Abstract
This theoretical paper attempts to clarify design issues that the field of education has encountered in the context of OER (Open Educational Resources), Massive Open Online Courses (MOOCs) and increased emphasis on informal learning, as examined through the lens of the Interaction Equivalency Theorem. An overview of the core concepts of the Interaction Equivalency Theorem (the EQuiv) is provided and an explanation of how the EQuiv framework can be used to analyze interaction designs for online and distance education. The paper applies EQuiv ideas to categorize three variants of MOOCs (xMOOCs, sMOOCs and cMOOCs), from the perspective of interaction design so as to elucidate the major design differences. In conclusion, this paper explores the changing role of formal education in an era of learning opportunity where online educational resources and opportunities are readily accessible and in many cases completely free of cost to the learner.
