Emerging needs of e-CPS: education

Recognize that while core disciplines need to be well
understood, the research opportunities are emerging
primarily at the intersection of these disciplines.

New knowledge base (yielding new theoretical and
laboratory-oriented courses) needs to be developed that
addresses interdisciplinary and interfacial e-CPS education
and delivered by next-generation e-CPS scholars and
teachers.

Recognize that e-CPS education is a shared responsibility
among industry and academia and requires an open mind
on the part of the students and emerging researchers and
designers.
