Claim-Evidence-Reasoning (CER)
Claim-Evidence-Reasoning (CER) is a discussion structure used by scientists and engineers to engage in collaborative discussions with other scientists and engineers. The CER process enables scientists and engineers to provide well-organized, evidence-based explanations that include logical reasoning. While both scientists and engineers use the CER structure, they use it for different purposes. Scientists tend to focus on asking questions and analyzing patterns while engineers tend to focus on solving problems.

(c) Claim
The claim sets the tone for the rest of the writing. It is the argument, the stance, or the main idea of the writing that is to follow.
(E) Evidence
Evidence is the proof, or support that you have for your claim. Evidence is where you present the data and logic you used to arrive at your claim.
(R) Reasoning
Reasoning is the thinking behind the evidence that led to the claim. It should explain the evidence and then connect it to the claim.
