The decision to adopt online technology (defined here as predominantly Internet-based delivery, with provision for interaction throughout the process), even on a limited basis, is always complex and can be risky, especially if the adopting organization lacks structural, cultural, or financial prerequisites (Welsch, 2002). A discussion of some attributes of media and of the modes of teaching presentation and learning performance they support, in relation to some influential learning models, might help to clarify some of the implications in the choice of any specific delivery or presentation medium.
