As a product of the deep integration of information technology and education, educational informatization has become the core driving force for promoting educational reform and development. However, current research on educational informatization mostly focuses on the application of technology. While the exploration of its essence is still insufficient. This article starts from the perspective of education and deeply analyzes the core connotation of educational informatization, revealing its essential characteristics in dimensions such as educational goals, teaching processes, and teacher-student relationships; By analyzing the potential application of educational informatization in promoting personalized learning, promoting educational equity, and reconstructing educational evaluation, combined with the current practical challenges such as the disconnect between technology and educational concepts, insufficient teacher information literacy, and imbalanced regional development, this paper proposes development strategies led by educational theory, strengthening teacher construction, and building collaborative mechanisms, aiming to provide theoretical support and practical paths for the deep promotion of educational informatization.
