Claim-Evidence-Reasoning (CER)
Have you ever had students respond, “I don’t know. It just did,” when asked to analyze and interpret their classroom lab results? We all want our students to “think like a scientist,” but often they fall short in connecting the dots between the lab results and the science concepts. Claim-Evidence-Reasoning or CER is a writing strategy that can develop a student’s analytical thinking and argumentative writing skills to turn that “I don’t know” into “aha, so that’s why we got those results in the lab.”
