I am starting my PhD this Fall in Math Education. I would like to either teach math at a university or work in a curriculum and instruction department doing research and teaching for a university. For this reason, I have included many graduate level math classes in my program of study along with the required curriculum and instruction courses.
Obviously, when I get done with my PhD I would like to have as good of prospects as possible to find a job at a university. I want to research something I'm passionate about, but I also want ideas on hot topics in math education research currently. If my dissertation research aligns with what some others in the field are researching then this may increase my chances of future employment. Currently I'm interested in studying the detrimental effects of using a calculator on mathematical thinking. I don't know how interesting this is to others in my field so I am looking for some suggestions. What are some hot topics in math education research currently?
