We've spent most of the semester so far talking about what I identify as the single most defining aspect of pedagogy in a writing classroom: how we assess a student's writing, how we talk to them about that assessment, and what it means in terms of how a class is structured.
And I do believe that once you've worked through how you will assess students things like invention and revision--how you do them, why you do them, when you do them, how you count activities related to them--fall into place. But that also doesn't mean that there is only one way to do them.
For this in-class writing, talk about either a revision strategy or an invention strategy that you've used, thought about using, or experienced as a student that you felt was really useful. If you can, connect it to some of what you thought/wrote about for this week's readings on revision and invention.
Once you've posted your ideas, take some time to read the ideas of others. Be ready to have a conversation about the role of revision and invention play in composition.
