Recently had a chance to borrow a copy of Kathy Charmaz’s book for my paper and to dig deeper on her constructivist approach of GT.

Especially on coding, she says
“Grounded Theory coding consists of at least two main phases: 1_ an initial phase involving naming each word, line, or segment of data followed by 2) a focused , selective phase that uses the most significant or frequent initial codes to sort, synthesize, integrate, and organise large amount of data.”
