    选题意义:近几年来,由于国内经济发展速度减缓,有效需求不足,财政和货币政策难以启动消费市场,大多数商品呈现供过于求或供求平衡的状况,于是,如何扩大内需,拉动经济增长,成了政府经济部门及经济学者广泛探讨的话题。与此同时,教育市场却供不应求,供需矛盾因教育经费投入不足而长期无法得到解决。特别是随着人们对教育的日益重视及对知识需求的不断提高,这一矛盾越发突出,教育已日益成为社会关注的热点。理论界对此进行了深入的探讨,可以说,教育产业问题不仅是涉及到教育基本性质的理论问题,也是关系到当前教育政策及今后教育可持续健康发展的重大现实问题。 论文重点:本文尝试从产业经济学的角度,对高等教育的产业属性进行分...学位:经济学硕士院系专业:经济学院经济研究所_产业经济学学号:19981601

    [[abstract]]Many studies have indicated interest in learning digital game-based learning has become an effective teaching strategies and teaching tools. In the past decades, empirical studies showed that digital game-based can enhance learners’ cognitive, affective and skills as learning objectives. Current research focused on how the new technology integrated into teaching strategies and teaching interest in digital learning system for the learners with different back-grounds and characteristics. Many studies have shown that learning process in which the flow experience for learning has a significant impact. In addition, re-searches have also pointed out that the multi-media materials presentation and system interface design will affect the learning of learners carrying out the ex-ternal and the proliferation of cognitive load. The excessive amount of cogni-tive load for learning will have a negative impact. Research indicates that learn-er’s prior knowledge and learning strategies to influence the flow of experience in the heart of learners, learning outcomes and cognitive load of the main fac-tors. Digital game-based system design includes the design of teaching content and system interface design. Previous studies have mostly concentrated on teaching the content of the application of the principles of instructional design. According to previous studies, the interface design of learning system will af-fect learner's learning, motivation, satisfaction, learning efficiency, and quality of interaction and so on. Therefore, the digital learning system interface design became an important factor toward learning. There are many studies have shown the system visibility, cognitive support, efficiency, user control, joyful-ness are the important aspects of learning system design. Some scholars have pointed out that the learning system in the interface design should not be as high as possible on each aspect. In other words, the system interface design and flow experience, cognitive load and the relationship between the effectiveness of learning is not a simple linear correlation curve but curvilinear correlations. But very little empirical research has done about what extent is the "moderate" or "best" design. In addition, for learners of different backgrounds should have different design. Therefore, the purpose of this study were to explore digital game-based mobile learning system visibility, cognitive support, efficiency, us-er-controlled, and joyfulness for different prior knowledge learners’ flow expe-rience, cognitive load and learning achievement.[[sponsorship]]HCI International[[conferencetype]]國際[[conferencedate]]20140622~20140627[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]Creta Maris, Heraklion, Crete, Greec
