Teaching physics in a difficult environment: co-construction of the reference in double class and entire class
Abstract
International audience To better understand ordinary teaching practices, this paper compares the way a physics teacher co-constructed the reference with her students working with a half class group and with the whole class group. We observed that when the teacher works in a half class group, she succeeds conditionally in building an effective partnership with students for elaborating knowledge. We also observed that the strategies she uses are less efficient in the whole class, collaboration being more uncertain, and this leads the teacher to get an “overhanging” posture.
