摘要

The emergence of artificial intelligence (AI) has heightened interest in personalizing computer assisted learning (CAL) programs to tailor their instruction to individual students. Despite the proliferation of AI-driven CAL programs, evidence for their effectiveness remains limited. We present findings from a field experiment in rural China examining whether an AI-driven personalized CAL program improves student achievement. We randomly assign 8647 students from 315 primary school classes to one of three treatment arms: (i) AI-CAL, (ii) non-personalized CAL (active control), and (iii) non-CAL educational activities (pure control). Results indicate that AI-CAL does not significantly improve achievement, with estimates precise enough to rule out non-trivial positive effects. This finding holds across the difficulty of assessment items and across the baseline achievement of students. If anything, AI-CAL might be less effective than non-personalized CAL for students in the middle tercile of baseline achievement. These findings call for caution when scaling AI-driven educational technologies.

中文摘要

人工智能的出现激发了人们对个性化计算机辅助学习(CAL)项目的更大兴趣,以期根据学生个体情况调整教学。尽管人工智能驱动的CAL项目不断增多,但其有效性的证据仍然有限。我们呈现了一项在中国农村开展的实地实验研究结果,考察人工智能驱动的个性化CAL项目是否能提高学生成绩。我们将来自315个小学班级的8647名学生随机分配到三种处理组之一:(i)AI-CAL,(ii)非个性化CAL(主动对照),以及(iii)非CAL教育活动(纯对照)。结果表明,AI-CAL并未显著提高成绩,估计结果足够精确,可以排除非平凡的正向效应。这一发现适用于不同难度的评估题目以及不同基线成绩的学生。如果说有什么不同的话,对于基线成绩处于中间三分之一的学生而言,AI-CAL可能不如非个性化CAL有效。这些发现呼吁在推广人工智能驱动的教育技术时保持谨慎。
