Introduction
In recent years, the concept of metaverse has gained significant attention as a result of advancements in virtual reality technology (Casey, Baggili, and Yarramreddy 2019).Metaverse, as discussed in studies by Chiou et al. (2021) and Park and Kim (2022) (Chiou et al. 2021;Park and Kim 2022), is seen as a promising frontier technology that can drive innovation and development in human society.Essentially, it is an interactive and immersive virtual space that is powered by virtual reality technology.With the advent of 5 G and 6 G networks (Porambage et al. 2021;Zhang et al. 2020), it is expected that the way educational products interact with users will undergo significant changes.The benefits of virtual reality technology, such as enhanced user interactivity and immersive experiences, have been evident in areas such as game design and digital display design.As the metaverse evolves, new interactive modes will be applied to improve the design of educational products and the construction of teaching environments (Yang et al. 2022).As technology continues to advance, artificial intelligence will play a larger role in education.Virtual reality technology will become increasingly intelligent, allowing for the execution of pre-coded interactive links that enhance the learning experience for students (Alallawi et al. 2022).
Preschool education, also known as pre-kindergarten or early childhood education, is an essential foundation for a child's overall development.It is a form of education that focuses on the physical, cognitive, emotional, and social development of children aged between three to five years old.Preschool education provides an environment where young children can learn, play, and explore their surroundings, setting them up for success in future academic and social settings (Aksenov et al. 2020;Al-Dojayli and Czekanski 2017).The primary objective of preschool education is to prepare young children for the transition to elementary school.Preschools provide children with the skills and knowledge necessary to develop social skills and cognitive abilities that will help them succeed in school.These skills include reading readiness, math readiness, and language development.
Moreover, preschools provide children with an opportunity to learn social skills such as sharing, taking turns, and cooperating with others.Preschool education is crucial in providing a strong foundation for a child's academic and social success.Children who attend preschool are more likely to perform better academically in elementary school, develop better social skills, and are less likely to have behavioral problems.Moreover, preschool education is a stepping stone toward a successful future.Children who have a strong foundation in preschool education are more likely to succeed in higher education, obtain higher-paying jobs, and have a better quality of life (Hildebrand and Ledbetter 2001;Park et al. 2020).
In the realm of education, utilizing Metaverse and virtual reality technology to develop engaging and interactive content can greatly enhance teaching resources and accelerate the pace of teaching reform (Demetriou, Spanoudis, and Mouyi 2011).This will bring about significant changes in teaching scenarios, such as moving from one-to-many to one-to-one teaching, shifting from standardized to personalized teaching methods, and transitioning from multimedia to convergence media.For teachers, their teaching activities will no longer be constrained by time and location, while for students, there will be a wider range of learning options and feedback available (Chiou et al. 2021).
Preschool education can benefit greatly from the integration of machine learning and metaverse technologies.These advanced technologies have the potential to provide personalized and immersive learning experiences for young children.Machine learning can be used in preschool education to create customized learning plans for individual children (Korkmaz and Correia 2019).Machine learning algorithms shown in Figure 1, can analyze a child's strengths and weaknesses, and then tailor the curriculum to address their specific needs.For example, if a child is struggling with reading, the machine learning algorithm can recommend specific reading activities or games to help them improve their skills.
Metaverse technologies shown in Figure 2, can provide an immersive learning environment for preschool children (Park and Kim 2022).
A metaverse is a virtual world where users can interact with each other and with digital objects in real-time.In a metaverse, young children can explore virtual environments, engage in interactive activities, and collaborate with their peers.This can help to enhance their creativity, problem-solving skills, and socialization abilities.Moreover, metaverse technologies can help preschool children to learn in a safe and controlled environment.Educators can create virtual scenarios to teach children about different situations, such as crossing the road safely or how to behave in social settings.Children can learn through trial and error, making mistakes in the virtual world without any realworld consequences.The integration of machine learning and metaverse technologies can revolutionize preschool education.These technologies can provide personalized and immersive learning experiences that enhance a child's cognitive, social, and emotional development.As such, it is essential to continue exploring the potential of these technologies in preschool education, while ensuring that their use remains safe and beneficial for young children.
The motivation behind addressing cybersecurity concerns in the context of the metaverse and preschool education arises from the increasing reliance on advanced technologies and the growing adoption of immersive digital experiences.As the metaverse gains widespread acceptance and becomes an integral part of various aspects of our lives, including education, it is crucial to ensure the safety and security of young learners within this digital environment.
Preschool education plays a vital role in shaping a child's early development, and leveraging machine learning and metaverse technologies has the potential to enhance their learning experiences significantly.However, it is equally important to prioritize cybersecurity measures to protect the privacy and well-being of children in this evolving digital landscape.
By delving into the secure construction of preschool education within the metaverse, we aim to address potential cybersecurity risks and establish a safe and enriching environment for young learners.This involves implementing robust security protocols, leveraging machine learning algorithms for personalized and adaptive learning experiences, and utilizing the immersive capabilities of the metaverse to foster engaging educational activities.
Through a comprehensive exploration of these technical aspects, we aim to highlight the significance of cybersecurity in the metaverse and emphasize the importance of secure construction when integrating machine learning and metaverse technologies into preschool education.Ultimately, our goal is to provide insights and guidance on how to navigate the intersection of these innovations, ensuring that young learners can benefit from the metaverse in a safe and protected manner.

Literature Review
Theoretical research related to the metaverse is an evolving field that has been mainly focused on virtual reality and immersive experiences.Virtual reality technology has been around since the early days of computer technology in the 1940s, but it was mainly limited to digital screens and gaming until the emergence of Oculus in 2018.As a result, the scope of research on virtual reality has expanded, and many theoretical frameworks are no longer applicable (Han et al. 2010).
Although the "Leap Motion VR Best Practices Guidelines" released in 2015 by Leap Motion provide some design guidelines for virtual reality space, they do not offer a systematic research methodology.However, recent psychological research has brought new insights into virtual reality and immersive experiences.For instance, Mihaly Csikszentmihalyi's flow theory provides a theoretical basis for immersive virtual reality scenario design, while Alan Karr's "meta-motivational state" and "reversal theory" offer a systematic review of immersive activities and experiences.James Moore's systematic analysis of the ethical subjects of computer hardware and software provides a prospective theoretical review of technology ethics, but it lacks a comprehensive analysis of human psychological factors (Moor 2001).Similarly, Chen Wei's (Chang, Yeh, and Li 2020) "On the Influence of Virtual Reality Technology on Epistemology" presents three major effects of virtual reality technology on cognition, which expands the cognitive object in terms of breadth and depth, connects the cognitive subject and the cognitive object to improve accuracy, and accelerates the development of cognition (Flow: The Psychology of Optimal Experience (Harper Perennial Modern Classics): Mihaly Csikszentmihalyi: 9780061339202: Amazon.Com: Books 2022).
In "Virtual Reality Theory and Practice," Zhang Boping provides an analysis of key virtual reality technologies, combines human-computer interaction and 3D modeling technology to design and realize various virtual reality applications, and presents relevant design strategies for virtual reality display projects, which can be a useful reference for designers and researchers alike (Zhang and Wang 2021).
In order to fill the research gap in the literature the proposed work lies in the integration of machine learning and metaverse technologies to create a secure and enriching preschool education environment.While the concept of the metaverse and its potential applications have been explored, the specific focus on utilizing machine learning algorithms to enhance personalized learning experiences for young children in the metaverse is relatively novel.
By leveraging machine learning algorithms, the educational content within the metaverse can be tailored to meet the unique needs and progress of each preschool learner.This personalized approach can optimize the learning process, adapt to individual learning styles, and provide targeted support to maximize educational outcomes.
Furthermore, the emphasis on cybersecurity within the metaverse context is a critical aspect of the work's novelty.As the metaverse becomes more integrated into our daily lives, including education, ensuring the privacy and security of young learners becomes paramount.This work recognizes the importance of addressing cybersecurity concerns and proposes the implementation of robust security measures to protect user identities and personal data and maintain a safe digital environment.
In summary, the novelty of this work lies in the integration of machine learning algorithms and metaverse technologies to enhance personalized learning experiences for preschoolers while simultaneously addressing cybersecurity concerns to ensure a secure educational environment.By combining these elements, the work aims to contribute to the emerging field of metaverse-enabled education and promote a safe and enriching learning environment for young learners.

Basic Attributes of the Metaverse
The Metaverse is a term used to describe a virtual universe that is a shared space created by the convergence of physical and virtual reality.While there is no single definition of the Metaverse, it is generally characterized by several key attributes: (1) Persistent: The Metaverse is persistent, meaning that it exists continuously and is always accessible.It is not a temporary space that disappears once users leave.
(2) Shared: The Metaverse is a shared space that is open to anyone who wishes to participate.Users can interact with each other in real-time, regardless of their physical location.
(3) Scalable: The Metaverse is highly scalable and can support a large number of users simultaneously.It can accommodate a vast range of activities and experiences, from simple interactions to complex transactions.(4) Immersive: The Metaverse is highly immersive, providing users with a sense of presence in a virtual world.This is achieved through advanced technologies such as virtual and augmented reality.(5) User-generated: The Metaverse is largely user-generated, meaning that users can create their own content and experiences within the virtual world.This allows for a high degree of customization and personalization.(6) Persistent Identity: Users in the Metaverse have a persistent identity that they can carry across different experiences and activities.This allows for greater continuity and coherence within the virtual world.(7) Interoperable: The Metaverse is designed to be interoperable, meaning that different virtual worlds and applications can connect and interact with each other seamlessly.This allows for greater flexibility and variety within the virtual universe.
Overall, the Metaverse is a dynamic and evolving concept that is constantly changing and adapting to new technologies and user needs.As such, these attributes are subject to change as the Metaverse continues to evolve.
In the year 2021, the notion of a "metaverse" gained global attention after originating in the United States.The metaverse, at its core, encompasses Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), with the added advancement of digital twin technology that allows for the creation of a virtual world that mirrors our own.This convergence of technologies is set to revolutionize the way we interact with digital spaces, offering new forms of engagement and immersion that were previously impossible.The implications of the metaverse are far-reaching, as it has the potential to impact numerous fields, including entertainment, education, commerce, and social interaction, among others.As we continue to explore the possibilities of this emerging technology, it is clear that the metaverse represents a significant milestone in the evolution of human-computer interaction and holds great promise for the future (Almarzouqi, Aburayya, and Salloum 2022;Park and Kim 2022).
In the year 2021, the notion of the "metaverse" was still in its nascent stage and could be considered as a prototype, with its features being largely derived from prevalent technological domains like virtual reality.Nonetheless, the future architecture of the metaverse is expected to be distinct from that of existing immersive virtual spaces and possess unique attributes of its own.The ramifications of the metaverse on the human information architecture are anticipated to be profound and far-reaching.In terms of interaction design, novel approaches for virtual space audio-visual design, information architecture design, user behavior design, and user emotion design are likely to emerge (Wang et al. 2022;Yang et al. 2022).
The metaverse has the potential to revolutionize traditional teaching scenarios, enabling the creation of teaching scenarios that incorporate presence, gamification, perception, and autonomy.This presents significant opportunities for education and teaching reform, but also challenges that the education industry must address.Scholars have highlighted the importance of developing a basic model for the construction of learning scenarios in the metaverse (Chang, Yeh, and Li 2020;Park and Kim 2022;Zhang and Wang 2021).
Presence is a fundamental attribute of the metaverse that allows users to experience teaching scenarios in a way that breaks the limitations of time and space.Virtual reality teaching environments create an interface that is conducive to promoting interaction, laying a strong foundation for the implementation of interaction.Gamification is also an important attribute that allows for the incorporation of interactive and game-like elements into teaching scenarios.In the current 5 G network environment, real-time interaction and feedback become possible, enabling students to learn and provide feedback independently through gamified teaching content.
Perception is another key attribute that enriches the interactive process of the metaverse.It includes various perceptual sensations such as touch, taste, smell, and motion, which can enhance information transmission and feedback and strengthen the depth of the application of virtual reality technology.Autonomy is a symbolic attribute of the metaverse, enabling the construction of teaching scenarios that can be completed by both teachers and students.
This allows for scenarios to be teacher-led at the beginning and later studentled, reflecting the autonomy of the teaching subject.It also enables the implementation of "Inverted Classroom" and "Student-centered" teaching models.
Finally, the community attribute of the metaverse is closely related to user activity, interaction frequency, and interaction efficiency.As such, the development of the metaverse will be closely tied to the strengthening of community attributes.This will promote a closer relationship between the metaverse and people, further increasing its potential for transforming education and teaching scenarios.

Research on Interaction Patterns in the Metaverse
The metaverse is a complex and rapidly evolving concept that encompasses a wide range of interactive experiences and applications.As such, research on interaction patterns in the metaverse is a critical area of investigation for scholars in the fields of education, computer science, and human-computer interaction.
One approach to studying interaction patterns in the metaverse is to examine the different types of interactions that occur between users and the virtual environment.For example, researchers may look at how users navigate and interact with virtual objects, how they communicate with other users in the virtual environment, and how they interact with non-player characters (NPCs) or other forms of artificial intelligence.
Another approach to studying interaction patterns in the metaverse is to focus on the different types of social interactions that occur between users.These may include traditional forms of social interaction, such as chatting or sharing information, as well as more complex forms of interaction, such as collaborative problem-solving or joint exploration.
A third approach to studying interaction patterns in the metaverse is to examine how different types of interactions impact user engagement and learning outcomes.For example, researchers may explore how different types of interaction patterns affect user motivation, attention, and retention of information.
Overall, research on interaction patterns in the metaverse is a critical area of investigation that can help us better understand how users engage with virtual environments and how we can design more effective and engaging learning experiences in this exciting and rapidly evolving technology.
In the teaching process, teaching interaction exists at several different levels.These levels can be broadly categorized as follows (Almarzouqi, Aburayya, and Salloum 2022;Zhang and Wang 2021): (1) Teacher-Student Interaction: This is the most common and basic form of teaching interaction, and it occurs between the teacher and individual students or groups of students.It involves the teacher presenting information, answering questions, and providing feedback to students, and the students responding by asking questions, participating in discussions, and completing assignments.( 2 By understanding these different levels of teaching interaction, educators can design more effective and engaging learning experiences that promote student learning and engagement.The development of effective teaching scenarios primarily depends on the interplay between instructors and students.The central component of constructing a model of teaching scenarios entails the interaction among students, media interfaces, educational resources, teachers, and the exchange of old and new concepts, resulting in a tri-level effect.Ongoing advancements in interactive technology have expanded the range of teaching interactions.The fundamental characteristic of utilizing interactive technology in education is the genuine engagement of students, which moves beyond passive learning from instructors, textbook knowledge, rote memorization, and simplistic learning tactics.Instead, students become actively involved, open-minded, analytical, and practical in their learning approach.The application of interactive technology manifests diverse interaction modes, which signify the explicit ways and techniques employed to facilitate interaction, including input mechanisms such as mouse and keyboard, feedback mechanisms such as images, text, audio, and video, as well as animations.The study of interaction models integrates interaction modes and teaching approaches at varying technical levels within a teaching scenario (Almarzouqi, Aburayya, and Salloum 2022;Zhang and Wang 2021;Zhu et al. 2020).
Currently, network technology has facilitated the integration of interactive technology in all facets of teaching activities.Online teaching, due to its inherent "online" nature, features online functionality, absence of spatial constraints, capacity for multi-user parallelism, immediate recording of teaching content, and prompt information feedback.Novel technologies, such as virtual reality and H5 interactive web page development, have been integrated into the development of online teaching, extending classroom teaching resources and augmenting online pedagogical tools through their distinctive visual presentation and information interaction modes.
The metaverse has the potential to extend classroom teaching resources and enhance online pedagogical tools by providing unique visual presentations and information interaction modes.It offers a virtual world that can be accessed from anywhere, allowing students and teachers to connect and collaborate in a shared space.Through the metaverse, teachers can create immersive learning environments that simulate real-world experiences and engage students in a more interactive way.For example, students can explore virtual museums, participate in simulations, or visit historical landmarks, all from the comfort of their own homes.Moreover, the metaverse can facilitate social learning by enabling students to interact with one another and collaborate on projects, regardless of their physical location.This fosters a sense of community and enhances student engagement, which is crucial for effective learning.
The metaverse can revolutionize online education by providing a more immersive and interactive learning experience, extending classroom teaching resources, and augmenting online pedagogical tools.
The metaverse's basic model can be utilized to analyze the application patterns of constructing learning interaction across various types of learning scenarios.This approach has been explored by researchers such as Al-driven methodology (Al-Dojayli and Czekanski 2017; Almarzouqi, Aburayya, and Salloum 2022).
Firstly, the metaverse provides an immersive experience for learners.It allows them to engage in virtual environments that simulate real-world experiences, which can enhance their understanding and retention of course material.Secondly, the metaverse can be used to follow real-world teaching scenarios.For instance, learners can participate in simulations that mirror real-life situations, allowing them to apply their knowledge in a practical setting.Thirdly, the metaverse facilitates the superposition network interaction habits.This means that learners can connect and collaborate with peers and instructors from all over the world, thereby fostering cross-cultural communication and expanding their perspectives.Finally, the metaverse can enable a combination of timely feedback and delayed feedback.Learners can receive immediate feedback on their performance through real-time interactions, and also receive feedback after completing tasks or assignments, which can help reinforce learning and improve their overall performance.
In summary, the metaverse's basic model can be leveraged to construct learning interactions in various types of learning scenarios.It offers an immersive experience, mirrors real-world teaching scenarios, facilitates superposition network interaction habits, and provides a combination of timely and delayed feedback.

Metaverse Cybersecurity Challenges
Here are some of the most prevalent security threats in the metaverse universe (Alromaihi, Elmedany, and Balakrishna 2018;Chiou et al. 2021;Porambage et al. 2021): (1) Moderation.Most metaverses have no access to aid or support.
Nonfungible token theft, for example, may deprive a user of authorization.
(2) Identity.Identity spoofing, account hacking, and avatar takeover are all possibilities for Metaverse users.The essence of the person metaverse users are interacting with is always a source of contention.(3) Client vulnerabilities.Vulnerabilities of the client VR and AR headsets are powerful computers with a large amount of software and memory.They are also prime candidates for both purposeful and unintentional hacking.Furthermore, location spoofing and gadget manipulation allow offenders to steal users' identities and wreak havoc once they join the metaverse.(4) User-to-user communications.Because the metaverse experience promotes user-to-user contact, these connections are created via trust and trade.A single terrible actor may wreak havoc.The need for scaled moderation is crucial and must be addressed.(5) Data precision.The correctness of location, goods quality, reviews, user information, and reliable third-party data is anchored.It might be challenging to ensure correctness.(6) Privacy.There are no metaverse rules, and the requirement for data collecting for a genuinely tailored immersive experience necessitates a breach of confidentiality.However, most users are unaware of the volume of data they are supplying.In addition, unlike GDPR and other legislation that demand regional sovereignty, virtual experiences have no boundaries.As a result, maintaining privacy is at the discretion of the platform owner and property owners.
Also, there are several security problems to VR and AR technologies.
Companies should address extra hurdles when adopting the metaverse in VR and AR settings (Han et al. 2010;Zhang et al. 2020).These are some examples.

VR Security Issues
(1) Reliance.Because the owner of a metaverse product or platform owns it, all users of the product/platform depend solely on the metaverse owner.
Early adopter firms, for example, who elected to utilize Second Life, had to rely entirely on that platform for security, identity protection, privacy, and even financial transactions.
(2) Responsibility.The property that users purchase or rent in a virtual reality environment poses several security and privacy issues that must be addressed.Who is permitted to enter or is barred from entering the property?Is the property owner allowed to select who may and cannot enter?What occurs within these buildings?Could there be financial or illicit dealings inside?(3) Authentication.It is difficult to determine whether or not an entity is who they claim to be.How can you know whether the person you're talking to is who they say they are?Take, for example, telemedicine.How does a patient know if the person they interact with is a medical professional?How can a property owner ensure that a doctor has the qualifications before enabling them to practise?(4) Accountability.Is the owner of the VR environment liable if fraud, harassment, or other types of abuse occur?(5) Privacy.There are currently no rules in place for VR settings.Given the metaverse, the intrusive data gathering and analysis of VR platform owners, and the fact that a lot of data is regularly exchanged by users unbeknownst to the VR user, rules will emerge.However, the platform owner now has complete control over the security and distribution of this data.(6) Advertisement feeds.Unlike, in the real world, where an ad banner could appear in front of your actual business, virtual adverts might appear in front of your virtual storefront.Your clients may or may not like these advertisements, but you do not influence them.The owner of the metaverse has total control over this.(7) Privileged accounts and hacking.The hack of customer support or admin accounts may result in a massive compromise of a VR environment, which, if uncovered, may hurt many users.(8) Access point compromise.Because most people enter the VR metaverse through a headset, a total takeover of that user's avatar might occur amid the headgear terminus.
(4) Secure Communication Protocols: Utilizing secure communication protocols, such as Transport Layer Security (TLS) or Virtual Private Networks (VPNs), can introduce additional memory and computational overhead.These protocols encrypt communication channels, which can increase memory usage and computational demands during data transmission.( 5) Security Audits and Vulnerability Assessments: Performing security audits and vulnerability assessments to identify potential weaknesses and address security risks can require additional computational resources.Scanning systems, analyzing logs, and running security tests can impact memory usage and processing capabilities.
It is important to note that advancements in technology, such as hardware acceleration and optimization techniques, can help mitigate the impact on memory and computational resources.Additionally, the choice of efficient algorithms and implementation strategies can minimize resource usage while maintaining a high level of security.Ultimately, the trade-off between the enhanced security provided by the comparative methods and the increased resource occupation needs to be carefully considered.It is important to strike a balance that ensures an acceptable level of security while optimizing resource utilization to provide a smooth and efficient user experience within the metaverse environment.

Secure Suggestions and Scenarios
Secure preschool education using machine learning and metaverse technologies is a promising approach that can provide a safe and engaging learning environment for young children.Here are some detailed suggestions on how this can be achieved: (1) Use machine learning for early detection and prevention of potential risks.Machine learning algorithms can be trained to detect and prevent potential risks that may harm children, such as cyberbullying, online predators, or inappropriate content.By analyzing patterns of behavior and content, these algorithms can provide real-time alerts to teachers and parents, enabling them to take immediate action and prevent harm.
(2) Provide a secure virtual environment through the metaverse.The metaverse can provide a secure virtual environment for preschool children, allowing them to learn and play in a safe space that is monitored by teachers and parents.Teachers can create virtual classrooms where children can interact and learn through immersive experiences, such as virtual field trips or interactive simulations.
(3) Facilitate parent-teacher communication through the metaverse.The metaverse can also facilitate communication between parents and teachers, providing a platform for them to share information about a child's progress, concerns, and feedback.This can enhance the partnership between parents and teachers, which is crucial for a child's development.(4) Utilize machine learning to personalize learning experiences.Machine learning algorithms can also be used to personalize learning experiences for preschool children.By analyzing a child's learning style, interests, and performance, these algorithms can recommend customized learning activities and resources that suit each child's needs.(5) Incorporate gamification and interactive learning experiences.To engage preschool children, it is important to incorporate gamification and interactive learning experiences that are fun and engaging.The metaverse can provide a platform for creating interactive and immersive games that can teach children important skills and concepts in a playful and engaging way.
Here's an example scenario of how secure preschool education using machine learning and metaverse technologies could work in practice: Mrs. Lee is a preschool teacher who uses a virtual classroom in the metaverse to teach her students.Her students, aged between 3 and 5 years old, log in to the virtual classroom from their homes, where they can interact with each other and participate in various learning activities.Using machine learning algorithms, Mrs. Lee is able to personalize the learning experiences of each child.For example, the algorithm may recommend different learning activities or resources based on a child's learning style, interests, and performance.This enables Mrs. Lee to create a tailored curriculum that meets the unique needs of each child.
To ensure the safety and security of her students, Mrs. Lee also uses machine learning algorithms to detect and prevent potential risks.The algorithms can analyze patterns of behavior and content, providing real-time alerts to Mrs. Lee and parents if any potential risks are detected, such as cyberbullying or inappropriate content.Also, through the metaverse, Mrs. Lee can also provide an engaging and interactive learning experience for her students.For example, she can take her students on virtual field trips to different parts of the world, allowing them to explore and learn about new cultures and environments.She can also use gamification to make learning fun and engaging, creating interactive games that teach important skills and concepts.
The metaverse also facilitates communication between Mrs. Lee and parents, enabling them to share information about a child's progress, concerns, and feedback.This enhances the partnership between parents and teachers, allowing them to work together to support the child's learning and development.So, through the use of machine learning and metaverse technologies, Mrs. Lee is able to create a secure and engaging learning environment for her preschool students, where they can learn and grow safely and effectively.
In addition, here are some methods that can be used to develop the scenario of secure preschool education using machine learning and metaverse technologies: (1) Research and analyze the needs of preschool education.Before developing the scenario, it is important to research and analyze the needs of preschool education.This includes understanding the developmental needs of young children, the challenges and risks associated with preschool education, and the role of technology in supporting learning and development.
(2) Identify suitable machine learning algorithms.Identifying suitable machine learning algorithms is essential for developing a secure and effective learning environment.This involves researching and evaluating different algorithms that can detect and prevent potential risks, personalize learning experiences, and provide real-time feedback to teachers and parents.
(3) Choose a suitable metaverse platform.Choosing a suitable metaverse platform is also important for creating a secure and engaging virtual learning environment.This involves researching and evaluating different platforms that can provide a safe and interactive space for preschool children to learn and play.(4) Collaborate with preschool educators and parents.Collaborating with preschool educators and parents is essential for developing an effective scenario.This involves working closely with educators and parents to understand their needs and preferences, and incorporating their feedback into the scenario design.(5) Develop and test the scenario.Once the research, analysis, and collaboration stages are complete, the scenario can be developed and tested.This involves designing and creating the virtual classroom, implementing the machine learning algorithms, and testing the scenario with preschool children and their parents to ensure that it is effective, engaging, and safe.(6) Iterate and improve the scenario.Finally, it is important to iterate and improve the scenario based on feedback from preschool educators, parents, and children.This involves continually evaluating and improving the machine learning algorithms, metaverse platform, and learning activities to ensure that they meet the evolving needs of preschool education.
In summary, secure preschool education using machine learning and metaverse technologies can provide a safe and engaging learning environment for young children.By using machine learning for early detection and prevention of potential risks, providing a secure virtual environment through the metaverse, facilitating parent-teacher communication, personalizing learning experiences, and incorporating gamification and interactive learning experiences, we can ensure that preschool children have a positive and effective learning experience.

Establishment of Technical Ethics and Relevant Laws and Regulations
The future development of the metaverse is the rapid iteration and independent innovation of technology.The development experience of the Internet proves that technology does not evolve ethics, so it makes great sense to root the concept of " Tech for Social Good" in the metaverse.The application of metaverse to teaching scenario construction should also be studied from the perspective of technology ethics (Moor 2001).
On the one hand, the development of science and technology has brought progress and prosperity to human society.On the other hand, it has also generated many serious problems that cannot be solved by science and technology.Since ancient times, the development of human civilization has started from "trial and error."Teaching behaviors in the metaverse inevitably have the adaptive phase phenomenon of unclear direction (Siyaev and Geun-Sik 2021;Wang et al. 2022).We must be careful to avoid losing our way, so that the application of the metaverse can be moved forward in a more stable way.
Science fiction writer Hao Jingfang believes that now is a "defensive type of goodness," and there should be a "creative type of goodness" in the future (Amazon.Com: Vagabonds EBook : Jingfang, Hao, Liu, Ken: Kindle Store 2022).As for "Tech for Social Good," she thinks that what needs to be done more in the future is to take the initiative to create, and we are still doing "defense" a lot of times now, or trying to prevent technology from doing bad things.In the future, we need a creative development idea, that is, in the stage of scientific and technological research and development, we need to seek development "needs" in the direction of the goodness of human nature and the goodness of society.That is, the establishment of laws and regulations in the metaverse can be determined before the large-scale application of the metaverse, rather than waiting until the application of the metaverse is rolled out on a large scale to discover problems (Alzubaidi et al. 2021).

Discussion
The proposed method of leveraging machine learning and metaverse technologies to create a secure and enriching environment can be e2222496-2068 Q. ZHANG applied to other domains beyond preschool education.While the focus of the article is on preschool education, the underlying principles and techniques can be adapted and extended to various other fields and industries.For example, in the field of higher education, the integration of machine learning algorithms and metaverse technologies can revolutionize remote learning experiences.By personalizing educational content, virtual lectures, and collaborative activities within the metaverse, students can have interactive and immersive learning experiences that cater to their specific needs and preferences.Additionally, the implementation of robust cybersecurity measures ensures the privacy and protection of sensitive student data and intellectual property.
In the realm of healthcare, the use of machine learning and the metaverse can enable innovative medical simulations and training scenarios.Healthcare professionals can practice complex procedures and interact with virtual patients, enhancing their skills and knowledge in a safe and controlled environment.Again, cybersecurity measures are crucial to protecting patient data and ensuring the integrity of the simulations.
