mainly faculties’ satisfaction toward the use of Sakai. • The survey was structured as follows: – 15 questions about users’ satisfaction toward: • Sakai • Customer service – 13 questions about: • Demographic • Skills/knowledge in online/blended courses • Attitudes toward online/blended courses • Assistant and training 22

50%, but significantly increasing through time. The percentages of courses per semester are significantly increasing through time. The percentage of instructors per semester did not significantly increase from spring 2011 to spring 2013. We have identified 8 colleges with percentages < 50% used of Sakai. 33 Server Data Conclusions
for the % of courses and instructors per year. The % of courses per semester might increase by 4%. The % of instructors per semester has a logistic distribution with carrying capacity fluctuating between 28% and 35%. 34
