I think that the concept of the ERWC “Arc” is important to help teachers understand the fundamental pedagogical concepts of ERWC and to help students internalize the concepts so that they can transfer them to other rhetorical situations.  To promote this concept, I created a handout, which has been formatted and enhanced by my wife HeeJung.  Here is an image of it:

The handout illustrates the concepts of “Text to Text” and the progression of tasks built in to every ERWC module.   Download a .pdf version here: ERWC Arc Handout.
