From “So What…?” to “Aha!”: Guiding Students to Stronger Data Conclusions

Why Students Struggle With Data Conclusions

If you’ve ever asked students, “So…what can we say from these data?” you’ve likely heard responses such as:

“The line goes up.”
“It increased a lot.”
“The dots are all over the place.”

These observations aren’t wrong—but they’re not conclusions. They’re simply descriptions of what students see on the surface.

Helping students move from “So what…?” to “Aha!” requires intentional scaffolds, opportunities to explore, and the right kinds of questions. This month’s Strategy Share Out workshop—From “So What?” to “Aha!”: Guiding Students to Stronger Data Conclusions—focused on exactly that.

This post extends those strategies with new examples, classroom-ready moves, and tools you can use tomorrow.

Why Data Conclusions Break Down

We often hear from teachers and see students struggle with forming strong data-based conclusions because they lack:

1. Experience Interpreting Data, Not Just Reading It

Students may know how to label axes or identify components of a dataset, but data interpretation requires connecting observed patterns to other ideas or insights that relate to the broader phenomena or system being investigated. This is higher order thinking and it takes time…but typically falls at the end of a learning sequence and thus can get squeezed for time.

2. Language for Making Nuanced Claims

In an attempt to support students along their learning progression, we often provide them sentence starters, comparison phrases, and domain-specific vocabulary to express insights clearly. This is great! And, if the complexity of those supports do not progress or the scaffolds are not removed over time then they become a crutch that can limit students’ abilities rather than support them.

3. Opportunities to Play Before They Conclude

Students (ok to be fair, all humans) like to jump to conclusions. And often our learning activities ask students to first make a claim, typically before they have had space to explore the data. Exploratory “muck about” time helps students notice more, question more, and conclude more effectively. (Curious what “muck about” is all about? Check out last week’s blog post “Increase Sensemaking by Leaning into Playing with Data”).

So let’s explore some strategies that can help students overcome these three common struggle points. Here are 6 ideas to try before winter break:

Strategy 1: Help Students “Surf the Data” Before They Sink Into Conclusions

Students need time to notice, think, wonder, and interrogate the data before they’re asked to summarize or explain it. Think of this as “warming up the brain.”

Try the following prompts:

Noticing Prompts: Engage with the Content

What is the context of the data?
What are the parts of the map?
How are colors being used?
What kind of map is being used?
What kinds of data are being used?

Thinking Prompts: Start to Analyze

What are these data visualizations showing you about the data?
How can you describe how the variables change?
What are the patterns in the data?

Wondering Prompts: Head towards Interpret

What could the patterns mean?
How could those patterns occur?
What do the patterns mean to you?
How might the patterns relate to
other things you know?

Interrogating Prompts: Pause to Dig Deeper into the Data

What choices did the graph creator make?
What might be misleading?
How does scale affect interpretation?

Giving students structured time for these various steps primes them for stronger conclusions by helping them see more than just increasing or decreasing trends.

Strategy 2: Use the CER Framework—With a Data-First Twist

The Claim-Evidence-Reasoning (CER) framework remains one of the most powerful tools for teaching to communicate their conclusions or evidence-based arguments after they have done their sensemaking. But many students still struggle when the evidence is in graph form instead of text.

Two quick steps in addition to what we discussed in this month’s Strategy Share Out are to have students:

Write evidence statements directly from the graph, using quantitative details (“increased by 40%,” “cluster between 12–14,” “peaks at…”).
Provide sentence frames for reasoning (e.g., “This suggests that…,” “One possible explanation is…”).

Check out our new digital resource specifically designed to help students strengthen their CERs by breaking down the differences in how we use the structure if we are arguing from evidence or constructing an explanation…similar but different things:👉 CER Arguing from Evidence vs. Constructing Explanations Digital Resource
This resource helps students differentiate between simply restating evidence and actually building a well supported CER for each kind of engagement with data.

Strategy 3: Model What “Strong” and “Weak” Conclusions Look Like

Students benefit from seeing a range of examples of data-based conclusions. For example:

Weak Conclusion: “The temperature increased.”
Stronger Conclusion: “The temperature increased steadily from 15°C to 23°C between 8am and noon, likely because the amount of sunlight increased during that time.”

Why This Matters

If we want our students to identify conclusions that use quantitative evidence, identify a pattern overall, and connect evidence to a scientific explanation then we need to provide them with examples of what that looks like. This comes back to the often shared quote “tell me and I will forget, show me and I may remember, involve me and I will understand” (attributed to Benjamin Franklin, Confucius and others). While checklists and explanations of what to do are helpful for students, they alone will not help students integrate the skills necessary to make their own good data-based conclusions. And providing examples, and discussing why they are weaker or stronger, is a GREAT way to help students be involved in this learning.

Modeling pairs like these helps students understand what you’re looking for when engaging with data literacy in the classroom.

Strategy 4: Use “Compare, Connect, Conclude” as a Scaffold

Providing students, especially our more novice students, a framework can help them develop a mental model or structure for how to build toward conclusions step-by-step. Try the 3 Cs structure:

Compare — How do two parts of the data set differ?
Connect — How do these comparisons connect to the phenomenon or question?
Conclude — What overall insight can you now make?

Try giving students a template like:

Compare: The ______ is greater/less than ______.
Connect: This might be because ______.
Conclude: Therefore, from the data I would suggest ______.

This structure helps students avoid jumping straight to a vague claim. Instead their conclusion is grounded in components of the data (compare) and includes a discussion of why that pattern may exist mechanistically (connect).

Strategy 5: Use Messy Data to Build Confidence

Real-world data is never clean in the sense that there is always variability in data values. All students intuitively know this, aka they are not all the same height, but it can get overwhelming for students when they work with that messiness in datasets.

But there are SO many benefits to have your students work with messy data (rather than cleaning all of the messiness out). For example, using messy data:

Encourages students to look for trends, not perfect fits
Teaches students to tolerate uncertainty
Sparks deeper questions and curiosity
Better represents the reality of working with data

This aligns beautifully with our upcoming February’s Strategy Share Out workshop (Messy on Purpose: Helping Students Understand Variability in Data), reinforcing the importance of giving students incomplete or imperfect datasets to analyze. If interested, join us!

Strategy 6: Provide More Opportunities for Students to Talk About Data

If you have been to one of our sessions you know that we feel strongly that discussion is one of the most underrated strategies in teaching data analysis.

Here are three talking prompts to try:

Turn and Talk: “What conclusion do you think the class should draw from this?”
Data Debate: Assign two possible claims. Students use the same data to argue for their assigned claim and against the other claim.
Gallery Walk: Students rotate between posted graphs and propose conclusion statements.

Student talk naturally builds interpretation skills and normalizes the non-linear path of sensemaking in that interpretation.

Strong Data Conclusions Come From Practice, Not Perfection

Most importantly of all though, is that supporting students to draw meaningful conclusions is a long-term investment. When students are guided to explore, question, compare, and explain, they begin to see data not as static numbers — but as information they can use to tell a story.

With small shifts in structure and classroom routines, you can help students experience more “Aha!” moments each time they encounter data.
