The purpose of this study is to analyze the characteristics of the English learning strategies of the students who participated in flipped class and to develop teaching methods to induce the students’ learning strategies. For this purpose, 108 high school students responded to the English learning strategy questionnaire and a confirmatory factor analysis was conducted based on the results. Through the confirmatory factor analysis, the characteristics of four English learning strategies such as exploring, fulfilling, demanding and sharing were confirmed. The verified characteristics were statistically significant by examining goodness fit. Students have a strong tendency to constantly try new learning methods; exploring, strive to obtain visible performance and substantial rewards; fulfilling, maintain a constant attitude of seeking and collaborating with friends and teachers around them; demanding, and tried to share learning contents; sharing. Considering the characteristics of these learning strategies, teachers in flipped class need to develop an assessment system that provides students with reconstructed textbooks in various aspects, give them instant and continuous learning achievement, provide active feedback, and create a learning atmosphere where project learning can be organized efficiently.
