调研发现，很多线上协作学习的效果并不理想，基于MOOC的协作学习经常存在完课率低、动机难以持续保持的问题。文章从人的社会属性和社会性知识建构的视角出发，借助实证性研究范式探索了群体感知效应对线上协作学习的影响，针对线上学习中普遍存在的交互质量不佳和线上自主学习持久性不强等问题，分别从认知感知效应、社会感知效应、行为感知效应3个维度提出了有效的干预策略，形成了群体感知效应模型。最后，以3个同质教学班为研究对象，开展了5轮教学实践，论证了群体感知效应模型的有效性。研究证实：良好的群体感知效应模型能够提升线上交互质量、保持学习动机并降低线上自主学习中的孤寂感。
【英文摘要】：
It is found that many collaborative online learning have been confronted with the problems such as low completion rate and difficulty in maintaining learners' motivation. From the perspective of man's social attributes and social knowledge construction, this paper explores the impact of group perception on online collaborative learning with the help of empirical research paradigm. In view of the problems in online learning, such as the poor quality of interaction and the weak durability of online autonomous learning, this paper proposes effective intervention strategies from three dimensions of cognitive perception effect, social perception effect and behavioral perception effect and forms the group perception effect model. Finally, the effectiveness of the group perception effect model is demonstrated by 5 rounds of teaching practice in 3 homogeneous classes. The research proves that a good group perception effect model can improve the quality of online interaction, maintain learning motivation reduce the sense of loneliness in online autonomous learning.
