Substitutive AI or expansive AI
The difference lies in whether the experience reduces or expands understanding, judgment and transferable learning. The same tool can produce opposite educational effects.

The difference is not in the tool. It is in whether the experience reduces or expands understanding, judgment and transferable learning.
The decisive question
When students use AI, the important question is which part of the thinking the person keeps developing:
- Understand — interpreting and connecting ideas, or just receiving an answer?
- Decide — taking justified decisions, or delegating the choice?
- Review — contrasting, improving and correcting, or accepting the first version?
- Transfer — can they use what they learned in another context?
Two ways of using AI
Substitutive AI: AI solves and the person submits. It summarises before understanding. It writes before own judgment is developed. It solves before deciding. It improves the form without working the substance. It accelerates delivery, but weakens understanding.
Expansive AI: AI expands thinking and the person understands, decides, reviews and transfers better. It brings perspectives and stimulates questions. It fosters contrast and gaps that deepen. It supports revision, improvement and new versions. It strengthens understanding, judgment and transfer.
The same tool can produce very different educational effects.
The same tool, two effects
- Chatbot — substitutive: asking for a final answer to copy and submit. Expansive: asking for questions, objections, alternatives and examples to think better.
- Text or presentation generator — substitutive: producing ready-to-submit materials. Expansive: organising one’s own ideas after researching, deciding and prioritising.
- Agent or team of agents — substitutive: delegating a complete task from start to finish. Expansive: contrasting perspectives, simulating debate, reviewing criteria and creating learning scenarios.
- Tutor or AI feedback — substitutive: seeking quick correction to finish sooner. Expansive: receiving questions, hints and feedback to improve thinking and production.
What a well-designed experience must ensure
- Human and technical competencies to develop — defining what we want to mobilise and integrate, with a clear purpose in each phase.
- A meaningful question or challenge — demanding interpretation, decision and judgment.
- Moments of contrast — comparing answers, perspectives and possible paths.
- Versions and improvement — working revision, iteration and feedback.
- Metacognitive reflection — making visible how it was thought and why it was decided that way.
- Transfer — using what was learned in a new or real situation.
This approach draws on Hattie, Dewey, Lemov, Black & Wiliam, Kolb, OECD — The Nature of Learning and UNESCO/OECD guidance on AI.
The question changes
Do we use AI to offload work, or to expand understanding, judgment and transferable learning?
