A math class in Korean university was taught in English for one semester and the students' improvement was measured in math content and English proficiency. Pre and post test in 9 week intervals showed that math content loaming in the immersion class was superior to the non-immersed class. Especially, the immersion class showed remarkable improvement in difficult problems among math content test problems. The immersion class improved in math-related English, but not in general English. It is discussed that the particular English expressions for math are hardly separable from the math content knowledge in English because understanding and using those expressions correctly means the students' understanding of math concept in English and thus the math concept itself.

The purpose of this study is to examine the potential of flip learning in Korea and to explore the possibilities of university English education. To this end, participants are sought for classes wherein general English class is taught and the researcher is in charge of teaching. 25 students of media-English class is chosen for the study. Instruments for the study include class evaluation and feedbacks, mid-term and final exams, group performative evaluation, on-line class views and participations. The findings of the study are: As students progress in flipped learning classes, their exam results significantly improved, and their performative evaluation results also improved significant across different groups. The effects are more eminent among higher levels of students, but students with mid and low level of English still improved significantly once they engage themselves in preview activity on a regular basis and self-directedly.
