The purpose of this article is to highlight the ongoing work within the framework of a research project named Virtual3R. The primary objective of this project is to introduce an alternative method, based on Virtual Reality (Virtual3R platform), to reduce the reliance on live animals for training in biological engineering departments across France. The overarching goal in this regard is to provide learners with the basic technical procedures and gestures before engaging in real animal experimentation. The platform emphasizes its pedagogical contribution by providing a dynamic and collaborative learning environment for both teachers and learners. The technical framework supporting this perspective is based on an architectural design with different functional layers. This paper presents an overview of the platform's functional architecture, offering descriptions for each of its modules. Simultaneously, we present the results of the platform’s experimentation, which serve as evidence of the learners' overall satisfaction with the virtual platform. The findings support the platform's efficacy as a user-friendly and collaborative learning environment. These findings also validate the platform's pedagogical value, demonstrating its beneficial impact on knowledge acquisition and learners' active participation in the virtual environment.
