Final answer:
Change discourse encompasses various ways of talking about and approaching change.
Step-by-step explanation:
Change discourse refers to the language and communication strategies used to discuss and enact change. It encompasses the various ways in which people talk about and approach change. In this context, competence talk, exception talk, and context-changing talk are all part of change discourse.
Strategizing, on the other hand, is not considered a part of change discourse. Strategizing refers to the process of planning and developing strategies to achieve specific goals or outcomes. While strategizing can be informed and influenced by change discourse, it is not inherently a part of it.
