AI tutoring can safely and effectively support students: An exploratory RCT in UK classrooms (2512.23633v1)
Abstract: One-to-one tutoring is widely considered the gold standard for personalized education, yet it remains prohibitively expensive to scale. To evaluate whether generative AI might help expand access to this resource, we conducted an exploratory randomized controlled trial (RCT) with $N = 165$ students across five UK secondary schools. We integrated LearnLM -- a generative AI model fine-tuned for pedagogy -- into chat-based tutoring sessions on the Eedi mathematics platform. In the RCT, expert tutors directly supervised LearnLM, with the remit to revise each message it drafted until they would be satisfied sending it themselves. LearnLM proved to be a reliable source of pedagogical instruction, with supervising tutors approving 76.4% of its drafted messages making zero or minimal edits (i.e., changing only one or two characters). This translated into effective tutoring support: students guided by LearnLM performed at least as well as students chatting with human tutors on each learning outcome we measured. In fact, students who received support from LearnLM were 5.5 percentage points more likely to solve novel problems on subsequent topics (with a success rate of 66.2%) than those who received tutoring from human tutors alone (rate of 60.7%). In interviews, tutors highlighted LearnLM's strength at drafting Socratic questions that encouraged deeper reflection from students, with multiple tutors even reporting that they learned new pedagogical practices from the model. Overall, our results suggest that pedagogically fine-tuned AI tutoring systems may play a promising role in delivering effective, individualized learning support at scale.

Evaluation of LearnLM: AI Tutoring in UK Classrooms
Experimental Design and Methodology
The paper presents an exploratory, in situ RCT (N=165 students) across five UK secondary schools, leveraging the Eedi mathematics platform to rigorously evaluate the pedagogical efficacy and operational safety of LearnLM—a generative AI system fine-tuned for educational dialogue. The Eedi platform provided two interventions: static hints targeting specific misconceptions and interactive, chat-based tutoring. For the tutoring condition, further randomization determined whether the student interacted with an expert human tutor or with LearnLM, whose outputs were supervised and edited by qualified educators before reaching the student.
Figure 1: Progression of students through the study unit, mapping the intervention and subsequent assessment phases.
Supervising tutors reviewed every LearnLM message, with the remit to approve, minimally edit, or rewrite before delivery. This design facilitates direct head-to-head comparisons on multiple axes: AI supervision versus human-only tutoring, as well as interactive versus static support. Data collection encompassed full tutoring transcripts, student responses, system metrics, and qualitative feedback via surveys and interviews.
Safety and Reliability of AI Tutoring
A comprehensive audit over 3,617 LearnLM-generated messages revealed a high standard of safety and factual accuracy: 76.4% of messages were accepted with zero or minimal (≤2 characters) edits, most others requiring only minor stylistic adjustments (primarily emoji deletion). Out of all generations, only five factual errors (0.1%) and no instances of harmful content were detected in post-hoc review. The findings corroborate the reliability of a pedagogically-constrained, supervised LLM-driven tutoring workflow in operational classroom settings.

Efficacy: Quantitative and Qualitative Learning Outcomes
Immediate and Near-Term Learning
For mistake remediation, both human tutors and LearnLM produced substantial gains over static hints: 91.2% and 93.0% of students corrected their mistakes after tutoring, versus 65.4% for static hints (95% CrI). Misconception resolution (i.e., answering any follow-up on-topic item correctly) was similarly improved: 94.9% (human), 95.4% (LearnLM), against 86.8% (static hints). Bayesian estimation signals near-certainty that both forms of tutoring surpass static hints on immediate learning measures.

Transfer and Generalization
Crucially, LearnLM demonstrates an advantage over human-only tutoring for inter-topic knowledge transfer. After being tutored by LearnLM, 66.2% of students answered the initial question in the following, distinct study unit correctly, compared to 60.7% with human tutors and 56.2% for static hints. The average treatment effect for LearnLM over human tutoring is +5.5 percentage points (93.6% credible, Bayesian posterior). These results suggest a nontrivial effect on transfer, not merely short-term remediation.
Tutor and Student Perceptions
Interviews and surveys with expert tutors emphasized LearnLM's robust generation of Socratic dialogue—prompting deeper reasoning and reflection in students. Multiple tutors noted professional learning, having adopted model-inspired questioning strategies. The main intervention by tutors was to adjust pacing or infuse social-emotional nuance, mitigating instances where persistent probing risked disengagement. Student feedback indicated higher mean helpfulness ratings for interactive tutoring relative to static hints.
Operational and Practical Considerations
Simulation studies indicated that supervised LearnLM sessions allowed tutors to concurrently manage a greater number of students—increasing average concurrency from 2.3 to 3.5 ongoing sessions—and reducing total cost-per-session by 13.6%. AI inference fees were negligible relative to labor costs. This empirical signal in workflow efficiency fortifies the argument for AI-assisted, supervised tutoring as a lever for scalable 1:1 instruction.

Limitations and External Validity
While results in secondary mathematics are robust, generalization to domains emphasizing open-ended, interpretive reasoning (e.g., literature, history) remains an open problem, given the well-structured, misconception-tagged question corpus in mathematics. Additionally, session-level randomization and alternating human/AI tutor support may lead to underestimation of longer-term or compounding effects, as well as potential cross-condition contamination (tutors learned from supervising LearnLM).
Implications and Future Work
The findings substantiate the contention that pedagogically-constrained, supervised LLMs can deliver learning outcomes on par with, and in the case of knowledge transfer, superior to, expert human tutors in a highly-structured secondary mathematics context. These results provide a benchmark for the responsible, scalable deployment of AI tutoring, conditional on continued expert oversight to ensure dialogic quality, appropriate pacing, and accommodation of affective signals.
However, several open challenges remain. Achieving unsupervised, fully autonomous deployment with similar reliability and quality, handling ill-structured or ambiguous subject-matter, and dynamic adaptation to real-time student affect require further LLM fine-tuning and multimodal sensing. Longitudinal studies are needed to quantify enduring learning gains and to track cumulative trajectories at scale.
Conclusion
In supervised settings, AI tutoring with a domain-specialized LLM (LearnLM) yields safety, operational, and learning outcomes at least comparable to human experts, with compelling evidence for improved transfer. This study establishes a concrete, data-driven foundation for subsequent research on the longitudinal impact, generalizability, and societal deployment of AI-driven educational interventions.

AI tutoring can safely and effectively support students: A simple explanation
What is this paper about?
The paper asks a big question: Can an AI tutor help students learn safely and well in real classrooms, not just in a lab? Tutoring one-on-one is great but expensive. The researchers tested a special AI (called LearnLM) that’s trained to teach, to see if it could help more students get good, personalized help in math classes.
What questions did the researchers ask?
The study focused on four simple questions:
- Is the AI’s teaching safe, accurate, and good quality?
- Is live, interactive tutoring better than static, pre-written hints?
- If you do get live tutoring, does AI (with a human supervising it) work as well as or better than a human tutor working alone?
- What did tutors and students think of the AI?
How did they test it?
The researchers ran a careful classroom experiment in five UK secondary schools with 165 students (ages 13–15) using the Eedi math platform.
Here’s the setup, in everyday terms:
- Random assignment (like flipping a coin to keep things fair): Students who made a mistake were either given a static hint or invited into a live chat tutoring session.
- If a student got live tutoring, there was another random step: they either worked with a human tutor alone or with LearnLM, the AI tutor, whose messages were always reviewed by a human tutor before being sent.
- Human supervision: In the AI condition, a trained tutor checked every AI message, and could approve it, tweak it, or rewrite it. The goal was safety and quality.
- Teaching style: The AI was prompted to use a Socratic approach—asking guiding questions to help students figure things out—rather than just giving answers.
- What they measured:
- Immediate fix: Did the student get the same question right on the next try?
- Misconception solved: Did they get any follow-up question in that unit right?
- Transfer: Did they get the first question in the next, related topic right (a sign of learning that sticks)?
- How they analyzed results: They used a method that estimates how likely one kind of help is better than another, rather than just saying “different” or “not different.”
Quick glossary:
- Randomized controlled trial (RCT): A fair test where people are randomly put into different groups so comparisons are unbiased.
- Socratic questions: Instead of giving the answer, the tutor asks smart questions so you discover the solution yourself.
- Transfer: Using what you learned to solve a new, related problem later.
What did they find?
Here are the main results and why they matter:
- Safety and quality were strong:
- About three out of four AI-drafted messages were approved as-is by expert tutors; many others needed only tiny edits (often just removing an emoji).
- The audit found zero harmful content and only a handful of factual mistakes out of thousands of AI messages. That’s a strong safety signal.
- Live tutoring beats static hints:
- Students did much better after interactive tutoring (whether human or AI+human) than after static hints when trying the problem again or solving follow-up questions. This confirms that real-time help matters.
- AI tutoring (with human supervision) matched or beat human-only tutoring:
- For fixing mistakes right away and resolving misconceptions, AI+human and human-only were similarly effective and both much better than static hints.
- For learning transfer to the next topic, AI+human did better: students supported by LearnLM were about 5.5 percentage points more likely to solve the first problem in the next unit than those helped by human tutors alone. This suggests the AI’s questioning may help students build understanding that carries over.
- Tutors’ experiences were positive (with useful cautions):
- Tutors praised the AI’s Socratic questions, saying they encouraged deeper thinking—and some tutors said they learned new teaching moves from the AI.
- The AI helped tutors handle more students at once, making their work feel smoother.
- Tutors still played a crucial role: they often adjusted pacing (so the AI didn’t “over-question” and frustrate students) and added social/emotional warmth and personalization (e.g., remembering a student, setting the right tone).
- Students liked tutoring:
- Students rated live tutoring as more helpful than static hints.
Why is this important?
- Access: One-on-one help is powerful but expensive. An AI that drafts strong tutoring messages—checked by a teacher—could give more students high-quality support.
- Safety: With human supervision, the AI’s help was safe and accurate in this trial.
- Learning that sticks: The AI+human approach didn’t just fix mistakes—it seemed to help students carry their understanding to new topics, which is what real learning is all about.
- Teacher support: The AI can save time and offer fresh ways to explain ideas, while teachers provide judgment, empathy, and classroom context.
What are the limits and what comes next?
- It was short-term and focused on math: We still need longer studies to see lasting effects and to test other subjects (like history or literature), which can be less clear-cut than math.
- Human oversight is key: Tutors made the AI’s guidance work for real students by moderating pace and tone. Today’s AI isn’t ready to handle the social/emotional side alone.
- Bigger studies: Future research should follow students for months, keep one type of support consistent, and include outside tests to confirm long-term gains.
Bottom line
In real UK classrooms, an AI tutor designed for teaching—and supervised by expert tutors—was safe, effective, and sometimes even better than human-only tutoring at helping students use what they learned on new problems. With teachers in the loop, AI tutoring could help bring personalized, high-quality support to many more students.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
The following gaps, limitations, and open questions remain unresolved and point to concrete directions for future research:
- Long-term learning and retention: Does AI-supported tutoring produce sustained gains over weeks or months, and does it improve performance on external, standardized assessments (e.g., GCSE), beyond immediate unit-level outcomes?
- Cumulative exposure effects: How does consistent assignment to AI vs human tutoring across an entire term affect learning trajectories, compared to session-by-session randomization that allows carryover between conditions?
- Autonomy vs supervision: What are the safety, efficacy, and failure modes of AI tutors operating with reduced or no human supervision, and what guardrails are necessary to preserve pedagogy and safety?
- Scalability and efficiency: Quantify throughput, time-on-task, latency, and cost-effectiveness (e.g., sessions per tutor per hour, cost per incremental learning gain) to determine whether supervised AI meaningfully expands capacity.
- Generalization beyond mathematics: Can AI tutoring handle subjects with ambiguous or interpretive tasks (e.g., history, literature) where misconceptions are less discrete and answers are non-binary?
- Cross-population validity: Test generalization across age groups (primary, post-16), diverse geographies and school systems, and language contexts (including higher English as an Additional Language rates), given the current cohort’s limited EAL representation and UK-only setting.
- Equity and subgroup analyses: Assess heterogeneous treatment effects by baseline ability, gender, socio-economic status, EAL status, and special educational needs to ensure AI tutoring does not widen achievement gaps.
- Tutor and school effects: Use hierarchical/multilevel models to estimate variability across tutors and schools, and to disentangle tutor-mediated effects from model effects; current analyses do not report random effects for these clusters.
- Item difficulty calibration: Incorporate item response theory (IRT) or equivalent to control for question difficulty and discrimination, particularly for the “knowledge transfer” metric based on the first question in the next unit.
- Far transfer and delayed testing: Evaluate transfer to non-adjacent topics and retention over delayed intervals (days/weeks), rather than only the immediate next unit within a sequence.
- Affective adaptivity: Measure and model student frustration, engagement, and patience in real time, and evaluate algorithms that dynamically adjust Socratic pacing versus direct instruction to prevent disengagement.
- Personalization via student history: Test whether adding past-session context and student-specific profiles (memory, rapport signals) to prompts improves engagement and outcomes while preserving privacy.
- Safety beyond constrained domains: Audit safety in open-ended tasks, longer dialogues, and adversarial scenarios; the current low-risk math setting with expert supervision may understate real-world risks.
- Pedagogical quality auditing: Go beyond edit-distance metrics and apply expert rubric-based semantic evaluations to detect subtle misguidance, incomplete explanations, or off-target questioning.
- Model and prompt ablations: Replicate with updated models (e.g., Gemini 2.5 Pro) and non-fine-tuned LLMs to isolate the contribution of pedagogy-specific fine-tuning and prompt design to observed effects.
- Reproducibility and transparency: Enable third-party replication with pre-registration, shared analysis plans, anonymized data/message corpora (where feasible), and independent auditing to mitigate potential conflicts of interest.
- Operational metrics: Rigorously measure tutor workload distribution, switching costs between supervision and direct tutoring, queue times, and session concurrency under classroom conditions.
- Tutor professional development: Quantify whether supervising AI produces durable improvements in tutors’ pedagogy, and estimate contamination effects when tutors apply AI-derived practices in human-only sessions.
- Student attitudes and agency: Systematically study students’ trust, perceived helpfulness, autonomy, and metacognitive outcomes when interacting with AI tutors, beyond small-sample post-trial surveys.
- Privacy and safety trade-offs: Investigate how storing session history and personalization data affects child safety, privacy, and regulatory compliance in school deployments.
- Topic-specific performance: Map AI vs human advantages across specific misconception categories and math topics to identify where AI guidance is most/least effective.
- Socratic pacing optimization: Develop and evaluate policies (e.g., reinforcement learning from human feedback) that trigger timely pivots from inquiry to instruction when affective signals indicate frustration.
- Tone and persona calibration: Test how stylistic choices (e.g., emoji use, formality, warmth) impact engagement and performance, and codify style guidelines for age-appropriate communication.
- Infrastructure constraints: Examine how latency, device availability, and connectivity affect tutoring effectiveness and student experience in varied school settings.
- Teacher adoption and role design: Study educators’ acceptance, training requirements, workload impacts, and the organizational changes needed to integrate AI tutoring sustainably.
- Platform dependence: Validate results on other platforms (including those using open-response items) to reduce dependence on multiple-choice, misconception-aligned workflows like Eedi’s.
- Selection effects: Analyze outcomes for students who do not trigger interventions (i.e., answer correctly on first attempt) and evaluate proactive AI support versus remedial-only triggering.
- Carryover and contamination quantification: Design studies that prevent or explicitly measure cross-condition learning among tutors and students to obtain cleaner causal estimates.
- Statistical power and stability: Conduct larger, pre-registered trials with planned power analyses to confirm the observed 5.5 percentage-point transfer advantage and assess effect stability across cohorts.
