German educator Steward said: The essence of teaching art lies not in the essence of teaching, but in inspiration, awakening and encouragement. This means that teachers' teaching content and teaching methods should stimulate students' emotions, stimulate their interest in learning, make them accept teaching in a pleasant emotional experience, and make teaching activities an interesting activity that both teachers and students are willing to participate in. Some people think that special materials are needed to stimulate students' interest in learning. I think this is a misunderstanding. In fact, problems in books, even ordinary and familiar problems, can stimulate students' interest in learning as long as teachers guide them properly.
Good teacher-student relationship is the guarantee to improve the efficiency of senior high school mathematics classroom. Schools and teachers are the most important environment for students. The relationship between teachers and students directly affects or even restricts students' emotions and will, and affects students' learning motivation and learning effect. In the ancient Chinese educational masterpiece "Xue Ji", it was mentioned that "we should be close to teachers and believe in our own methods". And believe that it can be good, even good. "This shows that only by establishing a harmonious relationship between teachers and students and letting students get close to teachers can teachers win the trust of students and enjoy high prestige. Students will like him and then accept his education. Modern educational theory holds that harmonious, harmonious and equal teacher-student relationship plays a special role in the teaching process. It shortens the distance between teachers and students, and makes students' learning motivation rise from the simple cognitive need for knowledge to the emotional need for future development. On the contrary, the disharmony between teachers and students will cause students to have resistance in the teaching process; Thereby reducing students' cognitive acceptance of knowledge and leading to a series of problems such as low academic performance.
Therefore, if teachers and students are in a state of trust, understanding and cooperation in the teaching process of senior high school, the harmonious, pleasant and interactive educational atmosphere it creates will inevitably produce good teaching results.
Third, understand the students' preview status and determine the students' "nearest development area"
The "zone of proximal development" of students is the most direct and influential knowledge and skill foundation and emotional state for students to accept new knowledge, develop new skills and open up new ideas. In teaching, it is of great significance to understand students' preview status and find out their "recent development area" for improving classroom efficiency. Students' "zone of proximal development" is the starting point of our teaching. On the one hand, teachers can avoid treating students as a blank sheet of paper, making teaching lower than students' existing thinking level, unable to stimulate students' interest and motivation in learning, being concise, avoiding unnecessary repetition and improving the efficiency of mathematics classroom. On the other hand, teachers can also start from the "nearest development area" of students. Therefore, teachers should know about students' preview and find out their "recent development areas", so that teachers can not only have clear goals, but also make students feel natural and friendly, and give them room for further improvement and thinking.
Fourth, pay attention to the general method and turn multiple solutions to a problem into multiple solutions.
The author found that many teachers are concerned about multiple solutions to one problem. This is necessary, because multiple solutions to a problem enable students to think from multiple angles, which is conducive to inspiring students' thinking, broadening their horizons and enhancing their ability to analyze problems. However, the author believes that as an excellent math teacher, it is far from enough to pay attention to multiple solutions to a problem, but also to multiple solutions, that is, the general method. Paying attention to general methods can help students solve the problem of "sea tactics" fundamentally, and play a role in fueling the fire, so that teachers can bring the greatest gains to students in a short class. In mathematics, the general method in a broad sense can be understood by Paulia as "how to solve problems", but it is abstract and difficult for students to understand. The narrow general method can be understood as a method that can solve a class of mathematical problems with the same characteristics. Teachers must observe and summarize more, and guide students to discover laws.
Therefore, teachers can pay attention to the general methods and turn multiple solutions to a problem into multiple solutions, which can save time, increase classroom capacity and improve classroom efficiency.
Fifth, make full use of modern teaching methods to improve classroom efficiency.
The application of modern technology is the focus of teaching reform. Multimedia courseware-assisted teaching is one of the important means of classroom teaching. It vividly presents information and knowledge to students in a random, flexible, all-round and three-dimensional way. Use multimedia technology and situational pictures to stimulate students' curiosity and thirst for knowledge in all directions and from multiple angles. In addition, the application of modern teaching methods can increase capacity, save time and improve classroom efficiency.
Students' mastery of knowledge generally begins with perception. With rich perception, we can lay a good foundation for further forming concepts, understanding and mastering laws. Some contents in the textbook are not easy for students to accept only by the teacher's oral explanation. If multimedia technology is integrated into graphics according to the characteristics of movement, freeze-frame, flicker and color change, combined with our knowledge, we can break through the difficulties of knowledge and develop students' mathematical ability. For example, the abstract thinking ability of middle school students is in the development stage, and the definition of functional parity is very abstract, which is a difficult point for students to learn. It is difficult to solve the problem completely only by the teacher's oral explanation. Therefore, our teacher can make such a courseware, and the main steps are as follows: (1) Show a series of function images, some of which are symmetrical about the Y axis, some are symmetrical about the origin, and some are asymmetrical, so that students can choose after observation. (2) Erase the left parts of the three functional images selected on the Y axis respectively. (3) Restore the erased part. If symmetry is found, the image can be restored by symmetrical points, but it is difficult to restore the image without symmetry. (4) Summarize the relationship and characteristics of the definition domain satisfied by the resolution function corresponding to symmetric images. (5) The concept of function parity is formed and further discussed. Through this courseware, students are provided with enough perceptual materials to help them achieve a leap in understanding as soon as possible. It can be seen that combining the difficulties in teaching and skillfully using multimedia teaching can successfully break through the key difficulties and complete the teaching objectives.
The application of multimedia in mathematics teaching is a major trend and feature of modern education. Because modern multimedia has the characteristics of diversity, novelty, artistry and interest, it can better help students fully perceive and deeply understand the teaching materials, quickly rise from perceptual knowledge to rational knowledge, and overcome the defects in traditional teaching. At the same time, due to the use of multimedia, math teachers are freed from the tedious blackboard writing and repeated introduction of basic knowledge, and have more time and space to cooperate with students and learn interactively, which increases the classroom capacity and greatly optimizes the teaching process. In addition, due to the use of multimedia, students' understanding can be changed from intuitive to abstract, and students' intellectual and non-intellectual factors can be fully mobilized to participate in cognitive activities, thus enhancing their motivation and ability to understand. In addition, multimedia can provide alternative experiences and make students easy to learn, understand and remember. Therefore, it can shorten the time to understand and master the knowledge, accelerate the cognitive process, and make them learn more, faster and better at the same time.
In short, teachers should fully study the situation of students and teaching materials, make full use of all available resources around them, and improve classroom efficiency.
