hand, and to estimate interconnected/overlapping
criteria, on the other hand.
This analysis has shown that both VLE tech-
nological evaluation methods analyzed have a
number of limitations: (1) the method developed

in New Zealand's Open Source LMS project
(2004) practically does not examine the adaptation
capability criteria, and (2) the method proposed
by Graf & List (2005) insufficiently explores the
general technological quality criteria.
