## Abstract

There are still a number of issues in college English classes, for example, the learning environment is relatively closed and some teachers lack a sense of innovation and reform, both of which have an impact on students’ ability to improve their English skills. The expansion and application of big data technology in education have piqued the interest of educational researchers, industry and application practitioners, and industry management and decision-makers. This study uses educational data mining technology to model in the mobile edge computing environment, analyze and process, and create an overall design from three levels: teaching design process, learning activity process, and learning results, all based on big data in the smart classroom. The results show that using the algorithm with the interest index, the number of strong rules obtained can be used to derive a concrete relationship between learning behavior factors and learning effect, which can help users improve their learning behavior.

## 1. Introduction

Big data and mobile edge computing in education are a collection of all data that can be used for educational development, which is generated in the process of education or collected according to educational needs [1]. Through modeling, the relationship between students’ learning results and variables such as learning content, learning resources, and teaching behavior is found, and then the future learning trend of students is predicted. The construction of intelligent classroom information platform based on educational big data and the research on teaching and learning application strategies of intelligent classroom have positive reference significance for the majority of front-line teachers and educational researchers and are also conducive to further innovation and exploration in combination with practical work [2, 3].Currently, smart classroom research is primarily conducted from two angles. The first is to investigate how to create a smart classroom teaching environment, how to develop smart classroom applications or product projects, how to build smart classroom terminals, and so on, from the perspective of informatization, to provide hardware and related software technology support for the construction of smart classrooms [4]. The second is to investigate how to design teaching ideas, teaching methods, and teaching processes for a specific course in the existing intelligent learning environment. As an example, students’ grades are considered. Teachers typically analyze and treat students’ grades based on the number of students who receive excellent, good, fair, or poor grades, and the reasons for students' achievements are frequently unknown [5, 6]. Modeling and prediction are done using educational data mining algorithms and learning analysis technology [7–9]. Whichever data mining method [10] is used, the basic idea should be to reflect usability and availability, that is, to design the data collection framework closely following the influencing factors of students' learning and the data of students' behaviors that smart classroom products can obtain.Data mining is a decision-making aid and a method for analyzing large amounts of data. Data mining technology and mobile edge computing, which can comprehensively analyze the hidden internal relations between test results and various factors [11], is unquestionably beneficial when it comes to teaching evaluation. Developing smart classrooms is a good way to contribute to the college English revolution. At the same time, awakening the classroom with wisdom and leading teachers' professional growth is not only the call of the times but also the major mission of college English smart classroom reform in the new era. This study discusses the construction strategy and application of smart classroom in college English course and provides a reference for the breakthrough and transformation of teaching concept and teaching design in college English, a traditional course, based on an analysis of the needs of college English learners and society.


## 2. Related Work

Comparatively speaking, education data mining mainly focuses on finding out the rules, that is, solving the problem of “why and what”; learning analysis focuses on the law of application discovery, that is, the scene of “how to use it.” Literature [12] holds that teachers have changed from traditional classroom masters to creators and providers of high-quality learning environment and favorable learning conditions, while learners have changed from passive receivers to active creators and passive listeners to active practitioners and participants. English teaching wisdom is regarded as the efforts of conceptual planning, experience scheduling, operation design, and so on in English teaching and acts on the initiative of the main body in English teaching practice [13]. Literature [14] holds that every teacher must show a sensitive, rapid, and accurate ability to judge and act in the face of complicated English teaching situations, which is the teacher's English teaching wisdom. Literature [15] holds that wisdom is not just intelligence in the general sense or IQ in the psychological concept, but a kind of quality, state, and realm that covers various qualities and knowledge and experience of individuals. Literature [16] puts forward that for education, educational wisdom is embodied as a kind of quality, state, and realm of education. Literature [17] holds that teaching wisdom is a kind of comprehensive ability that teachers generate when they have deep insight, keen wit, and efficiently respond to English teaching situations in English teaching practice, based on their own understanding of teaching phenomena and teaching theories and achieve the realm of harmony, symbiosis, freedom, and beauty. Literature [18] holds that a smart classroom should be an autonomous classroom, active classroom, emotional classroom, life classroom, and interesting classroom.In recent years, around the common interest that big data can be used to benefit education and learning science, two technologies have been gradually developed, namely, education data mining and learning analysis [19]. Simultaneously, the potential information or association rules obtained through educational data mining have been more widely applied. Most related studies only use a single data mining algorithm to analyze the scores, and the results are not clear enough to be used to guide learning behavior improvement. In the distance education system, a self-adaptive mechanism is used to provide different learning resources and a personalized learning navigation system based on the characteristics of distance learners [20]. The model of personalized service is established by using data mining and knowledge discovery technology in distance education [21]. A method model of learner feature analysis in network distance education is proposed as an application of Web mining in personalized distance education service [22]. Adaptive interactive courses are dynamically generated based on students' interests, abilities, and knowledge levels [23]. These individualized teaching methods are beneficial to students when learning a specific course, but they fall short of the teaching requirements of increasingly comprehensive distance education platforms. Adaptive learning, as proposed in the literature [24], and others, have made fruitful attempts at implementing personalized online learning.


## 3. Research Method

### 3.1. Construction of College English Intelligent Classroom

The analysis and application of big data make it possible for accurate English teaching based on data and achieve the goal of learning before teaching, determining teaching by learning. In the practical application of English teaching in middle schools, the English teaching process of smart classroom includes the common activities of teachers such as “teaching,” “learning,” and their interaction.Based on the construction of high-quality educational resources and information-based learning environment, with the reform of learning methods and educational models as the core, an efficient and interactive English classroom is realized. In today's society, the rapid development of information technology determines the direction of English teaching. Not only by pursuing the accumulation of knowledge and theory but also by paying attention to the training at the scientific level, the ultimate goal of educational practice is achieved. Especially, the perfect combination of information technology and English teaching resources makes the diversity of English teaching possible.Teachers can accurately grasp the first-hand learning information from students through the analysis of students' homework results provided by the information platform of smart classroom, preset the English teaching objectives of this class, and push the preview and test contents of microclass or rich media to students. The big data diagnosis function evaluates students' mastery of English knowledge according to their usual information of class, homework, self-study, and test, which is convenient for students' review and teachers' guidance. Through microclass learning, doing exercises, and participating in discussions, the teachers can know the students' completion, and the students enter the English classroom with thinking and questions, and the teachers bring English teaching activities based on the actual learning situation, which greatly improves the English teaching effect.In the system of college English smart classroom, which consists of teachers' teaching links before, during, and after class, it is equivalent to fully applying dynamic learning data analysis and “cloud, network, and end” to an innovative English teaching process, which also includes various teaching subcategories such as in class and after-class teaching guidance and information platform development [25]. The specific structure is shown in Figure 1:Figure 1
The system structure of college English smart classroom.Teachers' tools provide the basic means of teachers' classroom teaching, mainly including the functions of slide making and projection, microcourse making and publishing, interactive communication and study evaluation, etc., which can be used for arbitrary writing, recording and saving on electronic whiteboard, and realizing the interaction between teachers and students such as task arrangement, homework correction, answering questions and doubts, and individual tutoring. Microclass learning, classroom interaction, homework, and dynamic evaluation are examples of student-side tools that can be used for microclass learning, classroom teacher-student participation, student-student interaction, personalized homework completion, and academic performance checks, among other things.Middle school students have the ability to submit their own questions and opinions at any time, as well as question teachers and spread their ideas. Excellent teacher resources can be found in many provinces, cities, and even across the country. In terms of space, the addition of educational technology, better learning materials, and more study companions can help children in underdeveloped areas start further and have more opportunities for good development, allowing excellent educational resources to benefit more places, sharing the beautiful study life brought by science and technology, and jointly promoting education equity.For the saved time, teachers need to make full use of it, leaving students more abundant time to practice, consolidate, digest and understand new knowledge, communicate with teachers, and solve their own problems. Teachers can also use this time to guide gifted students, middle students, and underachievers and care for every student. Teachers can get English teaching information in time and take necessary measures to make up for the shortcomings in classroom English teaching.


### 3.2. Intelligent Classroom Learning Model Based on Data Mining and Mobile Edge Computing Technology

Data mining is the process of extracting potential and valuable knowledge (models or rules) from a large amount of data. The data mining process is generally divided into four stages as follows:(1)
Data collection (using mobile edge computing device): determining the data source and collecting the required data(2)
Data preprocessing: sorting the collected data into useful data for data mining(3)
Pattern discovery: data mining is carried out on preprocessed data to discover knowledge, rules, and patterns(4)
Pattern analysis: filtering out useless patterns and showing useful potential patterns in a form that people can understandAs the subject of teaching and the object of teaching, students' learning behavior directly affects the cultivation of professional quality and skills. However, as an individual student, due to the differences in educational background, personality, major, etc., his learning behavior is ever changing.Specifically, when carrying out online teaching activities, the network platform is used to carry out teaching activities. Offline activities are mainly based on the traditional teaching mode. Secondly, when building a smart classroom, it is necessary to actively adopt the microclass teaching mode to realize fragmented learning. In the process of classroom teaching, full play is given to the student's dominant position in teaching. Teachers should step down from the authoritative altar and give most of the classroom time to students, so that students can learn independently and discuss freely.Add data mining processing and personalized recommendation modules to the original learning system, as shown in Figure2. The technology of data mining is introduced here, which enables the learning system to consider the learning habits, learning preferences, and learning interests of learners according to the characteristics of students' learning behaviors, instead of just considering the process of knowledge level, so as to better provide personalized learning services.Figure 2
Personalized learning system based on data mining.Learners' learning behaviors have a certain sequence. By visualizing learners' learning behaviors, the approval of the designated student group in the learning behavior is obtained. Taking the behavior category as the node and the behavior association as the edge, a directed graph of behavior paths is constructed, through which we can intuitively get the difference and contrast of the two groups of students’ behavior patterns and then actively serve the formulation of teaching strategies.In the smart classroom, teachers can use the modern teaching platform to record students' learning data, such as chapter study, sign-in, participation in classroom activities, completion of exercises after class, etc., to form a process evaluation basis and finally give a reasonable and effective evaluation, which ensures an open, fair, and just evaluation and arouses students' learning enthusiasm. In order to facilitate the establishment of the decision tree model, this study selects the computer time after class, the degree of understanding of the course before learning, the classroom learning situation, the usual homework situation, and the total score attributes that are closely related to the score attributes as the basis for establishing the decision tree model of total score classification and generates a new basic data table for student score analysis.SupposeSi is the number of samples in category Ci; then, the amount of information needed to classify a given data object is as follows:(1)IS1,S2,⋯,Sm=−∑i=1mpilog2pi,where pi is the probability that any data object belongs to category Ci: pi=Si/S.Let an attributeA take v different values a1,a2,⋯,av. Then the information (entropy) needed to divide the current sample set by using the attribute A can be calculated according to the following formula:(2)EA=∑i=1vS1i+⋯+SmiSIS1j,⋯,Smj.In this way, the information gain obtained by dividing the corresponding sample set of the current branch node by using the attributeA is as follows:(3)GainA=IS1,S2,⋯,Sm−EA.Usually, it is calculated by the sum of squares of cluster center errors of all objects in the data set and their respective clusters. When the sum of squares errors is small enough, it means that the clustering operation can be finished. The expression of the clustering criterion function is as follows:(4)RSS=∑i=1k∑p∈cip−mi2.Here, ci represents the set of i-class data objects, p is the data objects in cluster ci, mi is the average value of cluster ci, and k represents that the data set can be divided into k clusters. Cluster analysis can be used as a module of data mining and a preprocessing step of other mining algorithms.The support degrees is the percentage of X,Y contained in the transaction in D, that is, the probability PX∩Y and its expression are as follows:(5)sX⇒Y=PX∩Y.Therefore, the formula ofonfX⇒Y is as follows:(6)onfX⇒Y=suppX⇒YsuppX.The determining factor is to compare the frequency of a project set with the reference frequency in different project sets to develop the formula of support value. The benchmark frequency of the project set should be assumed to be statistically independent. The factorDF is determined as follows:(7)DFI=PX−PY×PX∪YPXPY.It is used to continuously discuss the basic theory of student behavior in smart classrooms, the design and application of learning analysis tools, the visual design and analysis of learning behavior data, social network analysis, learning evaluation and context based on learning activity process, and so on, through the recording and analysis of student behavior data. Students' portraits are constantly optimized, their preferences are systematically and continuously analyzed, students' personalized learning diagnoses are realized, students' development trends are predicted, and the best learning behavior strategies are explored through behavioral modeling.Teachers assign different assignments based on each student's learning situation and push different learning resources and contents in a personalized push task book. After completing the homework assigned by the teacher, it is turned in to the teacher so that the teacher can get a better understanding of the students' understanding of objective problems. The subjective questions answered by the teachers are reviewed and approved and recorded in the microclass, and a general summary is created based on that information. Internet platform media is learned to use to watch teachers' microlesson video learning knowledge and express their own ideas and opinions in order to achieve communication and information feedback with teachers.

## 4. Results Analysis and Discussion

Only using information technology to make teaching courseware, and simply using multimedia instead of traditional chalk and blackboard as knowledge display carrier, cannot meet the needs of information-based smart classroom construction. When making teaching courseware, that is, copying and pasting the teaching materials directly, it is impossible to flexibly and effectively play the role of multimedia technology and information elements. Students focus on electronic courseware all the time, lacking learning initiative and enthusiasm, thus reducing the effectiveness of teaching.The basic English course is taken as an example. In the interconnected learning environment constructed by the course, there are asynchronous interaction between teachers and students before class, synchronous interaction between teachers and students in class, and asynchronous interaction between teachers and students after class. Preclass teachers use the mobile learning platform to assign learning tasks to students and provide microclass videos, audio materials, video learning materials, tutorial plans, courseware, and other text materials, so that students can conduct personalized autonomous learning according to the task list.In this experiment, the Eclipse environment is used as the platform, Python is used as the development language, and the K-means algorithm is used to cluster the acquired learning features. Firstly, the optimal number of clusters is determined by the clustering criterion function, and the results are shown in Figure3.Figure 3
Number of clusters.As can be seen from Figure3, the curve shows a downward trend, but combined with the actual situation, it can be known that the number of clusters cannot be infinitely small; otherwise, the research significance will be lost.It can also give full play to the role of network information technology, organize students to learn English anytime and anywhere through relevant network platforms and systems, and continuously improve the quality and level of English learning. Classroom incentive system is established, teaching on the basis of completing basic knowledge learning is extended, and certain material rewards are given to students who are outstanding, brave in exploration, and active in innovation, such as notebooks, drinks, and classroom credits.The traditional Apriori algorithm and the improved algorithm with interest degree are used to mine the learning feature data of different types of learners, and the number of association rules obtained is shown in Figure4.Figure 4
Experimental results of different association rule algorithms.The experimental results show that academic achievement is an important embodiment of learning effect, and the relationship between learners' learning behavior and learning effect can be known by analyzing the strong rules related to it.Preset platform learning resources are those that teachers create or set in advance and require students to use. The development of preset curriculum learning resources must adhere to the principles of necessity, sufficiency, and economy, as well as the principles of necessity, sufficiency, and economy. Students of various majors and English levels should be able to choose from a variety of college English presupposition learning resources to meet their individualized, professional, and diverse English learning needs. It covers the teaching requirements and teaching scheme design of English language knowledge, English application ability, students' autonomous learning ability, and core literacy, as well as the college English syllabus and curriculum content system of content science.Because most learners belong to the passive learning type, this study takes passive learners as an example to analyze. Some strong rules of passive learning type are shown in Figure5.Figure 5
Partial unspoken rules.From the confidence level in Figure5, it can be seen that the selected learning features are all important factors that affect academic performance. Furthermore, it can also reflect the rules that may exist in the combination of frequent and minimum rules in university curriculum issues. The results of this study can help school teachers to provide appropriate courses for a certain class of students. In fact, it can help university policymakers understand and improve the current teaching level and improve the overall management process level [6].Despite the fact that teachers and students are in different time zones and locations, the mobile learning platform connects their teaching and learning activities. Questionnaires and tests are used by teachers to assess students' autonomy in learning, and the process can also be supervised by groups or partners. Teachers use platform big data in asynchronous space to manage, guide, and evaluate their students' learning situations. Teachers provide targeted guidance to students in the class based on the learning situation and issues revealed by platform data.The experimental text is obtained by the method of determining factors, and the weights of all association rules will be assigned according to this method. Here, students can choose 8 courses according to the fixed position in the original chart. The actual positioning of each course is set according to the fixed course. Figure6 shows the related rules with the minimum value of 3% in the top ten places.Figure 6
The top ten related rules are arranged in descending order.Due to the contradiction in the curriculum field, the first rule to the fifth rule are rather strange. The sixth rule is very true, because the two projects have similarities in basic requirements. The sixth to tenth rules are more difficult and complicated to explain, because there is no relevant interest in these courses. Therefore, it can be seen that students confuse their interests in the process of choosing university courses.In addition, universities cultivate applied talents, and the teaching objectives of English courses should combine the needs of industries and enterprises to cultivate high-quality and skilled talents, so the teaching resources cannot be static, but must be dynamic and updated at any time. Latest resources and first-hand resources such as real projects of enterprises to teachers and business tutors are introduced.Intelligent push of resources, based on the record and analysis of learning behavior data, can adopt the methods of automatic push and self-subscription of learning resources to intelligently meet the individualized and diversified learning needs of learners. Visualization of teaching, such as modeling, simulation, rendering, augmented reality and other technologies in experimental teaching, visualizes complex experimental processes that are difficult to show.Using UCI data set, the algorithm proposed in this study, ID3 algorithm, and Bayesian algorithm are studied by nonincremental learning, and the experimental data obtained are shown in Figures7 and 8.Figure 7
Algorithm time consumption comparison.Figure 8
Accuracy comparison of algorithms.It can be concluded from this Figure7 that the classification accuracy of incremental decision tree algorithm is 3.65% higher than that of ID3 algorithm.After the teacher assigned the task, the group brainstormed solutions, divided roles and responsibilities, and began mutual learning for learning tasks. Finally, the team will complete and summarize the tasks that each team member is responsible for, and each team will present the results in order to facilitate effective communication and discussion among the teams. Interactive learning also includes group-to-group communication. Students' subjective initiative, control, and evaluation system can be enhanced by using a benign closed-loop system of teaching quality tracking, result evaluation, goal achievement, and information feedback tracking improvement. This provides a strong guarantee for cultivating high-quality talents with the innovative ability and international competitiveness.Online students accept preclass tasks, preview new knowledge, do a good preview test, check preview effect, and find difficult problems. With the help of the platform, group cooperation, mutual assistance, exchange and discussion, work display, full play is given to the advantages of group cooperation, and learning tasks are jointly explored and completed. Teachers in class design teaching, answer questions, initiate discussion activities, exchange views, and solve problems according to the students' learning situation fed back by the platform.In the application of e-learning, the prominent feature is that the knowledge and content displayed on web pages are divided into important factors such as objectives, levels, emphases, and difficulties, so different web pages have different importance. So how to measure the importance of the web page of an online course? These important factors, like traditional teaching, are usually given by teachers or teaching experts in natural language. Therefore, the given semantic evaluation indicating the importance of the web page is converted into a fuzzy set indicating the weight of the web page to measure the importance of the web page. This can not only reflect learners' interest in learning but also be more natural and easier to be understood by people.Using this data set, the algorithm proposed in this study, ID3 algorithm, and Bayesian algorithm are studied incrementally. The experimental data obtained are shown in Figure9, from which it can be concluded that the classification accuracy of this algorithm is higher than that of ID3 algorithm.Figure 9
Time cost and accuracy of the algorithm proposed in this study and ID3 algorithm when increment occurs.At the same time, there are shortcomings of this algorithm, that is, the overhead is larger than ID3 algorithm and Bayesian algorithm. According to the content of the algorithm, this situation is inevitable, because this algorithm mainly focuses on learning the Bayesian classifier parameters of nodes, so it will cost more time.It can meet the requirements of incremental learning. The disadvantage is that it needs extra time, which is understandable. Generally speaking, it can deal with the shortcomings of decision tree algorithm in incremental learning and achieve the expected goal.Teachers' overall curriculum design and concrete implementation, including college English curriculum platform management, monitoring learners' learning behavior, online communication, answering, and counseling, and sorting out feedback information and effective teaching adjustment according to students' feedback information. Students receive learning notices and tasks from teachers, conduct online and offline learning, and cooperate with groups to display learning results.It will provide a broader extension space and achieve higher accuracy for the learning analysis of intelligent classrooms and comprehensively apply learning behavior suggestions or teaching suggestions to many teaching links such as preview before class and searching for new knowledge, through multisource data collection, comprehensive modeling, and intelligent analysis, such as incorporating teachers' and external environment's factors into students' learning analysis.


## 5. Conclusion

The data mining and mobile edge computing model can provide direction for the analysis of students' behavior in the smart classroom, and the smart classroom can obtain ubiquitous information based on different technologies and product architectures. The advantages and disadvantages of various data mining methods are analyzed based on the analysis needs, and a data mining model that meets the analysis needs of student portraits is built, for example. This study collects all-round, multi-angle, and multi-dimensional data and uses educational data mining technology to build models from the perspectives of learners' behavior, learning content, and results, based on the frontier application wisdom classroom of wisdom education. We can determine the special connection in the university courses chosen by students, assist managers in developing teaching and management strategies, and improve students' academic performance by mining the minimum association rules of students' course selection. As a result, teachers should fully exploit the benefits of smart classrooms, create a more engaging learning environment for students, enrich teaching methods, foster a positive learning environment for English, and assist in the reform of smart classrooms in college English.
