DEVELOPMENT OF EDUCATIONAL CONTENT IN VIRTUAL REALITY

In the modern world, education plays a key role in the development of the individual and society. However, traditional teaching methods are often not effective enough, especially when it comes to complex and abstract concepts. In this context, virtual reality (VR) offers new opportunities for developing educational content, contributing to improving the quality and accessibility of education.

The purpose of this study is to study the features of educational content development in virtual reality, analyze existing approaches and offer recommendations for the successful implementation of VR technologies in the educational process.

Virtual reality contains the following aspects:

• Functions of using a VR learning application;
• Approaches to the formation of educational content.

There are different types of educational content, such as text, graphics, audio and video content, interactive tasks, exercises, tests and knowledge testing tools. [6, c.11].

The basic functions of the application are interface and navigation, virtual exercises, content mobility and feedback.

When using virtual reality, it is effective to apply various approaches.

Traditional approach: This approach focuses on the transfer of knowledge from teacher to student using textbooks, lectures, presentations, and other sources of information. With the help of tests, it is possible to evaluate the quality of knowledge. In virtual reality, the traditional approach can be used to create theoretical materials, as well as presentations with the availability of interactive interaction with objects.

Problem-oriented approach: This approach focuses on solving real-world problems and challenges faced by students. It creates an environment where students can put their knowledge and skills into practice, as well as gain experience solving real-world problems. This approach can be used to teach various subjects such as history, geography, science, technology, etc. [7, c. 11].

The interactive approach in virtual reality involves creating learning environments where users can interact with virtual objects and the environment while receiving feedback from the system. This approach makes learning more exciting, visual, and memorable. [3, c.15].

A combined approach in virtual reality is the use of mixed reality (MR) technologies that combine the real and virtual worlds. In MR, virtual objects interact with the real world and vice versa. This approach is used in various fields such as manufacturing, gaming, education, and media.

As we have already said, the basic functionality in the virtual reality training application includes several key components:

• Interface and navigation. The interface and navigation in virtual reality are ways for the user to interact with the virtual world and its elements. Various interfaces are used in virtual reality, such as voice, gestures, gaze control, and others. Navigation is performed by moving a character or objects in virtual space [8, p. 55].
• Content mobility in virtual reality means the ability to access content from different devices and platforms. In VR, content must be adapted to work on different devices, such as virtual reality glasses, smartphones, and computers.
• Virtual exercises in virtual reality are workouts that are conducted using special devices such as virtual reality glasses or helmets. They allow you to perform physical exercises in the virtual world, creating a sense of presence and interaction with the environment.
• Feedback. Feedback in virtual reality is a communication tool that helps influence employee behavior. It is divided into two types: supportive and corrective. Supportive feedback allows an employee to realize and repeat the actions that lead him to success, and corrective feedback helps to change the behavior of negatively inclined employees.

The application may also be able to adapt educational content depending on the individual needs and level of knowledge of each user. This allows you to create a personalized learning experience, taking into account the differences in knowledge, skills and preferences of users. [1, c.10].

When using virtual reality, you can use different types of educational content:

Interactive educational games. These can be games aimed at studying specific subjects, such as physics, chemistry, or biology. Games can be of different genres, for example, ACTION, puzzles or simulations. [9, c.108].

Virtual laboratories. These are simulations of real laboratories where students can conduct experiments and study the laws of physics, chemistry and biology.

Excursions and trips. VR allows you to create virtual tours of various places and sites, such as museums, historical sites and nature reserves. Students can explore these places, get information about exhibits and attractions. [5, c.16].

Educational videos and animations. VR allows you to create high-quality videos and animations that clearly demonstrate complex processes and phenomena.

To create educational content in VR, we will need virtual reality helmets, as well as content development software such as Unity, Unreal Engine, and Blender. The most popular virtual reality helmets are Oculus Rift, HTC Viwe and PlayStation VR. They provide full immersion in the virtual world and a high degree of interactivity. [4, c. 48].

In modern education, virtual reality opens up new opportunities for improving learning efficiency. Educational applications based on it offer unique advantages that contribute to the better assimilation of knowledge by students.

One of the key advantages of using virtual reality is to increase the level of engagement and interactivity. VR creates an immersive and interactive environment, allowing students to interact with the world around them and have a realistic experience. In addition, virtual reality develops critical thinking, decision-making and solving practical problems. [2, c.14].

Setting up VR applications with educational content should be flexible and intuitive to meet the requirements of various educational institutions. Teachers and staff should be able to easily change the contents, parameters, and tasks of a VR application, adapting it to the curriculum and the needs of students. Due to the flexibility and ease of setup, virtual reality training programs can be successfully applied in a variety of educational contexts.

The developed data format provides a convenient and structured way to describe the elements of educational content. The script library based on this format provides functionality for programmatically generating learning content, allowing you to upload and process data, create scenes, manage objects, and test and evaluate students' knowledge. [10, c. 2].

Thus, the developed tools for generating educational content in virtual reality-based applications provide opportunities for studying complex subjects such as biology, chemistry and physics, making learning interesting and visual.
