| Sumario: | A case study of a real class is presented during which students analyze the situation of a container of water, located on the pan of abalance. They are asked if (and how) the scale reading will be altered by placing a floating wooden body in the water. The researchquestion is what role the experiment occupies in the social mechanism of progressivity. The analysis shows that the experiment canstrongly influence the discursive dynamics in the classroom. In the case analyzed, it operates as an element that fixes a part of thesemantic structure. The study enriches the understanding of interactions in the classroom and how they could be fostered; at the sametime, it provides information about how to generate the conditions for an experiment to be relevant from the point of view of learningconcepts and can be interpreted in depth by students. |
