Best label for narrators
I am in the process of developing a couple of StoryLine nursing courses. In both we plan to have a male and female narrator. I am at a loss as to the best term to refer to these narrators, i.e.
"Hi, I am Jill and with me is Mark. We will be your ___________ for this online course."
Possible choices include: instructors, teachers, trainers, mentors, tutors, guides, facilitators, etc.
Which "label" do you use in your online narrated courses?
