The ethical codes of the professional engineering bodies identify the responsibilities of the engineer. Of equal importance to the codes are the virtues which enable the engineer to fulfil these responsibilities.

Central to this learning experience is the development of integrity which focuses the other major virtues and enables reflection upon them. A review of undergraduate courses (...) suggests how this can be achieved. (shrink)
