个人感觉都柏林大学的M.Sc in Media Communications 和 利莫瑞克的 M.Soc.Sci. in Journalism and New Media are the best value for money, but I'd be happy to work with you on an alternative if either of those don't interest you.
I am aware that Trinity and Dublin City University offer some courses as well – though not ones with so good a reputation/feedback from past students as my two favourites. But they all have at least one course offering, which would make them worth looking into too. And then there is NUIG(New U of Ireland Galway) where the MA degree can also be applied towards your PhD in Arts & Humanities or just another master’s (MFA) programme——which will cost less than any other Irish university Master‘s.
NUI Galway(National Universities of Ireland)的MA is very broad-based,with modules like 'Introduction to Digital Communication','Digital Culture Studies'(the most recent module)等等...The lecturers are brilliant, knowledgeable and passionate about what they teach,and their feedback has been amazing over time.
