The C-E-R handout and poster are essential tools for enhancing students' understanding of scientific reasoning and argumentation in the classroom. C-E-R stands for Claim, Evidence, and Reasoning, a structured approach that encourages learners to articulate their thoughts clearly and logically.

The handout typically outlines the components of the C-E-R framework, explaining that a Claim is a statement or assertion that responds to a question or problem. Evidence comprises the data or information that supports the claim, drawn from reliable sources or empirical research. Finally, Reasoning connects the evidence to the claim, providing a logical explanation of why the evidence supports the assertion made.

The accompanying poster serves as a visual reference, highlighting the key elements and offering examples that can be readily referred to during lessons or discussions. Decorated with vibrant graphics and bullet points, the poster promotes engagement and aids memory retention, making it an effective resource for both teachers and students as they delve into scientific inquiry and critical thinking. Overall, the C-E-R framework fosters a deeper comprehension of scientific concepts while honing essential skills in argumentation and analysis.
