I am doing a research with constructivist grounded theory, but don't know exactly how to use 'memoing' as a tool for data collection. Therefore, I need support.
I believe that Charmaz (2014) contains examples of memos in her book on constructivist grounded theory. Generally speaking, I recommend memoing any time something creates new thoughts about your data. That could be an insight into coding, an idea about modifying your interview guide, or thoughts about theoretical sampling.
