“…CVL@b-LMS is responsible for the management of learning process through a set of sub-systems: 3D environment for practical work, supervision & control system [21], evaluation system and tele-collaboration system. In this paper, we concentrate on CVL@b-LMS and more precisely on the tele-Collaboration system (LMS-SCA).…”

“…Regarding tutors, dynamic or evolving situations of teaching/learning require from them a certain number of specific activities to build cognitive skills. The use of ICT in CVL@B offers the tutor means of supervising, controlling Tele-PW activities, and giving effective feedbacks [21]. The tele-cooperative mode, in CVL@B, is provided by individual learners' workspaces who will act independently.…”

“…Many scientific productions present the socioconstructivist theories that the learning process is a collaborative and constructive process with directions how to overcome the eventual lack of support of those features in virtual and remote labs as deploying those laboratories into education management systems, supporting the labs to be operated by multiple users at one time, embedding the labs into virtual, etc. [20] In our previous works, we implemented CVL@b: an agent-based platform of Virtual Laboratory [21]. This platform is a distributed digital environment that contains a space for editing documents describing Tele-PW, an electronic library and a space where the experiment is performed.…”

This work is part of a learning environment that has virtual laboratories that are designed for distant practical work (Tele-PW). In these environments, Tele-PW is performed in two modes: individual and/or collaborative. In this paper, we are concentrating on the tele-collaborative distant practical work model. The work, presented in this paper, proposes an artificial agent called Synchronizer Coordinator Agent (SCA) to synchronize and coordinate the activities of a cognitive process in order to build and maintain a shared conception of a distant practical work between a set of learners. This agent provides certain features such as managing groups of learners, coordinating tasks, shared workspace among members of the Working Group. It is also responsible for the synchronization of workspace agents when they want to manipulate shared virtual objects simultaneously. We have chosen Petri nets to illustrate the principle of granting access to shared objects in the case of simultaneous requests. Experimental results show the effectiveness, of the artificial agent within any tele-collaborative/tele-cooperative learning situation. Several situations describe the geographical/time dispersion of learners and tutors in our system are considered during the system design phase.

“…Currently, researches focus on the design and development of advanced VLs (Carlos et al 2019;El Kharki et al 2020;Wahyono et al 2020). However, the majority of learners are facing difficulties in finding suitable VLs that ensure typical learner interactions and remote collaborations during COVID-19 (Mechta et al 2012;Wästberg et al 2019) in the field of experimental sciences. Thus, a remote collaboration between learners is essential to successful practical work.…”

This paper introduces a virtual laboratory that aims to support the quick development and easy assimilation of practical works by learners and exchange documents between them via a shared virtual space. The proposed laboratory, named 3DVL@ES (web-based 3D virtual laboratory in experimental science), defines an agile design process to automatically generate 3D pedagogical web applications and provide very appreciable interactivity, flexibility, and collaboration for practical works development. Also, 3DVL@ES includes the specification of learners' interactions and collaborations on a unified application model to assist and automate the creation of new 3D interfaces related to practical work in experimental sciences. 3DVL@ES has been applied in a real case study of Daniel's Battery. The obtained results have been compared with other virtual laboratories to show the usefulness of 3DVL@ES. Experimental results show that 3DVL@ES laboratory easily achieves complex practical works with the integration of cooperation and collaboration aspects.
