This is the first in a series of Sway notes for the module ES2660 – Communicating in the Information Age. It provides information which sets the context for the lesson taught in the class tutorial. There are links to other relevant resources that students may go to in order to read more on the subject. The material here replaces what used to be tutorial ‘handouts’. Sway allows images, slides, videos and links to optional resources to be embedded in a single interactive document, so that this serves as an ‘all-in-one’ place for course materials. Even instructions for homework and assignments are included here.
