I am an architect / historian of science and technology with a prior course in physical sciences (University Paris7) during which I have already taught these disciplines to students in primary and secondary level (especially in science) Methodology I propose initially a work of observation of the behavior of the learner in front of various types of work then targeting the work on the points presenting difficulties by taking care to associate them with those more affluent. For fundamental level courses, I can assist and supervise homework and learning in all disciplines. In secondary, I can assist and supervise learning in scientific subjects (mathematics, physics, chemistry)
