Moodle

Moodle is a learning management system that provides educators, and learners a single robust, secure, and integrated system to create personalized learning environments. Moodle is being used by a number of MNC's and Universities worldwide. Moodle was originally developed by Martin Dougiamas to help educators create online courses with a focus on interaction and collaborative construction of content, and it is in continual evolution. The first version of Moodle was released on 20 August 2002.

Moodle has adopted the following e-learning standards:

Sharable Content Object Reference Model (SCORM) is a collection of E-learning standards and specifications that define communications between client side content and a server side learning management system, as well as how externally authored content should be packaged in order to integrate with the LMS effectively. There are two versions: SCORM 1.2 and SCORM 2004. Moodle is SCORM 1.2 compliant, and passes all the tests in the ADL Conformance test suite 1.2.7 for SCORM 1.2. SCORM 2004 is not supported in Moodle, however Rustici Software have a Moodle plugin which can turn any Moodle site into a fully compliant SCORM 2004 LMS.
The AICC HACP standard for CMI was developed by the Aviation Industry Computer-Based Training Committee (AICC) and is used to call externally authored content and assessment packages. AICC content packages are supported in Moodle 2.1 and later versions.
IMS Common Cartridge packages can also be imported into Moodle. In addition, Moodle Book activities can be exported as IMS Content Packages.
Learning Tools Interoperability (LTI) is a standard way of integrating rich learning applications (often remotely hosted and provided through third-party services) with educational platforms. Moodle uses the External Tool activity to act as an 'LTI consumer' as standard, and will act as an 'LTI provider' using a plugin.
