In Italy, the use of smartphones by students during classes has always been subjected to regulations. Schools tend to ban or discourage its use. Actually, its still seen by the majority of teachers as a pretext for distracting students. But the smartphone is a very powerful tool when used properly for teaching and learning. Hence, my challenge is to identify technology, paths, and facilities that could make feel teachers more confident about the potential of using smartphones in classes, in particular starting from the tools that Google has been developing for years for this device. The resolution of this problem would also bring countless benefits to schools, including significant savings.
