IV. NEED OF VIRTUAL LABS

The increasing demand for virtual laboratories in modern education is driven by the limitations of traditional lab settings, particularly concerning accessibility, safety, and costs. Virtual labs offer unprecedented flexibility, enabling students to perform experiments at their own pace, from anywhere, and without the need for physical lab space. This flexibility is particularly important in scenarios where traditional labs are inaccessible, such as during health crises like the COVID-19 pandemic. Additionally, the safety features of virtual labs allow students to explore potentially dangerous or expensive experiments in a risk-free environment, encouraging exploration without real-world consequences. Another compelling reason for the shift to virtual labs is the cost-effectiveness they offer compared to traditional setups. Physical laboratories require significant investments in equipment, materials, maintenance, and compliance with safety standards. Virtual labs eliminate these costs by consolidating resources into a single, scalable platform, reducing the need for duplicate equipment and maintenance.

This reduction in expenses makes it easier for educational institutions to provide high-quality learning experiences while allocating funds to other areas of need, making education more accessible and equitable for all students.

In addition to being cost-effective and accessible, virtual labs improve student engagement and learning outcomes through interactive simulations that cater to various learning styles. Research has shown that students who engage with virtual labs exhibit higher levels of motivation and conceptual understanding than those in traditional settings. The immersive nature of these simulations allows students to visualize complex scientific phenomena, practice repeatedly, and receive immediate feedback, leading to deeper learning. By facilitating experiments that might be too costly, dangerous, or impractical in a physical setting, virtual labs offer an innovative solution that enhances STEM education and prepares students for a digitally-driven future. As the demand for flexible, scalable, and engaging educational tools continues to rise, virtual labs are poised to play a crucial role in shaping the future of learning.

Conclusion

Virtual Labs remain an emerging and evolving approach to laboratory-based engineering education. The present study investigates the perceptions of potential-adopter educators regarding the concept of critical mass for Virtual Labs, highlighting key factors such as Relative Advantage, Ease of Use, Perceived Enjoyment, and Departmental Support as the most influential. Interestingly, Peer Influence was not found to be a significant factor in the adoption process. Critical mass is defined as the point at which a sufficient number of individuals have adopted an innovation, leading to a self-sustaining rate of adoption. While determining the precise moment when critical mass is reached can be challenging, understanding how potential adopters perceive the innovation’s trajectory toward reaching this point is invaluable. This study emphasizes that achieving critical mass among potential-adopter teachers is crucial for the continued success and sustainability of a technological innovation like Virtual Labs. From a practical standpoint, the findings of this study can serve as a guide for educational policymakers and higher education institutions in establishing or refining their virtual learning platforms, such as Virtual Labs. However, the study’s scope is limited by time, as the adoption process, according to Rogers, is not immediate but rather a gradual evolution. Future research could explore the global adoption of Virtual Labs, considering the potential impact of demographic and cultural factors.
