To characterize their conceptions, we constructed a questionnaire with numerous choices (QCM) regrouping 16 questions. For every question, the student had to encircle the number which corresponds to its choice (1: In disagreement; 2: I do not know or 3: In agreement) besides pointing out the reasons of his choice. Questions were formulated around 4 topics: (1) the objectives of science and its development limits, (2) the role of measure, experimentation and theory in science, (3) the evolution of science: continuity and breakthrough, and (4) logico-mathematical reasoning in sciences. For example, regarding measure, experimentation and theory, their conceptions oscillate between several opposed tendencies, as realism and empiricism. Also, according to the majority, the development of science is uninterrupted and corresponds to an improvement of theories and of laws developed across different epochs and that theory must follow experience.
