In the context of the COVID-19 pandemic, emergency remote teaching (ERT) in vocational colleges has become a point of attention in the academic community. This study adopts qualitative research methods, including content analysis and multiple case studies, to examine the implementation path and encountered problems of ERT in vocational colleges. It examines 326 textual materials and 37 teaching cases related to ERT during a period of home isolation in 89 vocational colleges in Province J, China. The findings revealed that vocational colleges have developed an adaptive path to the construction of ERT spaces, guided by the principles of usability, usefulness, and ease-of-use. The study identified problems related to the construction and implementation of ERT activities. Furthermore, vocational colleges have developed diverse and pragmatic strategies, forming an integrated approach to ERT. This study provides insight on improving the resilience of the higher vocational education system in response to educational crises.
