The integration of immersive technologies, such as 360-degree virtual reality (VR) in education presents a promising avenue for enhancing teaching and learning. However, educators often face challenges due to limited technical expertise and resource constraints. This study examined the usability and readiness of educators in adopting the 360 VR Educator platform -- a tool grounded in Mayer's (2005) cognitive theory of multimedia learning -- which enables educators to create interactive lessons using 360-degree videos and images. These can be experienced in fully immersive modes (via Google Cardboard and Android smartphones) or semi-immersive modes (via Android tablets). A total of 45 educators participated in a usability evaluation using the System Usability Scale provided qualitative feedback through open-ended responses. The Technology Readiness Index was also employed to assess their adoption readiness. Findings revealed acceptable usability, with educators appreciating the platform's immersive and interactive capabilities. However, some reported difficulties with the interface and navigation. The analysis indicated that optimism and innovativeness significantly influenced platform acceptance. Over 80% of participants expressed willingness to recommend the platform to peers. The study underscores the importance of training and technical support and affirms the potential of 360 VR tools in transforming traditional teaching methods through immersive learning experiences.
