I am a novice researcher who is writing my dissertation. My topic is high school students' demotivation and their coping strategies in my country. Currently, I am thinking about using Straussian or Charmaz's GT to conduct my qualitative research. I have read some summarizing papers about these two approaches and found that Straussian's coding procedure is more rigorous but more detailed while that of Charmaz are more relaxed and flexible. For a novice researcher, which one should I use? I am afraid that I might not follow all of the principles of Straussian GT perfectly due to my lack of experience. But Charmaz's procedure might have so much freedom that I might add too much preconception to my analysis, which decrease its' value as GT. If any of you have any experience with possible difficulty in using these two approaches, please share them with me.
