Interdisciplinary Projects – Moving From Transfer To Transformation In Learning, Anette Kolmos

Plenary Presentations and Doctoral Symposium

In the PBL communities, we have always argued that the deep learning in the projects would compensate for the lack of knowledge from taught courses by the students’ ability to transfer knowledge to new areas. Within the disciplinary discourses, this has proved to be valid as the transfer of learning works within the same language and disciplinary thinking and the projects share similarities. However, we have learned that in an interdisciplinary context, where students are to transform their experiences from a disciplinary to an interdisciplinary context, the students do experience difficulties in leading and managing their projects. This keynote will …
