【中文摘要】：
基于社会比较理论，学习者模型可视化不但有助于自我改进、强化及评价，具有元认知和自我调节学习价值，而且还能内化同伴的学习知识，激发学习动机，提升自我效能感，促进高阶思维发展。以美国匹兹堡大学的MasteryGrids自适应学习系统为例，利用问卷调查法，从有用性、感知性等方面对学习者模型可视化进行认同感分析，并采用曼惠特尼U检验分析方法和实验控制组对其效能进行评测。结果表明，学习者模型可视化所具有的特性验证了期待和信仰，可为在线个性化学习环境设计提供理论依据，尤其是解决学生持续学习能力差和低完课率等实际问题，确保在线教育的成功实施。
【英文摘要】：
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.
