Extant materials are already available (created or made) and ready to be picked.
Elicited are materials that a researcher gleans from researchees in real time or through a direct interaction with the participants.
Enacted calls for researcher and participants to create the data, such as you would do with role playing or arts-based research.
I am embarrassed to say how many hours I have spent writing notes and drawing diagrams as I tried to figure out how to find a simple way to categorize the many possible forms of research one can find or create. It’s even more complicated when you try to figure in how to work with face-to-face vs online or virtual data collection.
When I discovered Salmon’s three E’s, I was momentarily stunned (Why hadn’t I thought of this!), but then elated because I could stop the endless quest for the framework that constantly eluded me.
I want to say “Thank you Janet Salmons for creating this way of describing data. I will be using your new book this fall in my Advanced Qualitative Research, and I will be singing the praises of the three “E’s” when I do!”
