Claim Evidence Reasoning or the CER Model

I was consulting in Texas, leading a workshop.  A Pasco representative was on hand, instructing how to use Pasco's probeware or sensors. The instructor wanted to add value, rather than just promote the equipment, knowing he would gain more customers with another presentation, this time one about the CER model, or 'Claim-Evidence-Reasoning.  I was immediately hooked.  As science teachers, we're always trying to get students to articulate their thoughts and ideas in succinct, cogent paragraphs, often unsuccessfully.  Here's a method. During the first week of Physics classes, I plan to introduce the BSCS CER model with these two CER examples, the first one is the example the Pasco rep used that hooked me on CER.  This slideshow has more details about the process.
