The development of Information and Communication Technology (ICT) in society, and especially in the various fields of Economy, is mainly due to productivity gains it has allowed. In Education, it seems that ICT fail to actually grow. We can wonder whether this failure is because ICT in Education increases the burdens of teacher work. We show by the study of some cases, that the arrival of digital tablets seems to change the situation. One reason is that tablets will behave more and more like tutors and by this way relieve the teachers of a part of their workload.
