Thanks for the reply, hj2012!
That is very helpful advice about taking time before applying to grad school--I had only ever considered it in terms of taking a break (like you said, avoiding burnout) but I had never considered how my application might be much stronger after graduation.
I have considered some Literature and Media Studies programs that allow some overlap with Gender Studies, because I'm pretty sure I could study within my research interests in any of these programs, but I thought a more specialized PhD may make me more "marketable." Although i know there are less positions available teaching in Gender Studies, there are also less people pursuing PhDs in it than Literature or Film. But I go back and forth on which is the better option all the time! My research interests are mainly in media/entertainment representations of gender, specifically horror film.
I had a feeling that teaching experience would be valuable in my growth as an individual and an educator, and I'm glad you can confirm that. A lot of people suggest that the teaching styles/goals for university are so different from high school that it might hinder my performance, but I never spoke to someone who had secondary teaching experience and then went for their PhD.
Thanks again for your help! What are you researching and writing about?
