This study aimed to examine the impact of GenAI on the learning outcomes of K-12 and higher education students, and explore the moderating factors influencing this impact. A meta-analysis of 49 articles showed that the mean effect sizes of GenAIon students’ learning achievement and learning motivation were 0.857 and 0.803, respectively, indicating a positive impact of GenAI on education. However, this effect varied according to moderators, including education level, subject classification, GenAI interface, GenAI development, interaction approaches, and experimentation time, which enhanced the impact of GenAI on education. Specifically, GenAI had a greater impact on the academic performance of higher education students, and students interacted more effectively with GenAI using text than with mixed media, such as images or audio. Although GenAI has a novel effect on students’ learning motivation, the effect size decreases over time. These findings provide empirical support for the beneficial effects of GenAI on education and offer insights for optimizing its use in teaching practices.  \n1 South China Normal University, China  \nCorresponding Author:  \nXiaoyong Hu, Institute of Artificial Intelligence in Education, South China Normal University, 55 Zhongshan Avenue West, Tianhe District, Guangzhou 510631, China.  \nEmail: [huxiaoy@m.scnu.edu.cn](huxiaoy@m.scnu.edu.cn)  \nKeywords  \ngenerative AI, learning outcomes, learning achievement, learning motivation, metaanalysis  \nIntroduction  \nIn recent years, there have been rapid advancements in the development of artificial intelligence (AI) . Notably, the launch of ChatGPT on November 30, 2022, marked asignificant milestone in the history of AI development (Alier et al., 2024) . ChatGPT’s adaptability, with its ability to learn from both structured and unstructured data, makes it a highly versatile conversational AI tool, and has thus been attracting increasing attention for its educational applications (Jauhiainen & Guerra, 2023) . With the widespread use of generative artificial intelligence (GenAI) products in education, tools such as ChatGPT show great potential in teaching practice, while also fostering in-depth exploration of educational models and methodologies within the academic community. GenAI has implications for both teaching and assessment (Bower et al., 2024), prompting researchers to consider teaching strategies that integrate GenAI (Kong & Yang, 2024) .  \nResearchers are increasingly examining the impact of GenAI applications in specific domains and environments. For instance, Baha et al. (2023) found that chatbots can significantly enhance the learning experience for middle school students. However, Qureshi (2023) observed that sophomore students ’ performance was hindered by inaccuracies and inconsistencies in code submissions created with ChatGPT in programming contexts. Kosar et al. (2024) reported that ChatGPT use did not affect the programming performance of first-year undergraduate students. In other words, there is no consensus on the effectiveness of generative AI in education. Meta-analyses, which aggregate data from multiple studies, enable researchers to measure overall effect sizes, providing more robust and persuasive insights into outcomes.
