The objective of this article is to model and implement a learner Supervision and Control Tool during a remote learning session of practical work. This tool will be integrated in our Collaborative Virtual L@boratory. It serves the users (learners, teachers, tutors) of our virtual laboratory during the assistance and evaluation process. It allows the tutors to be aware of the work-progress status and makes a model for the average learner based on his/her actions and interactions. The functionalities supported by this system are: synchronous supervision (tutors and learners are connected simultaneously), asynchronous supervision (using the activities’ history) and guiding the learners.

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.

The objective of this article is to model and implement a learner supervision system during a remote session of practical works (PW). This system will serve the users (learners, teachers, tutors) of our virtual laboratory during the assistance and evaluation process. It also makes it possible for the teachers to be aware of the progress status of the work. Another characteristic is added, it is a question of designing a model for the average learner based on his/her actions and reactions. The functionalities supported by this system are: the supervision in real-time (teachers and learners are connected simultaneously), supervision in differed time (using the activities' history) and guiding the learners.
