In the two year college environment, it can be difficult to access the full text version of research papers. Typically, after a PUBMED search , students can be discouraged when they are faced with a journal paywall. However, unless the paper is very recent ( within the last 6 months) the vast majority of papers are available through PMC ( the free access version of PUBMED) . So just "google" NCBI PMC and that will take you to the front door !
For very recent papers , one can request a pdf from the author. In many journals , this is expedited by a simple online request.
