Dynamic synchronization of learning contents of distributed learning management systems over band limited network — Contents sharing between distributed Moodle 2.0 series

Sharing learning contents over distributed learning management systems (LMSs) is an important issue in order to reduce the burden for building well-designed contents. As a lecturer, regular updates of contents for on-going courses are really important because contents should reflect the learners' attributes as well as for corrections and additions of contents. Although this kind of dynamics is preferred for actual situation, differential updates of contents suitable for distributed LMSs are not implemented on popular open source LMS, Moodle. This paper introduces the dynamic synchronization between distributed Moodle systems and reports the synchronization results between Moodle 2.0 series systems. The proposed method has been implemented on Moodle for versions 2.0 series up to 2.3 as the extension of the previously proposed method developed for Moodle 1.9.
