What do you mean by 'different pedagogy'?
U Aberdeen is one of Britain's seven 'ancient universities' and as such is very respected.
In any case, you already know that a doctoral path is much shorter in the UK. You are most likely to spend the first year learning research techniques, studying methodology, attending workshops, compiling bibliography lists and also beginning your research.
You will dedicate your 2nd and 3rd years primarily to doing research and writing up a dissertation.
I would perhaps do more research on their funding. Sure, many students are fully funded. Are all? If you are outside of the EU, you are not eligible for UK research council funding, particularly ESRC. Funding is not guaranteed in the UK - it is one thing to get into the programme, to get funding is the next issue. Also, full funding is normally for 3 years. I am not sure about the availability of additional funds if you stay for more than 3 years. By NO means am I discouraging , I am just saying that getting into Britain is not easy and funding is a problem, especially in the current economic climate.
If I were you, I'd contact their current students and ask lost of questions. Funding, placements (!!), research emphasis (they seem to be doing a lot of stuff on the Arctic), teaching opportunities in the department.
I wish you the very best with your decision! Scotland is awesome and if you choose to come here, I am sure you will enjoy it immensely. If you have any questions about student life in Scotland, feel free to PM me.
