Abstract: Life education for college students is a lasting topic of the times,and it is an important part of mental health education in colleges and universities.From the  analysis of perspective of responsibility ethics,the problems in college students' life education in the new era are mainly reflected in the lack of responsibility thinking of educational subjects,the lack of coordination of multiple responsibility subjects,the weak awareness of individual responsibility ethics,and the poor operation system of responsibility ethics and so on.At present,to strengthen the construction of responsibility ethics of college students' life education,we should fully follow the operational logic of life education,which takes cognitive understanding as the premise,internalization of identity as the core,and externalization of practice as the end-result.

Key words: college students, life education, responsibility ethics
