Research Design I

• Context Moodle_at_GreekSchoolNetwork
• Ethnography Technology Ethnotechnology
• Principles
• It employs varying degrees of qualitative and
  quantitative descriptions of human social
  phenomena in connection to technology.
• A contexts properties cannot necessarily be
  accurately understood independently of each
  other.
• The ethnotechnologist is immersed with the
  context under investigation.
• She can be a member of her community searching
  for best practices.

Research Design II

• Ethnotechnology
• Discussions (Greek teachers associations, e-mint
  online community managers)
• Opinions (developers, Greek teachers, graphic
  designer)
• Observation notes from active participation in my
  Community of Practice (online courses)
• Quantitative Analysis from Moodle_at_GSN
• Grounded Theory
• Collaborative E-Learning Analytical Framework
