I taught middle school science for one year and it was a nightmare. I'm not sure if it was the grade level, the school, or the profession, but I vowed never to return to teaching. Now I'm working on a Phd in Microbiology, but I'm not sure a science career is for me either. I'm thinking of returning to the classroom after I get my PhD, but I'm worried that it will look bad that I only worked for one year. I'm also thinking about becoming certified to teach elementary instead of middle or high school. Has anyone returned to teaching or gotten a different type of certification? In interviews, should I be honest that I had a bad experience, but want to try again, or should I just say I wanted to pursue an advanced degree? Thanks!
