Learning in citizen science is a complex procedure and only now we start to unravel and understand it. As an example, I would refer to : R. Edwards et. al: “Learning and developing science capital through citizen science”, in Hecker, S., Haklay, M., Bowser, A., Makuch, Z., Vogel, J. & Bonn, A. 2018. Citizen Science: Innovation in Open Science, Society and Policy. UCL Press, London. https://doi.org/10.14324 /111.9781787352339 and https://doi.org/10.14324
