## Abstract

In order to solve the practical problems existing in audiovisual teaching, this paper introduces the BOPPPS model and discusses the organizational mode of audiovisual teaching. Firstly, the inherent meaning of BOPPPS model and hybrid teaching is analyzed, and the suitability of BOPPPS model in audiovisual teaching is clarified. Then, the audiovisual teaching framework based on BOPPPS model is constructed from the perspective of practice. Application strategies are summarized from bridge-in, learning objective, preassessment, participatory learning, postassessment, and summary stages and finally explore matters for attention with examples. The process is systematic and comprehensive, which can provide guidance for teaching practice. The results found that after three days of learning with only hearing, 15 percent of students retained their memory, 40 percent of students with only seeing, and 75 percent of students with only hearing. It can break through the time and space limitation of offline classroom teaching and effectively solve the dilemma of audiovisual courses for English majors.

## Body

## 1. Introduction

Audiovisual teaching, as a key content form of college English course organization, has a solid theoretical basis of linguistics and can obviously change the disadvantages of traditional education. China attaches great importance to the reform of college English teaching. As early as 2002, the first reform project was launched, and the system has been continuously improved since then. Audiovisual teaching mode has also been popularized, which has changed the disadvantages of disjointed audiovisual teaching and single and backward teaching mode under the traditional mode and provided a boost to the training of language ability of senior talents [1]. A general survey of the existing audiovisual teaching model shows that traditional “3P” teaching is still dominant. Classroom organization follows the inherent modes of presentation (presenting new knowledge), practice (practice), and production (output). Teachers read and listen to certain materials repeatedly as long as students have difficulties. Individual differences and needs of students cannot be taken into account [2]. And the practice and output link time is short; the activity form is rigid. The enthusiasm of students to participate in class is not high, and the subjectivity cannot be guaranteed, so it is necessary to reform and optimize its methods.


## 2. Literature Review

Originating from Canada’s National Teacher Skills Workshop (ISW), the BOPPPS teaching model has been promoted to many countries and regions around the world and received wide attention from education researchers [3]. Based on the theory of constructivism and communicative approach, the model emphasizes the student-centered teaching concept and the principal role of students in the teaching process. It helps teachers disassemble classroom teaching process, organize effective teaching activities, use feedback information, and explore and eliminate the blind spots in teaching, so as to achieve the purpose of improving teaching quality and effect. From a psychological point of view, the golden span of human attention is maintained at about 15 minutes. Only by grasping this golden period can we make teaching get twice the result with half the effort. In the current college English audiovisual speaking teaching, the duration is roughly maintained at 45 to 50 minutes, and students’ attention and learning efficiency fluctuate greatly (see Figure 1), making it difficult to ensure efficient learning in the whole process [4].Figure 1
The change of learning efficiency in English class over time.According to this psychological law, the BOPPPS model divides the classroom teaching process into six teaching units. Each teaching unit follows the sequence of “start, transfer, and merge” within and between units. The six units (six elements of the model) are as follows: bridge-in, learning objectives, preassessment, participatory learning, postassessment, and summary, BOPPPS for short [5]. Introduction (B) is to attract students’ attention, stimulate students’ interest and motivation in learning, and guide them to enter the new content smoothly; learning objectives (O) are defined as classroom learning objectives and expected outcomes according to the cognitive, affective, and technical aspects of Bloom’s educational objectives; pretest (P) is used to evaluate students’ knowledge base and understanding of the content to be taught in class, which is used to guide the subsequent teaching arrangements. Participatory learning (P) is the interactive learning of curriculum content through the all-round interaction between teachers and students. Teachers use active teaching strategies to encourage students to deeply participate in class to achieve teaching objectives. It is the core link of classroom teaching. Posttest (P) is to determine students’ knowledge mastery degree related to classroom learning and teaching objectives and to test whether they reach the established goals. Summary (S) is to consolidate learning results by sorting out knowledge points or skill points in classroom teaching, summarize and reflect on the teaching process, and prepare for the next lesson [6]. The BOPPPS teaching model is also known as the Effective Teaching Model (see Figure 2). Following the closed-loop feedback process of “teaching objectives ⟶ teaching behavior ⟶ learning activities ⟶ teaching evaluation ⟶ teaching objectives,” its core has three points: clear and attainable learning objectives, the teaching process in which students participate in all aspects, and timely teaching feedback.Figure 2
Structure of BOPPPS teaching model.For a long time, college English audiovisual teaching is basically teacher-centered, while students are passive receivers. Teachers often focus on training students’ listening skills, overemphasizing language input while ignoring language output, resulting in disconnection between listening and speaking and lack of comprehensive training integrating sight, listening, and speaking [7]. The pattern of “listen to the text and check the answers” is often repeated mechanically in class. The teaching design is too simple and the audio content lacks effectiveness, which leads to the frequent occurrence of “deaf English,” “dumb English,” and “silent classroom,” which seriously affects students’ learning enthusiasm and teaching quality. From the perspective of educational psychology, the teaching effect produced by one-way indoctrination mode is also very poor. If the efficiency of audiovisual teaching and demonstration teaching can be maintained at 20%~30%, the efficiency of single teaching method may only be about 5% (see Figure 3) [1].Figure 3
Pyramid of teaching method effectiveness.In today’s information age, the deep development of “Internet +” technology has put forward higher requirements for information education. It has become an urgent task to adopt modern educational technology to reform the teaching content, teaching means, and teaching methods of college English audiovisual speaking [8]. In recent years, flipped classroom, MOOCs, SPOC, microclasses, cloud universities, and other new teaching concepts and models have been springing up (see Figure 4). It has broken the barriers of traditional education, reshaped people’s learning behavior and habits, and changed people’s understanding of education. The hybrid teaching scheme has also begun to emerge. The reform of teaching methods began to appear, and the application ideas and strategies have been improved, but it has not been extended to all links of introduction and evaluation before and after class.Figure 4
Initial attempt of mixed teaching mode.In the new era, technological innovations have enriched the content of mixed teaching, which effectively integrates the advantages of various teaching modes and integrates online self-study with offline classroom. Traditional classroom teaching was reconstructed from the aspects of teaching content, teaching methods, teaching organization, and evaluation methods, emphasizing “the mixing of learning resources, learning environment, learning methods, and learning styles” [9]. Mixed teaching mode has become an important trend of teaching development under the background of “Internet +” and also provides an important research direction for college English teaching reform. Based on the characteristics of college English audiovisual speaking teaching, this paper will discuss how to realize the deep combination of “Internet +” education in this course and carry out digital, network, and personalized teaching, so as to explore a mixed teaching mode suitable for the characteristics of this course (see Figure 5).Figure 5

## 3. Application Suitability of BOPPPS Model in Audiovisual Courses

### 3.1. Audiovisual Teaching Characteristics

As a method to start the language acquisition mechanism, audiovisual teaching is intuitive, novel, diverse, and interesting with the platform of network and multimedia technology and the guidance of mature language acquisition theory [10]. This teaching mode takes language input as the premise of language learning or acquisition, and the input is characterized by both words, texts, and sounds, integrating language knowledge and cultural information. Therefore, it changes the traditional input mode dominated by blackboard and chalk. While the input function is emphasized, the output function is also emphasized, because the output enhances the understanding of the input and promotes the absorption of the input (see Figure 6). In the output process, learners’ initiative and interactive feedback are highlighted; that is, learners are required to take the initiative to construct knowledge meaning in the real or nearly real communicative environment created by input [11]. This kind of collaborative learning can be within a group as well as across time, space, and region. Through collaborative learning, learners’ interpersonal intelligence and self-knowledge intelligence are developed. In a word, the concept of audiovisual teaching method, teaching method, classroom organization, and management mode are different from the traditional way.Figure 6
Understandability output and second language acceptance logic.In this mode, students are the subjects and active constructors of knowledge meaning, while teachers are the organizers, instructors, helpers, and promoters of meaning construction in the teaching process [12]. The research of cognitive psychology shows that the learning process is special, and language learning is no exception. The development of linguistic intelligence is inseparable from memory. The research of cognitive psychology shows that the learning process is special, and language learning is no exception. The development of linguistic intelligence is inseparable from memory. There are three types of memory: sensory memory, short-term memory, and long-term memory. Sensory memory or instantaneous memory is the starting point and foundation of memory activities. After information is entered into sensory memory, part of the information will disappear, and part of the information will be transferred to short-term memory or working memory. Only after the information entered into short-term memory is sorted, refined, and processed by the brain can it be retained for a considerable time, that is to say, it can be entered into long-term memory. Therefore, sensory memory is a key step in the memory process, and the quality of sensory memory depends on whether various senses work together (see Table 1) [13].Table 1

### 3.2. Advantages of BOPPPS Model

BOPPPS teaching mode has a solid theoretical basis and can promote the teaching reform in an all-round way. First of all, the construction and application of the new teaching model are based on behaviorism learning theory [14]. In the theoretical system of behaviorism learning, the learning process is considered to be under the influence of external stimuli; learners constantly form behavioral habits and then achieve the result of continuous reinforcement. BOPPPS classroom teaching mode effectively combines the stimulation of teachers with the cultivation of students’ autonomous behavior habits and makes full use of the results of students’ autonomous learning to strengthen the behavior expected by teachers [15]. In the application process of BOPPPS classroom teaching mode, teachers give students enough learning space and guide them to actively explore and discover new knowledge based on existing knowledge and experience, which can not only achieve better learning effect but also effectively shape students’ creative and innovative thinking (see Figure 7) [16]. Thirdly, it is based on the primary teaching principle, which divides the teaching process into five stages: problem focusing, existing knowledge activation, new knowledge demonstration, new knowledge application, and integration. Guided by this, the design of teaching activities can be optimized to better solve the problems in the teaching process and improve teaching strategies [17].Figure 7

### 3.3. Theoretical Basis of the Combination of Audiovisual Teaching and BOPPPS

In the 1960s, experimental psychologists conducted an experiment, and the result showed that the vast majority of human knowledge (94%) is acquired through visual and auditory channels, and the proportion of memory retention will be greatly improved when the two sensory organs are used together [18]. In addition, as an important link in human society, communication not only involves language itself but also paralinguistics and extralinguistics, which are commonly used by us. In communication, the pitch and sound quality of the communicator and other nonverbal behaviors including gesture, posture, body posture, hand touch, facial expression, eye contact, body distance, and other nonverbal behaviors are conducive to the expression and understanding of information. In the input and output hypothesis, the mechanism and mode of second language reception are systematically dissected. Krashen, the representative of the theory, sets the current learning state of learners as “I” and the next stage is “I+1.” It requires that the input that learners are exposed to must be higher than the original level or the stored knowledge is conducive to language learning or acquisition, and the learning effect can reach “I+1” (see Figure 8) [19].Figure 8
Krasheni+1 theory.The output hypothesis states that comprehensible inputs alone cannot make learners use language accurately and fluently, and successful learners need to be pushed to produce comprehensible outputs. Output has four functions: (1) notice and trigger function, (2) hypothesis verification function, (3) metalinguistic function, and (4) automatic function of target language expression. The output function enables learners to find the gap between their own interlanguage and the target language and promotes learners’ attention, control, and internalization of language knowledge. In terms of language acquisition, it can be seen from Figure9 that the output process involves multiple mechanisms [20]. The graphic information can be distilled as follows: (1) comprehensible input is the premise. (2) Learners’ initiative: in the process of input, the learner’s internal language monitoring mechanism should come into play. For example, learners should pay attention to the part of input that is easy to induce language transfer, because it is related to the correctness and appropriateness of interlanguage, and they should also consider the relationship between language form and language meaning; (3) interactive feedback.Figure 9

## 4. Mixed Teaching Construction of College English Audiovisual Speaking Course Based on BOPPPS Model

The BOPPPS teaching model emphasizes participatory learning, which can improve students’ abilities of listening and speaking, cooperation, innovation, and reflection. However, there are problems such as difficult unity of opinions among student group members and unbalanced participation, resulting in less learning output of students [21]. The main reason lies in the limited classroom time of audiovisual courses. Teachers need to interact more with students within a limited time and try to make every student participate in classroom activities to help them master listening and speaking skills. In order to better apply the BOPPPS teaching model in the audiovisual courses of English majors, teachers should combine the hybrid teaching model with the BOPPPS model so that students can not only carry out in-class knowledge learning but also complete teaching practice assignments on the learning platform. At the same time, targeted listening and speaking training and demonstration should be conducted according to real scenes to enhance the interaction between teachers and students (see Figure 10).Figure 10
Online mixed multiple teaching model.At the same time, teachers can add reevaluation to optimize the evaluation means, understand the changes of students in the whole teaching process by means of multiple evaluation, and constantly summarize and reflect, so as to better conduct the course teaching design, so as to enhance the teaching effect of audiovisual courses [22]. Based on the idea of mixed teaching, under the guidance of BOPPPS teaching model, the author carries on the teaching practice of English audiovisual speaking course. Specifically, the author chooses the new college English audiovisual course, tries to apply the six links of BOPPPS teaching mode to the teaching design and construction process of this unit, and carries out the mixed teaching practice of this course. The author starts from preclass, in-class, and after-class. The preclass preview stage is divided into introduction, learning objectives, and pretest. The in-class learning stage is mainly participatory learning, and the after-class consolidation stage is divided into posttest and summary. These three stages run through each other, and the combination of online and offline enables students to learn English listening and speaking knowledge step by step and stimulate their learning enthusiasm and sense of efficacy (see Figure 11).Figure 11
Online mixed multiple teaching mode based on BOPPPS model.


## 5. Mixed Teaching Stage of College English Audiovisual Speaking Course Based on BOPPPS Model

According to the content of BOPPP model, the blended teaching stage of college English audiovisual speaking course is divided into three steps. The teaching methods and expected effects of each step can be seen in Table2.Table 2

### 5.1. Stage before Class

The main teaching activities in the preclass stage are teachers’ guidance and students’ self-study and evaluation. In view of the situation of insufficient preclass learning guidance and poor effect, three elements including introduction (B), learning objective (O), and pretest (P) are integrated into the preclass stage. The first is the import design (see Figure12). Teachers design an effective import according to the teaching schedule and content arrangement to attract students’ attention and stimulate their interest in learning. Then, the key and difficult points in the teaching content are interspersed into the case explanation to improve students’ attention to the content [23]. Introduction methods can be designed in various forms, such as setting up situations related to the teaching content, finding some relevance from students’ existing experience, or raising a question to stimulate students’ interest.Figure 12
Available examples of import methods.Secondly, the teacher clearly informs the students of the specific learning objectives of this class so that they know what they need to be familiar with and master and arranges preclass learning tasks in line with the students’ ability level. One week in advance, teaching resources such as preclass learning list, content outline, micro video importing videos, knowledge points, and PPT should be uploaded to the platform. Questions and tests should be inserted into the micro video, and the bullet screen should be opened for students to express their opinions at any time. In the process of independent learning before class, when students encounter problems that are difficult to understand and solve, they use platforms or instant message groups to communicate and interact with teachers, students, and peers anytime and anywhere [24]. The BOPPPS model emphasizes testing and evaluating students’ preclass learning effect before participative learning begins. Teachers give feedback in time to guide students to gradually change from passive learning to active learning, which helps teachers to fully grasp the learning situation, timely adjust the teaching design, and arrange teaching activities more scientifically and reasonably (see Figure 13).Figure 13
BOPPPS model preparation before class.


### 5.2. In-Class Learning

The teaching activities in class mainly include live broadcast or recorded explanation, interactive communication, task exploration, and in-class quizzes. Teachers make classroom teaching design according to teaching objectives and students’ questions and test results collected before class. The teaching process mainly includes teachers initiate livestreaming through class groups, and students start livestreaming in class after checking in. The live broadcast mainly explains the key and difficult points and connects the knowledge points in series to answer students’ questions in preclass preview and assign tasks by teachers. Students write in groups to explore and discuss activities and complete the presentation of their achievements. Teachers evaluate students from individual, group, and whole from multiple angles and then arrange appropriate in-class tests to deepen students’ understanding of knowledge content and help students to complete the internalization of knowledge. Finally, the classroom summary, the teacher on the teaching and difficult points, as well as each group of difficult problems to sum up. It helps students to further consolidate knowledge and form a holistic understanding and understanding of the course content. Meanwhile, it helps students and teachers to prepare for after-class review and the next class by using the platform tools. In this stage, participatory learning (P), posttest (P), and summary (S) in the BOPPPS model are integrated, and the whole process is interspersing with teacher communication cycles, peer communication cycles, teacher practice cycles, and peer demonstration cycles, finally achieving the overall goal of digestion and absorption (see Figure14). For grammar problems, we can also explain with the help of formulas. For example, when two or more people jointly own, A+B⋯+and+C′s should be used; when two or more people separately own, A+′s+B+′s⋯+and+C+′s should be used. In some cases, three or more are involved, so one⋯another⋯theother is used as an auxiliary expression. At present, the three commonly used formulas include
(1)A+B⋯+and+C′s,(2)A+′s+B+′s⋯+and+C+′s,(3)one⋯another⋯theother.Figure 14
Circular ecology of college English classroom based on BOPPPS model.Participatory learning (P) is the core of classroom teaching activities. It is a teacher-guided interactive teaching method, including the interaction between teachers and students and the interaction between students. Teachers around the predesigned learning tasks actively create a democratic, equal, and harmonious teaching atmosphere so that students of different knowledge levels can actively participate in the whole process of classroom learning. Students complete the assigned tasks independently or in groups to internalize knowledge and explore new knowledge. Each group can be assigned a different task, or the same task topic can be discussed in depth. Teachers need to grasp the direction, pay attention to the learning dynamics of each group, and guide students to analyze and solve problems. Take the problem as an opportunity to carry out timely critical discussion, activate students’ enthusiasm and thinking (see Figure15), and guide students to conduct cooperative exploration, sorting, and summary within the group. Provide targeted and personalized guidance to all kinds of problems. When encountering common problems, focus on explaining and ask students to operate and demonstrate. I also communicated with other groups about their problems, solutions, and ideas and shared the harvest. In the whole process, teachers and students keep active and effective interaction and guide students to cooperate in exploring to complete the construction of knowledge system through communication and feedback.Figure 15
Schematic diagram of critical discussion process.


### 5.3. Consolidation after Class

In the after-class stage, students should be comprehensively evaluated and further summarized, summarized and reflected based on the overall framework content of the online mixed multiple teaching model of BOPPPS. The integrated elements are posttest (P) and summary (S). The test is divided into online tests and homework, and the test content should reflect students’ actual mastery of teaching objectives after classroom learning. The test method should be set differently according to the characteristics of the course content. For example, the concept and principle content should be set as objective questions such as selection and judgment. Ask questions and assign practical tasks for skill practice content, and test attitudes and values by means of questionnaire and discussion. According to the students’ answer situation, teachers will provide correction answers or personalized guidance through the platform and instant message group. In summary, teachers sort out the knowledge and skills learned in class to help students reflect and consolidate what they have learned and prepare for the follow-up study of the course. Teachers push the sorting and summary of classroom content to students through online platforms, requiring students to draw knowledge trees or mind maps for important content to enhance memory and understanding, and help consolidate and internalize knowledge. Finally, teachers provide students with extended learning resources, which, as an extension of classroom teaching, promote the connection of knowledge inside and outside the classroom, expand the scope of knowledge, and cultivate students’ ability to independently obtain information, independently explore, and analyze and solve practical problems. With teachers’ timely guidance, teachers and students continue to maintain good interaction (see Table3).Table 3

## 5.2. In-Class Learning

The teaching activities in class mainly include live broadcast or recorded explanation, interactive communication, task exploration, and in-class quizzes. Teachers make classroom teaching design according to teaching objectives and students’ questions and test results collected before class. The teaching process mainly includes teachers initiate livestreaming through class groups, and students start livestreaming in class after checking in. The live broadcast mainly explains the key and difficult points and connects the knowledge points in series to answer students’ questions in preclass preview and assign tasks by teachers.

Teachers evaluate students from individual, group, and whole from multiple angles and then arrange appropriate in-class tests to deepen students’ understanding of knowledge content and help students to complete the internalization of knowledge. Finally, the classroom summary, the teacher on the teaching and difficult points, as well as each group of difficult problems to sum up. It helps students to further consolidate knowledge and form a holistic understanding and understanding of the course content. Meanwhile, it helps students and teachers to prepare for after-class review and the next class by using the platform tools.

For grammar problems, we can also explain with the help of formulas. For example, when two or more people jointly own, A+B⋯+and+C′s should be used; when two or more people separately own, A+′s+B+′s⋯+and+C+′s should be used. In some cases, three or more are involved, so one⋯another⋯theother is used as an auxiliary expression. At present, the three commonly used formulas include
(1)A+B⋯+and+C′s,(2)A+′s+B+′s⋯+and+C+′s,(3)one⋯another⋯theother.Figure 14

I also communicated with other groups about their problems, solutions, and ideas and shared the harvest. In the whole process, teachers and students keep active and effective interaction and guide students to cooperate in exploring to complete the construction of knowledge system through communication and feedback.Figure 15

In the after-class stage, students should be comprehensively evaluated and further summarized, summarized and reflected based on the overall framework content of the online mixed multiple teaching model of BOPPPS. The integrated elements are posttest (P) and summary (S). The test is divided into online tests and homework, and the test content should reflect students’ actual mastery of teaching objectives after classroom learning. The test method should be set differently according to the characteristics of the course content. For example, the concept and principle content should be set as objective questions such as selection and judgment. Ask questions and assign practical tasks for skill practice content, and test attitudes and values by means of questionnaire and discussion. According to the students’ answer situation, teachers will provide correction answers or personalized guidance through the platform and instant message group. In summary, teachers sort out the knowledge and skills learned in class to help students reflect and consolidate what they have learned and prepare for the follow-up study of the course. Teachers push the sorting and summary of classroom content to students through online platforms, requiring students to draw knowledge trees or mind maps for important content to enhance memory and understanding, and help consolidate and internalize knowledge. Finally, teachers provide students with extended learning resources, which, as an extension of classroom teaching, promote the connection of knowledge inside and outside the classroom, expand the scope of knowledge, and cultivate students’ ability to independently obtain information, independently explore, and analyze and solve practical problems. With teachers’ timely guidance, teachers and students continue to maintain good interaction (see Table3).Table 3

## 6. Notes on Mixed Teaching of College English Audiovisual Speaking Course Based on BOPPPS Model

### 6.1. Complete Teaching Design Comprehensively

Although the application of BOPPPS teaching model highlights the principal role of students in the learning process and changes the deficiency of the traditional teaching mode of teacher-centered and indoctrination teaching, in terms of practical application, teachers are still required to do a more comprehensive teaching design to achieve all-round guidance of the teaching process. The application of BOPPPS teaching model makes clear the tasks of teachers and students in the learning process, but in the development of teaching activities, the cultivation of students’ divergent thinking is more obvious. Teachers may encounter many novel problems in each link of teaching activities, which will affect the advancement of teaching process. Therefore, it is necessary to strengthen the harmony of proportion of various methods and fully highlight the superiority of hybrid teaching method (see Figure16).Figure 16
Methodological framework of college English audiovisual speaking teaching.


### 6.2. Construct and Improve Teaching Logic

BOPPPS model is a comprehensive innovation of traditional teaching mode, and the logical relationship between teaching processes is more obvious. Only on the basis of ensuring the comprehensive realization of the previous teaching design can we lay a foundation for the orderly advancement of the subsequent teaching process. Therefore, in the process of teaching organization, teachers must build a perfect teaching logic system, clarify the tasks of teachers and students at each stage, and ensure that the teaching process can be effectively promoted. In the early stage of the application of the new teaching mode, some students do not have a deep understanding of the application requirements of the teaching mode and are unwilling to take the initiative to speak up, which will cause problems in different aspects of the organization of the teaching process. For teachers, it is necessary to summarize problems in all aspects in a timely manner based on the promotion characteristics of teaching activities and find out the causes of problems through in-depth communication between colleagues. The way of teaching organization should be optimized to promote the continuous optimization of the logical system of teaching, which lays a good foundation for the embodiment of the effectiveness of teaching reform (see Figure17).Figure 17

### 6.3. Optimize the Evaluation Method

College English course learning itself has obvious characteristics, and it has higher requirements for the continuity of learning activities, especially the connection and transformation between new and old knowledge, which requires students to complete knowledge assimilation more smoothly. Due to the different learning characteristics of students at the individual level, diversified evaluation methods should be constructed to achieve all-round evaluation of students, so as to better understand the advantages and disadvantages of different students in the learning process, and achieve targeted guidance for students and comprehensive cultivation of core literacy. At the same time, in the process of teaching activities, we should also actively build a process evaluation system, systematically collect the data of students in the learning process, and realize the tracking of the learning process. In this way, not only students’ learning dynamics can be timely understood but also students’ possible situations can be timely warned, thus realizing the continuous improvement of learning quality (see Table4).Table 4

## 7. Summary and Prospect

Based on the BOPPPS model, combined with the teaching environment, subject characteristics, and learning situation characteristics, the mixed teaching practice of English audiovisual speaking course is carried out to standardize the teaching process of the course and formulate scientific teaching design. By effectively combining students’ learning in and out of class and closely linking online courses with in-person classes, we can break through the time and space limitation of offline classroom teaching and effectively solve the dilemma of audiovisual courses for English majors. In the teaching of audiovisual courses, there are problems such as the failure to complete teaching tasks according to regulations and the wide range of learning resources and poor focus though. Through the implementation of effective classroom introduction, clear teaching and learning objectives, transformation of teachers and students’ roles, active participation in interaction, after-class summary, and reflection and diversified evaluation, it is helpful to concentrate the classroom focus, enrich the classroom activities, optimize the classroom environment, constantly improve the hybrid teaching mode, enhance students’ language application ability, innovative thinking ability and comprehensive literacy ability, reform the teaching mode of audiovisual speaking courses, and improve the teaching effectiveness of audiovisual speaking courses for English majors.
