I graduated with my BS in physics in 2005 with a 3.75 GPA. Now I'm teaching high school physics and find myself wanting to get an advanced degree. I'd like to get a PhD eventually, but I'm not really sure how to get back into that world. I figured going through my upper-level textbooks and getting a strong score on the physics GRE would be a good place to start. I don't have any research experience since 2005, though, and the only classes I've taken recently were on teaching methods, so I'm not really sure who I would really want to write recommendations. Would I stand much of a chance as is or would I need to get some more relevant, more recent experience (take a class or do some research over the summer)? Would it be a better idea for me to earn a master's somewhere before applying to a PhD program? Thanks for the advice!
