Together, we will dive in to Claim, Evidence, Reasoning statements to support students to speak and write like scientists. Berkeley and Susan will cover the importance of starting with a phenomenon, and what CER statements can look like with examples of student work. They will also provide tools you can use right away to scaffold CER statements with your students!
