Research key words – Significance
I find myself looking at the various strands of my research that I’m considering pursuing, and asking myself sternly, ‘Does this have significance? Is anyone going to benefit from my finding out more about this, as opposed to that, or maybe the other … ?’ Why do I want to pursue these various aspects? What might the outcomes tell us?
