讲座题目：AI-Assisted Learning, Academic Achievement, and Beyond: Experimental Evidence from Middle School Students in China
内容简介：By distributing Artificial Intelligence-powered learning laptops (AI laptops, hereafter) to randomly selected classes for studying Math in 53 middle schools across 18 Chinese provinces, this paper comprehensively assesses the effects of AI-Assisted Learning (AAL), with a particular focus on the academic achievement of students. We find that students equipped with AI laptops scored significantly higher in post-treatment exams, a finding consistent with results from the matched sample based on the propensity score of treatment. We also uncover heterogeneity in effects with policy implications that favor educational equity: the impact is notably more pronounced in under-developed areas, cities with lower educational fiscal expenditure per capita, among students with a weaker learning foundation, and for girls. Additionally, we present direct evidence of positive associations between exam performance improvements and targeted exercises using the AI laptop, suggesting the self-adaptive feature of AI laptops as a pivotal mechanism. Lastly, we highlight potential spillover effects of using AI laptops on academic performance in other subjects, learning interests, time allocation, and self-development.
