Technical reference and laboratory class of physical sciences in french technical school ("lycee professionnel").
SCACHE Daniel
Our aim is to conceive a method to teach physical sciences in technical schools (lycees professionnels). from observations made in classes, during examinations, in the professions related to physics, we have deduced that this subject-matter is not felt as necessary by the students : they do not see the sense of it nor its interest in a short or long term. starting from investigations, assessments and "technological building-ups", we show that the technological object, which is a structured and functionnal object, is apt to allow students to handle new "intellectual tools". resorting to a hypothetico-constructive method in the course of learning is better justified than an inductive method. the technical object andhypothetico-constructive method are dealt with by the test-class technique in which the "situation problem" set by the technical object in the course of fonctioning is gradually solved by experiments which the students carry out to probate their initial hypothesis.
