Sitting inside a conference venue in Dallas, Texas during the NSDC conference the following point was made (my notes):
"The power of a meta-analysis is that we can take a bunch of smaller studies and draw richer and more valid conclusions from them because the "n" is larger. When I was getting my PhD, my dissertation involved research using the perceptions and work of 45 teachers. I made determinations or found some trends "inconclusive" because I didn't have enough data. But when we combine research studies - we have a richer base to draw more accurate conclusions."
In this world of collaboration and creation via Web 2.0 tools - why can't we have doctoral dissertations (done on a small scale) become compiled as a meta-analysis in order to draw better conclusions? What are the roadblocks to this happening?
