The school is divided into different areas: one for nursery, another for primary grades, and another third for the secondary-year students. Within each grade, there are four different classes (from A to D). Hence, for the purpose of this research investigation, I will concentrate in one classroom only: fifth "D" of primary school.This classroom is long and wide. It has large double windows on one side, and the exit door on the other side, in a corner. As one enters, one finds two blackboards that cover the whole wall on the right; a dais as long as the board, where the teacher's table and chair are situated and, where the blackboard finishes, there is a door that connects to the next classroom. The rest of the classroom has individual tables and chairs for the children, so it can be organized in different ways. This is an important detail for our investigation. On the wall that is to the right of the entrance door, there are hangers for the children's coats.
