The proposed solution is intended for virtual universities wishing to improve their distance learning platforms. These enhancements include the instructional content model, how to deliver courses to students, and how to evaluate students' knowledge. With this solution that improves the functionality of Moodle, virtual classes now include new features such as the transfer of heavy files, control of remote screens, video, audio, chat without degradation of the quality of service. The solution will be particularly useful for language teachers who have difficulty in assessing the speaking skills of their students. Indeed, the platform with its audio / video features, integrates a tool to assess the knowledge and improve the speaking skills of students. Teachers of technical subjects such as programming or computer networks will also be able to use this solution to improve the way they deliver courses, including making it easier for students to do practical work. On the technical side, the solution is based on the MSRP-RELAY, MSRP and Websocket protocols. It is therefore compatible with smartphones, tablets and computers. Tests were conducted with teachers of languages and STEM subjects to evaluate their students in direct synchronous encounters without necessarily going through multiple choice questions.
