While OneSearch is a good place to begin exploring for your research, specialized Databases offer more focused ways to conduct higher-level research.
Under the Databases menu on the Libraries home page, you can sort the big list by Subject. A good place to start for EDPS is the Educational Foundations list, found here: https://library.hunter.cuny.edu/databases/subject/38
Below are the ones I recommend starting with for your research, but feel free to explore others.
