I have travelled to Perth, Australia and Oxford as part of my studies as well as for fun. Furthermore I have visited many cities in Europe, e.g. Paris, Porto, Lisboa, Barcelona, Prague, London, Edinborough, Brussels, Ulm, Hamburg.
Love to do short visits to breathe in the culture, do some sightseeing. Unfortunately I do not have time on my hands for longer trips... Maybe in the future!
One of my favorite quotes is from Benjamin Franklin:
Tell me and I forget, Teach me and I remember, involve me and I will learn.
In my opinion, the best way to teach and learn is in an active way. Whether that is by being part of the organization or the way teachers present their lessons does not matter.
By travelling abroad you get to learn about different cultures and organisations, different styles of education. By taking these experiences back to your home country, you can implement the good things to improve your own system.
