Several researchers studied the impact of collaboration between the learners, but few studies have been carried out on the impact of collaboration between teachers. In the previous work, the authors have studied the impact of the collaboration among the learners with a specific collaborative CEHL(K. Boussaha et al.,2015). In this work, the authors focused on the impact of collaboration on both teachers and learners. This paper aims to present a Computer-Supported Collaborative Coaching System called C.S. C.C.S. This system aims to create a virtual space based on the exchange of information and experiences between pre-experienced teachers to help new recruits or those who have difficulties and try to encourage, motivate, and provide them with needed experiences to help them escape isolation and use their solid information to guide their learners. To achieve the main task of our theme which is collaboration, we adopted the concept of groups. To demonstrate the effectiveness of the developed system an experiment was conducted. The results were highly satisfying and very encouraging.
