虚拟讲师在线课程教学新技术探索与实践

Exploration and Practice of New Technologies of Online Course Teaching by Virtual Lecturer

针对当前国内在线课程建设普遍存在的制作成本高、更新推广慢等现实问题,文章将深度学习、自然语言处理等最新人工智能技术与在线课程有机融合,提出虚拟讲师的定义、内涵、技术框架,并开发一款面向在线教学的虚拟讲师软件系统,来模拟教师讲课的教学场景。在此基础上,提出基于该系统的课件制作流程,并运用于《人工智能引论》慕课教学实践。通过探索基于虚拟讲师技术的在线课程创新教学模式,有效推动国内在线课程可持续发展。

To solve the issues of high production cost,slow update and promotion of online courses,this paper integrates the latest artificial intelligence technologies such as deep learning and natural language processing with online courses,and consequently proposes the definition,connotation and technical framework of virtual lecturer.It develops a virtual lecturer software system for online teaching to simulate the teaching scene.On this basis,it puts forward the courseware making process based on this system and applies it to the MOOC teaching practice of“Introduction to Artificial Intelligence”.By exploring the innovative teaching mode of online course based on the technology of virtual lecturer,it can effectively promote the sustainable development of online courses in China.
