Annotating 

To CAPTURE is to notice or identify something that the writer did.

To CREATE is to have an original thought about that choice, a question about that choice, or an idea about that choice. 

Capture: The author uses a lot of informal language in this paragraph.

Create: The informal diction makes a very academic subject, that would usually intimidate me, seem easier to understand. 

In this podcast Kwik talks about a method of annotating in which you utilize the left side of the page to CAPTURE and the right side of the page to CREATE.
