In addition, Education 4.0 emphasizes the integration of cutting-edge technologies like artificial intelligence, virtual reality, augmented reality, and big data analytics into the learning process. It also focuses on fostering critical thinking, creativity, collaboration, communication, and digital literacy skills among students to prepare them for the demands of the modern workforce and society.

In simple terms, Education 4.0 is about using advanced technology to make learning more interactive, personalized, and relevant to the needs of today’s world, while also emphasizing important skills needed for success in the 21st century.

What is Higher Education 4.0?

Higher Education 4.0, also known as the Fourth Industrial Revolution in education, emphasizes a student-centered approach with a focus on technology, critical and creative thinking, and real-world application of knowledge (Goh & Abdul-Wahab, 2020). Virtual reality and augmented reality are emerging technologies that hold immense potential in the new digital age. They have emerged as innovative technologies that are revolutionizing the landscape of higher education in what is commonly referred to as Higher Education 4.0.

The use of AR and VR in higher education can help create interactive educational atmospheres that engage learners both physically and virtually. These technologies can replicate real-life scenarios, allowing students to develop specific skills based on their academic syllabuses (Sterev, 2023). VR and AR offer exciting possibilities for transforming traditional teaching methods (Venelinova et al., 2024). Hence, they play a crucial role in providing learners with access to information 24/7, enabling them to actively seek knowledge rather than passively receiving it from textbooks or instructors. The integration of 360-degree real-life videos and VR technologies in teaching advanced communication skills to students at universities.

2.2. Understanding Virtual and Augmented Reality in Education

Virtual Reality (VR) and Augmented Reality (AR) are transformative technologies that are reshaping educational methodologies. Both fall under the umbrella of Extended Reality (XR), and they offer unique benefits that enhance learning experiences.

What is Virtual Reality?

VR immerses the user in a virtual world, providing a sense of presence and allowing for a more realistic and immersive experience (Beck, 2019). With VR, students can be transported to virtual environments that simulate real-world scenarios, allowing them to apply theoretical knowledge in practical settings. This experiential learning approach can be particularly valuable for disciplines such as science, engineering, and healthcare, where hands-on experience is crucial.

What is Augmented Reality?

AR can overlay digital information onto the physical world, creating a blended learning experience that merges the virtual and real environments (Beck, 2019). This can be used to provide contextual information, interactive demonstrations, or virtual models, enriching the learning process.

2.3. The role of VR/AR Technology in Higher Education

Technology plays a vital role in Higher Education 4.0. It gives students access to digital information and resources, facilitates collaboration and communication, and enables personalized and adaptive learning experiences.

It also prepares students for the future workforce, where technology skills are increasingly in demand (Vergara et al., 2021).

According to Ding & Li (2022), VR/AR has been used to enhance general learning experiences. For example, virtual field trips have been created to provide students with immersive experiences of historical sites, natural landscapes, and cultural landmarks. These virtual experiences not only supplement traditional classroom learning but also make it possible for students to explore places that would otherwise be inaccessible.

Virtual Reality in Higher Education 4.0

Virtual Reality is particularly well-suited for Higher Education 4.0 as it aligns with the goals of providing a personalized and immersive learning experience. In Higher Education 4.0, students are encouraged to take an active role in their education, and VR can facilitate this by offering interactive and customizable learning experiences. Whether it’s exploring the human anatomy or practicing complex engineering concepts, VR can provide students with hands-on experiences that would otherwise be inaccessible (Marks & Thomas, 2022).

In Higher Education 4.0, the focus is on developing critical and creative thinking of student, and problem-solving skills. Virtual reality offers an almost entirely safe environment that is pre-controlled by developing virtual content that allows students to experiment, make successes or mistakes, and learn from their own experience. It allows for trial and error without real-world consequences, enabling students to develop their problem-solving abilities in a risk-free environment.
