In the era of intelligence, the integration of artificial intelligence into the educational system has catalyzed transformations in the field of education, shaping the practical vision of smart education. However, the conflict between emerging intelligent technologies and traditional educational ethics remains an unavoidable and pressing issue. This paper provides a detailed analysis of the ethical dilemmas surrounding technology in the context of smart education, including the loss of the ethical space for teacherstudent dialogue and the resulting emotional alienation, the decline in subjective intelligent thinking and the rise in algorithmic prisoners, the increased risk of resource allocation deviation, and the existence of technology in the form of bias, among other issues. It aims to promote the high-quality development of smart education and better serve the construction of a modern socialist China by adopting countermeasures to solve the contradictions of technological ethics.
