Interdisciplinary approach for the design of a learning environment
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how the didactical analysis of teaching and learning in workplace gives a framework to build the computational representation of knowledge. This analysis is shown within the context of the apprenticeship of concepts of anatomy and orthopaedic surgery.
Cabri-géomètre as a mediator in the process of transition to proofs in open geometric situations.
In 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 provi
