“…Once again, we found a variety of ways and places in which researchers carried out these observations. One of the most common places to carry out observations was the classroom, as evidenced by a range of studies which followed this approach (Cheng Pui-Wah et al, 2015;Fekonja-Peklaj and Marjanovič-Umek, 2015;McEvilly, 2015;Northard et al, 2015;Reunamo et al, 2015;Wu, 2015), while only in one study the observations were carried out in outdoor spaces (Merewether, 2015) and another where the researchers observed children at home (Wernet and Nurnberger-Haag, 2015). Two studies combined observations with other methods, such as interviews (Wu, 2015) and child evaluations (Reunamo et al, 2015), although in the latter, there was no explanation about the way in which the evaluation took place.…”
