I'm just trying to play devil's advocate here:
Isn't it expected that through an undergraduate education, most students have been introduced to the scientific method and basic abilities to research? Just as there's prerequisites to certain classes in terms of knowledge, there's inferred (I would think) prerequisites to some of the upper division classes with writing components that you understand how to read research articles, decide what's relevant information from an academic perspective, and write about it.
There may be a clear-cut definition about what the VMCAS is looking for in terms of "research," but I personally think my semester nutritional therapy project on Hereditary Hemochromatosis, although substantial, pales in comparison to legitimate research in a laboratory. I researched a bunch of papers about the disease, learned about the best treatments, and put together a comprehensive report. Whoop dee doo, how does that show my abilities as a researcher compared to the PCR, immunohistochemistry, western blotting, genotyping, 3D cell culturing, immunocytochemistry, etc, etc, and analyzing data that's targeted to a specific hypothesis and carried out in an actual lab?
I know not everyone has the opportunity to work in a lab, but I just have a hard time seeing schoolwork as research.
Either way, whatever paints you in the best light is the way to go
, that's the goal.
