Artificial intelligence and homework: helping a student without doing the work for them

A complete answer copied without understanding can produce homework that looks successful without consolidating any knowledge. Before opening ChatGPT or an AI homework tool, check the teacher’s instructions, the tool’s access conditions and the confidentiality of the information you share. During the exercise, ask for questions and hints rather than a solution ready to hand in.

The question is not simply “allow or ban AI”. A student can use it to understand why an equation is causing trouble, or hand over the whole solution to it. The same interface can support learning in the first case and short-circuit it in the second.

1. What AI can usefully explain before and during homework

Generative AI produces an answer from a request written in natural language. It can rephrase an explanation, suggest a different example or break a difficulty down into steps. However, it does not automatically know the student’s exact lesson, their teacher’s expectations or their previous reasoning. The context provided by the user and checking the answer remain essential.

The framework for the use of AI in education issued by the ministère de l’Éducation nationale (the French Ministry of Education) recognises opportunities to support understanding and practice, while requiring real educational added value. Just because a task can be automated does not mean it makes sense to automate it.

Before starting: clarify the instructions, do not ask for the homework

Suppose a student in 4e (the third year of collège) has to write an argued paragraph. They can ask: “Explain what it means to justify an argument, with an example different from my topic.” The tool can help distinguish an idea, an explanation and evidence. On the other hand, submitting the exact assignment with “write my paragraph” hands over precisely the skill that needs to be practised.

In maths, they can ask for an accessible definition of proportionality or a counter-example, then check these explanations against their textbook. In a language, they can ask why two verb tenses are not used in the same situation, without having the whole piece of writing they must produce themselves translated for them.

During the exercise: step in at the first identified blockage

The right moment to ask for help is often when the student can name their obstacle: “I don’t know how to isolate x” or “I don’t understand what the document proves”. If they have not tried anything yet, it is better to start by rereading the instructions, finding the data and writing down a first idea.

A tool can then ask which property would be relevant, recall a condition for applying it or suggest a simpler, similar exercise. It does not need to display the whole correction: the aim is to make the next step possible, carried out by the student.

2. The risk: handing in correct homework without having learnt anything

A well-presented solution and knowledge that has really been acquired are two different things. A student can copy out an impeccable proof and then be unable to explain why the first equality is true. The visible success of the homework then partly measures the tool’s abilities, not just the student’s.

A field experiment published in 2025 in PNAS studied nearly a thousand secondary school students in maths at a school in Turkey. The researchers compared an assistant close to a general-purpose interface, a tutor version with hints built with teachers, and a group without AI. The equipped groups did better on the exercises while they had the tool. But in a later test without AI, the group that had used the general-purpose assistant scored lower than the control group; this decline did not appear in a statistically significant way with the tutor version that included safeguards. The study concerns this set-up, this subject and this context: it does not show that any use of AI harms learning, nor that an AI tutor guarantees progress.

Another experimental study published in PLOS ONE evaluated, with 274 participants, hints generated by ChatGPT across different areas of mathematics. Under the conditions studied, AI-generated help produced learning gains, with no statistically significant difference from help written by human tutors. These were, however, help materials built into a structured task, not permission to copy homework. Taken together, these results show that how the help is designed, and what the student does with it, matter more than a simplistic opposition between “good AI” and “bad AI”.

The decisive test: redo it without help

After an explanation, close the tool and ask the student to solve a variant or rephrase the method. If they only reproduce the AI’s sentences, go back to a more basic step. If they can identify the difficulty, choose a method and justify their choices on a new question, the help has at least led to observable ownership.

This check echoes the principle of active recall: trying to retrieve knowledge without looking at the answer, then checking. This is precisely what 20 minutes of active revision using a session replay makes possible. The point is not to ban corrections, but not to mistake them for proof of mastery.

3. Which questions should you ask AI to guide reasoning?

The way the request is worded makes a concrete difference to what the student does. “Do the exercise” gives the tool the role of writer. “Ask me a question to find the first step” gives it a supporting role, even though nothing guarantees it will always follow that instruction. The student must remain able to reject an answer that gives too much away.

Real need	Request to favour	To avoid
Understanding a question	“Rephrase the instructions without solving them and ask me what information is given.”	“Give me the answer.”
Getting unstuck on an equation	“I tried this first step: is it valid? Give me a hint, not the full solution.”	“Solve it and write it all out.”
Preparing a piece of writing	“Ask me questions to organise my ideas without writing my text.”	“Write an assignment I can hand in.”
Understanding a mistake	“Point out the first incorrect line and explain why, without redoing the whole exercise.”	“Replace my work with the correction.”
Revising a lesson	“Ask one question at a time; wait for my answer before correcting.”	“Summarise everything: I don’t need to reread it.”

Example: an equation in four exchanges

A student has to solve 3(x + 2) = 18. They start by writing 3x + 2 = 18: this is a mistake with the distributive property. Instead of asking for the solution, they can enter just the equation, with no name and no identifiable piece of work, together with their attempt: “Show me only the first mistake and ask me a question so I can correct it.”

The expected question might be: “What do you need to multiply each term in the brackets by?” The student then writes 3x + 6 = 18, continues to x = 4, then checks in the original equation: 3(4 + 2) = 18. If the AI gives x = 4 directly anyway, the student hides that answer and starts again from their incorrect line.

The final exchange should take place without the assistant: a similar equation with different numbers makes it possible to check that the distributive property has been understood. This step distinguishes a pleasant interaction from learning that can genuinely be reused.

4. Check the answers, the references and the data you send

An AI can state a wrong answer in a very confident tone, invent a reference, apply the wrong rule or forget a condition. The CNIL (the French data protection authority) points out that generative systems can produce results that are inaccurate but plausible, sometimes called “hallucinations”. A fluent paragraph is not proof of truth.

Check against a source that is authoritative for the task

For a school exercise, first compare the method and vocabulary with the lesson, the textbook or the teacher’s instructions. A formula may be mathematically correct but not match the method expected at the level being studied. For a historical event, check dates and interpretations in the textbook or an identified documentary source. For a literary quotation, find it in the work rather than assuming it exists because the AI has put it in quotation marks.

A reference must be traceable and must actually contain the claim being made. Asking the same assistant “are you sure?” is not an independent check: it may repeat or rephrase the mistake. If no one can confirm an important piece of information, do not use it in the homework.

Do not hand identifiable homework to a consumer service

The CNIL recommends supervising minors’ use of AI, including for homework. In particular, it advises avoiding personal data in requests and reminding students that a conversation with an AI is not a private exchange with a real person. The ministerial framework also asks users not to enter confidential or personal data into consumer tools.

So avoid sending a whole piece of work bearing the student’s name, class and school, a named teacher’s comment, a photograph of other children or family information. Retyping only the relevant question or using a generic example limits exposure. Removing the name does not guarantee real anonymisation if other details can still identify someone. Check the terms of use, privacy settings and age limits of the service you choose. For example, ChatGPT’s European terms of use require parental permission for users under 18, in addition to a minimum age for access.

5. Ask AI to create exercises rather than do the homework

An often more relevant use is to create extra work that is separate from the homework set. The tool can suggest an equation at the same level with different values, a few vocabulary questions or a practice question based on a skill described without any confidential document. These are generated suggestions, not exercises certified as matching the curriculum: the question and its correction must be checked before use.

For example, after a lesson on percentages, the student can ask: “Give me three increasingly difficult problems on percentage changes. Give only the questions. Correct after each answer and explain any mistake.” They attempt each question in their exercise book, then compare. A parent or tutor can check that no inconsistent data or wrong answer has crept into the set.

In French, you can ask for a question on a copyright-free text or a general grammar point, then write the answer yourself. For a modern language, producing a sentence from a given word is generally more educational than retrieving a complete translation ready to hand in. If the teacher forbids the use of AI for the homework in question, keep these uses for situations they explicitly allow.

After the exercise: measure what holds up without the tool

The practice session should not stop at “the AI gave me five correct corrections”. Keep a new question for the next day or a few days later, without the assistant. If the same mistake comes back, go back over the mechanism rather than multiplying generated exercises. If the student can explain and apply it alone, the help has served a specific purpose.

Research on educational AI remains mixed. A systematic review of 71 empirical studies published in Educational Research Review finds positive potential for some kinds of learning, but also methodological limitations, notably short interventions and sometimes insufficient educational scaffolding. It does not allow anyone to promise that an exercise generator will automatically suit every student.

6. The role of the parent and the tutor: set the framework, do not monitor every click

Before letting a child use AI for homework, start with the school’s rules and the instructions for the assignment. The national framework published by the Éducation nationale states that having AI do homework without explicit permission and without personal ownership counts as cheating. It provides for awareness-raising without direct use of generative AI in primary school, limited and supervised educational use in class from 4e onwards, and independent use at lycée (upper secondary school) only within a learning framework defined by the teacher. This does not amount to general permission to use it for all homework.

If the teacher allows limited use, the parent can ask the student to describe what they did: “What question did you ask? What did you correct? Can you redo the exercise now?” There is no need to read every conversation in full. The aim is to check ownership and gradually protect the child’s independence.

The teacher, for their part, can specify which steps allow assistance, which work must be entirely personal and how permitted uses should be declared. They can ask for an oral explanation, a rough draft or an in-class solution to understand the student’s approach. The Ministry advises against relying on detectors of AI-generated text, which it considers unreliable and liable to make false accusations. A suspicion should therefore not be treated as automatic proof.

A family agreement that is easy to apply

Set a rule before the next piece of homework, based on the six-step routine suggested at the end of this article. Add a confidentiality rule: no personal data or identifiable work in a consumer tool. If the school’s rules are stricter, they take precedence for the homework in question.

To distinguish between an occasional need for help and longer-term support, our article on homework help and private tutoring looks at precisely these two situations. If the student easily loses focus in front of screens, our advice on concentration during online sessions suggests adjustments to the environment and the activity.

7. An AI assistant and a tutor do not solve the same problem

An assistant can be available when a question comes up and quickly provide a rephrasing or a hint. A tutor can observe reasoning over time, link several mistakes to the same prerequisite, choose a progression, adjust their explanations and talk things through with the student. The difference is therefore not simply that one is digital and the other human: it lies in responsibility for diagnosis, follow-up and educational decisions.

Need	What AI can offer	What still requires a human decision
Instructions not understood	A rephrasing or a generic example.	Checking that the rephrasing matches the actual instructions.
One-off blockage	A hint or an intermediate question.	Identifying the missing prerequisite if blockages keep recurring.
Practice	Suggested questions and exercises.	Checking the level, accuracy and relevance of the corrections.
Progress over several weeks	Occasional help with revision.	Assessing what has been learnt, setting priorities and adjusting goals.
Assessed work	Only the uses explicitly allowed.	Setting the rules and judging the student’s own work.

This is also the distinction drawn by UNESCO in its guidance on generative AI: use in education must remain human-centred, take age into account and protect data, rather than making automation an end in itself.

On NOEO, Noé supports reasoning

Noé, the AI study assistant, aims to help the student move forward through reasoning rather than handing them the answer directly. The student can add the exercise they are stuck on themselves; you should not assume that Noé automatically knows their homework, their lesson documents or the full context of their exchanges with the tutor.

Noé does not replace the private tutor. On NOEO, one-to-one online tutoring is always delivered by a human, and after each session the tutor produces a session report that can set out, among other things, the points worked on, difficulties and work to prepare. This follow-up helps pick up a persistent mistake in the next session rather than multiplying one-off answers with no overall view. The page How NOEO works before, during and after the session presents this sequence.

Noé is available without a subscription, within any usage limits that may apply. This guarantees neither the accuracy of every answer, nor a complete correction of marked work, nor automatic progress. The student must always check important information and be able to redo the exercise on their own.

A concrete routine for AI-assisted homework

1. Check permission: does the teacher allow this form of assistance for this piece of work?
2. Try alone: read, search, write a first attempt and identify the blockage.
3. Make a limited request: a rephrasing, a first hint or a question about one step.
4. Check: compare the explanation with the lesson and verify any important reference.
5. Produce: write the reasoning and the answer yourself, following the teacher’s instructions.
6. Close the tool: redo a variant without help and note what is still difficult.

If the task can already be solved with the textbook or a question to the teacher, AI is not essential. If it unblocks a specific step and then makes way for personal work, it can be useful.
