case study and GT

I read a course PPT Case Study and Grounded Theory by chance. I guess it was created for a research methods in Engineering course CEE320 by Martin Fischer in 2004.

It mentioned David de Vaus and I found that David de Vaus in the book <<Research Design in Social Research>> (2001) outlines with great clarity a wide variety of issues of research methods and design, including testing theories, causation, data analysis, and the main considerations involved in using the different research designs covered. The "Teheory Building" and "Theory Testing" chapters will be very useful for Grounded Theory researchers.
