Can challenge-based learning be effective online? A case study using experiential learning theory

The COVID-19 outbreak had a major effect on moving online learning activities, also traditionally experiential ones such as those designed upon Challenge-Based Learning (CBL) principles. This article explores the impacts produced on a Challenge-Based Innovation project work carried out in the context of a program developed by Politecnico di Milano and Politecnico di Torino.

Suggestions for an effective design of online CBI-like programs are offered
