Master argumentative writing with our easy-to-follow steps and visual aid!

The ability to construct a strong argument is crucial across many academic disciplines and in everyday life. One effective framework for building persuasive arguments is the Claim, Evidence, Reasoning (CER) method. This article will guide you through understanding and utilizing this powerful tool, providing you with a clear understanding of each component and offering practical examples to strengthen your argumentative writing.

What is a Claim, Evidence, Reasoning (CER) Anchor Chart?

A CER anchor chart is a visual aid that summarizes the three key elements of a well-supported argument:

Claim: Your statement or opinion – what you're trying to prove.
Evidence: The factual support for your claim. This could include data, statistics, examples, quotes, or observations.
Reasoning: The explanation connecting your evidence to your claim. It shows why the evidence supports your claim.

Think of it as building a strong three-legged stool: Each leg (Claim, Evidence, Reasoning) is essential for stability. A missing or weak leg will cause the whole argument to collapse.

Understanding Each Component:

1. The Claim: Making Your Statement

Your claim is the central argument you're making. It's your thesis statement, the point you're trying to convince your audience to accept. A strong claim is:

Clear and concise: Easily understandable.
Specific: Avoids vague or overly broad statements.
Arguable: Presents a position that can be supported or challenged.

Example: Claim: Regular exercise significantly improves cardiovascular health.

2. The Evidence: Supporting Your Claim

Evidence is the factual information that supports your claim. This isn't just opinion; it's concrete data and information verifiable by others. Effective evidence is:

Relevant: Directly supports the claim.
Sufficient: Provides enough support to convince the reader.
Credible: Comes from trustworthy and reliable sources.

Example: Evidence: Studies have shown a consistent correlation between regular physical activity and lower rates of heart disease, stroke, and other cardiovascular illnesses. (Cite the study!)

3. The Reasoning: Connecting Evidence to Claim

Reasoning explains how the evidence supports your claim. It's the logical bridge between the two. Strong reasoning:

Clearly explains the connection: Avoids assumptions.
Uses logical reasoning: Inductive, deductive, or abductive.
Addresses potential counterarguments: Acknowledges opposing viewpoints.

Example: Reasoning: The studies demonstrating a correlation between regular exercise and lower rates of cardiovascular disease strongly suggest that physical activity plays a crucial role in maintaining cardiovascular health. The observed reduction in heart disease and stroke incidence is a direct result of improved circulatory function and reduced blood pressure, both benefits attributed to consistent exercise.

Creating Your CER Anchor Chart: A Step-by-Step Guide

Define Your Claim: Write your claim clearly and concisely at the top of your chart.
Gather Evidence: List the relevant evidence you'll use to support your claim. Include citations.
Explain Your Reasoning: For each piece of evidence, explain how it supports your claim. Use clear and concise language.
Visual Representation: Organize your information in a visually appealing and easy-to-understand format. Use different colors, boxes, or other visual cues to differentiate the three sections.

Examples of CER in Action:

Example 1: The impact of social media on teenage mental health.

Claim: Excessive social media use negatively impacts teenage mental health.
Evidence: Studies show a correlation between increased social media use and higher rates of anxiety and depression among teenagers. (Cite studies)
Reasoning: The constant exposure to curated online personas and the pressure to maintain a perfect online image can lead to feelings of inadequacy, anxiety, and low self-esteem, contributing to mental health issues. Furthermore, cyberbullying and online harassment are prevalent on social media platforms, further exacerbating these negative impacts.

Example 2: The effects of climate change on polar bears.

Claim: Climate change is significantly impacting polar bear populations.
Evidence: Data shows a decrease in Arctic sea ice extent, which is crucial for polar bear hunting and survival. (Cite data sources)
Reasoning: The reduction in sea ice directly impacts polar bears' ability to hunt seals, their primary food source. This food scarcity leads to malnutrition, reduced reproductive rates, and ultimately, a decline in polar bear populations.

Conclusion: Mastering the Art of Argumentation

Utilizing the Claim, Evidence, Reasoning (CER) method helps you build well-supported, persuasive arguments. By clearly stating your claim, providing solid evidence, and explaining the connection between the two, you can effectively communicate your ideas and convince your audience. Remember to use the CER anchor chart as a guide to structure your arguments and ensure they are both logical and compelling. Mastering CER enhances your analytical skills and strengthens your ability to present your ideas effectively in any context.
