Socratic and dialogic tutoring: research in plain words
Research on tutoring that asks guiding questions and gives hints instead of handing over solutions, including AI that drafts those questions.

Unrestricted ChatGPT help raised practice scores but lowered exam scores
Hamsa Bastani et al. (2025) · Preregistered randomized controlled trial (field experiment) · Peer-reviewed
In a high school in Turkey, students who practised maths with a plain ChatGPT-style GPT-4 assistant did much better during practice, then scored 17% lower than students without AI when they sat a test on their own. A second version with teacher-written prompts that gave hints instead of solutions avoided that drop, but did not beat the no-AI group on the test either.
Supervised AI tutoring matched human tutors in UK maths classrooms
LearnLM Team (Google) et al. (2025) · Exploratory randomized controlled trial · Preprint (not peer-reviewed at the time of summary)
In five UK secondary schools, pupils who got chat tutoring drafted by Google's LearnLM model, with every message checked by an expert tutor, did at least as well as pupils tutored by humans alone, and were 5.5 percentage points more likely to solve new problems on later topics. Tutors approved most AI drafts with little or no editing.
An AI coach for human tutors raised topic mastery, most for weaker tutors
Rose Wang et al. (2024) · Preregistered randomized controlled trial · Working paper / preprint
Giving human tutors an AI tool that suggests expert-style next moves made their students 4 percentage points more likely to master a topic, and 9 points more likely for students of lower-rated tutors. Tutors with the tool asked more guiding questions and gave away answers less often. End-of-year test scores did not improve significantly.
Prompting learners to explain to themselves helps: a meta-analysis of 64 reports
Kiran Bisra et al. (2018) · Meta-analysis · Peer-reviewed
Across 69 effect sizes from 64 research reports, learners who were prompted to explain the material to themselves while studying or solving problems learned more than those who weren't. The average benefit was medium-sized and showed up across many subjects and settings.
