  • 1. A New Form of Learning Resource in u-Learning Environmen —A Brief Introduction to Learning Cell Xianmin Yang PhD Candidate in BNU Email: yangxianmin8888@163.com Ubiquitous Learning Team, Beijing Normal University
  • 2. Background
  • 3. Table of Contents一.Background二.Design conception三.Concept and Model四.Prototype system五.Application scenarios六.Ongoing exploration
  • 4. New emerging technologies 1Virtual Reality Things of Internet Pervasive ComputingSemantic Web Clound Computing
  • 5. New emerging technologies 1 The world is changing! Our life, work, learning….everything is in the tide of changing!
  • 6. Popular learning theories 2 Social Constructivism Connectivism Distributed Cognition Situated Cognition …..
  • 7. New characteristics in learning 2 ubiquitous Learning social informal connective situational adaptive Learning Technology theory
  • 8. Next generation of e-Learning: 3 U-Learning Next phase of e-Learning development 5A Learning (anyone, anywhere, anytime, any device, any learning resource) Key features  Ubiquitous  Informal  Situated  Social  Context-aware  Distributed cognition
  • 9. Progresses of Learning Resource Sharing Technologies 3
  • 10. Deficiencies of Current Learning Technologies 3 Born in Web1.0 era Only supports one-way information communication More focus on formal learning, less on informal learning
  • 11. Deficiencies of Current Learning Technologies 3 Emphasize learning resources and activities sharing in a close structure  Ignores the continuous updating of learning resources  Ignores dynamic and generative connection of learning resources  Ignores building up dynamic relationships between learners and teachers with learning resources
  • 12. Proposal of Learning Cell Year 2008 Prof. Yu Shenqquan Propose Learning CellThe organizational model and key technologies of u-Learning resource
  • 13. Design conception
  • 14. Design conception of LC 1 一、Supporting a whole learning flow Objective Learning Learning instruction content activities Tool Base: BBS Interactive Q&A Online survey Online quiz Practice Assessment Subject tool ……
  • 15. Design conception of LC 2 二、Emphasize the connections between resources and users
  • 16. Design conception of LC 3 三、Open APIs to link external learning ecosystem
  • 17. Design conception of LC 4 四、Make learning resources evolve orderly (内容+人际网+外部资源+外 部链接+过程性信息) 添加外部链接 版本4 附加人际网 版本3 附加人际网 编辑内容 版本2 生产 发表评论 做批注 版本1 嵌入Rss资源
  • 18. Design conception of LC 5 五、Persist valuable generating information Learning Resource is Not Presetting, But Generating!
  • 19. Concept and model
  • 20. What is Learning Cell? 1 A new kind of learning resource designed for u-Learning Make a big improvement of Learning Object  Supports sharing of the valuable generative information  Supports sharing of social cognitive network  Can realize self-evolution  Keep a small granularity and more intelligent
  • 21. Conceptual model of LC 2
  • 22. Information model of LC 3
  • 23. Runtime environment of LC 4
  • 24. u-Learning process Based on LC 5
  • 25. Prototype System
  • 26. 实际依托项目 1 Funded Natural Science Foundation of China Website: http://lcell.bnu.edu.cn
  • 27. Architecture 2
  • 28. Unique features 3一.Resource organization based on knowledge ontology 知识模型 知识实例 知识本体 资源实体
  • 29. Unique features 3 本体标注器 新资源 附加本体 自动标注 手工校对 本体抽取 应用统计 应用统计 进入 本体精炼 自动提取 知识本体 学习资源空间 学科知识本体编辑 语文 计算机 物理编辑 小说 人物 阅读 CPU 程序 硬盘 重力 阻力 速度 作文 识字.. 有向图 软件.. 加速度 定律.. …… 扩展 通用学科知识本体 (概念、事实、原理、程序性知识、复合性知识)

  • 34. Unique features 3六、Transformation Between SCORM and LC
  • 35. Unique features 3七、Dynamic metadata searching•Reference the search method of Googlebase and Freebase•Realize more precise retrieval of learning resource
  • 36. Unique features 3八、Tag Navigator and Tag cluster
  • 37. Unique features 3八、Tag Navigator and Tag cluster
  • 38. Unique features 3八、Tag Navigator and Tag cluster
  • 39. Application Scenarios
  • 40.  Resources library construction Publishment of digital resources Knowledge management organizational learning For more information:  http://lcell.bnu.edu.cn/help/FAQ.jsp#four_1
  • 41. Ongoing exploration
  • 42. Learning resource evolution 1  How to make LC evolve orderly? Web1.0: closed, evolve less HOW? Continually, orderly evolutionWeb2.0: open, evolve in disorder
  • 43. Adaptive recommendation of LC 2 How to recommend LCs to users adaptively? Adaptively Personally User-centered Learning Environment
  • 44. u-Learning model based on LC 3 How to implement multidimensional learning based on learning? How to design and verify the learning effects of learning models based on LC?
  • 45. Automatic Social Network Construction 4 How to construct social network dynamically through mining all kinds of learning process information?
  • 46. Self-adaption of Learning content 5 on multi-devices How to display correctly learning contents on different learning devices?
