A Flipped Classroom experience: the lateral instability phenomenon

For a teacher, to inspire creativity and innovation is definitely a big challenge. One of the best ways that a teacher can use to get this result, it is an instructional strategy based on active learning such as the “Flipped Classroom”. This paper describes a small Flipped Classroom experience developed at the school of Architecture of Politecnico di Milano and subsequently at the Université catholique de Louvain. To develop this activity the students of architecture are invited to reflect on an important and difficult problem, both for the qualitative explanation of the phenomena and for the mathematical formulation: the lateral instability phenomenon. In general, stu-dents of architecture do not possess the knowledge for dealing with this phenomenon. This situation stimulates the reflection and the collaboration among students
