In class on 2/22 we discussed the skills of using text to think about and using a text to think with. When using to think about, you illustrate using examples and contextualize using historical/statistical information. When using research to think with, you can authorize, borrow, and extend information.
In looking at applying this to my unit 3 project, I would say the most useful tool here would be extending. Extending your research and putting your own spin on it seems like the best way to create your own effective research piece. While I also borrowed and authorized from other authors, I believe extending my academic source was most effective in creating my own piece.
