Teaching in the year(s) following graduation can be a valuable and enriching experience no matter what area you are ultimately looking to pursue a career in. The act of teaching allows you to gain a better understanding of how to communicate and confer information to others in the most effective way. This is a useful experience and skill to have in a workplace and beyond.
Many teaching fellowships and opportunities will also give you the chance to go abroad, where you can experience other languages, cultures, and education systems. Many of these programs will award their teaching fellows stipends and travel accommodations.
