This research is part of a project led by Hiprest, a collective that deals with the language teaching education. The research programme is based on the theories of the activity to analyze the Primary teacher training students’/novice teachers’ experience during their Practicum. The project has a double objective: promoting future teachers’ training as long as researching on the process resulting from the proposed training device. Following an innovative training-researching methodology based on video-formation, three classroom video-recordings have been analyzed together with a selfconfrontation interview between each of the students and a researcher. In those interviews the future teachers observe and analyze their own teaching actions from the “outside”. That provokes the students to figure out aspects, attitudes and techniques that could allow them to improve their activity in similar teaching situations. The research evidences training phenomena such as analytic immersion and virtual typification that characterize the training process. Resulting knowledge will allow definition of new training contents directed to specifically improve teaching practice and novice teachers’ development.
