The development of information technology has changed people's learning methods. Fragmented learning, as an informal learning method, has become an important way to accept new knowledge and learn new technologies. Through analyzing the connotation, characteristics, and advantages and disadvantages of fragmented learning, this paper came up with reasonable recommendations for fragmented learning. To truly become systematic and holistic knowledge, fragmented knowledge must be explored, understood, integrated and internalized. This paper is expected to play an important guiding role in building a lifelong learning society.
