From the evolution, it is bound to happen to us...
● University San Ignacio de Loyola, Peru● 3,500 simultaneous users → OK for MOOC
● Instituto Cultural Peruano – Norte Americano● 612,000 users registered → not really MOOC
● Académie d'Aix-Marseilles, France● 230 schools, differt portals→not really MOOC
● Ministry of Education – National exam – Peru● 9500 users taking an exam at the same time
● Not really MOOC (but technically MOOC)
Some real cases...
The MOOC's issues
● High number of simultaneous students in course Requires:● Ease of use (no need for support)● Automated processes (no need for coaching)● High efficiency (no need for extraordinary hardware)
Ease of use
● Chamilo LMS excels in● Fewer steps to get to content● Registering to platform → registering to course● Automated redirection to course
● Hide unused tools● Courses' introduction● Introduction per tool● Guided learning paths
Automated processes (1)
● Learning paths w/ prerequisites● Drives students in established path
● Exams (without free answer)● Automated evaluation● Immediate feedback
● Surveys
Automated processes (2)
● Gradebook● Build learning objects● Certificates
● Programmed announcements● Prepared links of interest● Course agenda
Other advantages of Chamilo
● Documents tools● Courses description
● Customizable presentation
● Light/Fast● Boostable
Efficiency & boosts
● 14MB per loaded page (average)● Reduce media sizes (png, jpg, videos)● Zip transfers (zlib)● Use APC or Zend OpCode
● Much more efficient with very high # of users
● Remove “online users” option● Or use optimization.html to put it in cache
● Optimize SQL queries (or remove them)● Use fixed values (PHP)
More efficiency boosts
● Remove code for documents total size● Use your/one language as default (hack into
end of global.inc.php)● 7KB weight (300KB first load → Expires,
Headers)● ExpiresByType image/jpg "access plus 1 day"● Header unset Set-Cookie● Header set Cache-Control "max-age=86400"
● MySQL indexes and/or tables in memory
Chamilo LMS ideal for MOOCs
● 1500 simultaneous users, with little optimization● 4GB RAM● 3 cores (3GHz)
