  Computing technologies have become pervasive in daily life, sometimes
bringing unintended but harmful consequences. For students to learn to think
not only about what technology they could create, but also about what
technology they should create, computer science curricula must expand to
include ethical reasoning about the societal value and impact of these
technologies. This paper presents Embedded EthiCS, a novel approach to
integrating ethics into computer science education that incorporates ethical
reasoning throughout courses in the standard computer science curriculum. It
thus changes existing courses rather than requiring wholly new courses. The
paper describes a pilot Embedded EthiCS program that embeds philosophers
teaching ethical reasoning directly into computer science courses. It discusses
lessons learned and challenges to implementing such a program across different
types of academic institutions.
