In the teachers' training schools of Reunion Island and Mayotte, we have been training primary preservice teachers in programming for the past three years. Most trainees have not learned programming before during their school and university curriculum. As a result, this subject is new to them and they find themselves in the situation of their own pupils. This is why we asked them, during their learning, to produce a "feelings" notebook in which they explain their successes, their failures and what it brings to them for understanding their own pupils. We make two type of studies of these documents: quantitative and qualitative. The analysis shows that if the whole group of trainees have globally identified the key aspects of a learning situation, it is not the case for each trainee.
