Power, Prescription, and Postpositivism: Considerations for collecting and representing neurodiversity demographic information in physics education research
This paper critiques the reliance on prescriptive diagnostic methods for collecting neurodiversity data in physics education research, arguing instead for a participant-centered framework that prioritizes self-identification to enhance data authenticity, trustworthiness, and accessibility.

Imagine you are trying to take a group photo of a diverse crowd of people. To make the photo useful, you need to know who is in it. Are they artists, engineers, or chefs? Are they tall, short, or somewhere in between?
This paper is about how researchers in Physics Education (people who study how students learn physics) are currently taking that "group photo" of students with neurodivergent minds (people whose brains work differently, like those with ADHD, autism, dyslexia, or bipolar disorder).
The authors argue that right now, researchers are taking the photo in a way that blurs the faces and forces everyone into the same generic box. They propose a new way to take the picture that actually shows the unique details of each person.
Here is the breakdown of their argument using simple analogies:
1. The Problem: The "Prescriptive" vs. "Descriptive" Approach
The paper uses a clever analogy from language to explain the problem: Prescriptivism vs. Descriptivism.
- The Old Way (Prescriptivism): Imagine a teacher who tells a student, "You must speak this way because it is the correct way." In research, this is when a scientist says, "You must check the box for 'Learning Disability' if you have an official medical diagnosis."
- The Issue: This is like forcing everyone into a single, giant bucket labeled "Disabled." It ignores the fact that one person might have dyslexia, another might have ADHD, and a third might have both. It also assumes that if you don't have a doctor's note, you don't belong in the bucket. This forces people to fit into a box that might not actually fit them.
- The New Way (Descriptivism): Imagine a teacher who asks, "How do you describe your own voice?" In research, this means asking students, "How do you identify?" and letting them use their own words.
- The Benefit: This is like letting people describe their own outfits. One might say, "I'm a painter with glasses," and another might say, "I'm a coder who uses a wheelchair." It captures the messy, real, human reality rather than a clean, fake category.
2. The "Gap Gazing" Trap
The authors looked at 47 different studies about neurodivergent students in STEM (Science, Tech, Engineering, Math). They found that many researchers were doing something called "Gap Gazing."
- The Analogy: Imagine looking at a forest and only counting the trees that are "sick" versus "healthy," without ever asking the trees what they feel like.
- The Reality: Many studies just lumped everyone into a giant, vague category like "Learning Disability" or "Neurodivergent" without asking which specific differences the students had.
- Why this is bad: If you mix everyone into one big pile, you lose the specific details. You can't tell if a teaching method works for someone with dyslexia if you've mixed them in with someone who has ADHD. It's like trying to fix a car engine by treating all cars as if they are the same model.
3. The Power Dynamic: Who Holds the Pen?
The paper argues that when researchers force people into pre-made categories, they are holding the pen and deciding who gets to be who.
- The Metaphor: It's like a costume party where the host hands everyone a mask and says, "Wear this mask; it's the only real one."
- The Result: This strips people of their power to tell their own story. It assumes the researcher knows better than the student what their identity is. The authors say this is unfair and scientifically weak because it creates a fake version of reality.
4. The Solution: The "NEURO-ID" Approach
The authors propose a new set of guidelines called NEURO-ID. Think of this as a "Bottom-Up" approach.
- How it works: Instead of starting with a list of medical diagnoses (Top-Down), researchers start with the student's own story.
- Step 1: Ask the student to describe themselves in their own words.
- Step 2: Group those stories together after you hear them.
- Step 3: If you need a big category (like "Neurodivergent"), make sure you also list the smaller, specific details underneath it (like "Autism," "ADHD," "Bipolar").
- The Goal: To create a map that is detailed enough to be useful for other scientists, but flexible enough to be honest about who the people actually are.
5. Why This Matters
The authors say that getting this right isn't just about being nice; it's about accuracy.
- If we use the "Big Bucket" method, we might miss the fact that a specific teaching strategy helps one type of student but confuses another.
- By using the "Descriptive" method, we can see the full picture. We can celebrate the diversity of minds in physics rather than trying to force them all to look the same.
Summary
In short, this paper tells physics researchers: Stop forcing students into rigid, medical boxes. Instead, ask them how they see themselves, listen to their answers, and build your data categories based on their reality, not your assumptions. This makes the research more honest, more useful, and more respectful of the people being studied.
