The Mystery of Aviation

open access: yesKonteksty Kultury, 2018
Suddenly the Mazowian landscape reared, it swerved askew from its logical angle and absolutely refused to straighten out no matter how much mental effort put into it doing so. The gray curtain of clouds was perforated. Blue sky, always present here at these altitudes, brushed against the pupils of my eyes.

From liquid learning to weaving learning: Negotiating meanings of Children's learning in family travel

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children's learning increasingly extends into everyday informal settings, but what counts as learning in these contexts remains insufficiently understood. Focusing on family travel as a mobile and socioculturally situated informal learning context, this study adopts a sociocultural perspective and uses liquid learning as a sensitising concept ...
