Informal learning takes place not only in the workplace, but in all areas of life – even in environments that are rather formally structured. Little has been known, however, about informal learning among students at universities, outside of traditional courses. The article by Dr. Julian Decius, Janika Dannowsky, and Prof. Dr. Niclas Schaper just published in the journal Active Learning in Higher Education (IF= 4.765) presents a model and a measure to assess informal learning among students in higher education. The basis for the development was the Octagon Model of Informal Learning in the Workplace (Decius et al, 2019). The article is freely available here.
