Getting to know your students on a more personal level during a trip is a marvellous way to build a report with them that you will benefit from for a long time afterwards. Kids who have a personal connection with a teacher are a lot more participatory and motivated in class. Their behaviour in general improves, as they suddenly feel more connected to the teacher.
Travel makes one modest. We travel not to escape life but for life not to escape us. The use of travelling is to regulate imagination with reality and instead of thinking of how things may be, we see them how they are.
