International audience Technological change is profoundly changing the way we are informed, as well as we communicate and learn. Through the Internet of Things (IoT) and connected devices, automation and intelligent support invest our daily life. Education plays a crucial role in improving our adaptive capacities, but its effectiveness and technological modernization are being questioned. To cope with these challenges, we question the possibilities of knowledge mediation in the context of the IoT, at the instrumental level, namely by linking the technological offer with the learning process. By characterizing this form of mediation, it appears that the construction of scientific knowledge and the way connected devices work participate in the same movement from observation of reality to abstraction. As a result, learning is based on the diversion and media implementation of the capacities of connected devices to make physical phenomena intelligible. However, while these new devices appear to be able to stimulate science learning, their use raises several questions about their effectiveness and the constraints they pose.
