Honors Physics 2012 Objectives
In physics, SBG on August 10, 2011 at 8:01 AM
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.

CASTLE
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.
