As one of the teaching methods for educational innovation, the high-flex type of class, which allows flexible learning according to the needs of learners, has recently been attracting attention. The core values of hyflex classes are learner choice, equality, re-usability, and accessibility. Accordingly, in this study, as a way to innovate and improve the quality of university education at a time when it is necessary to develop a new teaching model to prepare for the expansion of online classes in universities and future education, we actually applied hyflex classes to learners at cyber universities. Examples of their learning experiences were analyzed. The research method was conducted using a semi-structured questionnaire and focusing on the learners’ hyflex learning experience through small group and individual interviews. The content of the learning experience interview was divided into 5 components and 12 sub-elements and analyzed as a meaning unit. Based on the research results, the strengths and weaknesses of hyflex classes and points of improvement were derived, and as a new teaching model for innovation in university education, hyflex classes were expanded in various ways and a teaching-learning strategy that could be effectively applied to classes was presented.
