Some educational structures are also taking full advantage of the advantages of e-learning to attract more people. Literature [4] mainly describes how to identify and analyze factors that contribute to the design of e-learning applications. Literature [5] mainly discusses the application of modern educational technology in computer teaching. On university campuses, using the convenience of 5G and the Internet, they have gradually formed a model of curriculum education resource sharing, which can share teaching resources, as well as the sharing of teacher resources, curriculum resources, and advanced teaching facilities. Literature [6] is based on the DBR educational research paradigm and verifies the original concept through practical exploration in real situations. Literature [7] conducted a series of data analyses and research on the application of data mining technology in student performance. Analyzed the internal relations and teaching rules between the various courses. With the advent of the Internet age, the use of big data analysis technology has become a method and technology used in many fields, and big data has also promoted the reform and innovation of various universities. With the development of science and technology and the prevalence of Internet technology, compared with traditional networks, 5G networks have the advantages of low coverage, low energy consumption, and high capacity in hot spots. It can carry out data dissemination very well. According to the current state of extreme scarcity of educational resources, some places do not have advanced teaching resources, and it is necessary to use the convenience of the Internet to communicate and share on the Internet. Literature [8] starts from the design concept of the smart campus and studies the application of data mining technology in the smart campus system under the background of big data. Literature [9] analyzes the characteristics and advantages of the university listening and speaking teaching mode under the network environment.

2. Basic Theory
2.1. The Application of 5G Smart Technology in Education
5G is the foundation of the intelligent Internet. In the teaching process, it is equipped with information technology such as remote interaction and artificial intelligence, which is deeply integrated with course teaching, enriches classroom teaching, allows students to participate in teaching, and enhances students’ interest in learning. Teachers can teach students in accordance with their aptitude through real-time interaction with students. Many excellent teaching resources can be shared on the Internet; through the Internet, students can study outside of class, check deficiencies, and realize the universalization of education. Even in the most remote rural areas, as long as they have the Internet, they can enjoy rich and high-quality education. Resources, to achieve the sharing of educational resources. In the field of education, 5G + Al will give birth to intelligent education, embodying a people-oriented teaching model. Through the close integration of Al and big data technology, under the support of 5G network, the teaching data related to the teaching behavior of the teacher in the classroom and the student's listening effect are captured in real-time through the intelligent teaching terminal, and the method and method of the teacher's teaching in the teaching are extracted by using big data analysis technology. Based on the unstructured behavior data generated by the students' listening state, the extracted unstructured data is effectively analyzed and summarized with the help of AI algorithms, cloud computing, etc., and finally using data visualization technology, according to the data results generated by teachers and students, teaching managers, teachers, and students provide scientific behavior analysis reports, which are displayed to relevant teaching management institutions and class teachers to assist teaching management and improve teaching quality. For parents, they can observe students' learning conditions online, realize online tutoring, and protect their children's healthy growth. The application of 5G in the education industry is shown in Figure 1:
5G and intelligent technology have brought a lot of convenience to the work and study of teachers and students. Intelligence means that the campus has a scientific research cloud, intelligent classroom, campus security, and other platforms. Teachers can read papers online and evaluate oral English. Students can also learn online, and parents can tutor online; the platform will introduce student information and teaching resources into the platform. The intelligent technology + education will further extend the information interconnection from the breadth to the colleges and universities, from the depth to the organization of colleges and universities, and smooth informatization.
2.2. Construction of Intelligent Education Model
The development model of the smart education resource innovation ecosystem is the progression and deepening of the “Internet +” education development model and is the product of smart technology + education resources. Internet education takes communication and social interaction as the core content, realizes the connection between learners, and establishes a learning website, connects learners and campus services, that is, establishes external connections between learners and campus, and makes the campus service information communicated to learners more efficiently and quickly. The intelligent technology + education will further extend the information interconnection from the breadth to the various colleges and universities, from the depth to the internal organization of the colleges, and smooth informatization, so that the school can reorganize the learning elements and the needs of the learners. The management operation mode, so as to achieve efficient coordination between learners and school management operations, and more efficient matching of information supply and demand. The intelligent education model diagram is shown in Figure 2:
The development mode of the intelligent education resources innovation ecosystem is progressive and deepening of the “Internet +” education development mode and is the product of intelligent technology + education resources. Internet education takes communication and social interaction as the core content, realizes the connection between learners, and establishes a learning website to connect learners and campus services, that is to establish the external connection between learners and campus so that the service information of campus can be more efficiently and quickly conveyed to learners. The new ecosystem of intelligent education provides services for learners. Learners feedback data to the new ecosystem of intelligent education, and the information fed back can generate educational resources through the new ecosystem.
2.3. Analysis of Intelligent Teaching Mode
Based on the 5G mobile network, it is possible to achieve lectures by famous teachers in the near-end classrooms, interaction, auditing, and commenting in the remote classrooms, and to achieve smooth listening and free evaluation in campus scenarios such as remote recording and broadcasting classrooms, dual-teacher classrooms, and smart classroom delivery. Classes, centralized control, 5G remote listening, and evaluation classes have greatly improved in response speed, image quality, feedback timeliness, and evaluation effectiveness. Realize online patrol realize the diversification of teaching evaluation. Supported by the 5G network environment, teaching evaluation collects a full range of data through the observation of learners' online or offline learning process, discovers their participation in learning behavior patterns, excavates their thinking process to complete tasks, discovers problems in real-time, and solves the process. In order to realize the real-time and accurate evaluation of the problems encountered in the process and the formulation of intervention methods, the realization of multimodal learning data collection, full-scene demand analysis, and three-dimensional evaluation, and realization of guidance and improvement based on the results of learning evaluation. The intelligent education model diagram is shown in Figure 3:
2.3.1. Personalized Learning Mode
Teaching should pay attention to teaching students in accordance with their aptitude because each student's learning methods and mastery of knowledge are different. Personalized education is based on the current learning status of each student to implement education in a targeted manner. With more and more student and learning data recorded by the system, it is more difficult to achieve targeted and personalized education. Intelligent teaching solves this problem very well. The system will conduct a test on the students’ learning situation and difficult points, and the test results will be transmitted to the teacher’s computer. The teacher can customize the learning plan according to each person’s situation. Students can also master their learning situation, so as to carry out targeted exercises, and truly teach students in accordance with their aptitude.
2.3.2. Diversified Learning Modes
The traditional teaching method is basically in a fixed place, teaching according to fixed textbooks, and teachers will teach fixed content according to the requirements of the school. This traditional teaching mode will be restricted by time, place, and space. With the development of science and technology, the new educational model can break the shackles of this traditional teaching concept. Teaching is not limited by time and place and realizes “learning all the time.” Students can choose to learn effectively according to their own learning progress and learning intensity. Learning should be people-oriented and focus on content rather than form, so as to keep pace with the times.
Differentiated learning is an individualized teaching method, in which teachers adjust the teaching process and products according to students’ learning willingness, interest, and learning style. Its learning plan focuses on content, while the learning content of all students remains the same. It is a school- and curriculum-centered approach that attempts to modify the way that is content is taught to meet student needs, differing strengths, and general readiness. Personalized learning looks at the learner, thinking about the question, “What does this student need to know, and how best to do that?” It is a student-centered approach to learning that is built around recognizing the vast differences between students, not only in literacy or diagramming abilities but also in the real needs of students.

4. Simulation Experiment
4.1. Analysis of Student Performance
4.1.1. Traditional Teaching Mode
The score analysis data are shown in Table 1 and Figure 4:
4.1.2. Network Multimedia Teaching Mode
The score analysis data are shown in Table 2 and Figure 5:
From Tables 1 and 2, we can see that the monthly test scores of the experimental class, the control class, and the standard class under the standard teaching mode are 68.67, 67.69, and 65.78, respectively, and the scores under the network multimedia teaching mode are 73.50, 72.27, and 70.24, respectively. The results of the online teaching model are generally higher than those of the traditional teaching model. Among them, the performance of the experimental class has a higher degree of increase, with an average increase of 4.83, indicating that there are significant differences in the learning and cognitive abilities of students under different teaching models.
4.2. Analysis of Students' Knowledge Mastery
In order to test the students’ mastery of knowledge under the two different teaching modes, we issued questionnaires to the students in the experimental class, the control class, and the standard class under the two different teaching modes, and compared the results obtained. The experimental conditions are shown in Figures 6 and 7.
From Figures 3 and4, we can see that under the traditional teaching mode, students have a low degree of knowledge mastery, with a complete mastery rate of only 15%. Under the network multimedia teaching mode, the student’s knowledge mastery rate has been greatly improved. The complete mastery rate is as high as 45%, and the students’ mastery of knowledge has been excellently improved, indicating that the network multimedia teaching mode can stimulate students' interest more in learning and improve learning efficiency.
4.3. Comparative Study of Teaching Design
Under the traditional teaching method, teachers generally use the textbooks issued by the school to teach. The traditional teaching methods will inevitably have some shortcomings. In the online teaching mode, the teacher will make the key content of the classroom into a PPT and display it in the classroom, which is not only convenient for the students, we understand the key points of the classroom, and it is also convenient for students to save and review later. In order to study the differences in the sources of teachers' lesson preparation resources, we have investigated the sources of lesson preparation resources of three different types of teachers, as shown in Table 3:
From the survey results in Table 3 and Figure 8, we can conclude that the three different types of teachers have the largest proportion of downloading course resources through the Internet; we have conducted research and investigation on whether to use courseware in class and the performance of students in class. The survey results are shown in Tables 4 and 5.
From the research results in Figures 9 and 10, we can conclude that when multimedia teaching is not used, students’ cooperation rate, classroom practice accuracy rate, and classroom completion rate are low. However, these problems have been improved after multimedia teaching is used. The cooperation rate of students and the accuracy of classroom exercises have been greatly improved. The accuracy rate of the experimental class is as high as 62.4%, and the thinking ability of students has also been greatly improved.
5. Conclusion
Artificial intelligence empowers education reform, and the superiority of technology is vividly reflected. However, although all countries have achieved good results, the shortcomings of artificial intelligence empowerment are gradually exposed. In order to guide the development of artificial intelligence-enabled education, it is necessary to analyze the international experience and current problems and propose new directions for future artificial intelligence-enabled education. Make education fairness a reality and achieve the highest quality educational resources in the shortest time.
