In a technology-rich world, human relations are increasingly mediated through the
interfaces of our digital devices. This is also true for certain arenas of the educational
sector, like online/distance education, where students may traverse a full
learning trajectory without ever physically meeting their instructors or fellow students,
as is the case in distance education. While increasingly sophisticated communication
technologies may coax our senses, the fact remains: if our communication partner is
not really there but physically absent, this will likely have psychological ramifications.
The notion of social presence is one of the most prominent attempts at understanding
the unique psychological properties of mediated communication. It refers to the
degree to which we fall for the illusion of non-mediation, or in other words, our failure
to perceptually integrate what we know in the abstract: That we are talking to a screen. Notably, even in communication media with modest face-to-face fidelity, for example
text-based asynchronous messaging, it is possible to experience relatively high degrees of
social presence. That is, we feel that our communication partner is “real” and “there”.
As evocative and relevant this concept may appear –the sheer volume of studies attest to its popularity–, its practical benefits in advancing our knowledge on the psychology of mediated communication in online distance learning have been relatively small, a fact that may be traced back to a history of inconsistent definitions and the resulting lack of cumulative research progress.
Section A “Introduction and Theoretical Foundations” lays out what we currently do and
don’t know about the psychology of mediated communication, how this relates to online
distance learning and some of its classic issues, as well as the state of research in this
educational arena, with a specific focus on the online environments in which mediated
learning experiences take place. Following this, a thorough review of the concept of social
presence identifies central challenges of the literature and a model to guide the following
steps is proposed.
Section B “Empirical Studies” presents the central research questions of this thesis and
presents five chapters to answer them. As a whole, the quantitative studies within
these chapters are geared toward a better understanding of the phenomenon of social
presence, a more comprehensive theoretical modeling around it, as well as practical
application of this knowledge toward enhancing online distance learning experiences. To
this end, data from a total of 1023 students at FernUniversität in Hagen was collected and
analyzed.
Section C “Discussion and Future Directions” lays out the contributions of this thesis toward the challenges of social presence. Despite some questions remaining unanswered,
the interpretation of findings allows us to conclude that significant progress has been
made toward a better identification, explanation, and application of social presence. As a
visual summary, the final research model is presented in its modified and extended form,
detailing all hypotheses examined in this thesis. Further condensing the findings of this
thesis, a set of questions informing a tentative theory of social presence are answered
succinctly. Through these summaries on different levels of elaboration, we learn that social
presence is a complex psychological phenomenon that is multi-causally determined
and nuanced in terms of its benefits for online distance learning. Finally, two frameworks are proposed that may guide future researchers toward major roadblocks on the path to a more coherent and relevant line of research on social presence.
