I studied abroad in Madrid with the IES program the summer of 2002.  I am currently teaching a bilingual pre-k in NYC and have found that my Spanish is incredibly useful.  Not only does it help me interact with the children and their parents successfully, but I think that studying a language and being in Madrid has made me more sensitive to the difficulties my students and their families face in learning a new language and struggling to understand.  My only regret is that I wasn't able to study abroad for a full semester!
