“I’m doing interventions, but they’re still not getting it.”

If you’ve ever said this—or thought it—while supporting a struggling science student, you’re not alone.
You’re pulling data. You’re offering support. You’re checking for understanding. So why are your Tier 3 students still stuck?

It might be because of one major mistake—one that most teachers don’t even realize they’re making:

They’re intervening with activities, not addressing the actual barrier.

Let’s unpack what that means—and what to do instead.

🚫 The Mistake: Confusing Intervention with “Extra Practice”

Many well-meaning science teachers create an intervention block filled with:

• Reteaching the lesson again

• Giving another worksheet or vocabulary review

• Running a quick lab redo

• Having students read the textbook again

While those things might feel supportive, they often don’t address the root of the problem.

💡Here’s the truth:

If your intervention looks like your lesson… it’s not really an intervention. It’s just repetition.

 What Real Science Intervention Should Do

Effective intervention targets the underlying cause of the learning gap—not just the surface skill.

Here’s how:

Standards Say: Build Mastery, Not Memorization

Whether you're aligned to TEKS or NGSS, students aren’t expected to simply remember—they're expected to:

• Apply

• Evaluate

• Explain

• Model

• Investigate

Interventions should build those thinking pathways—not just fill time with extra practice.

✅ TEKS Tip: Many science TEKS begin with verbs like “analyze,” “evaluate,” and “model.” If students can’t perform those tasks independently, they may need strategic scaffolds—not just more instruction.

 Real-Life Example from the Classroom

A 7th grade teacher noticed her Tier 3 students couldn’t explain how thermal energy affects molecular motion. She had already retaught it, given a lab, and assigned a review video.

But the turning point came when she tried a simple intervention shift:

• She asked students to draw a cartoon strip showing molecules during heating and cooling.

• They used arrows, faces, and motion lines.

• Then, using a sentence frame, they explained what each part showed.

For the first time, they weren’t just repeating the right answer—they were demonstrating true understanding.

That’s the power of addressing the real gap.

What You Can Do Differently (Starting Tomorrow)

To avoid this common intervention mistake, try these 4 shifts:

1. Start With Diagnostic Data

Use quick probes, error analysis, or verbal check-ins to pinpoint the misconception—not just the wrong answer.

2. Use Different Modes

Incorporate drawing, building, sorting, or speaking into interventions—especially for Tier 3 students who need multimodal input.

3. Slow Down the Language

Academic language is often the barrier. Use sentence stems, speaking scaffolds, and structured discussion routines to build conceptual understanding.

4. Make It Small and Targeted

Don’t reteach the unit. Zoom in on the one thing that’s causing the disconnect. One misconception, one term, one connection—that’s where the magic happens.

💬 Final Thoughts

You’re already doing the work. You care deeply. But when students keep failing—even after you’ve done “all the things”—don’t blame yourself.

Instead, shift the strategy.

Intervention isn’t about doing more—it’s about doing the right things, intentionally.

And that starts with identifying the real barrier, not just reteaching the content.
