Education Informatics is a sub-field of informatics. The primary focus is on computer applications, systems and networks that support research in and delivery of education. Education informatics is based upon information science, computer science and education but particularly addresses the intersection of these broad areas. Note that it is distinct from Informatics Education, a term that relates more to the practice of teaching/learning about informatics, rather than the use of information science and technology in the support of teaching and learning. The term has been in use since at least 1980.
