The challenges of new economy and new industry have put forward new requirements for the cultivation of engineering talents in China. Based on corpus, this study constructed a model of intelligent English teaching assisted by virtual corpus. The traditional teaching of college English reading is based on, around, and for texts. Using DDL model, teachers can break the limitation of textbooks. On the basis of analyzing the general idea of the text, they can search out massive real corpus related to the general idea of the text by searching the core words in the text, so as to provide extensive reading resources for students in the maximum range. At the same time, teachers can rely on the corpus to design different types of teaching activities, realize student-centered task-based, inquiry-based, and autonomous learning and cultivate students’ critical thinking ability, practical ability, and cross-cultural communication ability. This model breaks the limitation of “classroom + textbook,” realizes student-centered task-based, exploratory, and autonomous learning, trains interdisciplinary new engineering talents needed by emerging industries and new economy in the future, and promotes the sustainable development of English teaching. Corpus-data-driven college English teaching mode breaks the limitation of “classroom + textbook,” changes the traditional college English teaching mode, and realizes student-centered task-oriented, inquiry-based, and autonomous learning.

## Body

## 1. Introduction

Under the influence of globalization, English has become one of the necessary means to communicate with the outside world. Learning English can not only help students to broaden their horizons but also improve their cultural awareness and cultivate their thinking quality, which plays an important role in the development of each student. The rapid progress of modern information technology also provides a faster and more convenient way for English teaching and research [1–3]. Corpus used to retrieve language forms has been promoted in various fields of linguistics because of its rapid and accurate advantages.Data-Driven Learning, referred to as DDL, is an active learning method. It is a “student-centered” discovery learning method, in which students bring questions to the corpus stored with real language use examples to find answers [4]. In this way, students can have a deeper impression on knowledge. From a more realistic language environment, academics can use examples to find themselves learning the use, value, and significance of language, thus improving the effect of foreign language learning, helping students to learn reflection, and improve their learning initiative. A large number of research results show that data-driven learning is an ideal learning method in foreign language vocabulary learning [5, 6]. In addition, corpus linguistics also has a positive impact on the study of linguistics itself. The application of corpus linguistics in linguistics branches, such as phonetics, morphology, syntax and pragmatics, can carry out language research activities at more levels. For example, in terms of phonetics, we can carry out research activities on the way of foreign language pronunciation, and pronunciation and intonation of spoken language corpus. In the aspect of morphology, we can carry out researches on the composition and classification of words. In the field of sentence science, we can conduct research on sentence form and structure, discourse, and stylistic analysis. In pragmatics, research activities such as the use of language in the actual communicative context can be carried out [7]. The development of these research activities will help foreign language teachers master modern language rules and point out the direction for students to learn foreign language knowledge. In addition, the learning of corpus linguistics can help students understand the correct expression meaning and practical use of some words, and with the help of advanced computer technology, it helps students to realize the meaning of corpus linguistics words, sentence patterns, and other forms of language expression. It can be seen that the application value of corpus linguistics in foreign language teaching is relatively high [8–10].With the development and deepening of corpus research, language teaching and language research have obviously formed a unified trend [11]. Language teaching based on corpus adopts the “3I” teaching mode, which advocates that language teaching consisting of three stages: Illustration, Interaction, and Induction. Illustration refers to learners observing real language data. Interaction means that learners discuss and share findings in the corpus. Induction refers to the rules that learners develop for a language point, which can then be improved on by observing more data [12]. The “3I” teaching method believes that language knowledge exists in large-scale real texts, and language rules should be discovered and summarized through the investigation of real corpus, which is a bottom-up exploratory experience induction. According to data-driven learning, effective language learning itself is also a kind of language research, and the observation of index rows can promote learners to master the strategies of inductive learning, especially the strategies of distinguishing similarities and differences, inferring hypotheses, and verifying them [13]. Data-driven study argues that the vocabulary and grammar of binary opposition expand the language meaning units as much as possible, according to the language concept, the concept of the term is far greater than words, from the node word collocation, and classes to join, to semantic orientation and the semantic rhyme, from concrete to abstract vocabulary syntax level, and an extension to the pragmatic level. The results of cnKI retrieval were imported into CiteSpace software for data conversion and visual analysis. Keywords not directly related to this study were removed, such as “corpus,” “vocational English,” and “vocational English,” and then the rest of the high-frequency keywords were combined and classified. The research on the application of corpus methods in higher vocational English education can be roughly divided into nine topics, as shown in Figure 1: interlanguage research and English teaching, lexicology, corpus creation, corpus linguistics, pragmatics and cognitive linguistics, corpus technology, textbook research, language testing, and computational linguistics (Figure 1).Figure 1
Topics of English corpus research.Personalized virtual corpus is based on the fully mix traditional corpus technology advantage, through the cloud and big data network technology to overcome the disadvantage of traditional corpus, using the Internet platform of endless resources, or specify a set of corpus part of the generic corpus as a basis of source data corpus [8]. The construction process of this kind of corpus is simple and easy to use. The most important thing is that it can meet the various personalized needs of users. Therefore, it is widely used in language research and learning, which can not only improve the level of language teaching but also provide sufficient corpus and innovative research perspectives for subsequent language research. Corpus is constructed mainly with massive language samples, and it has the characteristics of authenticity and diversity of content. With the help of the language features of real language samples, corpus linguists can provide real and effective reference for foreign language learning and teaching. In the foreign language classroom, the introduction of corpus linguistics theory provides students with rich corpus resources and real language use environment. Students can use the help of corpus to find answers to their questions, thus improving their learning initiative and playing a positive role in improving the effect of foreign language teaching. With the help of the corpus, teachers can choose the important and difficult points of the classroom content reasonably, which is conducive to the reasonable arrangement of the teaching content and the smooth progress of the class. In view of the advantages of corpus linguistics in foreign language teaching, it is of great significance to actively explore the reasonable combination of foreign language teaching and corpus linguistics, which is conducive to the reform and development of foreign language education.


## 2. Related Work

Applied corpus teaching has been extensively studied. Paek and Kim [14] divide corpus functions into two categories: one is that corpus reflects social interaction function to some extent. The other is that corpus can improve the efficiency of language processing. Corpus as multifrequency words in our daily communication. If we can properly understand and use the corpus, it will help to improve our daily communication ability. So far, corpus teaching has highlighted its key role in foreign language teaching due to its s structure collocation, reasonable syntactic rules, and limited language environment, and it has injected new ideas into foreign language teaching. In daily social communication, it is found that corpus appears very frequently in oral communication, which has a certain influence on the composition of sentences. Gowin-Jones [15] pointed out the enlightenment of corpus structure on English teaching and proved that corpus teaching method is conducive to learners’ foreign language acquisition through exploration. The corpus conforms to certain syntactic rules and can be stored in the brain as a whole. This not only relieves the communication pressure but also improves the expression ability of the communicator, which occupies an important position in oral English. However, in the process of English writing teaching, corpus method has not been paid much attention. The author believes that corpus teaching plays an active role in the writing process: corpus teaching helps to improve the accuracy and fluency of learners’ use of corpus. Bibauw et al. [16] found that the input and output of high-frequency chunks are the key to improving learners’ fluency in foreign language writing. It can be further proved that chunk teaching method is conducive to improving the language competence of foreign language learners in China. Therefore, language learners can use chunks to improve their writing skills. Huo [11] points out that every native speaker has a lot of linguistic blocks stored in his mind, so he can use the language more accurately and fluently in daily communication. If learners master a certain number of idiomatic chunks, they can ensure more idiomatic and fluent language output, which is conducive to improving learners’ language ability. AlShuweihi et al. [17] explored the combination of task-based teaching method and chunk teaching method in teaching, and the statistical results show that this teaching mode is helpful to cultivate students’ autonomous learning ability and improve learners’ pragmatic ability to a certain extent. Adikari et al. [18] explored a new teaching model that combines mind mapping with chunk theory, and the experiment proved that this model can improve the effectiveness of students’ English reading to some extent.


## 3. Intelligent English Teaching Platform Based on Personalized Virtual Corpus

### 3.1. Data Source

The research data of this study are mainly derived from two corpora: One is the Chinese English learners corpus (CLEC) of college Cet-4 and Cet-6 (ST3 and ST4) and the other is the LOCNESS corpus of American College Students’ essays (brusR1, BRSUR2, BRSUR3, USARG). The total number of words in the two corpora is 416 476 (CLEC corpus) and 245 321 (LOCNESS corpus), respectively. In addition, this study chose the word “RATHER” as the target word in the case to explore a new model of college English vocabulary teaching. In English writing and conversation, the word “rather” is used in a variety of different parts of speech. It can not only be used as an adverb of degree to enhance the author’s mood and expression but also can be used with “would, than, but” and other words to express the author’s subjective will and preference or the difference in objective existence. We have collected the subtitles of 112 excellent English films and documentaries to build a film and television corpus with a wide range of subjects, including both classic business card and some excellent films in recent years, in order to fully reflect the characteristics of contemporary English. The main parameters of the corpus are shown in Table1. At the end of the experiment, 45 students in the experimental class were given questionnaires, 45 of which were effectively recovered. The questionnaire is divided into four dimensions, and the questions in each dimension. It completely matches the five choices. SPSS19.0 was used to analyze the data.Table 1

### 3.2. Design of Learning Environment Based on Constructivism

The instructional design based on constructivism attaches great importance to the design of learning environment, which is also an important feature that distinguishes it from the traditional teacher-centered instructional design. Tellez and Villela [19] believed that learning environment is a place where learners can use various tools and information resources and cooperate and support each other in the pursuit of learning goals and problem-solving activities. In this view, various tools and information resources used in learning are also included in the category of learning environment, which further enriched the concept of learning environment. He proposed a constructivist learning environment model, which consists of six parts, as shown in Figure 2:Figure 2
Constructivism-based learning environment model.To understand any problem, learners need to have some experience on the problem and be able to construct the corresponding mental model. However, for ordinary beginners, what they lack most is experience, which is very critical for them to solve problems. Therefore, it is very important for a constructivist learning environment to provide a series of relevant examples that learners can refer to. Related instances in constructivist learning environments can support learners’ learning in two ways: First, related instances in constructivist learning environments can help students memorize. When people encounter a problem or situation for the first time, they will naturally look for similar cases in their memory that they have solved before, compare their previous experiences and lessons with the current problem, and if the goals or conditions match, they will apply the method of solving the problem in the previous case. Therefore, relevant cases help or supplement memory by providing learners with representations of experience that they do not have.Secondly, relevant examples in constructivism learning environment can enhance learners’ cognitive flexibility. As a branch of constructivism theory, cognitive flexibility theory believes that traditional teaching often simplifies the real background of complex problems and gives students a one-sided understanding of the problem. Therefore, the theory advocates providing a variety of representations and explanations about content to show the complexity of the knowledge domain itself, the connections between concepts and concepts of a certain point of view, and the connections within the concept, and it also advocates to convey multiple points of view on many issues with multiple and related instances. Therefore, in order to emphasize students’ cognitive flexibility, relevant examples should provide a variety of perspectives and perspectives on the problem to be solved.The application of corpus-based intelligent technology in English education is mainly shown in the following aspects (as shown in Figure3). From the preclass preview, interactive exercises, teaching resources, and other aspects of learning path planning for learners. Push personalized learning resources to learners according to their preferences and needs; through adaptive learning, interactive, intelligent, and accurate teaching and learning can be realized. Intelligent lesson preparation can provide massive teaching resources. In the intelligent teaching link, the “smart classroom” of cross system and interactive teaching is realized to achieve the seamless connection between teaching and learning. In the intelligent work, the visual class work situation is generated automatically by the intelligent system. Relying on the intelligent teaching and research platform, the construction of online teaching and research community is conducive to the realization of online and offline linkage and the improvement of teachers’ professional skills (Figure 3).Figure 3
The relationship between corpus and other teaching elements.


### 3.3. Construction of Corpus-Assisted English Teaching Model

Corpus-assisted English teaching has the following steps:(1)
Under the guidance of teachers, students choose research questions according to the course content and interest. At the same time, the instructor should teach basic corpus retrieval methods to lay a good foundation for the following courses and activities.(2)
Make a complete study plan through group discussion and teachers’ suggestions. This plan will provide students with evidence to carry out their study activities and make them understand the general research process.(3)
Activity exploration: through the use of various reference books, computer networks, and other ways to collect and read literature, at the same time, questionnaire survey, interview, field investigation and research, and other means to collect data and use relevant statistical software for data analysis and analysis.Discuss and come to a conclusion. In this link, many language problems encountered by students can be solved through corpus retrieval, which effectively alleviates the problem of lack of teacher guidance after class.(4)
Listen to the guidance and suggestions of teachers and other students, find out the problems and deficiencies in the research in time, and make improvements in the follow-up research.(5)
Project report writing. Students summarize their research topic and submit it in the form of research report. This process can improve students’ English academic writing ability and enhance their sense of academic style. At this stage, the corpus plays a crucial role. A series of language problems, such as vocabulary, grammar, sentence pattern, and collocation, encountered by students in the process of writing can be solved through corpus retrieval, observation, analysis, and summary, especially ’students’ writing style awareness can be greatly improved.Traditional college English reading teaching is text-based, text-centered, and text-specific teaching activities. By adopting the intelligent teaching mode, teachers can break the limitation of textbooks, on the basis of analyzing the main idea of the text, search the massive real corpus related to the main idea of the text by searching the key words in the text, and provide extensive reading resources for students in the largest range. At the same time, teachers can design different types of teaching activities based on corpus to cultivate students’ critical thinking ability, practical ability, and intercultural communication ability.


### 3.4. Construction of Personalized Virtual Corpus

The reason why personalized virtual corpus has become the most commonly used form of corpus at present is inseparable from its own outstanding advantages. First of all, virtual corpus can use Internet resources to build a small corpus related to a certain topic to meet the personalized needs of users, especially suitable for the study of ESP. Secondly, the virtual corpus is easy to use. It takes about 3-4 seconds to build a virtual corpus. In addition, there are corresponding construction guidelines on many platforms, and users can easily build their own personalized virtual corpus according to the guidelines [20–22].First of all, a corpus platform website,http://corpus.byu.edu/wiki/, login to register. Second, click “Search” at the top left of the main page and click “Create Corpus” to enter the page of Corpus creation. Third, type in the subject word, which is the core word of the virtual corpus to be created, such as “Flight Procedure,” and then single click “Find matchingstrings,” and you will Find that the page displays everything related to that term. Next click SORT/LIMIT and then click “Relevance.” At the same time, the “MINIMUM” option can also be used to screen out the corpus with the lowest occurrence frequency of keywords in the text, so as to facilitate further editing of the corpus. Finally, click “Save List” to name and save the corpus, thus completing the construction of a small virtual corpus. At the same time, the corpus can be further edited and deleted, and users can complete different language research purposes according to different needs.Content-based recommendation algorithm mainly makes recommendations by obtaining the attribute characteristics of people or things. The advantage of this algorithm is that it can recommend items to users according to their preference characteristics, thus solving the recommendation problem of new items. Therefore, the selection of the similarity function is very important. By calculating the similarity between individuals, we can accurately find then neighbors of the nearest neighbor. The similarity between users is calculated according to the similarity function, and then, a set of nearest neighbor users (excluding target users) is obtained by sorting the similarity degree from large to small. The calculation formula of Euclidean distance similarity algorithm [3, 4] is given as follows:(1)ωij=ω1⋅Si,1−Sj,12+ω2⋅Si,2−Sj,22+⋯+ωn⋅Si,n−Sj,n2+g0.Application scenarios of intelligent English teaching evaluation mainly use intelligent diagnosis evaluation system to analyze students’ learning situation before class and activate students’ existing knowledge and experience. Analysis of class and individual classroom practice data and timely feedback are remedy. After class, we can timely detect the learning effect through online homework to review and strengthen. Thus created algorithm includes listening, speaking, reading, and writing comprehensive intelligent English teaching evaluation application scenarios, let the students before class, during class, and after class do not deviate from the teaching content of learning at all levels of education, on the basis of understanding English teaching content background cultural reinforcement accurate pronunciation, understanding the linguistic logic of teaching content, and learn to control self-assessment, and truly help students build their own knowledge system from preview to review after study (as shown in Figure3).(2)ωij=Si,n⟶⋅Sj,n⟶Si,n⟶−Sj,n⟶=sinSi,n⟶,Sj,n⟶.The similarity between the vectors of userSi (n) and user Sj (n) is expressed [12] by the cosine value of the angle between the space vectors, and the similarity between the vectors is proportional to this value.The calculation formula of Pearson similarity algorithm is given as(3)ωij=∑kSik+Sj1Sik+Sj1Si,1−Sj,12+Si,2−Sj,22+⋯+Si,n−Sj,n2.

## 4. Result Analysis

### 4.1. Statistics of Basic Parameters of the Corpus

Concordance 3.2 contains some statistical functions for the basic parameters of the corpus. Figure4 shows the statistical results of the basic attributes of the corpus of texts 1–6 in the Intensive reading textbook of College English by Using Concordance 3.2:Figure 4
Statistics of basic parameters of the corpus.These include types, tokens, type-token ratio, words/sentences, and other parameters mentioned in the introduction of common statistical parameters of corpus. Word length distribution function can be used to calculate the word length distribution of corpus. This parameter has important reference value for judging the difficulty and language style of corpus text. Figure4 shows the word length distribution of the corpus of texts 1–6 in the intensive reading textbook of College English (Figure 4).It can be seen from the figure that there are 235,364 graphic signs with word length of 4, accounting for 18. The total number of graphic signs was 39,149 graphic signs with word length accounting for the total number of graphic signs.


### 4.2. Comparison between Intelligent English Grammar Teaching and Traditional Teaching

Through the analysis of the results of the pretest, it is found that the English grammar level of the two classes is similar before the experiment. This eliminates the interference factors for the experiment, as shown in Figure5. By comparing the posttest scores of the two classes, it was found that students in the experimental class with flipped classroom teaching model had a greater improvement in English grammar (Figure 5).Figure 5
Comparison between intelligent English grammar teaching and traditional teaching.The posttest results of the control class of the experimental class compared with thet-test results of independent samples showed that the t-distribution value of the test was 2.508, and the corresponding significance SIG value was 0.014, which was less than 0.05 to reach the significance level. Therefore, there was significant difference between the results of the posttest results of the control class of the experimental class. According to the statistical results of the classification mean, the posttest score of the experimental class was 38.53, which was significantly higher than that of the control class (35.07). It can be seen from this that compared with the traditional grammar teaching mode, flipped classroom teaching mode has made great progress in students’ grammar scores.Through the analysis of the test results of the control class, it is found that the students’ grammar level has been improved under the traditional grammar teaching mode, but the effect is not obvious. Through the analysis of the test results of the experimental class, it is found that the application of flipped classroom teaching mode has greatly improved students’ English grammar level, and the overall average score of the class has increased by 4.24 points. In conclusion, the flipped classroom teaching model based on ARCS model can improve students’ grammar application.Let the error cost function of studentS1 in question K1 be(4)JS1=θ10−θ11α11−θ12α12−⋯−θ1nα1n+g11.Similarly, the error cost function of studentS1 in question K2 is(5)JS1=θ20−θ21α21−θ22α22−⋯−θ2nα2n+g20.Therefore, the average error cost function of the predicted score and the real score of theSx student is(6)JSx=θ0+∑m=1mθ0α0+θnαn+∑mmgm0.


### 4.3. Corpus-Based Analysis of English Teaching Scenarios

In this teaching mode, flipped classroom is divided into two parts: preparation stage and implementation stage. The preparation stage is mainly set for the teacher, including three main links: selecting the course before class, designing the syllabus plan, and recording the teaching video. The implementation stage of flipped classroom is mainly targeted at classroom teaching setting and goal oriented. Relevant knowledge is reviewed through the review of teaching videos, knowledge is mastered through tests and group activities, and knowledge is condensed and refined through summary.Application scenarios of intelligent English teaching evaluation mainly use intelligent diagnosis evaluation system to analyze students’ learning situation before class and activate students’ existing knowledge and experience. Analysis of class and individual classroom practice data and timely feedback are remedy; After class, we can timely detect the learning effect through online homework to review and strengthen. Thus created algorithm includes listening, speaking, reading and writing comprehensive intelligent English teaching evaluation application scenarios, let the students before class, during class, and after class do not deviate from the teaching content of learning at all levels of education, on the basis of understanding English teaching content background cultural reinforcement accurate pronunciation, understanding the linguistic logic of teaching content, and learn to control self-assessment, and truly help students build their own knowledge system from preview to review after study (as shown in Figure6.Figure 6
Corpus-based analysis of English teaching scenarios.The intelligent diagnostic evaluation system makes the diagnostic evaluation system change from the original single teacher experience evaluation, diagnosis and teaching management to data-supported teaching evaluation, diagnosis and teaching management, and changes from static intervention to dynamic and adaptive intervention, such as teachers can see the students’ filling in the blanks after “Listen, Readandsay” in part A of the textbook. Compared with the previous teachers who only listened to most people’s answers or asked questions, the intelligent diagnosis and evaluation system can immediately feedback the answers when the students answer the questions, so that the teachers can timely adjust the content of the teaching. Teach students more precisely where they are weak.The evaluation process of intelligent diagnosis includes the whole process of pre-evaluation before test, postevaluation after summary, and real-time data evaluation before, during, and after class [13].


### 4.4. Application and Analysis of Intelligent Teaching Platform

In order to test the practical effect of English wisdom classroom teaching, explore the shortcomings of this model, summarize experience, and lay an effective practical basis for the development of wisdom classroom teaching model in this school. We conducted a questionnaire survey. A total of 20 questions were set in the questionnaire, and the content of the survey also included multiple dimensions. The five-scale Likert method was adopted to design the questionnaire as follows: Strongly agree, agree, General, Disagree, and strongly Disagree. The single or multiple choice questions were mainly used, and the last question was an open question, as shown in Table2.Table 2
Questionnaire survey index.

Most students want to apply this model to other classroom activities. It can be concluded that the majority of students have a high evaluation of the model, fully showing the advantages of the model, and they also want to change the traditional model, integrate technology into the classroom, and stimulate personal interest (Figure7).Figure 7

(a)(b)(c)(d)The analysis in Figure7 shows that, in terms of learning interest, 41.08% of the students think that learning activities in smart class stimulate their interest in learning business English, 12.43% of the students hold the opposite opinion, and only 4.86% of the students think that this activity cannot arouse their interest in learning this course at all. In terms of answering questions, 69.19% of the students were able to solve the problems they encountered in the learning process through the intelligent platform, whereas only 4.32% of the students disagreed. The comprehensive analysis of various factors and data shows that most secondary vocational students can accept this teaching mode, and a few do not agree with it, which may be because there are some obstacles in the learning process such as hardware and software problems, which lead to dissatisfaction with this mode. In terms of creating a relaxed learning environment in the classroom, about 70% of the students agreed with the relaxed and happy learning environment that smart classroom can create, whereas only 4.86% of the students said they dislike this kind of learning environment very much. After the wisdom of classroom teaching mode, the effect of the most important is whether the testing platform of learning resource wisdom deepen the understanding of knowledge; the data show the learner’s point of relative balance: 14.59% of the learners do not agree with and about 60% of the learners think teachers classroom learning resources released by wisdom can further promote their understanding of knowledge. Therefore, in the future learning process, the release of teaching resources should be more in line with the practical needs of learners, and the content of resources should be more targeted.The introduction of intelligent classroom teaching mode has greatly improved the participation of secondary vocational students in business English courses. As can be seen from Figure8, nearly half of the students believe that the smart classroom platform can improve the frequency of interaction between teachers and students. It is understood that under the previous teaching mode, many secondary vocational students do not actively participate because of the class students, courage, and other reasons, resulting in less interaction with teachers, but through the wisdom platform, students can timely and effectively communicate with teachers; 41.62% of the students actively completed the learning task pushed by the teacher on the platform, 30.81% of the students generally agree with it, and only a few students do not agree. It can be seen that the smart platform effectively improves students’ participation in class and their interest in learning (Figure 8).Figure 8

## 4.1. Statistics of Basic Parameters of the Corpus

Concordance 3.2 contains some statistical functions for the basic parameters of the corpus. Figure4 shows the statistical results of the basic attributes of the corpus of texts 1–6 in the Intensive reading textbook of College English by Using Concordance 3.2:Figure 4
Statistics of basic parameters of the corpus.These include types, tokens, type-token ratio, words/sentences, and other parameters mentioned in the introduction of common statistical parameters of corpus. Word length distribution function can be used to calculate the word length distribution of corpus. This parameter has important reference value for judging the difficulty and language style of corpus text. Figure4 shows the word length distribution of the corpus of texts 1–6 in the intensive reading textbook of College English (Figure 4).It can be seen from the figure that there are 235,364 graphic signs with word length of 4, accounting for 18. The total number of graphic signs was 39,149 graphic signs with word length accounting for the total number of graphic signs.


## 4.2. Comparison between Intelligent English Grammar Teaching and Traditional Teaching

Through the analysis of the results of the pretest, it is found that the English grammar level of the two classes is similar before the experiment. This eliminates the interference factors for the experiment, as shown in Figure5. By comparing the posttest scores of the two classes, it was found that students in the experimental class with flipped classroom teaching model had a greater improvement in English grammar (Figure 5).Figure 5
Comparison between intelligent English grammar teaching and traditional teaching.The posttest results of the control class of the experimental class compared with thet-test results of independent samples showed that the t-distribution value of the test was 2.508, and the corresponding significance SIG value was 0.014, which was less than 0.05 to reach the significance level. Therefore, there was significant difference between the results of the posttest results of the control class of the experimental class. According to the statistical results of the classification mean, the posttest score of the experimental class was 38.53, which was significantly higher than that of the control class (35.07). It can be seen from this that compared with the traditional grammar teaching mode, flipped classroom teaching mode has made great progress in students’ grammar scores.Through the analysis of the test results of the control class, it is found that the students’ grammar level has been improved under the traditional grammar teaching mode, but the effect is not obvious. Through the analysis of the test results of the experimental class, it is found that the application of flipped classroom teaching mode has greatly improved students’ English grammar level, and the overall average score of the class has increased by 4.24 points. In conclusion, the flipped classroom teaching model based on ARCS model can improve students’ grammar application.Let the error cost function of studentS1 in question K1 be(4)JS1=θ10−θ11α11−θ12α12−⋯−θ1nα1n+g11.Similarly, the error cost function of studentS1 in question K2 is(5)JS1=θ20−θ21α21−θ22α22−⋯−θ2nα2n+g20.Therefore, the average error cost function of the predicted score and the real score of theSx student is(6)JSx=θ0+∑m=1mθ0α0+θnαn+∑mmgm0.


## 4.3. Corpus-Based Analysis of English Teaching Scenarios

In this teaching mode, flipped classroom is divided into two parts: preparation stage and implementation stage. The preparation stage is mainly set for the teacher, including three main links: selecting the course before class, designing the syllabus plan, and recording the teaching video. The implementation stage of flipped classroom is mainly targeted at classroom teaching setting and goal oriented. Relevant knowledge is reviewed through the review of teaching videos, knowledge is mastered through tests and group activities, and knowledge is condensed and refined through summary.Application scenarios of intelligent English teaching evaluation mainly use intelligent diagnosis evaluation system to analyze students’ learning situation before class and activate students’ existing knowledge and experience. Analysis of class and individual classroom practice data and timely feedback are remedy; After class, we can timely detect the learning effect through online homework to review and strengthen. Thus created algorithm includes listening, speaking, reading and writing comprehensive intelligent English teaching evaluation application scenarios, let the students before class, during class, and after class do not deviate from the teaching content of learning at all levels of education, on the basis of understanding English teaching content background cultural reinforcement accurate pronunciation, understanding the linguistic logic of teaching content, and learn to control self-assessment, and truly help students build their own knowledge system from preview to review after study (as shown in Figure6.Figure 6

## 5. Conclusion

In the age of intelligence, according to the core quality of English subject, artificial intelligence technology has supported every link of English education. This study established an English teaching platform based on personalized virtual intelligence. The process of applying artificial intelligence technology to English teaching effectively from the aspects of English listening, speaking, reading, and writing assisted by the platform to teaching, teacher research, and other aspects, makes English teaching more effective in cultivating students’ core competence in English subject and cultivating students’ English cultural awareness. Corpus-data-driven college English teaching mode broke the limitation of “class + textbook,” changed the traditional mode of college English teaching, has realized the student-centered task type, exploratory, autonomous learning, is to explore to adapt to the economic development of new technologies, new industries, and new engineering education system with Chinese characteristics of beneficial attempt. Through teaching practice, it is found that more attention should be paid to the following three problems in future teaching: (1) Free corpora such as COCA and BNC are monolingual corpora, which are difficult for learners, especially non-English majors; ② Students often get bored and confused by the complicated original search results. Therefore, we should pay full attention to students’ interests and give them more encouragement. (3) Using DDL mode, teachers need to carefully design teaching activities and exercises, create teaching micro text, the workload of teachers is very large, so its large-scale promotion needs to have a strong teaching team support, to carry out cooperative lesson preparation.In the future, we will carry out deeper and more extensive DDL college English teaching practice, and on the basis of empirical research, in quantitative research methods to explore the effect of the model to improve the students’ comprehensive quality, constantly summarize and interactive teaching mode guided by teachers, in order to help Chinese learners to open up a new, highly effective, the wisdom of English learning.
