One of the biggest challenges in discussing elearning arises from different understandings of the field. Most often, we attach our experiences and career to our conversations, presenting an image of elearning that reflects what we have encountered. For an instructional designer, elearning often means courses or learning materials directed at meeting an objective within the larger scope of program development. A corporate trainer may view elearning as a combination of courses and knowledge management. No one perspective is symbolic of the whole industry.

A danger exists in discussing various segments of elearning: paying too much attention to distinctions across categories. The real focus and unifying theme is (or at least should be) learning – whether it is in a classroom, online, blended, or embedded. Each category presented here is most effective when properly matched with the appropriate learning environment and desired outcome.
