## Abstract

In order to make students more interested in PE learning in PE teaching, it is necessary for PE educators to change the traditional way of thinking, take students as the main body of PE learning, be guided by teachers themselves, and use mobile edge computing and neural network technology as technologies. It enables students to carry out intelligent physical education independently. Whether the teaching is effective does not mean whether the teacher has completed the teaching content seriously, but whether the students have learned something, or whether the students have learned well. Based on the actual teaching practice of flipped sports classroom, this paper takes the “effectiveness” of sports classroom teaching as the breakthrough point, mainly adopts the research methods of comparative analysis, mobile edge computing, and neural network, and combines relevant domestic and foreign research results on the teaching of sports flipped classroom at home and abroad. An in-depth and comprehensive analysis of the effectiveness was carried out. The research results show that it is reliable to build a university sports flipped classroom with a neural network driven by motor skill learning and mobile edge computing as the carrier.

## 1. Introduction

After entering the era of knowledge economy, the competition of talents has become the core of competition all over the world [1]. On the path to strengthening the country through talent, the country should first focus on talent cultivation. In an international competition, anyone with high-quality talents can win [2]. As a result, China views education as a priority for development and makes no effort to implement educational reform. PE teaching should keep up with the times and adapt to the pace of the times as an important part of education [3]. The goal of a flipped classroom is to transform “passive learning” into “active learning,” allowing students to develop an active learning method of “learning before teaching” without even realizing it [4]. The flipped classroom is becoming increasingly popular in the classroom. PE, on the other hand, has a high level of practicality, human adaptability, and other objective laws when compared to other courses. As a result, how to teach in a flipped classroom is a new topic in PE teaching in the modern era [5]. All teachers, including PE instructors, should be relentless in their pursuit of maximization of students’ progress or development. It is critical to investigate the efficacy of PE flipped classroom instruction [6]. People are now aware of the importance of physical education in schools, and there are numerous studies on the subject. However, most of them study from the perspective of changing teaching modes and teaching methods and very few from the perspective of PE flipping classroom teaching effectiveness. I hope this research will make a contribution to the effectiveness of PE teaching.Motor skills are also called “motor skills”. It refers to the ability to master and effectively complete special actions in human movement [7]. One of the basic concepts of PE curriculum standard is to stimulate sports interest and cultivate students’ lifelong PE consciousness. School PE is the basis of lifelong PE, and the habit of sports interest is the premise of promoting students’ learning and lifelong exercise. Motor skill learning is learning based on physical activities and one of the main means to achieve learning objectives in other fields. The field of motor skill learning is the main learning field of PE and health courses [8]. Whether the public PE teaching in schools is effective is related to the physical and mental health of students, the training quality of talents, and the implementation of the national education policy [9]. The effectiveness of PE teaching in schools is of great significance to the formation of their PE concept and the development of PE skills and is related to their physical and mental health to a certain extent. No matter how PE education ideas are updated, how teaching contents are reformed, and how teaching methods are changed, the ultimate goal is to improve the quality of PE teaching and make PE teaching receive good results [10]. That is, PE teachers play an active role in promoting students’ physical exercise, mastering skills, entertaining their body and mind, and producing lifelong PE thoughts by making use of limited classroom time, space, and teaching resources. From the perspective of “control value” theory, this paper analyzes and studies the effectiveness of PE flip classroom, so as to further develop and improve PE teaching evaluation and lay the foundation for the popularization of flip classroom in PE teaching.Effective PE teaching is the application of “effective teaching” theory in PE teaching. It has both the general characteristics of effective teaching and the unique characteristics of PE teaching [11]. Its meaning includes “effective” and “efficient”. Flip-over classroom is under the framework of information technology support and class teaching system. By changing the teaching process of traditional classroom, low-level learning objectives are put forward and students’ cognitive load in physical classroom is reduced to realize the liberation of classroom time and space [12, 13]. This paper uses literature research, investigation, data statistics, experience summary, and other methods to implement the effectiveness of flip classroom into PE classroom teaching in schools, based on pedagogy, psychology, and other theories. In addition, observe and investigate the students, as well as research the effectiveness of flipping the classroom. To get the new direction of PE education application flip classroom teaching mode, try to sort out the correlation between PE teaching and flip classroom.


## 2. Related Work

Reference [14] believes that the effectiveness of PE teaching is mainly reflected in the degree of students’ achievement of PE teaching objectives within the specified classroom teaching time. The higher the degree of achievement, the more effective PE teaching is. On the contrary, it is ineffective or inefficient. Reference [15] puts forward that sports skills are the main carrier to achieve the objectives of PE curriculum, and the content design of PE curriculum must take sports skills learning as the main body. Reference [16] survey found that the physical fitness test data that the school spends a lot of time on students every year is only stored in the computer as data. Most students are not clear about their physical fitness, and the test result information is rarely fed back to students in time. In addition, because students lack correct evaluation ability, this information is not of great significance to themselves. According to reference [17], the field of motor skill learning serves as a vehicle for achieving the goals of other learning fields. Other learning fields will become trees without roots and water without a source if there is no sports skill learning field, and the characteristics of this course will be lost, as will the overall health goal of “body, mind, and society.” In order to realize the multiple educational values of PE teaching, reference [18] believes that students should be able to achieve the goals of sports participation, mental health, and social adaptability through the learning of sports skills in the PE classroom. According to research published in reference [19], the physical condition of Chinese teenagers has deteriorated in recent years. This fact has piqued the interest of our government and other relevant leaders. Reference [20] research shows that there are many declining trends in the physical health status of teenagers in China, with one of the most important reasons being the failure to cultivate good PE habits in teenagers and the inability to use scientific methods or means for extracurricular exercise. Reference [21] proposes that data mining technology be used to accurately show many aspects of PE score analysis of higher vocational students from a quantitative perspective, in order to assist teachers, students, and PE teaching departments in formulating appropriate measures. It is beneficial to the development of students’ PE exercise habits, the promotion of a healthy physique, and the effectiveness of PE instruction. References [22, 23] put forward that paying attention to the benefits of teaching requires teachers to have the concept of time and benefits and pay more attention to measurability or quantification. Teachers need to have a sense of reflection, and effective teaching is also a set of strategies. Reference [24] proposed that we should reasonably use progressive teaching evaluation to stimulate students’ enthusiasm in learning sports skills. Reference [25] believes that the improvement of sports skill level in PE teaching is conducive to the development of physical fitness. At the same time, it also plays a direct and important role in promoting students’ normal growth and development and improving students’ health. Moreover, the development of physical fitness also further promotes the improvement of sports skills. The two complement each other. Reference [26] formulated the standard of PE classroom teaching effectiveness in senior high school in combination with other relevant factors of PE classroom teaching. Under the guidance of the new curriculum idea, PE teachers in senior high school have a full understanding and profound understanding of the important links of PE teaching, such as the establishment of teaching objectives, their own teaching ability, the control and management of teaching activities and teaching process, and teaching feedback. The research will be carried out in the investigation of PE curriculum in schools, apply the teaching method of flipped classroom to PE classroom, and comprehensively study the performance of students in flipped classroom teaching of PE curriculum in terms of self-efficacy, technical acceptance, motivation, and emotion recognition [27], so as to lay a solid foundation for demonstration. This study analyzes the current situation of PE teaching in schools and the factors affecting effective teaching from the perspective of effective teaching in PE flip classroom and makes theoretical reflection on the problems existing in the practice of PE flip classroom teaching in schools, which will promote the development of teaching theory to a certain extent.


## 3. Methodology

### 3.1. “Flipped Classroom” Teaching Model

The essence of flip classroom is to maximize the use of face-to-face classroom teaching time to promote students’ deep learning. The construction of “flip classroom” mode is a subversion of the traditional PE education mode in classroom, which really starts students’ learning ability of autonomy, cooperation, and inquiry, makes students’ classroom time more abundant, and also allows students to participate more in the exchange and discussion of PE learning [28]. In the cognitive learning stage of motor skills, facing completely unfamiliar action tasks, students need to know the characteristics and action process of the learned motor skills roughly through a large amount of information, so as to form internal action images and correct action concepts and lay the foundation for formal practice [29]. Children typically use visual representation to encode stimulus information at this age, whereas adults frequently associate visual representation with words to encode information together. “Using video, computer courseware, and other multimedia-assisted teaching in sports skill teaching based on image perception is a clear development trend,” according to the report, which can be achieved by flipping the classroom and information platform. PE teachers can provide visual information such as technical action pictures and sports skill demonstration videos, action demonstrations of teachers and high-level athletes, technical action application scenes and main feature introduction videos through various information platforms and means prior to the start of the new classroom teaching, supplemented by necessary illustrated summary materials and online assessment, and some of them are prepositioned in the cognitives.With the upgrading of modern science and technology, students’ learning styles are more colorful. In particular, when the Internet and multimedia are introduced into PE teaching, teachers’ teaching becomes more comfortable, and the “flip classroom” mode becomes more convenient [30]. In the learning project of flip classroom, we mainly cultivate students’ autonomous learning, obtain relevant learning content through various channels, and sort out relevant knowledge by searching and exploring in person. In teaching, students search and download PE learning knowledge points through the Internet platform website and search and learn according to their own weaknesses in many aspects, without being interfered by others. Students have changed from passively accepting PE knowledge to actively exploring learning methods, and teachers’ identities have also changed into guides for making learning plans and tutors for improving learning environment.Based on the discussion of related theories and related elements’ research status and theoretical achievements, this paper makes quantitative and qualitative analysis on each element of flip classroom teaching of PE course for students. By analyzing the four factors that affect learning effectiveness, starting from self-efficacy, and through the relationship between control and value, the model construction is obtained. Flip classroom research framework is shown in Figure1.Figure 1
The overall framework of flipped classroom based on mobile edge computing-driven neural network.There is a big difference between “flip classroom” mode and traditional PE classroom teaching mode. The most difficult pain point of PE teaching in the past is that it is difficult for students to smoothly transition from the generalization stage of motor skills to the differentiation stage. Flip-over classroom passes part of the precognitive learning stage of motor skills, which reduces the time for explaining in class and increases the time for students to experience and practice motor skills without changing the teaching time. Teachers can give students more personalized guidance and organize students to carry out more abundant practice forms. At the same time, in the classroom, teachers can publish practice guides and test standards through the information-based teaching platform, and students can submit practice video assignments, which can effectively achieve accurate classroom practice and record students’ learning process and help PE teachers to carry out process assessment.In the process of teaching, students will reflect the advantages and disadvantages of teachers’ teaching methods. Teachers should ensure the existence of certain teaching, so as to better guide students’ grouping, group task division, and learning. Teachers should ask students to preview new knowledge points before class, effectively record difficult problems, and put forward in class that teachers can have more time to answer questions and give personalized guidance to difficult problems. Both teachers and students should adapt to the new learning method of flip classroom, but students are the main body of teaching. Participating in teaching through learning is the key to students’ learning, and watching videos, searching materials, and discussing with each other are essential processes in this mode. In the process of learning and developing flip class, giving full play to students’ subjective initiative and improving students’ sense of self-existence are the keys to promoting students’ learning and improving feedback.


### 3.2. Evaluation and Analysis of PE Flip Classroom Teaching Effectiveness

PE teaching process is not only a process of imparting sports knowledge but also a process of learning sports skills. Sports skill learning is a kind of learning based on physical activities, and it is one of the main means to achieve learning goals in other fields. Sports skill learning field is the main learning field of PE and health courses, which together with sports participation field can best embody the course nature of “taking physical exercises as the main means.”PE teaching effectiveness means that PE teachers can achieve better teaching results with less time and energy in order to better help students in physical quality, basic knowledge, technology, skills, and other learning tasks, so as to achieve the established teaching goals. The overall design stage’s most important task is to figure out how the system abstractly performs the predetermined functions. As a result, the overall design stage is divided into two parts. First, the system design envisions several reasonable sprint implementation schemes to complete the system functions, starting with the data flow diagram, and then the software structure design, or the modularization of the system functions, primarily determines which modules the system consists of and how to realize the dynamic call relationship among these modules. Figure2 represents the system’s zero-layer data flow diagram. The zero-layer data diagram, as seen in the diagram, depicts how the data input is processed and the final result in great detail.Figure 2
System zero-layer data flow diagram.In PE teaching, both teachers’ teaching and students’ learning must achieve certain effects, achieve certain purposes, and meet certain needs through teaching activities. For the “flip classroom” mode, it is also very important for PE teachers to focus on ordering knowledge points in class. At this stage, students put forward their own problems and ideas, hoping to get guidance from PE teachers. In classroom teaching, teachers focus on internalizing knowledge and improving skills and integrating knowledge points through teacher-student exchanges. In the classroom of “flipping the classroom” mode, teachers need to have an accurate grasp of the teaching purpose, collect and integrate the difficult problems of the whole students, and sort out the correct solutions.The information transmitted in the source includes a limited number of mutually exclusive and complete events, all of which appear with a certain probability, expressed by a mathematical formula: a group of eventsX1,⋯,Xr, appearing with a predetermined probability pX1,⋯,pXr, and its average value is HX is the information entropy, and its value is equal to the mathematical expectation of the amount of information IX of each event, namely,
(1)HX=−∑r=1rpXiIXi=−∑r=1rpXilogpXi.There is a multi-index evaluation system composed ofn evaluated objects u1,u2,⋯,un and m indexes x1,x2,⋯,xm. xij=xjxii=1,2,⋯n;j=1,2,⋯m is the observed value of the evaluated object ui with respect to the indicator xj. The evaluation data matrix can be expressed as
(2)A=xijn×m=x11x12⋯x1mx21x22⋯x2m⋯⋯⋯⋯xn1xn2⋯xnm.Among them,m, n≥3, and the data in A is the preprocessed normalized data. We describe the PE teaching evaluation process as a general transformation:
(3)yi=fxi1,xi2,⋯,xin,i∈N,where f is a positive transformation function. yi is the comprehensive evaluation value of ui of the evaluated object. Sort u1,u2,⋯,un according to the y1,y2,⋯,yn value from large to small to complete the comparison of the advantages and disadvantages of u1,u2,⋯,un.Self-efficacy is a concrete manifestation of the students’ control dimension; acceptance and motivation for classroom technology are a concrete manifestation of the curriculum value dimension. We will investigate the relationship between factors while studying students’ performance in all aspects of PE course flip classroom learning. Students’ perceived ease of use, perceived usefulness, and willingness to use are analyzed through the establishment of the model to assist teachers in understanding students’ learning situations in the flip classroom situation of PE curriculum, thereby encouraging teachers to improve teaching strategies and teaching methods, fully arousing students’ learning motivation, and thus improving the teaching effect of PE classroom.The amount of information required for a decision tree to make a correct classification judgment on an example is(4)EE=−PP+NlogPP+N−NP+NlogNP+N.If attributeA is taken as the root of the decision tree, A has v values, and it divides E into v subsets EiE1,E2,⋯,Ev. Assuming that V1,V2,⋯,Vv contains Pi positive examples and Ni negative examples, the information entropy of the subset Ei is
(5)EEi=−PiPi+NilogPiPi+Ni−NiPi+NilogNiPi+Ni.The information entropy after classification with attributeA as the root is EA:
(6)EA=∑r=1vPi+NiP+NEEi.Therefore, the information gainEA rooted at the attribute is
(7)IA=EE−EA.Experience in PE teaching includes three aspects: first, the experience of survival process. Reproduce the occurrence process of knowledge and the development process of thinking, so that students can experience the “production process” of knowledge, realize the fun of exploration, discovery, and personal experience, and educate students on realistic attitude, exploration spirit, and scientific thinking method. Second is the rest of curriculum culture. Through the docking of teaching content and real life, the docking of students’ emotions and the outside world, and the docking of original experience and fresh experience, we can create a teaching situation of mutual interest and interest. The third is the experience of innovative activities. Choose learning content that can arouse students’ thinking and inquiry, cultivate students’ innovation, and make students actively exercise in finding, analyzing, and solving problems.For any two evaluated objectsui′,ui",i′,i"∈N,i′≠i", let ωj∗i′,i" be a random variable that obeys a certain distribution on the interval minωi′j,ωi"j,maxωi′j,ωi"j. Call sui′>ui" the superiority of ui′ over ui". Have
(8)sui′>ui"=pfui′>fui"+0.5pfui′=fui".In the formula, the aggregate function represents the event probability as(9)fui′=∑j=1mλi′ωj∗i′,i",(10)fui"=∑j=1mλi"ωj∗i′,i".In PE classroom “flip classroom” teaching mode, it is very important for PE teachers to prepare classroom resources before class. First of all, PE teachers should make teaching contents according to the syllabus and know the teaching purpose of each class well, so as to ensure that “flip classroom” can be carried out in an orderly manner and the teaching tasks can be successfully completed. Teachers can also refer to the content of the “three-dimensional integration” teaching platform in teaching design and modify the teaching implementation plan appropriately so that the teaching process can develop harmoniously at all stages.Next, this paper transmits the data of each course and the teaching situation of each classroom to the central device through the mobile computing device and uses the neural network to evaluate the teaching effect.

## 4. Result Analysis and Discussion

To improve the effectiveness of PE flip classroom teaching, we should improve the effectiveness from several links, such as preparation before class, classroom organization, and practice after class. The effectiveness of sports skill teaching is the main component of PE classroom teaching effectiveness, and its teaching effectiveness greatly affects the promotion of PE teaching effectiveness. Facing the dispute of “weakening or strengthening sports skill teaching” that still exists in deepening PE curriculum reform, we should strive to maximize the face-to-face time between teachers and students in PE classroom teaching and improve the effectiveness of sports skill teaching on the basis of following the inherent law of sports skill formation, so as to realize the multiple educational values of PE teaching. In this experiment, 160 students were randomly selected to get the data for the experiment, and the graph between students’ learning enthusiasm and the effectiveness of flipping classroom was obtained, as shown in Figure3.Figure 3
Students’ learning enthusiasm and the trend of reversing classroom effectiveness.Figure3 shows that there is a link between academic emotion and effectiveness in PE course flipping classroom teaching, where learning emotion and self-efficacy are important factors in the learning process. The higher the learning emotion, the more stable the learning enthusiasm, and the better the self-efficacy, the better the development and learning of flipping classroom in PE teaching. We should pay attention to students’ interest in learning when teaching sports skills. Teachers of PE should treat students as the primary source of information, paying close attention to their needs, emotions, and psychology so that every student can enjoy learning and achieve success, and encourage students to enjoy PE classes and participate actively in PE activities. Teachers and students can exercise, experience, and master motor skills in independent activities, laying a good foundation for lifelong PE awareness in this way. Teachers’ teaching enthusiasm and students’ academic mood are shown in Figure 4.Figure 4
Teachers’ teaching enthusiasm and students’ academic mood trend.It can be seen from the Figure4 that teachers’ teaching enthusiasm is also positively correlated with students’ academic emotions. Positive attitude will have a positive impact on the curriculum, while negative aspects will make students lose interest in the curriculum. The time domain waveform of data distribution obtained by this algorithm is shown in Figure 5.Figure 5
Time domain waveform diagram of data distribution.With the support of the inverted classroom style, students have completed the generalization of motor skills learning before and during the new class, and through the targeted guidance of teachers in the physical class, the rapid differentiation and preliminary automation of motor skills have been realized, and the theoretical knowledge such as game rules and formation arrangement has also been understood and internalized with the support of the information-based teaching platform and the guidance of teachers so that more classroom teaching time can be used to carry out competitions or teaching demonstrations of different forms and difficulties, truly master and apply motor skills, and realize the improvement of teacher-student face-to-face time. Group experiments are conducted, and the correlation trend among students’ self-efficacy, acceptance of flipped classroom technology, and acceptance of learning content is shown in Figure6.Figure 6
Correlation trend of three variables.It can be seen from the Figure6 that with the increase of class time, there is a significant positive correlation among students’ self-efficacy, acceptance of flipped classroom technology, and acceptance of learning content. PE test project management includes adding, modifying, deleting, and weight setting of project information. The data object of the operation is the test item information table. We compare the accuracy of this evaluation method with that of traditional evaluation methods to verify the effectiveness of this method. The comparison result is shown in Figure 7.Figure 7
Comparison between this evaluation method and traditional evaluation method.It can be seen that this evaluation method has certain advantages in accuracy compared with traditional evaluation methods. The score management mainly includes two parts, namely, the score entry of each test item and the calculation of the total score of the score. The data object of the test score entry operation is the score information table, while the score calculation operation involves the score information table and the score information table. Compare the PE scores of students before and after the flip class, and the comparison results are shown in Figure8.Figure 8
Comparison of PE scores of students.It can be seen from the Figure8 that the PE scores of the students after implementing the flip class are obviously better than those before implementing the flip class, which further proves the effectiveness of implementing the PE flip class according to this strategy.Based on the theory of “control value,” this paper combs the theoretical basis of PE teaching flip classroom from self-efficacy, control dimension, value dimension, academic emotion, and so on and obtains the theoretical framework model of this study. It also designs the whole research process of PE teaching reversing classroom effectiveness. Questionnaire, open-ended questions, interviews, and other quantitative and qualitative research methods are used to collect, sort out, and analyze the research data. The research shows that students are more active in the scale of learning emotion, self-efficacy, acceptance of flip classroom technology, and relevance of learning content. There is also a significant positive correlation between students’ learning mood and their final learning results. In the process of flipping classroom teaching, students have certain requirements for teaching, learning, cooperation, and discussion in the teaching mode of flipping classroom. This need has greatly influenced their learning mood. The PE flip classroom supported by information technology, through the precise design and implementation of online and offline links inside and outside the classroom, can partially advance the cognitive learning stage of motor skills, accelerate the transition from generalization to differentiation stage of motor skills learning, realize the initial automation and normalization of application of motor skills learning, and make better use of the face-to-face time between teachers and students to improve the effectiveness of motor skills teaching.


## 5. Conclusions

Cultivating and stimulating students’ interest in sports and improving the effectiveness of sports skills teaching are based on exploring the laws of students’ physical and mental development and researching students’ interest needs and individual needs. At the same time, in teaching, it is necessary to cultivate middle school students’ sports awareness, mobilize students’ psychology, make the whole learning process full of pleasant and harmonious atmosphere, and provide opportunities for students’ personality development. The effectiveness of classroom teaching is an important issue related to the quality of classroom teaching. One of the plans to improve the effectiveness of physical education classroom teaching is to make our physical education teachers establish the concept of effective teaching and master the strategies of teaching effectiveness. For physical education, the core of classroom teaching effectiveness research is to analyze and explore the nature and law of teachers’ “teaching” and students’ “learning” and their relationship in the teaching process to guide choices. The research in this paper involves mobile edge computing technology, neural network technology, and flipped classroom. Through neural network evaluation results, students can more comprehensively and systematically understand their school effects and adjust their learning plans in time. This paper starts with the formation rules and teaching strategies of motor skills and, on the basis of analyzing the essence and teaching effectiveness of flip classroom, clarifies the mechanism of PE flip classroom teaching effectiveness based on motor skills learning. In order to eliminate PE teachers’ misunderstanding of flip classroom, it can provide theoretical reference for PE course to reasonably use flip classroom to improve PE teaching effect, improve PE course informatization teaching level, and analyze the effectiveness of PE flip classroom teaching.
