How to Write a CER (Claim-Evidence-Reasoning)

Crafting a CER (Claim-Evidence-Reasoning) statement is a bit like baking a cake. You need the right ingredients, a clear recipe, and a sprinkle of creativity to make it truly stand out. Not sure what a CER is? It's a structured way to present arguments that makes your points clear and convincing. Perfect for essays, lab reports, or any document where you need to back up your claims. Let’s break it down together. One step at a time.

Start with a Strong Claim

Every great argument begins with a solid foundation: the claim. Think of the claim as your thesis or the main point you're trying to make. It's the statement that you want others to believe or understand, and it should be clear and specific. A strong claim leaves no room for ambiguity. It's a bold statement that you’re ready to back up with evidence.

For example, let’s say you’re writing a paper on climate change. A weak claim might be, "Climate change is bad." Sure, it's a start, but it’s vague and lacks the punch needed to grab attention. A stronger version could be, "Climate change is the most urgent environmental threat facing humanity today, requiring immediate and comprehensive action by global leaders."

Notice how this claim is more specific and sets the stage for the evidence you’ll provide later. Here’s a quick tip: If you can phrase your claim as a clear, decisive sentence, you’re on the right track.

Gathering the Right Evidence

Once you have your claim, it's time to back it up with evidence. Evidence is the data, facts, or information that supports your claim. Think of it as the proof that your claim is valid. Without strong evidence, even the most well-crafted claim can fall flat.

When gathering evidence, consider the following:

• Relevance: Make sure your evidence is directly related to your claim. It should clearly support your argument, not distract from it.
• Credibility: Use reliable sources. Academic journals, books, reputable news outlets, and official reports are great places to start.
• Variety: Incorporate different types of evidence, such as statistics, expert quotes, and real-world examples, to make your argument more robust.

Here's an example of evidence for our climate change claim:

"According to the Intergovernmental Panel on Climate Change (IPCC), global temperatures have increased by 1.2 degrees Celsius since the pre-industrial era, leading to unprecedented rates of glacial melting and sea level rise."

This evidence is specific, comes from a credible source, and directly supports the claim.

Connecting the Dots with Reasoning

Reasoning is where you explain how your evidence supports your claim. It’s the bridge that connects the two, showing your reader why the evidence matters and how it backs up your argument. Without clear reasoning, your audience might not see the connection between your claim and your evidence.

Think of reasoning as the "why" behind your argument. It answers questions like, "Why does this evidence matter?" and "How does it support the claim?" Here’s an example using our climate change scenario:

"The IPCC’s data indicates that the rapid increase in global temperatures leads to severe environmental consequences, such as rising sea levels that threaten coastal communities worldwide. This evidence underscores the urgency of addressing climate change as an immediate threat to human safety and survival."

Notice how this reasoning explains the significance of the evidence and directly ties it back to the claim. It's like drawing a line from Point A (your evidence) to Point B (your claim), ensuring your argument is cohesive and convincing.

Writing with Clarity and Precision

One of the biggest challenges in writing a CER is maintaining clarity and precision. It's easy to get lost in the details or to stray from your main point. To keep your writing sharp, follow these tips:

• Be concise: Avoid unnecessary words and focus on the essentials. Every sentence should serve a purpose.
• Stay focused: Keep your writing centered on your claim and evidence, resisting the temptation to go off on tangents.
• Edit ruthlessly: After writing your CER, go back and refine it. Look for areas where you can tighten your language or clarify your points.

For example, instead of saying, "The evidence presented by the IPCC, which is a reputable organization that studies climate change and related issues, shows a rise in global temperatures," you might say, "The IPCC’s evidence shows a rise in global temperatures." It's shorter, clearer, and just as informative.

Incorporating CER in Different Types of Writing

While CER is commonly used in scientific writing, its principles can apply to many forms of writing, from persuasive essays to business reports. Let’s look at how CER might fit into different contexts:

In an Essay

In a persuasive essay, your claim might be your thesis statement, with each paragraph providing evidence and reasoning to support it. For example, in an essay on renewable energy, your claim could be, "Renewable energy is the most viable solution to reduce carbon emissions." Each paragraph would then detail evidence supporting this claim, with reasoning that ties each point back to the main argument.

In a Lab Report

For a lab report, your claim might be your hypothesis or conclusion. Evidence would come from your data and observations, and reasoning would explain how these findings support your hypothesis. For instance, "The data indicates that the plant growth was significantly higher in the presence of sunlight, supporting the hypothesis that light is essential for photosynthesis."

In a Business Report

In a business report, your claim could be a recommendation or analysis. Evidence might include market research or financial data, while reasoning would connect these findings to your business objectives. For example, "Based on the current market trends, investing in digital marketing will likely increase our customer base by 15% over the next year."

No matter the context, the CER framework helps ensure your writing is clear, logical, and persuasive.

Common Mistakes and How to Avoid Them

Even with a solid understanding of CER, some common pitfalls can trip you up. Here’s how to steer clear of them:

• Vague Claims: Ensure your claim is specific and clear. Avoid generalizations that can weaken your argument.
• Weak Evidence: Use credible and relevant evidence to back up your claim. Avoid using evidence that doesn‚Äôt clearly support your point.
• Missing Reasoning: Don‚Äôt assume the connection between your evidence and claim is obvious. Explicitly state how your evidence supports your argument.

For instance, if your claim is about the benefits of exercise, don’t just say, "Studies show exercise is good." Instead, specify, "Research from the American Heart Association indicates that regular exercise reduces the risk of heart disease by 30%, highlighting its critical role in maintaining cardiovascular health."

Refining Your CER with Feedback

Feedback is a valuable tool for refining your CER. Whether it’s from peers, instructors, or colleagues, constructive criticism can help identify areas for improvement and strengthen your argument.

When seeking feedback, consider these tips:

• Be open-minded: Approach feedback with a willingness to learn and improve, rather than defensiveness.
• Ask specific questions: If possible, seek feedback on particular aspects of your writing, such as the clarity of your claim or the relevance of your evidence.
• Reflect on the feedback: Take time to consider how the feedback aligns with your goals and how you can incorporate it into your writing.

Here’s a practical example of incorporating feedback: A peer might suggest that your evidence could be more detailed. You could respond by adding a specific statistic or quote from a reputable source to bolster your argument.
