As mentioned in the video, Google Scholar is a specialized version of Google that only searches peer-reviewed sources, patents and case law.
Knowing this, and knowing how comfortable we are with Google, I would not start my research with Google Scholar. It tends to do what Google normally does: throw up far too many results to be useful. I only really use Scholar to find a source I know exists, like from a bibliography.
If you go to Academic Search Complete first, or, use another library database, Scholar will know you're an R-MC student, and will let you know if we have access to the articles you're searching for.
