Add to ORKGIn this paper I will present some findings of a teaching experiment on proof. Pupils were requested to produce conjectures in open geometric situations, to validate and, finally, to prove them. These activities took place in the microworld Cabri-Géomètre Our project was aimed to investigate the validity of the Cabri software as a mediator in the process discovering-conjecturing-proving. We found out that different dragging modalities are crucial for producing a shift from conjecturing to proving: these modalities can be analysed as the perceptive counterpart of the cognitive processes students use
