The aim of this paper is to propose that engineering ethics education should be regarded as an essential component of a values-sharing program of the engineering community. The authors claim that the concept of “values-sharing” can be utilized in order to avoid unnecessary impediments associated with negative connotations of “ethics” in postwar Japan and promote a systematic development and implementation of engineering ethics education. The process of engineering ethics education is reconstructed as a continuous process of values-sharing with so-called PDCA (Plan-Do-Check-Act) cyclical stages. The authors examine issues related to each stage such as the needs for redefinition of educational objectives, the case-method as a promising pedagogy, and the challenges in assessment and evaluation for engineering ethics education.
