We conducted a randomized experiment on educational informatization in impoverished regions of western China, leveraging information technology to deliver high-quality instructional videos to rural primary school students. The study aimed to evaluate the impact of this intervention on student development, with a focus on both short-term dynamic effects and long-term outcomes over a three-year period. The experiment was designed with three distinct treatment groups: one receiving online education, another using recorded video lessons, and a third relying on traditional teacher-led instruction. We specifically examined how the effects of educational informatization varied across different student populations, subjects, and grades, as well as how it interacted with traditional teachers and teaching methods. The analysis establishes substantial heterogeneity in the effects of educational informatization. Additionally, we employed machine learning techniques to explore heterogeneity, seeking to investigate context-specific and personalized strategies for optimizing the effectiveness of educational informatization.
