1) The 3-Minute Micro-Viva (Oral Check-In)
What it is: Students explain their work out loud in a short, structured “mini oral.”
Why it works: If a student understands it, they can explain it. If they don’t, you’ll hear exactly where the gap is.
How to run it (fast):
Students bring a one-page artifact (graph, CER, model, notes).
Ask 2 prompts:
1. “Walk me through your claim and your best evidence.”
2. “What’s one limitation or uncertainty?”
Marking tip: Use a 4-point rubric: clarity, evidence, reasoning, reflection.
Easy pairing: Any reading-based task or research template makes a perfect artifact. If you like scaffolded inquiry tasks, browse the article + research project template pathway such as Chemistry Reading Passage + Project Template.
2) Process Portfolios (Draft Trail + Decision Log)
What it is: Students submit the final product plus a short log showing how it evolved.
Why it works: Final answers are easy to outsource. Decision trails aren’t.
Portfolio components (keep it simple):
Draft 1 (bullets)
Draft 2 (structured)
Final
A 6–8 sentence “What changed and why?” reflection
AI-friendly version: Allow AI for drafting, but require students to highlight:
2 sentences they kept
2 they rewrote
1 they deleted (and why)
Store connection: This works beautifully with structured literacy tasks like reading passages and questions. If you want a big bank of texts to cycle through, start with your library bundle: Ultimate 209 Science Reading Passages & Questions | Article A Day.
3) “Explain Your Lab Like a Scientist” Photo Notebook
What it is: Students document a practical with photos + short captions that show what they did and what it means.
Why it works: The photos anchor authenticity. The captions reveal understanding.
Structure:
Photo 1: setup (label variables)
Photo 2: key step (what changed, what you noticed)
Photo 3: results (table/graph)
Photo 4: conclusion (claim + evidence)
Photo 5: limitation (what would you improve)
Marking tip: Grade 5 captions only (not the whole notebook).
4) CER from an Unfamiliar Dataset (Same Skill, New Context)
What it is: Give students a dataset they haven’t seen before and ask for a tight CER response.
Why it works: Copying a known explanation fails when the data is new. Understanding transfers.
Prompts that work well:
“What claim can you justify with this dataset?”
“Which data point is most important, and why?”
“What alternative explanation might exist?”
Make it easier: Give 2 sentence starters and a sample CER.
Natural add-on: Use a reading passage first to build background knowledge, then shift to the dataset. Browse subject collections like Chemistry Reading Passages.
5) Graph Talk + Error Analysis
What it is: Students interpret a graph and then explain common mistakes.
Why it works: Error analysis reveals deep understanding - students must know what’s wrong and why.
Format:
Part A: “Describe the trend in one sentence.”
Part B: “What does this point mean in context?”
Part C: “Here are 3 wrong interpretations. Fix them.”
Marking tip: Grade Part C heavily. That’s where thinking shows up.
6) Hexagonal Thinking (Connections + Justification)
What it is: Students connect concept tiles and justify the links.
Why it works: Students can’t “sound smart” without building a coherent network of ideas.
How to run:
Give 12–20 terms.
Students form a connected map.
They write 6 justifications: “I connected X to Y because…”
Ready-made option: If you want a polished version you can model with students, see a hex activity like Black Holes | Hexagonal Thinking Activity (The Teaching Astrophysicist) (the method transfers to any topic).
7) Structured Scientific Debate (Evidence Cards + Roles)
What it is: Students argue a science question using evidence, not vibes.
Why it works: Live argumentation makes thinking visible immediately. It also builds literacy, reasoning, and communication.
Project READI and related adolescent literacy work emphasizes evidence-based argumentation as a core way students show understanding in science. (Institute of Education Sciences)
Simple debate structure (30–45 minutes):
5 min: read primer + highlight evidence
10 min: prep with role cards
15 min: debate
10 min: reflection (what evidence changed your thinking?)
Ready-to-use debates:

8) “Choose Your Method” Investigation Plan (Constraints-Based)
What it is: Students design an investigation plan under realistic constraints.
Why it works: Planning reveals understanding of variables, controls, measurement, and validity—skills AI can’t supply without the student’s science knowledge.
Constraints to include:
limited time
limited equipment
ethical restriction
sample size limit
Deliverable: One-page plan + “why this method” paragraph.
Marking tip: Grade the justification, not the prettiness.
9) Two Truths & a Lie (Students Create + Defend)
What it is: Students write 2 true statements and 1 plausible lie about a topic, then defend which is which.
Why it works: Creating plausible misconceptions requires real understanding—and it flushes out shaky ideas fast.
How to run:
Students write 3 statements.
Swap with a partner who must identify the lie and explain why.
Original writer reveals and defends.
Ready-made launch option: A polished set can help you model the quality you want (and then students make their own). Example: Black Holes | Strange But True Facts + 2 Truths and a Lie (The Teaching Astrophysicist).
10) Diagnose the Misconception Quick Clinic
What it is: Give students a common wrong idea and ask them to fix it with evidence.
Why it works: Correcting misconceptions requires concept clarity + explanation.
Template:
Misconception: “____”
Why someone might think that:
What the evidence says:
Correct explanation in 3 sentences:
Marking tip: Grade the evidence sentence + reasoning sentence.
11) The 1-Page Science Brief (Jigsaw Synthesis)
What it is: Students read different sources and combine them into a concise brief.
Why it works: Synthesis across sources is harder to fake, and the choices they make (what to include, what to omit) show understanding.
Structure:
headline
5 bullet key facts
3 vocabulary terms
1 claim + 1 evidence
1 limitation or still unknown
Make it doable: Provide the reading set yourself using passages. If you want a huge topic bank for jigsaws, use Ultimate 209 Science Reading Passages & Questions.
12) Playful Retrieval with Explanation (Games That Still Show Thinking)
What it is: Use a review game - but require micro-explanations that show reasoning.
Why it works: Games boost participation; explanations keep it rigorous.
Two examples:
Students play, then must write “Why is that answer correct?” for 5 prompts.
Students create 3 new cards/questions and justify them.
Ready-to-run option for older students: Science Against Humanity | Biology | Review Card Game (The Teaching Astrophysicist).
How to Choose the Right Format (Without Overhauling Your Whole Course)
If you’re busy (and you are), here’s a simple matching rule:
And if you want to try the approach without buying anything first, there’s a solid starting point here: Free Resources (The Teaching Astrophysicist).
A Note on Fairness (Because This Matters)
When schools lean heavily on detection, it can create a climate of mistrust—and unreliable tools risk false accusations, which multiple education sources warn against. (Education Week)
The better direction is what many assessment redesign pieces recommend: shift toward authentic tasks, process evidence, and student thinking made visible. (ASCD)
That approach supports learning and protects relationships.
Closing Thought: You Don’t Need “AI-Proofing,” You Need “Thinking-Proofing”
AI didn’t ruin assessment. It exposed a weakness we already had: too many tasks valued product over process. The fix isn’t panic. It’s design.
Pick two formats from this list and use them repeatedly. Students will get better. Your marking will get clearer. And you’ll spend less time guessing what a student knows - because you’ll be able to see it.
Thanks for reading!
