E-learning is an emerging approach to education reflected in new learning techniques such as active and cooperative learning. Supporting communication technologies such as web-based tools, mobile devises and smart classroom used for interactive learning often come with side-effects that can be disruptive to the normal flow of the learning and the teaching processes. The use of technology van be hindered by the learning curve associated with the technology used during the class, the distraction from the initial goals of the course, the risk of mixing-up material related to the course, and concepts associated with the tools used in class, and finally, the time and effort overhead required from participants in preparing and using these tools. Therefore, it becomes crucial to continue benefiting from the advances in cooperative and communication tools, and in the same time minimizing the incurred overhead. In this paper, we propose a new classroom assessment tool: Active Class Probe (ACP) which can be used in an active and cooperative environment. ACP's main goal is designed such as to maintain focus on the initial course's learning goals, and minimize the external distraction incurred by its use in the classroom.
