There are many media strategies, but an instructor should be cognizant of what is relevant to the students, the technical environment of the class, the logistics of the students (are they all living in the same "local" area, or are they all over the world, do they have work schedules that have them working "aroud the clock?"), the material to be covered/learned. The more relevant the assignment/assessment, the more enthusiastic students are to engage in it and have a successful learning experience.
