The construction of physics knowledge in the classroom from different perspectives: The classroom as a community and the students as individuals
This chapter contributes to research studies on physics classrooms from a methodological perspective. It is focused on the reconstructions of the knowledge that is involved in the classroom during teaching sequences devoted to a specific topic of physics at secondary school level. These reconstructions, mainly done from video recordings of the classroom during teaching sequences, can be carried out from different perspectives, that of one participant of the class, the teacher or a student, or that of the class as a group. Our methodological approach is based on several theoretical positions concerning knowledge, teaching and learning.
