An observation we have made recently is around students from perhaps city environments (who may not have had as much interaction with the outdoors as others) and international students is that they do not really appreciate what to expect from UK fieldwork.
Despite having a lot of guidance, background information and digital field trips, it does not really give them an appreciation of how cold it is at the top of the Peak District at the start of November. It can be a real shock for the students. To overcome this, we have tried to move away from all fieldwork involving charging around the countryside (with no toilets) to doing urban environmental science and urban physical geography. This has helped bridge the gap between having very limited field experience to full-on remote fieldwork with no facilities for 12 hours.
