Points of contact between the ATD and the TDS: questions raised by the implementation of study and research paths

International audienceThe Anthropological Theory of the Didactic (ATD) aims to capture the complexity of real inquiries by using a type of instructional proposal called study and research path (SRP). Experimental research shows that certain notions of the Theory of Didactic Situations (TDS) appear specially adapted to analyse implementations of SRPs and point at some didactic phenomena related to the conditions needed for their implementation and management. We report this experience by first identifying some contact points between the ATD and the TDS and then describing the borrowings done. The analysis of the commonalities and specificities of both approaches helps to question the framework of the ATD and to point at some needed theoretical and methodological developments
