Claim: My students understand CER (Claim, Evidence, & Reasoning). Evidence: I posted a video to High Tech High’s learning videos website of my students verbalizing their claims, evidence, and reasoning on a cube that was missing a side. Students were asked to use the clues from the other five sides of the cube to infer the sixth side. I also posted a sample of their written CERs and a conclusion to a lab on the metabolism of yeast that students wrote using CER after they practiced writing CERs about cubes with missing sides. Reasoning: My students understand CER as evidenced by their written CERs in which my students wrote a claim that was an answer to a laboratory question in the form of a clear and concise statement. The students were able to write an explanation for their claim that linked with their data. Therefore my students were able to provide sound reasoning.
