Abstract: At present, online learning has a great impact on the traditional learning mode, so it is urgent to study a new learning mode based on online learning. Compared with the feedback mechanism of "class -exercises" of liberal arts and science majors, students of art design specialty have different forms of imagination or association in design and creation when they think about the same knowledge point, which means that the best learning activities are suitable and practice as one-to-one interaction. The offline learning of art design specialty, which is intuitive and instant, and the learning interaction effect is good. Taking this as a reference, the online learning feedback mechanism should also be intuitive and instant. Therefore, online learning can be divided into output mechanism and feedback mechanism, in which the output mechanism focuses on learning methods and learning content, while the feedback mechanism focuses on learning feedback. Based on the analysis and summary of existing cases, this paper will further combine the characteristics of art design specialty, and put forward the corresponding optimization path.

Key words: Art design specialty, Online learning, Feedback mechanism
