This paper discusses a solution for digital universities to extend the functionality of their e-learning platforms to improve, not only their delivery model of instructional content, but also their way of assessing the knowledge of the students. Indeed, this paper proposes a solution for the platform of Moodle, allowing to create virtual classes, integrating the sharing and the control of screens, the transfer of files independently of their type and their size, the video, the audio, chat, different actors. This solution integrates an audio and video knowledge assessment tool for language lesson modules and enables learners to learn to communicate. Our solution is built around MSRP and WebSocket protocols, is used directly with current browsers as well as computers, smartphones and tablets. Our solution has allowed, among other things, language teachers and STEM to perform work online and face-to-face as it should without necessarily resorting to the MCQ or be obliged to modify the tests to take into account the difficulties related to the evaluation of programming and networking lessons.
