EDIT: For the latest version of my objectives (including the ones for my regular classes), see the 2013 school year post, Physics Objectives 2013.
Here are my updated objectives for the year. For information on how I use them, read about conjunctive standards-based grading or check out my SBG cheat sheet. I limited myself to 5 objectives maximum per model this year.
The italicized parts are not strictly part of the objective. Instead, they are extra pieces of information to help flesh out what we’re looking to see students do. As always, feel free to steal/modify/etc.
I teach this class using Modeling Instruction (TM) (MI), and these objectives are based on my take on that curriculum. Where applicable (and where it varies from mine), I’ve added in the MI name for each model.

We’re planning to do some CASTLE (modeling version) work after the first 10 units. This is a change in our curriculum, so we haven’t completely finalized what we’re doing yet. I will update this page when we have set our objectives for the last couple months of the school year. So, watch this space. But not too closely. It won’t happen that quickly. Go do other fun things for a while.
EDIT: I ended up spending a couple of weeks on CASTLE with one of my honors classes, but ended up choosing not to assess on it, so I don’t have a good set of objectives for it.
