一句话总结

对2020–2025年多语言MOOC中的合成媒体进行范围性综述,考察深度伪造教师、教学影响、伦理/政策问题,并提出一个治理框架,以在不取代人类教学的前提下将合成媒体负责任地融入其中。

ABSTRACT

In recent years, synthetic media from deepfake videos have emerged as a new interesting technology, whether that refers to cloned voices, multilingual translation models, or more recent applications of avatar tutors into higher education. As such, these technologies are rapidly becoming part of the multilingual distance learning model and, more recently, MOOCs worldwide. This article is a scoping review that focuses on recent international literature published between 2020 and 2025 to explore the usage of deepfake and synthetic media tools and methods in multilingual MOOC content and assess the influence of these technologies on social presence and participation. Similarly, we focus on ethical and political issues that are closely connected with the adaptation of these technologies, and upon analysing educational technology and policy documents, such as UNESCO's Guidelines and the EU AI Act, we pinpoint that the use of synthetic avatars and AI-generated videos can diminish production costs and assist multilingual learning. Evidently, concerns arise regarding authenticity, privacy, and the shifting nature of the teacher-learner relationship that are thoroughly discussed. As a result, the technical merit of this paper is the proposal of a policy framework that, in an effort to address these issues, focuses on transparency, responsible governance, and AI literacy. The goal is not to replace human instruction but to integrate synthetic media in ways that strengthen pedagogical design, safeguard rights, and ensure that multilingual MOOCs become more interesting and inclusive rather than more automated robotic processes and unequal

研究动机与目标
