Reflection on the terms of "triangulation" and "grounded-theory"

Rebecca Hogue wrote on her blog about her understanding of constructivism, particularly, she explained two important terms in research methodology: "triangulation" and "grounded-theory". 

I didn't quite get it when she said "I think the image in my brain this week should be of my brain exploding into three pieces – the world-view piece, the learning theory piece, and the research piece." For me, with different views of the world (philosophic background), we defined methodologies broadly as quantitative or qualitative.

btw, her journey around the world without airplanes is pretty cool!
