This work was carried out in actual classroom condition with thirty-eight fourth level students of a secondary school. Their written solution of a problem on kinematics was examined. The analysis was based on the conceptual fields theory by Vergnaud (1982, 1990, 1996, 1998) and on the mental models theory by Johnson-Laird (1983, 1990). Such analysis was conducted to interpret students' difficulties in building mental models during problem solving. In conditions where students could have, or not at all, the needed abilities for immediate solving the problem, a better comprehension of the role of the "scheme" construct in physics situations was shown to be fruitful to understand students' representations during problems solving. The results suggest that motion description is not a trivial job. However, in standard situations an important group of students has acquired a good skill with main algorithms to make scientific descriptions. But in new situations, cognitive variability was shown.
