With the development of educational technology, information technology with multimedia technology and network technology as the core has penetrated into our work. How to promote the universal application of information technology in the teaching process and promote the integration of information technology and subject courses is an urgent problem for every educator. Therefore, the author analyzes the advantages and existing problems of applying educational technology in the teaching process, and puts forward some views. With the advent of the era of knowledge economy and the rapid development of modern science and technology, great changes have taken place in all fields and industries of society, and education is no exception. Modern educational technology also shows its unique charm in the reform of education and teaching. More and more new teaching media and means are applied to education, and the application of these technical means is bringing about changes in educational concepts, methods and management. Modern educational technology can effectively promote students' active participation in the learning process, so that students can arrange their own learning according to their actual abilities and learning needs. Providing teachers with more diverse and advanced teaching methods, teaching models and teaching concepts is an effective way to improve teaching. Therefore, how to make full use of modern educational technology with information technology as the core in professional teaching has become a hot topic in educational reform in various countries. Through the design, development, utilization, evaluation and management of teaching process and teaching resources, the theory and practice of teaching optimization are realized. Second, in the traditional teaching process, make use of the advantages of modern educational technology (1) to create situations and stimulate interest. Interest in learning is the most important motivation for students to acquire knowledge, broaden their horizons and enrich their psychological activities. Integrating multimedia technology into mathematics classroom, using its characteristics of illustrated pictures, synchronized audio and video, and dynamic and intuitive images, we can create various situations for students, which can mobilize the participation of students' various senses, stimulate students' strong desire for learning, stimulate their learning motivation and interest, and thus achieve the purpose of improving students' enthusiasm. (2) Change the static state into the dynamic state, and break through the key and difficult points of teaching. In the teaching process, some teaching contents are abstract. It is difficult to achieve ideal results through traditional teaching methods. At this time, multimedia can make up for these defects, help teachers reveal laws, expand content and develop students' thinking more easily. At the same time, it can also save a lot of time and improve learning efficiency. Problems arising from the application of modern educational technology in traditional teaching Faced with the application of educational technology in recent years, most teachers can clearly realize that advanced educational technology, especially information technology, has brought symbolic changes to the reform and development of education. But at the same time, we should also see that there are still some shortcomings in the application of educational technology in the classroom. Some teachers still have many misunderstandings when using it, and they have not really played the role of advanced educational technology. Many problems need to be discussed together, and a lot of work needs continuous improvement. Fourth, the countermeasures to solve the problems existing in educational technology (1) Change ideas, correctly understand modern educational technology means, carry out educational reform, and guide ideas. A good lesson is to guide teaching with correct modern educational concepts. First, we should focus on changing teachers' ideas and let them establish modern educational concepts. Experts can be invited to teach modern educational technology and innovative education. Feasibility study on on-the-job training of educational technology; Let teachers compare the functional differences between traditional teaching media and modern teaching media in combination with reality, and urge teachers to realize that modern educational technology is an important driving force for the current educational development; Let teachers who have mastered modern educational technology talk about their own learning and application experience; Evaluate high-quality courseware and guide teachers to use modern educational technology reasonably. (2) Education administrative departments at all levels and schools should conduct a comprehensive and objective evaluation of teachers' classrooms. To evaluate teachers' classroom teaching, it is not necessary to add the necessary condition of "modern educational technology", but to comprehensively evaluate whether the corresponding classroom links are suitable for the application of modern educational technology. Add the condition of "modern educational technology" to the evaluation. It has played a certain role in promoting the work of modern educational technology, but we should also pay attention to its negative effects. In order to popularize modern educational technology, we can strengthen the role of supervision and inspection in peacetime and give full play to administrative efficiency, such as stipulating the number of semester hours for using modern educational technology, writing the application experience of modern educational technology for everyone, and establishing a mechanism for mutual discussion. So as to popularize modern educational technology. (3) Strengthen the study of modern educational theory and correctly handle the relationship among teachers, students and computers. The progress of science and technology promotes the development of today's economy and society, and also affects the changes of people's thinking and lifestyle. Facing the ever-changing new knowledge and the increasingly demanding students, teachers should give more and more students a drop of water if they want to keep up with the times. We must strengthen teachers' study of modern educational theory and constantly change their concepts. Changing teachers' ideas and thinking patterns is more important than technology itself. Only by truly realizing the reality and urgency of educational modernization and informatization can we mobilize teachers' initiative and enthusiasm and truly implement modern educational technology. Teachers are the main factors that constitute school education and the main force for schools to implement education. The number, quality and structure of teachers determine and restrict the survival and development of a school. In a sense, the level of teachers in a school determines the level of education, and the quality of teachers is the quality of education. Since the Tenth Five-Year Plan, with the development of China's education, the overall construction of teachers in China has made positive progress, and the overall appearance of teachers is undergoing new changes. Teachers' educational level is improving year by year, their structure tends to improve, and their overall quality is gradually improving. On the whole, the status and treatment of teachers are constantly improving, the social evaluation of teachers' profession is gradually optimistic, and the professional attraction is enhanced. However, due to many defects of private schools, private schools cannot attract more outstanding talents and retain outstanding teachers, which leads to certain problems in education and teaching of private schools and even affects their survival. The construction of teaching staff is a big problem that has been puzzling private schools. Therefore, we believe that to develop healthily, the primary task of private schools is to strengthen the construction of teachers and strive to improve the overall level of teachers. The analysis of the factors affecting the construction of teachers in private middle schools in China cannot be separated from the particularity and basic characteristics of private schools in China. Investing in running schools is the basic feature of the development of private education in China since the reform and opening up. It is a helpless and passive choice for school-running people to embark on the road of investing in running schools. It is also an inevitable choice for the development of private education in a specific period. Investing in running a school is a special development model, which is different from the road of private education in the history of China and the western private education model. A correct understanding of this basic feature of private education in China is of great significance to correctly analyze the factors affecting the construction of teachers in private middle schools in China and put forward measures to strengthen the construction of teachers. In China, private education has directly triggered various investment-related demands through the development mode of investing in running schools, which is an expectation of investors for investment behavior. These expectations are based on the interests of investment. Today, the organizers of private education in China pay attention to school property rights, returns and even profits, which is actually an inevitable and chain reaction caused by investment in running schools. There is no return on benefits. Relying solely on the school-run "spiritual realm" is not conducive to the sustainable development of private schools. When running a school becomes an investment behavior, the biggest impact on private education is the instability of development, which will inevitably reduce its attractiveness and give its employees (teachers) a sense of insecurity, thus affecting the stability and long-term construction of teachers. For some private middle school teachers, they hold a temporary concept and a sense of working, and are not enthusiastic about improving their own quality and making suggestions for school construction. Some teachers may even resign because of low wages. For them, it doesn't matter which school they teach, what matters is whether they can maximize their economic benefits. The key to the healthy development of private schools is the teaching staff. How to build a high-quality and stable team of teachers and make private schools develop healthily and rapidly is an important problem to be solved urgently in China's educational theory circle. The soul of private schools is teachers, whose mentality directly controls their educational behavior, which is directly related to the rise and fall of schools. Many private schools have accumulated rich experience in running schools, and began to infiltrate humanistic factors into teacher management, and put forward humanized personnel management principles such as "keeping people in career, keeping people in treatment, keeping people in feelings and keeping people in environment". In addition, when discussing the construction of teachers in private schools, the nature and characteristics of teachers' profession, the personality characteristics, outlook on life and values of teachers' profession are often ignored. Psychologically, personality characteristics include temperament, ability and personality, and personality can best reflect a person's personality. Personality is the result of continuous shaping in the process of adapting to and transforming the environment. Personality is gradually formed and developed in the acquired social life environment. Personality is formed by subjective factors, natural factors, environment and educational factors. The working environment of middle school teachers makes the people they contact in the working environment mainly minors, while dealing with simple and simple minors for a long time makes some teachers' behavior "degenerate" and even behave like children, so they are insensitive, indifferent and have poor adaptability to social changes. There are few opportunities to contact the society, which is relatively closed, with narrow contact range, less information and less communication. Modern educational technology is a unique field combining theory with practice. With the wide application of modern educational technology in educational practice, the great role of educational technology in promoting the reform and development of education and teaching will become increasingly apparent.
