Abstract
In order to solve the problems of restricted classroom and lack of repeated training in good curriculum, the design and development of a school life adaptation curriculum based on VR is proposed. This study identified six life adaptation themes for design and development (recognizing facial expressions, crossing the road, how to get lost, shopping, taking public transport, and job interview) and set the objectives, design principles, specific content, teaching evaluation, and other aspects of virtual reality life adaptation course. Combined with the characteristics of virtual reality, the implementation suggestions and matters needing attention are put forward. The results showed that, in the recognition of human facial expressions, 51 experts thought it was appropriate, 3 experts thought it needed to be modified, and no expert thought it was inappropriate. On the topic of crossing the road, 46 experts thought it was appropriate, eight thought it needed to be modified, and no expert thought it was inappropriate. On the theme of taking public transportation, 48 experts thought it was appropriate, 6 experts thought it needed to be modified, and no expert thought it was inappropriate. For the three major topics of how to get lost, shopping, and job interview, 2-3 experts put forward different opinions and think that the topic is not appropriate mainly because the grade arrangement is not appropriate. Conclusion. The VR-based curriculum for school life adaptation has been reviewed by experts and revised by researchers. It is scientific, interesting, and operable, solves the teaching problems of life adaptation teachers, and provides a safe, reliable, and effective practice channel for students.
1. Introduction
Virtual reality technology is one of the core contents of educational technology. The fundamental difference between virtual reality technology and other teaching methods is that virtual reality technology breaks the traditional teaching mode of one-way knowledge teaching. Students can give full play to their initiative and enthusiasm and enlighten 10 students on the fluency, flexibility, and delicacy of thinking. It provides abundant resources and convenient space for cultivating students' divergent thinking. It combines students' learning, practice, and self-test to form a vivid, lively, and active teaching method, which is beyond the reach of any traditional teaching method and method and has irreplaceable functions and effects [1]. Specifically speaking, the first is to have the special means of individualized teaching centered on students. The computer can give the learning content, instructions and questions, and other teaching information and can analyze and evaluate the learning effect according to the different solutions of students so that each student can be in a conducive to their own learning environment, with appropriate speed and multiple ideas and ways to answer questions. Second, the teaching form of virtual reality can make students choose the learning content suitable for their own difficulty and ease by observation and association according to their actual situation through a variety of sensory stimulation, so as to achieve the effect of teaching students in accordance with their aptitude. This way of learning provides students with a wider range of learning space and choice space and enhances their learning confidence. Third, virtual reality technology has interactive or man-machine dialogue characteristics. Virtual reality technology organically integrates teaching and practice so that students and computers are always in a series of alternating questioning and answering processes. In this kind of man-machine timely feedback dialogue process, students can be one or more, teaching mode can be diversified, teaching methods can be arbitrary, teaching speed can be multicontrolled, students can ask a question, a question to practice, and the computer provides a problem to solve, a changeable training function. In the process of training, students come into contact with many situations, find many problems, and propose many schemes, which broaden their thinking [2].
Virtual reality technology can also organically combine text, graphics, images, sounds, and animations and present them in front of students from all angles. This KIND of problem teaching method, heuristic teaching method, discussion teaching method, situational teaching method, suggestion teaching method, and discovery teaching method constantly stimulate the students' senses so that the students are in a state of excitement alternately through the brain regions. Thinking is fully active, arouses students' interest in learning, enriches students' imagination, and expands their thinking space. In the process of continuous increase and accumulation, creative inspiration and creative passion have been produced, and the train of thoughts has been broadened. Thinking produces flexibility, clarity, and fluency, thus cultivating students' divergent thinking and laying a good foundation for the cultivation of innovative thinking. In the discovery teaching practice, virtual reality can allow students to enter the environment where problems exist, construct virtual situations in a targeted and enlightening way, and guide students to explore. It uses a network structure form close to the characteristics of human cognition, and each node contains knowledge points of different media information. The logical link between each knowledge point constitutes the knowledge structure of the teaching content and provides a discovery learning thinking track [3]. Virtual reality teaching can not only provide good human-computer interaction but also allow students to make mistake so that students can understand the causes and consequences of mistakes and find the solution to the problem. Then, use advanced thinking skills such as analysis, comparison, induction, and reasoning to demonstrate the hypothesis, so as to approach or grasp the truth. Students develop discovery learning styles and strategies and develop high-level thinking skills. Virtual reality technology can construct the best classroom teaching environment and can provide and show a variety of realistic learning situations. Abstract learning is integrated with reality, so as to induce students' immediate thinking and stimulate students' associative thinking. Multimedia courseware has unique advantages in this regard, such as the use of computer simulation of university physics experiments in the electronic cloud. The rules of the movement of the electrons outside the nucleus are different from those of ordinary objects. They cannot be seen with the eyes and observed or measured with instruments, and there is no definite orbit for the movement of the electrons outside the nucleus. The operation speed is extremely fast, and the position of the electrons at a certain time cannot be seen, determined, and calculated. Only statistical methods can be used to describe the probability of the appearance of the exonuclear electron in a certain region of space outside the nucleus. Therefore, the content is very abstract and difficult for teachers and students to teach as shown in Figure 1.

2. Literature Review
Rohani et al. proposed that, in the development and application of virtual reality technology, more attention should be paid to the application in the field of education, which is the cradle of creating talents. If virtual reality technology can be applied to build corresponding scenarios, it will also greatly promote the development of VR technology in the future [4]. Segura et al. proposed to build a physical laboratory by applying virtual reality technology to make up for the limited operating environment in educational classrooms [5]. This research proposal has also received a great response in Malaysia. Through the construction of interactive virtual reality scenes, students' understanding of speed in physics teaching is more specific. Although the UK's research on the application and development of virtual reality technology started later than that of the United States, it paid more attention to the sensory construction of interactive scenes in its research. On the basis of simple visual experience, it also introduced vision, touch, and even smell. When people experience virtual reality interactive scenes, they have a sense of environmental substitution. Puggioni et al. proposed that the development of virtual reality technology should be conducted from the perspective of the combination of software and hardware. What software development creates is only a visual scene, and the combination of hardware and software can mobilize different sensory stimuli to form a more specific scene [6]. This research proposal has a great inspiration for the research of virtual reality technology in China. At the early stage of its development, China's virtual reality technology fully drew on the existing research results of foreign countries. Rafique and Cheung built the human science museum through the application of virtual reality technology, so as to carry out more specific reform of medical teaching [7]. The application of virtual reality technology in different fields will also determine the development focus. The application research of virtual reality technology in China has now entered the stage of visual sensory optimization, and future development will focus on the mobilization and development of multiple sensory worlds. Kami ń Ska's et al. experimental research on the direct learning ability and strategies of 4–6-year-old children shows that children have sprouted the direct learning ability under language conditions, but the age development effect is not obvious, and many strategies coexist in children's direct reasoning [8]. For example, children's knowledge of logarithms cannot be obtained through direct perception like their knowledge of size and color, but through an abstract process. Children's acquisition of mathematical knowledge is not through direct perception, but through the coordination of a series of actions. Konrad et al. tested the spatial cognition and learning ability of 4–7-year-old children and concluded that the rapid improvement period of cognitive performance of children's learning ability occurred in the 5 months (initial enrollment) from the age of 7 to 7 years [9].
Gong et al. carried out an experiment on the reasoning ability of children aged 5-6 years. The experiment proved that children at this age have the ability to initially understand the transitivity in quantity, which is also a good period to understand the transitivity. Children's cognitive structure has transitivity, and they also have learning ability [10]. Adwernat et al. combined with his own research and published a paper “the ultimate display” on virtual reality technology, proposing that the computer screen the authors use can actually act as a window to view the virtual reality world, and it is this idea that has inspired people's research boom on virtual reality technology [11]. After several years of efforts, Serrano Vergel et al. finally developed the ultimate display and named it the sword of Damocles. The display contains two CRT displays, through which more images can be displayed. At the same time, the device also includes mechanical links and ultrasonic detectors so that users can complete control through handheld terminals, thus realizing interaction with the virtual reality world [12].
Combining with the practical problems encountered by front-line teachers in special education in life adaptation teaching, a virtual reality life adaptation curriculum intervention system suitable for students in a school in China is independently developed and designed in this essay. Through long-term teaching and training, it verifies to what extent special children in a school can benefit from virtual reality intervention. The developed virtual reality intervention system will be applied to the learning of students in a school through the long-term teaching of life adaptation teachers, and the best intervention mode of VR will be explored in combination with the obstacle level of students. This will help cultivate the independent living ability of students in a school and help them better adapt to society.
3. Research Methods
The research methods are explained in the following sections.
3.1. Virtual Reality Life Adaptation Course Goal Setting
According to the curriculum standard for life adaptation in compulsory education of a school (2016 Edition), the overall goal of a life adaptation curriculum is to help students understand basic life knowledge, master necessary adaptive skills, develop good behavior habits, and form basic life adaptation ability and good morality [13–16]. Under the principle of abiding by the overall goal, in combination with the suggestions and guidance of life adaptation teachers, specific objectives of VR-based life adaptation theme teaching are proposed, as shown in Table 1.

3.2. VR Life Adaptation Course Theme Classification Design
A total of six life adaptation teaching topics were selected for the following reasons. First, the interview with life adaptation teachers found that these six life adaptation teaching topics could not provide students with practice opportunities in the actual teaching process, resulting in poor classroom effect, and belong to the top ten life adaptation teaching problems in the teaching of a school. Second, these six life adaptation teaching topics cover the low, middle, and high stages of a school, which are closely related to the daily life of students, and are of great significance to the development of students at each stage. Third, overseas VR practice teaching has given us sufficient confidence [13]. The learning of life skills is a systematic learning, and each subject can neither be learned overnight nor can be learned in one grade [17–19]. Therefore, in actual teaching, grade adjustment should be made according to individual development level, or teaching progress should be adjusted according to students' acceptance.
3.2.1. Recognizing Facial Expressions (Grade 2 and Grade 3)
Recognition of human facial expressions is the learning content of the lower grades in a school, and recognition of human emotions is the basis and premise for students to engage in social communication with others [20, 21]. However, most of the students in a school have difficulties in learning to recognize human facial expressions, especially autistic students, who experience emotions such as happiness, grief, and fear in VR. Students gradually learn to express their emotions appropriately on appropriate occasions [14]. After students recognize the expressions of anger and fear in the first part, they enter into the practice session. After participating in the last six parts, students choose the corresponding expressions (the face is covered by the Mosaic effect and the correct choice will be shown).
3.2.2. Crossing the Road (Grade 3)
Crossing the road safely is the learning content of students in low, middle, and grade levels in a school. When training students in VR to cross the road, students' obstacle degree should be taken into account, and teaching should be conducted according to the obstacle degree and actual needs of students. The arrangement of grades can be adjusted appropriately [22–25].
(1) Stage 1 (no traffic lights and no zebra crossings): at the intersection without traffic lights and zebra crossings (there are only two buildings in the southeast and southwest directions of the intersection, which can be supermarkets, hospitals, shopping malls, exhibition halls, libraries, bookstores, restaurants, convenience stores, etc.), there is only a small car coming to the left front of the subject, and the speed is very slow (the car can be seen within the subject's vision range). It was a long distance away from the subjects and the vehicle speed was very low. It was observed whether the subjects waited for the vehicles to pass before crossing the road or straight across the road, recorded the reaction time of the subjects when crossing the road, and whether the subjects flinched when crossing the road [15], as shown in Table 2.
Table 2.

| Number of vehicles | Each driving direction has 1 vehicle and a total of 4 quantities |
| The speed of the car | 10 km/h |
| Number of passengers | One person on the opposite side and only one person on the subject's side |
| Distractors | The car |
| Sound | Car horns |
| Other interference | None |
| The weather conditions | A sunny day with moderate temperature |
(2) Stage 2 (no traffic light and zebra crossing intersection): at the intersection with no traffic light and zebra crossing (there are 6 buildings in all directions of the intersection, which are relatively few, such as supermarkets, hospitals, shopping malls, exhibition halls, libraries, bookstores, restaurants, and convenience stores,), and on each street, there are one or two cars coming and going, most of which are very slow, but there is a slightly faster one, and there are a few pedestrians (2-3 people). We observe whether the subjects wait for the vehicles to pass before crossing the road safely on the zebra crossing [26–29]. The reaction times of the participants were recorded, as well as whether the participants flinched when crossing the road, as shown in Table 3.

(3) Stage 3 (intersection with traffic light and zebra crossing): at the intersection with traffic lights and zebra crossing (there are all kinds of tall buildings in each direction of the intersection, which can be supermarkets, hospitals, shopping malls, exhibition halls, libraries, bookstores, restaurants, and convenience stores,), there are also many cars, buses, electric cars, and tricycles, (in different colors, shapes, and sizes) on the four-way streets. The speed is urgent and slow, and there are many pedestrians [30–32]. Observe whether the subjects wait for the green light to turn on and then pass the zebra crossing safely after the traffic passes [16]. The reaction times of the participants were recorded; whether the participants flinched when crossing the road was also recorded, as shown in Table 4.

(4) Phase four (two consecutive intersections): two consecutive intersections were 50 m apart. The first intersection was traffic light without zebra crossing (there are all kinds of tall buildings in all directions of the intersection, which are all over the dense, and can be supermarkets, hospitals, shopping malls, exhibition halls, libraries, bookstores, restaurants, convenience stores, etc.). There are two or three cars, buses, electric cars, etc. (of different colors, shapes, and sizes) in a four-way street, and the speed is relatively slow [33, 34]. There were 5-6 pedestrians, and the participants were observed whether they waited for the green light to turn on and the traffic to pass before crossing the road safely. The reaction times of the participants were recorded; whether the participants flinched when crossing the road was also recorded.
When the subject passes the first intersection safely, he is guided to the next intersection safely through the voice prompt. At the second intersection, there are traffic lights and zebra crossings (there are all kinds of tall buildings in all directions of the intersection, which are very dense and can be supermarkets, hospitals, shopping malls, exhibition halls, libraries, bookstores, restaurants, convenience stores, etc.). There are many cars, buses, electric cars, etc. (in different colors, shapes, and sizes) on the four-way street. The speed is urgent and slow, and there are many pedestrians. We observe whether the subjects wait for the vehicles to pass and whether they wait for the green light to turn on before safely crossing the zebra crossing road [17]. The reaction times of the participants were recorded; whether the participants flinched when crossing the road was also recorded, as shown in Table 5.

3.2.3. What to Do If You Get Lost (Mayday 4th Grade)?
According to Curriculum Standards (2016 edition), life adaptation courses in middle grade are based on families, schools, and communities, focusing on cultivating students' ability to do simple housework, forming self-protection awareness, and guiding students to develop independently. The students in the middle grade of compulsory education in a school have the most basic self-care ability, and the demand for social communication is gradually increasing, and the opportunities for outdoor activities are increasing [35–38]. Through interviews with life-adapted teachers and personal participation in classroom practice, it is found that, in the teaching process of this stage, there are the biggest difficulties in the actual teaching process of how to do when lost, shopping in supermarkets, and taking buses [18]. The teaching problems in the middle grade should also be taught in VR according to the degree of obstacles and actual needs of students, and the arrangement of grades can be adjusted appropriately.
3.2.4. Shopping (Grade 4)
Shopping in the supermarket is closely related to students' life. Students in a certain school lack the opportunity to practice and exercise and do not know the process of shopping and matters needing attention.
Before going shopping, users first list what they need to buy and enter the virtual reality with a purpose.
When they come to the supermarket to prepare for shopping, the VR situation initially appears at the entrance of the supermarket. Users participate in the VR situation and enter the supermarket by following the guidance of the road signs. They go to the shelves and choose one by one according to the shopping list they have made.
The user follows the guide to the target shelf, finds the desired item, and continues to find the remaining items (or find them by themselves) in accordance with this method.
After shopping, after all the desired items have been selected, the user goes to the supermarket exit to line up the checkout. There are four checkout Windows, and at three, there are many people in line. The number of people in the queue at 1 window is small, and the user needs to queue up to check out (if he does not queue up, he will get automatic feedback from the system, such as you can't jump the queue! The system's voice instructs users to queue in order. When the user pays, the cashier asks the user:
Cashier: hello, your total charge is 50 yuan. Would you like to pay in cash or online?
User: pay online (show the payment code to the cashier). Or if the user's ability permits, pay in cash and get the change.
Cashier: thank you. You have paid. Please bring everything you bought.
User: thank you.
End of shopping learning in VR context.
3.2.5. Taking the Bus (Grade 5)
Taking the bus is what middle-grade students in a school learn. The main design ideas are as follows: for medium-sized buses, the appearance and size of buses are the same in the four stages of taking buses, and each stage is only distinguished by color. There are 30 seats in the bus, and the seats in the car, the color of the car, and the passengers should be distinguished. The bus driver's seat, steering wheel, windshield, and other stages are different.
(1) Stage 1 (a quiet, empty bus with no one waiting in line): the user waits for the bus at the bus station alone. When the bus arrives, the door opens, and the bus is empty. After swiping the card, the user enters the bus, and all the seats in the front, middle, and back rows are empty.
(2) Stage 2 (a bus with queues, a bit of noise, and a few passengers): when the user arrives at the bus station, there are 5 people waiting in line for the bus. According to the voice prompt in the VR situation and the association with the classroom teaching, the user voluntarily waits in line for the bus at the bus station (if they are not in line, they will get automatic feedback from the system, such as you can't cut in line! Then instruct them to react accordingly in order). When the car arrives, the door opens. With five passengers on board, users line up to swipe their cards to get on the bus. There were 11 passengers in the carriage, which was relatively small. There were still empty seats in the front, middle, and back rows of the bus, and some seats were filled with bags and other items. The user chooses the seat according to his own preference (if the user does not take the initiative to find a seat to sit down, a voice prompt will appear: on a crowded bus, the user can ask if he can sit in the seat with the bag). If the user chooses the seat without the bag, he can sit down directly. If you choose a seat next to a passenger with a bag, you need to get permission from the passenger first.
(3) Stage 3 (buses with queues, noisy compartments, and lots of passengers): when the user arrives at the bus stop, there are already 10 people waiting in line for the bus. According to the voice prompts in the VR situation and the association of classroom teaching, users voluntarily queue up at the bus station to wait for the bus (if they are not in the queue, they will get automatic feedback from the system, such as you cannot cut in line! Then instruct them to react accordingly in order). When the car arrives, the door opens. With 10 passengers on board, users lined up to swipe their cards to get on the bus. There were 21 passengers in the carriage, which was relatively large. There are only empty seats in the middle row and the back row of the bus, but these seats are basically filled with bags and other items. Users can choose the seat according to their own preferences (if the user does not take the initiative to find a seat, the voice prompts: let him ask if he can sit in the seat with the bag on the crowded bus). If you choose a seat next to a passenger with a bag, you need to get the consent of the passenger first, as shown in Table 6.
Table 6.
Project index reference at each stage of the bus ride.
| The number of line | The car environment | The number of people in the car | Are there any seats available? | Do you need to ask? | |
|---|---|---|---|---|---|
| Stage 1 | 1 person | Quiet | 0 | Yes, it is completely empty | No |
| Stage 2 | 6 people | A bit noisy | 5 people | Yes, more seats | According to the choice of subjects |
| Stage 3 | I1 people | More noisy | 10 people | Yes, there are fewer vacancies | Yes |
| Stage 4 | 16 people | Very noisy | 25 people | There is no vacancy | According to the situation on the bus |
3.2.6. Interview (Secondary School)
According to the Curriculum Standards (2016 edition), the curriculum of life adaptation in senior grades penetrates the understanding of society, family, and the world and focuses on developing the ability of self-protection and social adaptation, cultivating a positive and optimistic attitude towards life, so that students can live a safe and healthy life. Through interviews with teachers adapting to life, it is found that the core teaching theme of the senior stage is centered on work. The main contents include understanding common professionals (doctors and police), and students may be engaged in future career (packers, cleaners, catering, and waiters), cultivating students' consciousness of labor and labor quality (to insist, be patient, to be punctual, obey the arrangement, working with people, understanding the labor remuneration, and dry), and leading the students to participate in the internship practice (asylum to the factory to study Packers, to do cleaning work in the hotel, to the supermarket as a supermarket tally clerk, to the restaurant as a waiter, learn nail art, and learn beading). According to the life adaptation teachers, some graduates with better abilities from a certain school have been assessed by the employing unit after graduation, and indeed some students are engaged in these jobs. The graduates of a school are mostly engaged in simple repetitive work, which does not require deep knowledge, so they basically do not need to go through the tedious interview process. However, to establish a connection between workers and employers and finally determine the employment of workers, they still need to communicate with employers to leave a good impression on employers. Informal interviews between workers and employers are particularly necessary. In order to help life adaptation teachers' professional teaching in senior grades and to make the job interview of graduates of a school more smooth, VR job search training is designed to exercise the interview skills of senior students. Considering that some schools do not offer vocational education courses, the content of this stage can be arranged in the senior stage, and for schools with vocational education courses, it can also be arranged in the vocational education stage.
Before entering the VR job training system, users fill in relevant personal information through an online application, such as education experience, internship experience, and special skills, and then enter positive communication with the interviewer to train the whole interview process.
In VR, the user answers different questions raised by the interviewer, which are mainly aimed at correcting errors. If the user has inappropriate replies or fails to answer any questions, he/she can master some interview skills through repeated practice and gradually improve his/her interview level.
In the VR job training system, the interviewer finished asking questions and entered the fourth link one by one.
3.3. Learning Evaluation of VR Life Adaptation Course
The purpose of VR-based life adaptation course is to cultivate students' basic life skills and improve their ability to live independently. Due to the intelligence defects of students in a school, their acquisition of knowledge or skills often goes through a long process, requiring many exercises and practices. Therefore, life adaptation teachers need to establish “one person, one case” in the process of practical teaching. Before practicing in VR, students should be tested first to ensure that students have no adverse reactions in VR and are initially familiar with the VR environment. In practice, students' learning process in VR should be recorded and evaluated (formative evaluation). Refer to Tables 7–12 for evaluation.

3.4. Network Latency
In order to overcome the influence of the dynamic change of network on data transmission, network QoS monitoring technology is introduced, and real-time monitoring is used to lay a good foundation for intelligent transmission control. We add a timestamp to the protocol layer to monitor the network delay. We add two fields to each packet to record the last received timestamp (LRT) and the current sent timestamp (CST). After receiving the packet, the receiver calculates the local packet sending delay based on the LRT and SCT of the packet. At the same time, the processing delay of the packet in the network can be obtained by subtracting the processing delay of the peer end based on the saved last packet sending timestamp (LST) and the received packet time at the receiving end.
When end B sends A reply to End A, (1) and (2)areas follows:
| (1) |
| (2) |
When end A receives a packet from end B, its local formula is as follows:
| (3) |
Moreover, its current time is shown as follows:
| (4) |
In this case, the bidirectional delay of packet sending can be calculated as follows:
| (5) |
4. Results' Analysis
4.1. Topic Selection
The data obtained from the survey were input into SPSS and analyzed. In the choice of the theme of the VR life adaptation course, 54 experts agreed that the theme of the VR life adaptation course was suitable for the learning of students in a certain school. When it comes to recognizing facial expressions, 51 experts said they were appropriate, three said they needed to be modified, and none said they were inappropriate. On the theme of road crossing, 46 experts think it is appropriate, 8 experts think it needs to be modified, and no expert thinks it is inappropriate [19]. On the theme of taking public transportation, 48 experts thought it was appropriate, 6 experts thought it needed to be modified, and no expert thought it was inappropriate. For the three major topics of how to do lost, shopping, and job interview, 2-3 experts put forward different opinions and think that the topic is not appropriate mainly because of the grade arrangement is not appropriate. Experts suggest that the topic of what to do when lost should be taught at every grade level. Shopping is a topic that should be studied in the fifth or sixth grade. Job interviews should be studied in vocational education. See Figure 2 for details as follows:
Figure 2.
Experts' evaluation of the appropriateness of topic selection.
4.2. Target Setting
The data obtained from the survey were input into SPSS and analyzed. On the goal setting of the VR life adaptation course, the opinions of experts are also relatively consistent, and most of them think that the goal setting of the VR life adaptation course is suitable for students in a certain school. However, some experts put forward suggestions for modification, believing that the setting of some curriculum objectives is not specific enough, and it is difficult to implement in the actual implementation [20]. As for the modification opinions put forward by experts, the reasonable part is absorbed, and the goal setting of some life adaptation courses is modified to complete this part. The expert opinions are detailed in Figure 3 as follows.
Figure 3.
Experts' evaluation of the appropriateness of goal setting.
4.3. Evaluation System
On the evaluation system of the VR life adaptation course, the opinions of experts are also relatively consistent, and they believe that the evaluation system of the VR life adaptation course is suitable for the learning evaluation of students in a certain school. In the five major topics of recognizing facial expressions, crossing the road, how to get lost, shopping, and taking public transport, experts did not put forward inappropriate opinions. Only on the topic of a job interview, one expert puts forward inappropriate modification opinions. The evaluation system of the virtual reality life adaptation course was modified according to the modification opinions put forward by experts. For details, see Figure 4.

Experts' evaluation of the appropriateness of the evaluation system.
5. Conclusion
The curriculum design of a school life adaptation based on VR has been reviewed by special education experts, curriculum theory experts, and virtual reality technology experts and revised by researchers. It is scientific, interesting, and operable, solves the teaching problems of life adaptation teachers, and provides a safe, reliable, and effective practice channel for students.
For future research, it can be further improved when time permits. First of all, the selection of interview objects should be different, that is, taking into account the life adaptation teachers in different regions, levels, and stages, and ensuring the comprehensive content of the interview. Secondly, the authors should consider the needs of teachers as comprehensively as possible when the authors design and develop the problems of life adaptation teaching in various stages of cultivating wisdom schools. The teaching topics which are difficult to adapt to life mentioned by teachers are analyzed scientifically to see whether these topics are suitable for the development of auxiliary teaching in the form of VR. Further research will be carried out on topics that are suitable for the development of ADT in the form of VR. Finally, at present, only the teaching topic of crossing the road has been developed. It is necessary to accelerate the development of other VR-based life adaptation courses and put them into use to help teachers adapt to living.
