Several elements of global learning were already present in our ECE curriculum, but were not formalized or assessed. The most common were: (a) Discussion of historical background of course topic; (b) Sustainability, in the form of efficient design or use of resources (for example, mini- mized logic, efficient code or spectrum usage). 2.
