here are normally two types of training media within a learning program. The first is the instructional setting or major media. For example, you might have your learners go to classroom training for 2 days or have an elearning program delivered to them. The second is the delivery systems within the major medium. These are the various instructional methods that take place within the instructional setting. In the two day class you might have several types of media, such as lectures, videos, programmed instruction, coaching, etc. Another example is an elearning platform with several types of media within it, such as videos, readings, and simulations incorporated into it.
