Abstract-The advance of Information and CommunicationTechnology (ICT) and the reduction of cost in digital applications motivate course designers to develop new application of distance learning programs so as to meet the increasing educational needs in the knowledge-based society. As a consequence, distance learning courses are increasing in number, credibility and acceptability all over the world. The question is whether these programs are efficient in terms of costs. The main theme of this work is to investigate cost behaviour and estimate cost efficiency of distance learning courses applied in low-inhabited, remote islands. The target group consists of high school students of Grade I. The distance learning course that is designed uses several scenarios of the "what-if form" and reaches the conclusion that cost of such solutions is far lower than that of any traditional course, even at the absence of scale economies.Index Terms-Cost efficiency, cost effectiveness distance learning, remote islands.
I. INTRODUCTION In the modern world Information and CommunicationTechnology (ICT) has penetrated dynamically in the field of education, supporting wide categories of educational programs that range between those entirely depending on technology and those based on traditional teaching and learning approaches. In the former case ICT provides a tool "sine qua non", while in the latter ICT is used as a tool that supports traditional educational methods in order to upgrade quality and improve the programs' effectiveness.An important category of programs that depend critically on ICT is that of distance and online education. In its contemporary sense, it consists of innovative instructional applications in which the teacher and the learner are separate in space and, possibly, in time, while technologyincluding the Internet-is engaged to act as the mediator that facilitates communication and interaction between the learner and the distant teacher [1].Despite the fact that technology is becoming increasingly important in education, and although the promises of distance learning are to a great extent financial in nature, cost issues in relation to ICT have not been studied as extensively as other matters referring to distance education [1]. It is only after the mid-1990s that cost issues in distance learning have attracted the interest of researchers. Even then, opposite to other areas of distance education, research in cost issues has not shown any spectacular explosion. The delay could be attributed to the fact that research questions concerning cost efficiency of distance learning are worth investigating only if the battle for rec-
