Is There ‘ONE way’ of Learning? A Data-driven Approach

Pierre Dillenbourg, Barbara Bruno, Jauwairia Nasir

Intelligent Tutoring Systems (ITS) are required to intervene in a learning activity while it is unfolding, to support the learner. To do so, they often rely on performance of a learner, as an approximation for engagement in the learning process. However, i ...

Imagining with and in Space: Structural support as a cognitive device in architectural education

Dieter Dietz, Julien Lafontaine Carboni, Darío Negueruela Del Castillo, Aurélie Dupuis

In this paper, we will argue that the structure of the spatio-temporal pedagogical set-up and the elaboration of an evolutionary support for operations of cognition and imagination are powerful in transforming learning cultures. We develop this argument in ...
