Using CER to Explain Environmental Decisions

Miacademy & MiaPrep Learning Channel

This video introduces students to the Claim, Evidence, Reasoning (CER) framework, a critical tool for constructing scientific arguments and communicating environmental decisions effectively. Building upon a previous lesson about a cost-benefit analysis for a forest owner named Mr. Carter, the video demonstrates how to transition from making a decision to explaining it persuasively. It breaks down each component of the acronym: the Claim as the decision statement, Evidence as the supporting data (quantitative or qualitative), and Reasoning as the logical bridge connecting the two. The video explores key themes of scientific communication, critical thinking, and environmental stewardship. It emphasizes that CER is not just for persuasion but also for reflection, ensuring that decisions align with stated goals and are supported by strong evidence. The content specifically addresses the challenge of distinguishing between simply listing facts and providing the logical reasoning that explains why those facts matter, using the metaphor of a bridge to visualize this connection. For educators, this video serves as an excellent scaffold for teaching scientific writing and argumentation, specifically within the Next Generation Science Standards (NGSS) practice of engaging in argument from evidence. It provides concrete examples and built-in pause points for students to practice writing their own CER statements based on a provided scenario. This resource helps students move beyond simple "yes/no" answers to developing sophisticated, evidence-based arguments applicable to environmental science and beyond.
