Extraction, Processing and Visualization of Peer Assessment Data in Moodle

“…Due to its open source nature, it is possible to extend Moodle functionalities using external plug-ins or web services, as well as to modify the code and structure of the database of the LMS. Taking advantage of the extensibility features of Moodle, further additions to the Moodle Workshop module have already been proposed; for instance, [55,56] propose an extension of the assessment score calculation using Bayesian networks, which require code and database modifications and the design of an application program interface (API). This approach to the extension of the Moodle Workshop module is discussed in Section 2.…”

“…The second design approach entails the development of a Moodle local plug-in, generally written in PHP language, or the modification of the module files; this option can also be complemented with the use of an external application that processes the data from the plug-in or the modified module. Examples of these procedures are the extension of the functionality of the Moodle Workshop module in [55,56]. There are two important drawbacks of the implementation of local plug-ins and modification of Moodle modules.…”
