Breaking the Rubric: Using AI to Teach the Art of Reflection

As a mathematics teacher, I often find that the biggest hurdle for my Year 1 IBDP students isn’t the math itself—it’s the communication. They are comfortable with formulas, but when it comes to the Internal Assessment (IA), they are suddenly asked to be technical writers, a modality many haven't explored in a math context before.

This week, I decided to tackle this "writing anxiety" by using Gemini to create a "perfectly imperfect" learning experience.

The Strategy: Designing the "AI Sacrifice"

Instead of showing students a gold-standard IA that might feel unattainable, I used AI to generate three sample pieces of coursework that were intentionally flawed. To do this, I leaned on my TPACK (Technological Pedagogical Content Knowledge)—matching the pedagogical goal of "critical analysis" with the technological ability of an LLM to follow highly specific, "bad" instructions.

I prompted Gemini to create samples with:

• Poor Formatting: Unlabeled tables and missing units of measurement.

• Logical Gaps: Chi-squared tests with expected values less than 5 (a classic IB "no-no").

• Lazy Evidence: Blurry photos of a TI-84 calculator screen instead of clear, digital representations.

• Shallow Language: Analysis that described the "what" but never the "why."

  
  

Moving Up the SAMR Scale

In my Masters studies, I’ve been focusing on the SAMR model and how we can use tech to not just replace paper, but to redefine the task.

1. Substitution/Augmentation: Rather than just reading a rubric, students were grading. But the real shift happened in the how.

2. The Multimedia Pivot: Students used Padlet as a launchpad. Because this was their first time "writing" for math, I removed the barrier of the blank page. I invited them to use their own words through audio clips and video justifications.

By allowing them to speak their critiques, I could hear their "student voice" immediately. This Augmentation allowed me to quickly assess who understood the criteria and who was still struggling with the nuances of the IBDP marksheet.

The Blended Classroom in Action

The magic happened in the interplay between the digital and the physical. While the Padlet was the repository for their thoughts, the classroom was alive with facilitated arguments.

As I moved around the room, I wasn't lecturing; I was a moderator. Students were debating whether a blurry calculator photo deserved a 1 or a 0 for "Presentation." They were arguing over the validity of the Chi-squared conclusions. The tech provided the "low-stakes" entry point, but the blended environment allowed for high-stakes intellectual debate.

Beyond the Process

My philosophy for edtechequation has always been: How can we use tech to stimulate analytical thinking rather than just automating the process?

By using AI as the "guinea pig" for critique, my Year 1 IBDP students learned that mathematics is as much about the quality of the argument as it is about the calculation. They walked away not just knowing the rubric, but having lived it.

Reflection for Peers

If you're looking to try this, remember that the power of AI in the classroom isn't just in what it can do right, but in how its mistakes can be used to sharpen our students' critical lenses
