Research update — 23 October 2026. Adaptive learning in primary maths is often promoted as a way to personalise practice for every child. A research update from Radboud University on 2 October reported a large, multi-year study of 7,885 Dutch primary-school pupils: children using an adaptive learning system showed slightly more positive growth in mathematics performance than peers in classes that did not use it. The result is encouraging, but its limits matter just as much as the headline.
The key lesson is not that software can replace a teacher. It is that adaptive practice may help teachers respond to differences between learners—when it is connected to a clear curriculum, interpreted by educators, and evaluated through learning rather than screen activity.
What did the 7,885-pupil study find?
According to Radboud University’s research summary, researchers examined the development of numeracy skills among 7,885 Dutch primary-school pupils over a three-year period. The data covered the years 2014–2017, when classes using an adaptive learning system were compared with classes teaching mathematics without that system.
The software adjusted the difficulty of exercises in response to pupils’ performance: learners doing well received more challenging tasks, while those struggling received simpler ones. The university reported a small, generally positive trend in maths growth. The effects appeared more evident in larger schools and in schools serving more socio-economically disadvantaged pupils, where differences in prior attainment may be harder for one teacher to address simultaneously.
The study is reported as Arithmetic Development: A Longitudinal Observational Study into the Use of Adaptive Technology, listed by the university as forthcoming in Learning and Instruction. The important distinction is methodological: this was a longitudinal observational study, not a randomised trial. It can identify a pattern across a large sample, but it cannot by itself establish that the software caused every difference observed.
Why “adaptive learning” is not the same as a chatbot
Searches for AI learning tools often group very different technologies together. An adaptive maths platform typically selects or adjusts practice tasks using a learner’s answers and progress data. A generative AI chatbot produces new explanations or responses in natural language. Some products combine both, but the evidence for one type should not automatically be treated as evidence for the other.
The Dutch study examined adaptive learning technology used in 2014–2017—well before today’s generative AI chatbots became widely available. It therefore offers useful evidence about personalised practice and learner progression, but it does not demonstrate that a conversational AI tutor improves maths learning. For a separate discussion of how to judge education tools, see our guide to evaluating AI learning tools in schools.
What the findings mean for primary-school teachers
1. Use software to target practice, not to define the curriculum
Adaptive systems can vary the pace and difficulty of practice, but teachers still need to decide which mathematical ideas pupils should understand. A platform’s next-task recommendation is not a substitute for curriculum sequencing, classroom discussion, or professional judgement. Before adopting a tool, map its activities to the learning objectives and identify which concepts require direct explanation or concrete materials.
2. Ask pupils to explain their reasoning
Correct answers alone do not reveal whether a child understands place value, has memorised a procedure, or guessed successfully. Pair digital practice with brief explanations: “How did you work it out?”, “Why does this answer make sense?”, or “Can you show another method?” Teachers can use recurring errors as prompts for a small-group lesson instead of assuming that a progress dashboard tells the whole story.
3. Check transfer away from the platform
Improvement inside an app is not necessarily the same as durable learning. Periodically give pupils a short, curriculum-aligned task on paper or at the board, without hints from the software. Include a new problem that requires the same underlying idea in a different form. If performance drops sharply when the tool is removed, the next step may be more explanation and guided practice—not simply more app time.
4. Keep the teacher in the feedback loop
The Radboud report explicitly stresses the continuing role of teachers. A useful workflow is to review the platform’s error patterns, compare them with classwork, select one misconception to address, and then check whether pupils can apply the correction independently. Automated feedback can make practice more responsive, but it may not reveal language difficulties, anxiety, gaps in prior knowledge, or the reason a child chose an answer.
5. Test whether the tool is equitable in your setting
The reported stronger pattern in larger and more disadvantaged schools is worth investigating, not a guarantee that every under-resourced school will benefit. Schools should check device availability, connectivity, accessibility, language support, and whether the tasks reflect pupils’ curriculum and context. Ask which learner data are collected, how long they are retained, who can access them, and whether teachers can export or delete them under the school’s policies.
How schools can evaluate an adaptive maths tool
Before expanding a platform, schools can run a small, time-limited evaluation. Agree on the learning objective first, record a baseline measure, and decide what evidence would count as improvement. Where feasible, compare results with a similar class or with pupils’ performance before implementation, while acknowledging that simple before-and-after comparisons cannot rule out other explanations.
- Learning: Do pupils improve on curriculum-aligned questions, including questions they have not practised in the platform?
- Retention: Can they still solve comparable problems after a delay?
- Reasoning: Can they explain a method and detect an implausible answer?
- Equity: Are gains and access similar across groups, or are some pupils receiving less useful practice?
- Teaching: Does the system give teachers actionable information and free time for instruction, or add monitoring work?
- Privacy and reliability: Are data use, security, accessibility and failure procedures documented?
These checks complement, rather than replace, the research literature. A 2025 open-access meta-analysis of 34 empirical studies on learning-analytics interventions reported an overall positive effect on learning outcomes, while also finding substantial variation across studies. That broader evidence concerns learning analytics interventions generally—not only AI systems or primary mathematics—so it supports careful evaluation rather than a universal claim of effectiveness. See the published meta-analysis for methods and limitations.
What the evidence does not yet tell us
Three cautions should shape decision-making. First, a small average benefit can conceal variation between pupils, schools, and implementation models. Second, data from one national context and a particular generation of adaptive software may not transfer unchanged to schools with different curricula, languages, resources, or teaching practices. Third, evidence about adaptive exercise selection should not be used to make stronger claims about generative AI tutors, which introduce different questions about accuracy, explanation quality, privacy, and student dependence.
Research on AI-supported learning more broadly similarly points to implementation as a central issue: a recent review in the Italian Economic Journal argues that the impact of computer-assisted learning and AI-guided tutors depends on curriculum alignment, teacher preparation, interactive design, and sustained human support. Read the open-access review of AI-guided tutors and computer-assisted learning for a broader synthesis.
A practical conclusion for schools
The 7,885-pupil study offers a useful reminder that adaptive learning in primary maths should be judged by the quality of learning it supports, not by the novelty of the technology. Its reported gains were small, the design was observational, and the data predate the current generative-AI wave. The most defensible response is neither blanket adoption nor blanket rejection: choose tools that fit the curriculum, use their data to inform—not automate—teacher decisions, and verify progress with independent tasks and transparent evaluation.
