The designedinterface allows the intelligent system to interact with the LMSand the learner, whose learning is continuously monitored andsupported by means of personalized recommendations andmessages. The system usability has been evaluated in the contextof a course about Computer Network Design. Results show thatthe designed interface is well integrated into Moodle andgenerates a non-intrusive user interface.
