Abstract
<strong>In a difficult economic context in the world in general and in the countries of sub-Saharan Africa in particular where we seek to make maximum return on investments; this paper draws on part of cloud computing technologies to offer traditional universities the possibility of carrying out practical work via the cloud without using either physical IT equipment or physical practical rooms; and on the other hand, on videoconferencing technologies to ensure synchronous monitoring of this practical work. Thus, a cloud-based laboratory model for STEM disciplines is proposed in [1]. In the implementation of the model, we proposed the solution based on practical work in the field of IT. This paper document is an extension of [1] and offers a videoconferencing solution for monitoring practical work applied on the cloud for collaborative work between the teacher and the learners. In this new model, practical work is done using virtual machines from the cloud, but real-time monitoring is provided by a videoconferencing system, the following functionalities of which have been added: screen sharing, file sharing and virtual classroom recording. </strong>
Highlights
The global context of higher education is marked by a considerable increase in the number of students in sub-Saharan countries and international student flows
To access these instances and videoconferencing resources, we have developed a web platform to allow students to carry out practical work and teachers to prepare tutorials which they can monitor and supervise
We first started with a cloud-based lab laboratory model and integrated a videoconferencing solution for synchronous monitoring of these labs
Summary
The global context of higher education is marked by a considerable increase in the number of students in sub-Saharan countries and international student flows. Science education is above all, manipulation, experimentation and practical work Universities find it difficult to keep up with the pace of supply and maintenance of existing infrastructure, given the growing number of students each year and. Faced with the difficulties of supplying infrastructures to universities in developing countries, Cloud computing becomes an ideal solution for optimizing the resources of higher education and research [2]. To carry out our work, the rest of the paper will be organized as follows: In section 2, we present the state of the art of distance education and cloud computing as well as the research results in relationship with these two areas.
