【摘要】 为帮助学习者掌握自适应学习系统为学习者所定义的个性特征和学习信息,设计并开发了开放性学习者模型MindOLM。MindOLM采用思维导图可视化形式将学习者模型中课程知识状态呈现给学习者,帮助学习者了解、查看自己的学习进展,以及章、节、知识点之间的关联关系,并引发学习者元认知学习体验。在实证研究方面,通过实验研究法、问卷调查和面对面访谈等方式收集数据,结果表明:MindOLM能引发学习者在学习规划和自我反思两个方面的元认知学习体验; MindOLM能很好地表示学习者学习进展和知识水平;学习者对MindOLM在有用性、易用性和满意度3个方面都表现出较高的认可度。更多还原

【Abstract】 In order to help learners master their individual characteristics and learning information defined by adaptive learning system,an open learner moder,called as MindOLM,has been designed and developed.MindOLM adopts mind map to release curriculum knowledge states in learner model to the learner,helping the learner to understand and view his/her learning progress,and the relationships among chapter,section and knowledge point,and inducing his/her meta-cognitive learning experience. In the empirical research,evaluation data was collected through experimental research method,questionnaire survey and face-to-face interviews. The results show that: 1) MindOLM can induces meta-cognitive learning experience on learning planning and self reflection; 2) MindOLM can presents their learning progress and knowledge level; 3) learners have shown strong acceptance to usability,usefulness,and satisfaction with MindOLM.更多还原
