## Standards for Matter & Interaction

Thanks to Frank Noschese over at Action-Reaction I didn’t have to start this list from scratch. He had a list of standards for the 2nd edition of Matter & Interaction by Chabay and Sherwood so all I needed to do was update it for the 3rd edition. I’m pretty excited about uses standards-based grading now that I have all my standards in hand. It seems much more manageable. For keeping track of it all I’ve decided to try ActiveGrade. I know some people use Excel, pen and paper, or Google Docs for keeping track of the standards but I wanted something the students could check on to see how they are doing and I wanted to involve the least amount of hassle on my part.

So here are the standards. There is also link to a Google Doc if you’d like to download these. Feel free to use them in your classes. All I ask in return is that you give back to the community and share, either by posting the changes you make or write about your experience somewhere online. I’m a big believer in open source and creative commons and all that so please give back to the online community.
