The main purpose of this paper is to bring pioneering insights into the core line of sustainable education research by investigating the multi-dimensional aspects of teachers’ readiness to design technology-enhanced learning environments. In order to achieve this goal, this study documents the experiences of pre-service English teachers in instructional Virtual Reality (herein, VR) content design of K–12 English digital textbooks. Furthermore, it examines how their VR creation can be linked to a metaverse platform for learning adaptivity and sustainable education. The data are collected by pre-/post-surveys as well as reflective papers. The pre-/post-survey responses are analyzed with a t-test to determine significance; the reflective paper entries are scrutinized with sentiment analysis and text mining. The study findings suggest that such transformative experiences of VR-Making (herein, VRM) for instructional contents are conducive to capacitate pre-service teachers’ technological readiness, 4Cs (Critical Thinking, Creativity, Collaboration, Communication) in digital citizenship, and perceived pedagogical benefits. Based on findings, this study continues to support the need for providing teaching practitioners with hands-on learning-to-teach opportunities with emerging technology as a tool to fulfill sustainable education.

The main purpose of this paper is to add empirical data to the nascent field of metaverse learning and teaching by examining factors affecting student participation and their perceived experiences of different metaverse platforms. For data collection, 57 Korean undergraduates participated in a self-administered questionnaire and a short reflective essay regarding their experiences on three metaverse platforms (ifland, Gather Town, & Frame VR). For data analysis, exploratory factor analysis was first executed to derive the underlying factors that can explain student participation in metaverse platforms. The social and interactive learning as well as individualized and behavioral learning were identified as two main contributing factors. While the three platforms had no statistical difference in terms of social presence, students' sentimentally perceived differences among them. The sentiment analysis shows that 60.00% of ifland users were positive, followed by 53.66% of Frame VR users and 51.22% of Gather Town users. Furthermore, the additional keyword analysis shows why students expressed the perceived experiences of each platform in a different way. Given that the success of metaverse instruction can be dependent upon whether students regard it as beneficial, such measurements of student perception on the effectiveness of learning on metaverse platforms can offer meaningful recommendations for techsavvy educators.
