For distance learning you need a learning platform. One of the most used, best documented and well-fitting platform is MOODLE. Several methods exist to provide the MOODLE service.
The use of the platform needs some competences of teachers as well as of learners. The European Commission provides frameworks for both students and learners with a description of the digital competences that are expected with European Citizens (that are students in any case9 and as well with educators (teachers).
