RJA #5a: Reference Articles

I am having the worst luck with the resource article stuff. I cannot find anything that is relevant to my research. I have tried so many of the reference works listed on the assignment (I went down the list for days) and nothing will come up. I tried different search strings on each site and either it says no results or it will give me things for my education, like associate/bachelor degree programs. I even tried to access some things off the library website and I am not having any luck. I used the search strings of RJ 4 listed: +importance +early +childhood +education+benefits +early +childhood +education -teacher+importance +benefits +early +childhood +education -teacher+importance +benefits +early +childhood +education -teacher +student. If anyone has any good ideas please share them!!
