Grounded theory相关知识

The grounded theory可以分为三个流派。

1. 经典（Glaser）：Open coding-> 将数据打散分解，最好是一行一行进行编码，从数据中得到的概念（concepts），形成分类，这是今后形成的理论的基石。Selective coding->选择核心类属（core category）。The core category is the one category among all the categories generated during analysis that, in addition to other qualities, integrates the categories and is centrally relevant. Glaser provides some 11 criteria for choosing the core category – the most important of these criteria to us is the core category be the “most connected”. The core category reoccurs frequently in the data and comes to be seen as a stable pattern that is more and more related to other categories. Theoretical coding->将之前得到的概念和分类建立联系。 Open coding breaks the data open and generates categories as the building blocks for the theory. But a Grounded Theory is not a loose collection of categories. A Grounded Theory explains how people manage a problem through an integrated set of hypotheses.
2. 程序化（Strauss）：Open coding->将数据打散分解，命名原始代码。Axial coding->又称轴心编码，是寻找范畴之间以及范畴和概念之间的相关关系，然后发展出一个主轴范畴，并对这一主轴范畴进行深度分析(我理解是合并，分组为更抽象的类别）。selective coding->又称核心编码，指在已发现的概念范畴中经过系统分析选择一个“核心范畴”，从而将分析集中到那些与该核心范畴有关的代码、概念和范畴之间（选择核心类属）。
   3.建构型（Charmaz）：这里先不介绍。
