Does the scenario design course focus only on elearning?

No, the design techniques apply to all types of learning. 

First, action mapping is the technique I recommend for all types of training, so I suggest every project begin with action mapping no matter which delivery format stakeholders feel is best. The current prework for the course that you see when you register is a recorded action mapping presentation that I gave to elearning designers, but the technique applies to all types of learning. 

Second, the design principles for a good scenario are the same no matter which format the final project will take. A scenario question is a scenario question, whether it appears on an elearning screen, is displayed during a discussion session, is a page in a printed booklet being used in small groups, or is a simple text email with clickable links.

We talk about how to run scenarios in face-to-face or other instructor-led situations, and for people who are planning or required to develop elearning, I strongly encourage them to include a live discussion because scenarios are much more effective when participants can discuss them. I actually discourage people from using scenarios as 100% self-paced elearning with no discussion.

The course also recommends creating prototypes, and this step also applies to all delivery formats, because we need some sort of material for learners to focus on, and that material should be tested. The material could be a printed booklet, like a choose-your-own-adventure packet, slides that are displayed in an instructor-led session, or self-paced elearning. In addition, in our discussion of media I discourage the use of bells and whistles and push instead for text-based scenarios that can be used in any type of setting.
