The study assesses the possible impact of Learning Objects (LOs) and Mobile Computing in the field of education. The issue is dealt with according to two perspectives. The first considers LOs as a product whose creation is entrusted to the students. This leads into the realm of constructionist learning and to using technologies within perspective of ”not to learn from them but to learn with them” guarantees the effectiveness of integrating them in education. To put this approach into practice effectively, teachers are required to learn to manage a new form of education. This is the focus of the first part of our study. The second part examines the idea of using LOs as pre-constructed objects and as resources that promote significant learning.
