematical knowledge, and improve students' practical operation ability to calculate, prove and summarize mathematical propositions and theorems. As the main position of high school mathematics education, high school mathematics classroom is the main battlefield to realize this lofty teaching goal. Therefore, high school mathematics classroom education is the focus of high school mathematics teaching. In order to achieve good results, students must be able to impart necessary knowledge points and carry out appropriate exercises training within limited classroom time, so as to achieve the corresponding mathematics classroom teaching effect. Traditional high school mathematics generally only "instills" basic mathematics knowledge points in the classroom. There is no time left for students to practice exercises and discuss problems, which leads to inefficient classroom teaching. It is not only the inevitable trend of high school mathematics teaching to create an efficient high school mathematics teaching classroom, but also reflects the practical significance of high school mathematics teaching. On the one hand, efficient classroom teaching can improve high school students' interest in learning and enhance their mastery of knowledge. On the other hand, efficient classroom teaching can promote the change of teachers' teaching concepts and methods and improve classroom teaching efficiency. Therefore, it is of great significance to build an efficient high school mathematics classroom.
Second, the creation of high school mathematics efficient teaching classroom specific measures
1. Improve teaching methods and teaching means.
In order to build an efficient high school mathematics teaching classroom, we must break through the shackles and shackles inherent in the traditional teaching model, change our backward teaching concepts, adopt advanced teaching concepts, and constantly improve teaching methods and teaching means. The specific steps to improve and perfect the teaching methods and means of senior high school mathematics are as follows:
First of all, we should pay attention to introducing advanced teaching ideas, innovating teaching ideas, changing the dullness and tedium of old-style teaching, establishing scientific and reasonable teaching methods, and constantly improving the interest of high school students in learning mathematics, thus improving the teaching efficiency of high school mathematics classroom. Secondly, in the process of improving and perfecting classroom teaching methods and teaching means, we can't stick to the rules and stay the same, but we can't just meet the learning needs of high school students. It can also adapt to the development of the times. For example, the "experiment" teaching method can be used in actual teaching activities. "Experiment" teaching method has the function of making problems abstract, concrete, boring and vivid, and can cultivate high school students' practical operation ability, mathematical law observation ability and mathematical knowledge understanding ability. The following article takes trigonometric function in senior high school mathematics as an example to elaborate in detail.
In the image teaching activity of trigonometric function y=Asin(ωx+φ), three experiments can be set up first: first, draw the images of y=sin(x+) and y=sinx in the same coordinate system to get the influence of φ on the images; Secondly, draw the images of y=sin(2x+) and y=sin(x+) in the same coordinate system, and get the influence of ω on the images; Thirdly, draw the images of y=3sin(2x+) and y=sin(2x+) in the same coordinate system, and get the influence of A on the images. In this way, the experimental topics are gradually put forward, studied, summarized, demonstrated, applied and extended, and good classroom teaching results have been achieved.
2. Student-centered, constantly stimulate interest.
High school mathematics is theoretical and abstract, and students have great difficulty in learning and low interest. Therefore, only by giving full play to their learning initiative and cultivating their interest in learning can we effectively improve the classroom teaching effect of senior high school mathematics. The specific implementation steps are as follows: first, teachers should closely follow the learning characteristics of students at all stages to carry out diversified classroom teaching; Secondly, we should adopt a variety of advanced teaching methods (such as multimedia) to carry out classroom teaching. Thirdly, we should carefully design interesting teaching leads, and finally, we should strive to create a harmonious classroom teaching atmosphere. As long as we do the above four points, we can stimulate high school students' interest in learning and improve the effect of classroom teaching. Here we will take the knowledge point of "straight line point-oblique equation" in high school mathematics as an example to elaborate in detail.
In the teaching process of "the point inclination equation of a straight line", we can set several questions: the straight line L passes through P0 (x0, y0) with a slope of k, P(x, y)∈L, so as to find the relationship between X and Y; Whether the coordinates of points on a straight line can satisfy the equation; What is the relationship between oblique type and point oblique type, and so on. Therefore, creating "situations" and "questions" through questions to stimulate students' interest in learning can not only enhance students' learning consciousness, stimulate their thinking and cultivate their consciousness, but also improve the teaching effect of senior high school mathematics classroom.
Third, the conclusion
In a word, in high school mathematics teaching activities, teachers should give full play to students' main role, enhance students' interest in learning, constantly improve and perfect teaching methods and means, and strive to create an efficient high school mathematics teaching classroom, so as to effectively improve the teaching effect of high school classroom.
