PROBLEM
Rather conducting product evaluation researches about eLearning,
it is important to look at content and field-specific teaching and
learning aspects.
23/10/2014 eLearning in diverse subject-matter contexts 3
(Baumgartner, 2003)
Do subject-matter contextual differences are indeed appearent within
the framework of eLearning?
What are the major characteristics of subject-matter contexts in order
to create more effective and efficient eLearning environments to
enhance quality in higher education?
23/10/2014 eLearning in diverse subject-matter contexts 4
PROBLEM
• Explore the eLearning practices of diverse subject-matter
contexts,
• Widen interdisciplinary practice of eLearning,
• Enhance the quality of eLearning offerings,
• Reduce gaps

What is being achieved with the help of this dissertation?
23/10/2014 eLearning in diverse subject-matter contexts 34
• A sophisticated eLearning practice is still not put into practice.
• No common understanding (technology vs. instructional strategy).
• Evidence-based practice is common
• eLearning paradox (dilemma between drives and drivers)
• Organizational & technical barriers
(Rolfe et al., 2008; Mayrberger, 2008)

What kind of suggestions could be raised?
23/10/2014 eLearning in diverse subject-matter contexts 36
• Diffusion of eLearning 2.0 and emerging technologies
• Development of interdisciplinary and transdsciplinary
collaboration and discourse

• Reveal new dimensions to communicate and diffuse eLearning
2.0 in higher education institutions.
• Investigate eLearning course development processes of diverse
subject-matter contexts in order to overcome the gaps in
development of eLearning 2.0 in higher education.

RECOMMENDATIONS
• Longitudunal evaluation of the extent of subject-matter context
diversity in order to adjust eLearning practices with best practice
cases (i.e. benchmarking).
• Disclose research over teaching phenomenon.
• Investigate the eLearning practices of emerging interdisciplinary
subject-matter contexts.
