Based on the social comparison theory, the visualization of learner model not only contributes to self-improvement, reinforcement and evaluation, but also has the value of metacognition andself-regulated learning. In addition, it can internalize the learning knowledge of peers, stimulate the learning motivation, enhance the sense of self-efficacy, and promote the development of high-order thinking. Taking the MasteryGrids adaptive learning system of the university of Pittsburgh in America as an example, this study adopts questionnaire survey to analyze the identification of the visualization of the learner model from usefulness, perception and other aspects, and uses Whitney U test and experimental control group to evaluate its efficiency. The results show that the characteristics of the visualization of the learner model verify the expectation and belief, which can provide a theoretical basis for the design of online personalized learning environment, especially for solving practical problems such as students' poor continuous learning ability and low completion rate to ensure the successful implementation of online education.
