A Meta-Analysis and Systematic Review of the Effect of Chatbot Technology Use in Sustainable Education
Open accessAbstract
The development of artificial intelligence in recent years has promoted the use of chatbot technology in sustainable education. Many studies examined the effect of chatbots on learning outcomes. However, scant studies summarized the effectiveness of chatbots in education. The aim of the study is to investigate the effect of chatbot-assisted learning on various components and how different moderator variables influenced the effectiveness. This study, through a meta-analysis, reviewed 32 empirical studies with 2201 participants published between 2010 and 2022. The results showed that chatbot technology exerted a medium-to-high effect on overall learning outcomes regardless of moderator variables, i.e., intervention duration, chatbot roles, and learning content. In terms of learning components, chatbots could significantly improve explicit reasoning, learning achievement, knowledge retention, and learning interest despite negative findings in critical thinking, learning engagement, and motivation. Future research could expand chatbot research by including different learning components.

TL;DR
This meta-analysis and systematic review examined 32 empirical studies with 2201 participants and found that chatbot technology had a medium-to-large positive overall effect on learning outcomes (d = 0.789). Effects were significant for explicit reasoning, learning achievement, knowledge retention, and learning interest, but not for critical thinking, learning engagement, or motivation.
Key findings
- The overall effect size of chatbot use in education was d = 0.789 (95% CI [0.593, 0.985], p < 0.001), described as medium-to-large.
- Chatbots significantly improved explicit reasoning (d = 1.190, p < 0.001), learning achievement (d = 1.033, p < 0.001), knowledge retention (d = 0.691, p = 0.022), and learning interest (d = 0.842, p = 0.041).
- Chatbots did not significantly improve critical thinking (d = 0.690, p = 0.144), learning engagement (d = 0.147, p = 0.114), or learning motivation (d = 0.409, p = 0.114).
- Moderator analyses found no statistically significant differences by intervention duration, chatbot roles, or learning content (all p > 0.05), though subgroup effect sizes varied.
Methods
- The authors conducted a PRISMA-guided meta-analysis and systematic review, searching major databases including Web of Science, Wiley Online Library, Springer Link, Taylor & Francis Online, Elsevier ScienceDirect, and Google Scholar on 3 September 2022.
- They included 32 empirical studies published between 2010 and 2022 with 2201 participants, calculating 76 effect sizes using Cohen’s d; studies needed experimental/control comparisons and sufficient statistics.
- Analyses used Stata MP/14.0, with publication-bias checks (funnel plot, Begg’s test, Egger’s test), heterogeneity tests (I²), sensitivity analysis, and meta-regression for intervention duration, chatbot roles, and learning content.
Limitations
- The paper states that only studies written in English were included, that only three moderator variables were examined, and that unpublished studies with insignificant results may still influence the findings despite no detected publication bias.
- Evident from the text: several outcome domains had high heterogeneity (e.g., critical thinking I² = 92.8%, motivation I² = 93.2%, overall I² = 87.8%), and some categories had very few studies, limiting moderator conclusions.

The included studies had sufficient statistical power to detect effects on learning engagement and motivation.
“However, significant differences in learning engagement and motivation were not found between the chatbot-based condition and the control condition.”

In the citing paper
“However, the study also highlights the constraints of ChatGPT, particularly its potential to limit creativity and critical thinking, which aligns with the findings of Deng and Yu (2023) but contrasts with Abramson's (2023) view that AI can enhance creativity by offloading routine tasks.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
