Depending on the cases, this development sprung out spontaneously or due to the impulse of governing institutions, often in opposition to the classical model of teaching, that is essentially disciplinary in university and multidisciplinary in high-school. Consequently, this article was written as a testimony of the first conclusions that could be drawn from the experiment of a transdisciplinary bachelor program that opened in September 2012 in Aix-Marseille Universit&eacute;, in order to illustrate some of the merits and flaws of such an approach. The second part of the text is then dedicated to the description of two sets of workshops about the identity of academic disciplines, that were set up to develop collective tools for the elaboration of an interdisciplinary teaching that would really be fruitful to students. </span></span>From these works emerges the scheme of a circular process, where interdisciplinarity gives access to some forgotten fundaments of disciplines, which clarify the interdisciplinary dialog in return.</p> <p style="text-align:justify"><span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><strong>Keywords</strong> <strong>: </strong>interdisciplinarity, transdisciplinarity, discipline, teaching, university, high-school.</span></span></p>
