在数字化时代背景下,微课作为一种在线教学资源,凭借其灵活性和高效性,满足了快节奏社会中学习者对知识碎片化的需求;然而,传统微课设计与制作流程复杂且耗时,难以适应快速发展的教育需求。聚焦GenAI技术,提出了一种基于“人机协作”的微课设计与制作模式,从文本生成、素材创作、虚拟数字人应用及音视频合成等核心技术入手,结合实践案例探讨其在微课制作中的创新应用。研究表明,GenAI技术能提升微课制作的效率,丰富微课内容,但同时面临技术门槛以及教学互动的局限性等问题。

In the context of the digital age, micro-course, as an online teaching resource, has met the demand for fragmented knowledge in a fast-paced society with its flexibility and efficiency. However, the traditional design and production process of micro-course is complex and time-consuming, making it difficult to adapt to the rapidly developing educational needs. This paper focuses on GenAI technology and proposes a "human-machine collaboration" based micro-course design and production model. Starting from core technologies such as text generation, material creation, application of virtual digital human, and audio-video synthesis, it explores their innovative applications in micro-course production through practical cases. Research shows that GenAI technology can enhance the efficiency of micro-course production and enrich the content of micro-course, but it also faces problems such as technical barriers and limitations in teaching interaction.
