AI can support learning when it is designed or used to make learners think, practise, and respond to feedback. It can also help someone finish a task without showing that they understand it. The key is to distinguish supported task completion from learning that a student can demonstrate without the tool.
Does AI help you learn, or just finish the assignment?
There is no single answer for “AI in education”: a tutor that prompts a learner to explain a step is a different intervention from a chatbot that supplies a complete answer on request. Results also depend on the subject, age group, tool, teaching context, and outcome being measured. A score earned with AI available does not necessarily show that the learner can recall, explain, or apply the material independently.
One randomized undergraduate physics study compared a custom AI tutor built around pedagogical practices with active-learning lessons. Its authors reported median post-test scores of 4.5 for the AI group (N = 142) and 3.5 for the in-class group (N = 174). The study involved 194 undergraduates, two lessons, and a crossover design; the reported group counts should not be read as separate enrollment totals. The result is evidence about that tutor and those lessons, not proof that unrestricted chatbots or other courses will do as well. The authors of AI tutoring outperforms in-class active learning caution: “While these models can answer technical questions, their unguided use lets students complete assignments without engaging in critical thinking.”
A 2025 meta-analysis of 99 independent K–12 STEM studies found a small overall effect, g = 0.455 (p < 0.001; 95% CI 0.327–0.583), and high between-study heterogeneity (I² = 89.697%). In other words, the average result was positive, but the interventions and results varied substantially. The average is not a forecast for any particular class or AI product.

What the evidence says across learning settings
| Setting and evidence | What was studied | What the finding can—and cannot—tell you |
|---|---|---|
| Undergraduate physics; randomized comparison | A custom pedagogical AI tutor compared with active-learning lessons over two lessons in a crossover design. | The authors reported median post-test scores of 4.5 for the AI group (N = 142) and 3.5 for the in-class group (N = 174), within a study of 194 undergraduates. This result concerns the particular tutor and course context, not chatbots generally. |
| K–12 STEM; meta-analysis | 99 independent studies of AI-supported STEM learning. | The pooled effect was small and positive, but high heterogeneity means outcomes varied across tools, school levels, and subjects. |
| Middle-school AI literacy; classroom comparison | A teacher-led curriculum group of 89 students compared with 69 students in a comparison group. | The curriculum group showed deeper conceptual understanding and more positive attitudes in the studied setting. The comparison does not establish long-term retention. |
| High-school programming; randomized trial summarized by OECD | Students using ChatGPT support compared with a lecture-based group. | The OECD summary reports lower self-efficacy and achievement outcomes for the ChatGPT-supported students. It is a reason for caution in that context, not evidence that all coding assistance harms learning. |
| Scientific computing; course case study | Students’ and teachers’ experiences with chatbot use in a scientific-computing course. | The case study records perceived benefits as well as teacher concerns about code quality and learning. It describes a course experience rather than establishing a general causal effect. |
These studies use different designs and measure different outcomes, so they should not be treated as interchangeable votes for or against AI. The meta-analysis estimates an average across varied K–12 STEM interventions; the physics study tests a particular tutor; and the programming sources address different classroom contexts.
How to use AI so the learner still does the thinking
Use the tool to support a learning step, not to replace the step the learner is meant to practise. These approaches are practical applications of the structured-tutoring evidence, not a checklist proven as a package in a single experiment.

- Ask for a hint before a solution. Have the learner attempt the problem first, then request one hint about the next step rather than a complete answer.
- Ask for an explanation of a specific error. Name the line, concept, or step that is confusing. After reading the explanation, ask the learner to restate the idea in their own words.
- Use a worked example to create fresh practice. Ask for an explanation of an example and then a new, similar problem. The learner should solve the new one without copying the example.
- Ask questions that reveal reasoning. For example: “What assumption am I making here?” or “Which step should I check next?” Then require the learner to explain why the answer or method works.
- Verify important claims. Treat the response as something to inspect, not as automatic proof. Compare it with course materials, calculations, or a trusted reference where accuracy matters.
How students can use AI to learn coding
In programming, generated code may run without demonstrating that its author understands the language, the algorithm, or the trade-offs. The OECD-summarized high-school trial and the scientific-computing case study support a cautious approach, but they do not show that every form of coding help is harmful.
- Try the task first. Write a plan, pseudocode, or an initial attempt before asking for help. This gives the learner something concrete to reason about.
- Ask about the problem, not just for replacement code. Request an explanation of an error message, a concept, or an alternative approach. If the tool supplies code, ask what each important line does and why it is needed.
- Run and inspect the suggestion. Test it with ordinary and edge-case inputs. Check whether it meets the assignment’s requirements, handles errors appropriately, and introduces unintended behavior.
- Make the learner revise it. Change a requirement, add a test, or modify the code. Ask the student to explain what changed and why the result still works.
- Check the concept without assistance. Have the learner solve a related problem or debug a fresh example on their own.
A successful run is evidence that the program executed for the tested case; it is not, by itself, evidence that a student can explain or reproduce the underlying idea.

How to tell whether learning happened
Keep assisted performance separate from independent performance. An OECD review describes a mathematics trial in which standard ChatGPT access improved performance during the intervention, but average performance on a subsequent unaided measure was 17% lower. A structured tutor produced a larger improvement while assistance was available; its unaided post-test did not differ significantly from the control group. These are findings from that particular trial, not a general estimate of what AI does to mathematics learning.
To check learning, remove the tool for at least part of the assessment and ask for evidence that requires more than reproducing its answer:

- Recall: Can the learner retrieve the key idea without a generated explanation in front of them?
- Explanation: Can they describe the reasoning in their own words and answer a follow-up question?
- Transfer: Can they apply the concept to a new problem, changed assumptions, or an unfamiliar example?
- Revision: Can they spot and correct a flaw in an AI-generated answer or code sample?
For teachers, compare what a student can do with assistance to what they can do unaided. Those are different outcomes; reporting only assisted completion can overstate what has been learned.

AI literacy is more than knowing how to write prompts. Learners need a working understanding of AI concepts and practice using, evaluating, and creating with AI, alongside discussion of ethical questions. A 2024 teacher-led middle-school curriculum comparison found deeper conceptual understanding and more positive attitudes among 89 curriculum students than among 69 comparison students. It supports that curriculum in its studied setting, but does not establish whether the gains lasted over time.

Those percentages describe the videos analyzed; they should not be generalized to classrooms worldwide.
Questions to settle before using an AI tool in class
Evidence that a teaching approach can help does not establish that a particular product is suitable for every student or school. Before adopting a tool, teachers and institutions should check:
- Learning objective: Which part of the lesson should the tool support, and which thinking should remain the learner’s responsibility?
- Teacher oversight: How will responses be checked, and what will students do when the tool is wrong or confusing?
- Age suitability and accessibility: Can the intended learners use it effectively, including students with different access needs?
- Privacy: What student information is entered, and what do the applicable terms and school policies permit?
- Equitable access: Can all students participate, or will access to the tool create an advantage some classmates do not have?
Answers depend on the specific service, school, and jurisdiction. The studies described here do not establish current terms, privacy protections, or age suitability for any named product.
What these findings do not establish
The evidence spans distinct tools, learner ages, subjects, study designs, and measures. It does not establish one universal effect of AI on learning, durable long-term gains across classroom, STEM, and software-engineering settings, or transfer from one tool to another. The OECD also cautions that generative AI systems change quickly and that much existing evaluation concerns earlier versions. For any specific course, the practical question is not simply whether AI was available, but whether learners can explain and use what they practised after the assistance is removed.
