Recent research has become increasingly interested in the concepts of education for sustainable development (ESD) and transformative learning (TL). However, even as ESD can be described as holistic and transformational education with the purpose to transform our society, only few studies have examined potential bridges between these two concepts. The article at hand gives an indication on this issue by studying the literature of ESD and TL. Strengthening the transformative aspect of ESD requires taking into account critical reflection, participation and social engagement, all of which all express key features of the new collaborative learning spaces (CLS). Subsequently, the potential of such CLS for the transformative mission of ESD are emphasized. In ESD as well as in CLS, the bridge between learning and action is crucial and a core element of social transformation. In order to clarify this, the new method of WeQ is described, aiming to better understand and develop CLS.
