The paper offers a discussion about the concept of training from a psychological point of view. Training is a process that concerns a lifelong learning perspective, especially if referred to e-learning and on line activities. We present the Child Observation in School Context Workshop, an experience of e-training at Macerata University. We intend to stress the crucial relevance of self assessment in training processes that involve adults\u2019 participation. We describe the methodology used in the Workshop, according to the on line educational context. Besides peer discussion and negotiation, we pay attention to the final phase of the training process. In the instructional design it is significant to insert a phase in which teachers or trainers share with participants the criterions through which they will make the assessment. We show the differences, in terms of curricular results, between two editions of the same on line course: in the first one we did not share the criterions of assessment with participants, on the contrary in the second edition we dedicated a special moment to this activity. We demonstrate the importance to plan a moment in which participants are requested to evaluate their involvement both in terms of process and outcomes
