This paper examined the influence of interdisciplinary education on technology and society over engineering identities of male and female students. For this purpose, we analyzed survey and essays of UNIST students who took the course of in 2013. Favorable feeling toward engineers, satisfaction with future career as engineers, positive regards of engineers' contribution to society increased to a statistically significant level within the group of female students who took the course. Interestingly, male students also formed more positive engineering identities after taking the course. Gender difference in engineering identities, which was statistically significant within the control group of non-takers, disappeared within students who took the course. Both male and female students learned to perceive engineering as a goal-oriented and contextualized exercises that can materialize new social values. In conclusion, interdisciplinary education on technology and society can make positive impacts on students' formation of engineering identities and sense of commitment.
