## Body

## 1. Introduction

Relevant policies in China propose strengthening the cultivation of international talents. Meanwhile, the outline clearly points out that a group of talents with international vision, familiar with international rules and able to participate in international affairs and international competition, should be cultivated [1, 2]. With the development of global economic integration, more and more IT companies and II enterprises in China are actively exploring the international market. Therefore, the importance of cultivating IT talents suitable for the international market for China is increasingly prominent [3].The IT talents required by the international market should not only have solid professional knowledge but also have the ability to communicate professional knowledge in cross-cultural context using English fluently. IT English courses in colleges and universities aim to cultivate students’ ability to use foreign language to learn professional knowledge and solve professional problems. Meanwhile, they also focus on improving students’ ability to use foreign language to communicate and communicate professional knowledge [4, 5]. IT English is an important course to train students to read and understand the software engineering industry, which can improve students’ ability to write English software development documents and oral English communication in the environment of project development, so as to make students more competitive in international software companies after graduation [6].At present, as far as the status quo of higher education in China is concerned, the IT English teaching in most colleges and universities still adopts the traditional “teacher-oriented” cramming teaching mode, which leads to the general deficiency of students’ comprehensive professional English application ability, teamwork ability, and oral expression and communication ability. The main reason for this is that China’s current professional English teaching materials have many problems, such as the disconnection between the content of the teaching materials, the teaching mode of the courses, and the actual project development [7]. In this situation, in order to promote the training of international IT talents, the innovative research on the teaching mode and method of IT English classroom is a new topic that needs to be studied urgently [8].In today’s international context, how to promote the IT English course teaching method reform and optimization is very urgent and significant, and IT English teaching reform is a new challenge and opportunity. Therefore, this paper studies the flipped classroom teaching mode of IT English based on SPOC in order to improve the teaching quality of IT English and cultivate more IT talents for the society. The following are the key contributions of the proposed study:(i)

## 2. IT English Flipped Classroom Teaching Mode

### 2.1. Status Quo of IT English Teaching

The contradiction between the IT market’s demand for high-quality talents and the unsatisfactory status quo of IT English teaching requires that the unsatisfactory status quo of IT English teaching be changed and the causes of the unsatisfactory status quo of IT English teaching be analyzed in order to realize the change [9].(1)
There is a big difference in the quality of students and their learning quality is not high.Students’ learning foundation and learning attitude affect the teaching effect of IT English to a great extent. When students come to school, their English level is uneven. In order to facilitate teaching, teachers often set uniform goals in teaching and adopt the same teaching methods for all students. This led to some interesting learning for students who could keep up. However, students who cannot keep up with IT English will hold a fear of difficulties, and the more afraid they become, the more difficult they become, and the result is that they simply give up [10, 11]. In addition, students’ learning attitude is not correct. They think that as long as they learn professional courses well, IT English is not important. Of course, some students want to learn IT English well, but they fail to balance the time between IT major and IT English, so that they fail to learn IT English persistently [12].(2)
Teachers do not have advantages in quality, and knowledge and methods are updated slowly.The IT industry is originally a new industry; there have been no normal colleges to train IT English major teachers, generally computer or English major teachers through advanced study or training to lead the course. Therefore, the basic quality of teachers does not have a great advantage. In addition, with the rapid development of IT industry and the rapid updating of knowledge, teachers are required to update knowledge regularly and in a planned way, but schools and society fail to create a good platform for teachers to update their knowledge [13].(3)
The content of the textbook lags behind the actual development of IT industry English.A good teaching effect must rely on good teaching materials, and a good set of teaching materials often need a long period of time to be produced, but the IT industry develops rapidly and the industry language vocabulary is updated quickly, so the IT English teaching materials often cannot keep up with the development of the IT industry [14].


### 2.2. IT English Flipped Classroom Teaching Mode Based on SPOC

In 2013, Professor Armando Fox of the University of California at Berkeley proposed SPOC (small private online course). SPOC can not only supplement classroom teaching but also completely replace classroom teaching. It can improve the utilization of classroom and improve students’ learning ability and students’ participation. By definition, SPOC’s small corresponds to MOOC’s massive and private corresponds to open. It can be seen that MOOC is mainly aimed at learners from all over the world, while SPOC pays more attention to learners on campus. Flipped classroom refers to readjusting the time inside and outside the classroom and transferring the decision-making power of learning from teachers to students. In this kind of teaching mode, with precious time in the classroom, students can focus more on active project-based learning and jointly study and solve the challenges of localization or globalization and other real-world problems, so as to obtain a deeper understanding. The basic idea of SPOC based IT English flipped classroom teaching mode is to make use of excellent MOOC teaching resources, change the traditional teaching mode, promote blended teaching and student participation, and further improve the teaching quality [15, 16].The main purpose of this paper is to make high-quality MOOC resources effectively used in IT English teaching through SPOC and flipped classroom, so as to improve the teaching efficiency. IT English flipped classroom teaching mode includes three parts. The first part is the teacher’s preparation before taking this course, including setting course objectives, learning MOOC in advance, selecting high-quality MOOC, collecting learning materials, uploading relevant resources, and doing a good job in teaching design. The second part is the teaching process of a specific teaching unit [17], including before class, in class, and after class, cycle, until the end of the course. The third part is through the construction of teaching quality evaluation model, in order to obtain the evaluation results of IT English flipped classroom teaching mode, in order to improve the existing teaching mode and improve the teaching quality [18].


#### 2.2.1. Teacher Preparation

Before the beginning of the semester course, although the teaching of knowledge points can be replaced by MOOC teaching video, instead of preparing lessons like traditional teaching, teachers need to prepare carefully in advance in the face of new teaching methods. The specific process is shown in Figure1.(1)
According to the syllabus and students’ prior knowledge, teachers set the curriculum objectives and unit teaching objectives.(2)
Learn MOOC in Advance. At present, colleges and universities are not the main body of the construction of MOOC, and teachers are not the creators of the course. Therefore, in order to choose the appropriate MOOC, we need to learn the relevant MOOC courses in advance.(3)
Choose High-Quality MOOC. The existing MOOC resources are very rich, so teachers need to consider many aspects in the selection, such as the teaching objectives of the courses taught, the content of the textbooks used, and the students’ knowledge level to select the most suitable MOOC [19].(4)
Collect Learning Materials. Before the class, teachers should record supplementary videos in advance, because the original purpose of MOOC is not just to let the students in the class learn nor is it based on the teaching materials stipulated by our school, so teachers need to be prepared for the parts of teaching videos that do not involve the contents of teaching materials. In addition, we should prepare learning materials for students to read, such as books, websites, and electronic materials, so as to give students more choices of learning resources.(5)
Do a Good Job in Teaching Design. The in class stage is carried out in the classroom environment. But students are the main body of the classroom, and teaching activities and students’ learning activities are very different. Teachers need to change the previous teaching design, from the teaching objectives, teaching process, and other aspects of detailed teaching design; the effect of teaching design directly affects the students’ complete construction of the course content. The preparation of teachers is the key to flipped teaching in SPOC environment. The five links mentioned in this section require teachers to work hard. The more well-prepared the teachers are in the five links, the smoother the IT English course will be and the better the effect will be [20].Figure 1
Preparation process of teachers.


#### 2.2.2. Implementation of Unit Teaching

IT English course consists of many teaching units. The so-called unit teaching is a relatively complete unit of knowledge teaching; unit teaching can be a chapter or a section of the course or a knowledge point or a lesson. We divide a unit teaching process into preclass, in class, and after class.(1) Preclass Stage. The preclass stage is the knowledge imparting stage of this teaching mode. Teachers prepare IT English teaching videos and resources on SPOC platform in advance, and students carry out autonomous learning. In this stage, both teachers and students need to complete many learning links. The specific process of preclass stage is shown in Figure 2.Figure 2
Specific process of preclass stage.For IT English teachers, they should first set the teaching objectives of the unit according to the curriculum objectives and syllabus and then compare the selected MOOCS with the teaching materials in detail. If the teacher only publishes similar contents when arranging MOOCS resources but does not match the teaching materials, some students will feel that they do not want to learn or some of the knowledge points in the original MOOCS video cannot be easily understood, which will inevitably reduce students’ interest in learning. Therefore, teachers should carefully review the teaching content every week. For the knowledge points not involved in the original MOOCS, teachers should record teaching videos or use other authorized video resources. At the same time, in order to make students better understand the knowledge points, teachers can add some other forms of IT English learning resources (e.g., learning website links, e-books, case materials, etc.) on SPOC platform for students to learn. At the same time, according to the content of the teaching materials, teachers should check and adjust the classroom tests on the original MOOCS and carefully design them. In addition, teachers should participate in the interaction with students before class, try to reply to students as soon as possible, and answer questions online for students. In this process, teachers can also learn the students’ mastery of knowledge points, which knowledge is difficult or has been mastered, which students master better, and which students have difficulties in learning. Teachers should make full use of the benefits of discussion. For students, they should first understand the teaching objectives of the unit and then register and log on to SPOC platform to watch the IT English teaching videos of the unit in the selected MOOC, browse various resources, and complete the classroom test according to the requirements of MOOC. It is worth noting that MOOC platform provides online discussion, which can solve the cognitive construction of students’ basic knowledge. When students encounter problems that cannot be solved in their study, they can publish topics in the discussion area. Students can help each other to answer them. Generally, some basic knowledge problems can be effectively solved. In the discussion area, students can also publish their feelings about the learning of this unit. For example, after learning on the platform, they cannot deeply grasp some knowledge points, and they hope that teachers can further explain and discuss them in class. This is also for teachers to better grasp the learning situation of students on the MOOC platform and id conducive to the development of teaching activities.(2) In Class Stage. The in class stage is the complete knowledge construction stage of IT English curriculum model. In the classroom environment, students should not only master the knowledge completely but also cultivate their abilities in all aspects, such as the ability to solve comprehensive problems independently and creative thinking ability. Therefore, the in class stage is divided into two parts: one part is to discuss the key and difficult points and clarify the knowledge points, so that students can systematically perceive the knowledge points of this class, and construct the knowledge completely, so as to better consolidate the knowledge; the other part includes the activities of raising questions, thinking alone, determining problems, small group discussion, reporting and communication, teachers’ puzzles, and summary and evaluation. In this process, we should firmly grasp the knowledge points and improve the ability of comprehensive application. The specific process of the in class stage is shown in Figure 3.Figure 3
The specific process of the middle class.For teachers, first of all, at the beginning of the IT English class, they spend less time with students to discuss the important and difficult points of the content learned in the class, understand the questions that students have not solved and the knowledge points that are difficult to understand, and sort out the content and knowledge points as a whole to help students complete the construction of knowledge. Then most of the rest of the class time is used to cultivate students’ comprehensive ability. In order to cultivate students’ ability to use knowledge to analyze and solve problems, teachers need to put forward multilevel comprehensive problems. One is slightly more difficult than the general problems, so as to improve students’ understanding of unit knowledge. The other is the problem of the comprehensive use of knowledge points, which is used to cultivate students’ comprehensive problem-solving ability and improve their high-level thinking. Let the students think independently first. If they cannot solve the problem by themselves, organize the students to discuss these problems in groups. After listening to the students’ reports, if the problems have not been effectively solved, the teacher needs to give detailed answers. Finally, according to the classroom situation, the teacher made a summary. For students, first of all, they need to actively participate in the process of discussing important and difficult points and knowledge points with teachers and consult the teachers about the problems they fail to understand in MOOC learning, so as to actively complete the knowledge construction. Then, I will think independently of the questions raised by the teacher and try to solve the problems with the knowledge I have learned in the MOOC. If I cannot solve the problems independently, I will discuss them in groups and actively communicate with my classmates. In the reporting section, students should make a report boldly, raise the problems encountered by the group in the discussion process, and listen carefully when the teacher explains the problems and summarizes them, so as to improve their knowledge and ability points.(3) The After Class Stage. IT is stage after class English teaching mode of study effect test stage, in order to get more accurate results, in addition to the original reference for design of a lesson homework exercises, the teacher on the homework and unit test according to the difficult point problem sets, and knowledge to design to measure whether the overall level of students reached the standard of learning into the next unit. The specific tasks and activities of teachers and students in the after class stage are shown in Figure 4.Figure 4
Specific tasks and activities of teachers and students in the after class stage.For teachers, they should first complete relevant exercises and tests. On this basis, according to the IT English teaching objectives of this unit, homework and unit test questions should be designed from two aspects of knowledge and ability. It is worth noting that, in order to grasp the actual level of students, according to the teaching practice, teachers should appropriately select some topics beyond the teaching objectives when designing homework and unit tests. It is important to point out that students in classroom testing cannot only rely on the class assignments and unit tests they originally desired. This is because the original students who desire classroom teaching are a large number of learners with very different levels of knowledge in all aspects of the world. If you blindly rely on these, you will not be able to accurately understand the real learning situation and effect. Teachers analyze the results of unit tests to give personalized guidance to students who fail to reach the teaching objectives. For students, first of all, they need to complete the homework and unit tests on the SPOC platform, give feedback to teachers to solve the wrong exercises in the homework and tests, and review them accordingly. At the same time, they actively discuss with classmates, help each other, and constantly master and consolidate the knowledge.


#### 2.2.3. Teaching Quality Evaluation Method

The third part is to obtain the teaching quality evaluation results of IT English flipped classroom through the construction of teaching quality evaluation model, in order to improve the existing teaching model and improve the teaching quality. The flipped classroom teaching of IT English is affected by a variety of factors, each of which has different influence on the teaching effect, so IT is difficult to establish an accurate mathematical model. Let the teaching quality evaluation index of IT English flipped classroom bex1,x2,…,xm. The first step to establish the teaching quality evaluation model of IT English flipped classroom to establish an evaluation index system. A reasonable and scientific evaluation index system can improve the accuracy of teaching quality evaluation, but the teaching quality evaluation is affected by a variety of factors, for example, teaching method, teaching attitude, teaching content, and management and teaching effect, and the evaluation index system of teaching quality was established by referring to relevant literature and research, and then the hierarchical method was adopted to analyze and establish the teaching quality evaluation index system, as shown in Table 1.Table 1
Teaching quality evaluation index system.
Level indicatorsSecondary indicatorsTeaching contentTeaching objectives (x1)Scientific nature of teaching content (x2)Teaching key and difficult points processing (x3)Teaching methodGood at heuristic thinking (x4)Taking care of personality differences (x5)Learning method guidance (x6)Teaching tools and means (x7)Teaching attitudeCourse preparation (x8)Degree of engagement (x9)Personal quality of teachers (x10)Teaching effectTeaching plan completion (x11)Students’ mastery of the teaching content (x12)When using big data technology to calculate the weight value of teaching quality evaluation index of IT English flipped classroom, Hadoop computing mode is used to calculate the evaluation weight value according to the analytic hierarchy process. First, the judgment matrix is constructed, and the judgment matrixW is expressed as(1)W=wijn∗n,where n is the number of horizontal and vertical lines in the matrix, and wij is the degree coefficient, which is generally as in [1, 10]. Therefore, for formula (1) above, the degree of influence can be expressed as(2)wji=1wji,i,j=1,2,…,n.Normalize the data of each column in judgment matrixW to get matrix W′, add each row of W′ according to the row to get vector w, use the sum product method to find the maximum eigenroot of the vector, and get(3)λmax=1n∑i=1nW⋅wTwij,where λmax is the maximum characteristic root and T is the coefficient of the summation product method. Using the random consistency ratio CR to judge the consistency of the largest characteristic root, the following calculation can be obtained:(4)CR=CIRI,whereCI is the consistency index and RI is the average random consistency index. Therefore, the weight value of the final teaching quality evaluation index can be calculated according to the consistency index:(5)CI=λmax−nn−1.In the above formula,n is the order of the judgment matrix. Formulas (3) and (5) are put together, and the comprehensive random consistency table finally obtains the following: When matrix W meets CR<0.1, the characteristics of the normalized vector can be used as a weighted vector; the final calculation result of formula (2) is the weight of the teaching evaluation index, and the calculation process is repeated to calculate the application-oriented undergraduate teaching evaluation index and its weight value K=k1,k2,…,km; then the mathematical expression of teaching quality evaluation model is(6)y=fk1x1,k2x2,…,kmxm.In the formula,f represents the evaluation function.The teaching quality evaluation model mentioned above is used to evaluate the teaching quality evaluation of IT English flipped classroom, and the corresponding evaluation results are output, in order to improve the existing problems of IT English flipped classroom teaching model and further improve the teaching quality.

### 2.2.3. Teaching Quality Evaluation Method

The third part is to obtain the teaching quality evaluation results of IT English flipped classroom through the construction of teaching quality evaluation model, in order to improve the existing teaching model and improve the teaching quality. The flipped classroom teaching of IT English is affected by a variety of factors, each of which has different influence on the teaching effect, so IT is difficult to establish an accurate mathematical model. Let the teaching quality evaluation index of IT English flipped classroom bex1,x2,…,xm. The first step to establish the teaching quality evaluation model of IT English flipped classroom to establish an evaluation index system. A reasonable and scientific evaluation index system can improve the accuracy of teaching quality evaluation, but the teaching quality evaluation is affected by a variety of factors, for example, teaching method, teaching attitude, teaching content, and management and teaching effect, and the evaluation index system of teaching quality was established by referring to relevant literature and research, and then the hierarchical method was adopted to analyze and establish the teaching quality evaluation index system, as shown in Table 1.Table 1

First, the judgment matrix is constructed, and the judgment matrixW is expressed as(1)W=wijn∗n,where n is the number of horizontal and vertical lines in the matrix, and wij is the degree coefficient, which is generally as in [1, 10]. Therefore, for formula (1) above, the degree of influence can be expressed as(2)wji=1wji,i,j=1,2,…,n.Normalize the data of each column in judgment matrixW to get matrix W′, add each row of W′ according to the row to get vector w, use the sum product method to find the maximum eigenroot of the vector, and get(3)λmax=1n∑i=1nW⋅wTwij,where λmax is the maximum characteristic root and T is the coefficient of the summation product method. Using the random consistency ratio CR to judge the consistency of the largest characteristic root, the following calculation can be obtained:(4)CR=CIRI,whereCI is the consistency index and RI is the average random consistency index. Therefore, the weight value of the final teaching quality evaluation index can be calculated according to the consistency index:(5)CI=λmax−nn−1.In the above formula,n is the order of the judgment matrix. Formulas (3) and (5) are put together, and the comprehensive random consistency table finally obtains the following: When matrix W meets CR<0.1, the characteristics of the normalized vector can be used as a weighted vector; the final calculation result of formula (2) is the weight of the teaching evaluation index, and the calculation process is repeated to calculate the application-oriented undergraduate teaching evaluation index and its weight value K=k1,k2,…,km; then the mathematical expression of teaching quality evaluation model is(6)y=fk1x1,k2x2,…,kmxm.In the formula,f represents the evaluation function.The teaching quality evaluation model mentioned above is used to evaluate the teaching quality evaluation of IT English flipped classroom, and the corresponding evaluation results are output, in order to improve the existing problems of IT English flipped classroom teaching model and further improve the teaching quality.


## 2.2.1. Teacher Preparation

Before the beginning of the semester course, although the teaching of knowledge points can be replaced by MOOC teaching video, instead of preparing lessons like traditional teaching, teachers need to prepare carefully in advance in the face of new teaching methods. The specific process is shown in Figure1.(1)
According to the syllabus and students’ prior knowledge, teachers set the curriculum objectives and unit teaching objectives.(2)
Learn MOOC in Advance. At present, colleges and universities are not the main body of the construction of MOOC, and teachers are not the creators of the course. Therefore, in order to choose the appropriate MOOC, we need to learn the relevant MOOC courses in advance.(3)
Choose High-Quality MOOC. The existing MOOC resources are very rich, so teachers need to consider many aspects in the selection, such as the teaching objectives of the courses taught, the content of the textbooks used, and the students’ knowledge level to select the most suitable MOOC [19].(4)
Collect Learning Materials. Before the class, teachers should record supplementary videos in advance, because the original purpose of MOOC is not just to let the students in the class learn nor is it based on the teaching materials stipulated by our school, so teachers need to be prepared for the parts of teaching videos that do not involve the contents of teaching materials. In addition, we should prepare learning materials for students to read, such as books, websites, and electronic materials, so as to give students more choices of learning resources.(5)
Do a Good Job in Teaching Design. The in class stage is carried out in the classroom environment. But students are the main body of the classroom, and teaching activities and students’ learning activities are very different. Teachers need to change the previous teaching design, from the teaching objectives, teaching process, and other aspects of detailed teaching design; the effect of teaching design directly affects the students’ complete construction of the course content. The preparation of teachers is the key to flipped teaching in SPOC environment. The five links mentioned in this section require teachers to work hard. The more well-prepared the teachers are in the five links, the smoother the IT English course will be and the better the effect will be [20].Figure 1
Preparation process of teachers.


## 2.2.2. Implementation of Unit Teaching

IT English course consists of many teaching units. The so-called unit teaching is a relatively complete unit of knowledge teaching; unit teaching can be a chapter or a section of the course or a knowledge point or a lesson. We divide a unit teaching process into preclass, in class, and after class.(1) Preclass Stage. The preclass stage is the knowledge imparting stage of this teaching mode. Teachers prepare IT English teaching videos and resources on SPOC platform in advance, and students carry out autonomous learning. In this stage, both teachers and students need to complete many learning links. The specific process of preclass stage is shown in Figure 2.Figure 2
Specific process of preclass stage.For IT English teachers, they should first set the teaching objectives of the unit according to the curriculum objectives and syllabus and then compare the selected MOOCS with the teaching materials in detail. If the teacher only publishes similar contents when arranging MOOCS resources but does not match the teaching materials, some students will feel that they do not want to learn or some of the knowledge points in the original MOOCS video cannot be easily understood, which will inevitably reduce students’ interest in learning. Therefore, teachers should carefully review the teaching content every week. For the knowledge points not involved in the original MOOCS, teachers should record teaching videos or use other authorized video resources. At the same time, in order to make students better understand the knowledge points, teachers can add some other forms of IT English learning resources (e.g., learning website links, e-books, case materials, etc.) on SPOC platform for students to learn. At the same time, according to the content of the teaching materials, teachers should check and adjust the classroom tests on the original MOOCS and carefully design them. In addition, teachers should participate in the interaction with students before class, try to reply to students as soon as possible, and answer questions online for students. In this process, teachers can also learn the students’ mastery of knowledge points, which knowledge is difficult or has been mastered, which students master better, and which students have difficulties in learning. Teachers should make full use of the benefits of discussion. For students, they should first understand the teaching objectives of the unit and then register and log on to SPOC platform to watch the IT English teaching videos of the unit in the selected MOOC, browse various resources, and complete the classroom test according to the requirements of MOOC. It is worth noting that MOOC platform provides online discussion, which can solve the cognitive construction of students’ basic knowledge. When students encounter problems that cannot be solved in their study, they can publish topics in the discussion area. Students can help each other to answer them. Generally, some basic knowledge problems can be effectively solved. In the discussion area, students can also publish their feelings about the learning of this unit. For example, after learning on the platform, they cannot deeply grasp some knowledge points, and they hope that teachers can further explain and discuss them in class. This is also for teachers to better grasp the learning situation of students on the MOOC platform and id conducive to the development of teaching activities.(2) In Class Stage. The in class stage is the complete knowledge construction stage of IT English curriculum model. In the classroom environment, students should not only master the knowledge completely but also cultivate their abilities in all aspects, such as the ability to solve comprehensive problems independently and creative thinking ability. Therefore, the in class stage is divided into two parts: one part is to discuss the key and difficult points and clarify the knowledge points, so that students can systematically perceive the knowledge points of this class, and construct the knowledge completely, so as to better consolidate the knowledge; the other part includes the activities of raising questions, thinking alone, determining problems, small group discussion, reporting and communication, teachers’ puzzles, and summary and evaluation. In this process, we should firmly grasp the knowledge points and improve the ability of comprehensive application. The specific process of the in class stage is shown in Figure 3.Figure 3
The specific process of the middle class.For teachers, first of all, at the beginning of the IT English class, they spend less time with students to discuss the important and difficult points of the content learned in the class, understand the questions that students have not solved and the knowledge points that are difficult to understand, and sort out the content and knowledge points as a whole to help students complete the construction of knowledge. Then most of the rest of the class time is used to cultivate students’ comprehensive ability. In order to cultivate students’ ability to use knowledge to analyze and solve problems, teachers need to put forward multilevel comprehensive problems. One is slightly more difficult than the general problems, so as to improve students’ understanding of unit knowledge. The other is the problem of the comprehensive use of knowledge points, which is used to cultivate students’ comprehensive problem-solving ability and improve their high-level thinking. Let the students think independently first. If they cannot solve the problem by themselves, organize the students to discuss these problems in groups. After listening to the students’ reports, if the problems have not been effectively solved, the teacher needs to give detailed answers. Finally, according to the classroom situation, the teacher made a summary. For students, first of all, they need to actively participate in the process of discussing important and difficult points and knowledge points with teachers and consult the teachers about the problems they fail to understand in MOOC learning, so as to actively complete the knowledge construction. Then, I will think independently of the questions raised by the teacher and try to solve the problems with the knowledge I have learned in the MOOC. If I cannot solve the problems independently, I will discuss them in groups and actively communicate with my classmates. In the reporting section, students should make a report boldly, raise the problems encountered by the group in the discussion process, and listen carefully when the teacher explains the problems and summarizes them, so as to improve their knowledge and ability points.(3) The After Class Stage. IT is stage after class English teaching mode of study effect test stage, in order to get more accurate results, in addition to the original reference for design of a lesson homework exercises, the teacher on the homework and unit test according to the difficult point problem sets, and knowledge to design to measure whether the overall level of students reached the standard of learning into the next unit. The specific tasks and activities of teachers and students in the after class stage are shown in Figure 4.Figure 4
Specific tasks and activities of teachers and students in the after class stage.For teachers, they should first complete relevant exercises and tests. On this basis, according to the IT English teaching objectives of this unit, homework and unit test questions should be designed from two aspects of knowledge and ability. It is worth noting that, in order to grasp the actual level of students, according to the teaching practice, teachers should appropriately select some topics beyond the teaching objectives when designing homework and unit tests. It is important to point out that students in classroom testing cannot only rely on the class assignments and unit tests they originally desired. This is because the original students who desire classroom teaching are a large number of learners with very different levels of knowledge in all aspects of the world. If you blindly rely on these, you will not be able to accurately understand the real learning situation and effect. Teachers analyze the results of unit tests to give personalized guidance to students who fail to reach the teaching objectives. For students, first of all, they need to complete the homework and unit tests on the SPOC platform, give feedback to teachers to solve the wrong exercises in the homework and tests, and review them accordingly. At the same time, they actively discuss with classmates, help each other, and constantly master and consolidate the knowledge.

When the experiment lasted for 9 months, the average score of experimental group A reached the maximum of 69.6, an increase of 3.3 compared with the initial average score of students. However, when the experiment lasted for 12 months, the average score of experimental group B reached the maximum of 81.3, an increase of 14.5 compared with the initial average score of students, indicating that, compared with experimental group A, the average score of experimental group B improved more significantly. It shows that the flipped English teaching mode based on SPOC can effectively improve students’ performance and verifies the effectiveness of this teaching mode.On the basis of the above experiments, the average daily learning duration of students during the experiment period is compared, and the specific results are shown in Table6.Table 6
