For both frontend and backend, we use Moodle (modular object-oriented dynamic learning environment), a PHP learning management software that has been developed by an open-source community since 2002.
Each course comes with its own online folder that contains course information, attendance, calendar, study materials, links as well as quizzes and evaluation forms. It is an ecosystem serving to a complete overview of the course, its content and history.
Students have access to their courses via browser or through the mobile app (read more in the blogpost).
For online education, we use BigBlueButton. It is designed especially for distance learning. The browser-based system uses pureHTML5 technology, runs on every operating system and mobile device.
Virtual classroom access is secured by Moodle, so every logged in user having their active online course will be able to join the session directly from Moodle via an existing username and password.
