AI-polished writing is erasing student voice, research finds
Seventy-three percent of Canadian students use generative AI for schoolwork, and nearly half say it's their first instinct. But a growing concern runs deeper than academic misconduct: students worry their AI-assisted writing no longer sounds like them.
A KPMG Canada survey of 684 students found that many feel uneasy about the tool's role in their assignments. They recognize the writing is technically stronger. It's also generic-indistinguishable from what any other student might produce.
One student described the tension plainly: "It's better writing, yeah, it sounds good and helps get a better grade. But it's kinda generic. Like anyone could've written it, not just me."
Writing is how students build professional identity
For STEM students especially, writing does more than communicate ideas. It's how they position themselves as emerging professionals and explore whether they belong in their field.
Research on STEM education shows that communication is central to scientific practice. Yet many programs treat writing as secondary to technical skills. Students navigate unwritten rules about what counts as credible and legitimate in their discipline-and they do this partly through how they write.
When AI smooths writing into a standardized style, it can feel like self-erasure. Some students lower their guard and access support they needed. Others lose the chance to develop their voice as a professional asset.
The belonging problem
In Canada, STEM participation remains uneven across gender, race, socioeconomic status, and immigrant background. Many students already question whether they belong.
If AI-generated writing becomes the implicit standard for good work, students may begin to locate competence in the tool rather than in themselves. Those who rely on AI might question the authenticity of their success. Those who avoid it may feel disadvantaged.
Recognition matters. For students already marginalized in STEM fields, this distinction can affect whether they see themselves as capable.
What educators can do
Canadian post-secondary institutions are still determining their policies on AI use. Many allow limited use while requiring disclosure, but enforcement remains unclear.
Clearer expectations help. Students should not have to guess what's acceptable. Assessments should make students' thinking visible, not just the final product.
Instructors can ask students to:
- Explain how they used AI in an assignment
- Compare an AI-generated paragraph with their own and discuss what changed in tone, clarity, and reasoning
- Revise AI-polished text so it reflects their own thinking
- Identify where their interpretation and uncertainty matter
These shifts foreground not only what students produce but also how they think and position themselves in their work.
Writing in one's own voice must be treated as a skill worth developing. AI is here to stay. The question is whether classrooms will help students use these tools without losing their voice and sense of belonging.
For writers navigating these tools professionally, the stakes are similar. AI for Writers resources can help you maintain your voice while using these systems effectively. For educators rethinking how students learn with AI, AI for Education covers practical classroom strategies.
