Knowledge and learning in a fragment age

  1. 1. Department of psychology and behavioral sciences<br />Knowledge & Learning for a Better World<br />Knowledge and learning in a fragment age<br />SHENTU Teng<br />August , 2010 Hangzhou, China<br />
  2. 2. The incoming contents<br />2<br />
  3. 3. It’s not just a tool<br />The power of Internet is underrated<br />Most people may still think Internet as a tool, just like radio or TV, that's true indeed 10 years ago.<br />But with the arrival of Web2.0 and the incoming Web3.0, the Internet shows himself as the dawn of a new age, the fragment age.<br />Then what's that has anything to do with knowledge?<br />3<br />
  4. 4. The Internet and Writing<br />Let's roll back to 2400 years ago, when the characters and writing just came out. The Socrates and his apprentices Plato look down to the writing.<br />The writing is toy for children, the speech is wisdom of adults.<br />4<br />
  5. 5. The Internet and Writing<br />Time changes, and the wise can be wrong.<br />The knowledge for the first time can break through the limit of Time, and become permanent treasures of human beings. <br />That's how we stand on the shoulders of giants.<br />5<br />
  6. 6. The Internet and Writing<br />Would it be possible that the mighty Internet help us break through the spatial limit?<br />If you prefer it's YES, then let's move on.<br />6<br />
  7. 7. Knowledge and Learning<br />What is knowledge?<br />We often forget the information as knowledge.<br />The information flows on Internet is the same as the knowledge bear in our mind.<br />Can we learn from Internet? <br /><ul><li>Expertise and skills
  8. 8. Facts and information
  9. 9. Awareness or familiarity </li></ul>BUT<br />Defined by the Oxford English Dictionary<br />7<br />
  10. 10. Knowledge and Learning<br />How to dodge a snakebite<br />8<br />
  11. 11. The incoming contents<br />First, introduction of the connectivism as a learning theory.<br />Then, how Internet make it possible to learn in this way.<br />At last, we will try to dodge the snakebite. <br />9<br />
  12. 12. Connectivism<br />Connection matters<br />From Wikipedia<br />Connectivism is a learning theory used in computer science which is based on the premise that knowledge exists in the world rather than simply in the head of an individual.<br />We all know our brain is just a huge network of neurons. But your computer seems not work in that way. The idea of create an artificial network to compute leads to connectionism.<br />10<br />
  13. 13. Different program models<br />The traditional program model<br />The If-then model<br />Like a guide book<br /><ul><li>The possible problem and solution is coded by programmer.
  14. 14. The program is preset.
  15. 15. The knowledge is beard in mind of programmer, who write the program to make it explicit.</li></ul>if …<br /> then … ; if …<br /> then … ;<br />if …<br /> then … ;<br />11<br />
  16. 16. Different program models<br />The connectionism program model<br />Like a student<br />The network model<br /><ul><li>The programmer build up network without any code.(a blank network)
  17. 17. Train the network with some input and expected output.* *(Learning)
  18. 18. Solve new problems in some degree
  19. 19. The knowledge is beard in the network and implicit</li></ul>Answer<br />Expected output<br />Solutions<br />Training input<br />Problem<br />*The training process will change the connection between nodes. e.g. enhance the right path.<br />12<br />
  20. 20. Different learning approach<br />Taking a course or reading a book is like install a software. Maybe you only need one simple function, but the programmer doesn’t know what the function is, so most of the IFs are just in case.<br />13<br />
  21. 21. Different learning approach<br />But connectionism take a different approach, you can always get the answer of the problems in the domain where the network has trained. The answer may be not good enough, but the network learns at the same time, so next time, it would be better.<br />14<br />
  22. 22. The society as a network<br />What if we see the entire society as a network and every individual as a node<br />Problem<br />Answer<br />15<br />
  23. 23. It’s happening in everyday life<br />You won’t be the first one who meet such kind of problem, there’re someone who know how to deal with it. But,<br />Can you find them? <br />16<br />
  24. 24. Internet for the rescue<br />Thanks to Internet, now the people we meet in one day can be more than that of Socrates’ whole life.<br />On what level has the world changed?<br />Especially after the buzz word Web2.0 comes out.<br />17<br />
  25. 25. How Internet shape the world<br />Be visible online<br />Web2.0 technologies make the Internet user friendly, so the content is user generated, which means more people are visible online.<br />18<br />
  26. 26. How Internet shape the world<br />Be short and shorter<br />The content is short fragment rather than a chunk of systematic knowledge.<br />A Page<br />A Blog<br />A Tweet<br />19<br />
  27. 27. How Internet shape the world<br />Be fast and faster<br />Therefore information spreads fast in this network. <br />One hour after the news of Jackson's death hits the internet, the first mainstream news source publishes a confirmation article.<br />20<br />
  28. 28. How Internet shape the world<br />Information reorganization<br />What’s google’s content? <br />More than 80% content of this page is taken from other website.<br />Google just collects information and tell you where it is.<br />21<br />
  29. 29. What would the learning be like then?<br />22<br />
  30. 30. Still remember the case?<br />How to dodge a snakebite<br />23<br />
  31. 31. In Web1.0 or before<br />Sorry, good luck next time, find a website about jungle exploring before you are in danger.<br />24<br />
  32. 32. In Web2.0<br />This is what you get NOW, You may find a Blog about how to dodge it, or a Video clip of a real example.<br />But still sorry, before you click and see what’s that, you have already been bitten.<br />If there’s a “snake bite dodging club” on Internet, things may slightly different. Because the experts there know where to find the guide, and collect it, so it’s faster to get the really helpful information.<br />25<br />
  33. 33. In Web3.0<br />In Web3.0, the Internet is a Semantic Network, which means the internet can understand what you want. So it’s like asking a Mr. Known-all rather than searching.<br />Congratulations, now you dodged a snake bite successfully. Why not write down your experience and share with your friends?<br />26<br />
  34. 34. It may take decades for the Web3.0 to come, but there’re something we can do now to improve the environment for learning.<br />27<br />
  35. 35. What to do<br />Tips for a better learning environment<br />More Resource<br />Encourage more people to contribute to Internet and share knowledge.<br />28<br />
  36. 36. What to do<br />Tips for a better learning environment<br />More Problem-based<br />Change the form of knowledge on Internet. Tear it into fragments and reorganize them according to problem.<br />29<br />
  37. 37. What to do<br />Tips for a better learning environment<br />More Professional Social-Network<br />Improve the quality of connections, deliver not only information but also knowledge. <br />30<br />
