It’s not just a tool
The power of Internet is underrated
Most people may still think Internet as a tool, just like radio or TV, that's true indeed 10 years ago.
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.
Then what's that has anything to do with knowledge?
4
The Internet and Writing
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.
The writing is toy for children, the speech is wisdom of adults.
5
The Internet and Writing
Time changes, and the wise can be wrong.
The knowledge for the first time can break through the limit of Time, and become permanent treasures of human beings.
That's how we stand on the shoulders of giants.
6
The Internet and Writing
Would it be possible that the mighty Internet help us break through the spatial
limit?
If you prefer it's YES, then let's move on.
7
Knowledge and Learning
What is knowledge?
Defined by the Oxford English Dictionary
Expertise and skillsFacts and informationAwareness or familiarity
BUT
We often forget the information as knowledge.
The information flows on Internet is the same as the knowledge bear in our mind.
Can we learn from Internet?

How to dodge a snakebite
9
The incoming contents
First, introduction of the connectivism as a learning theory.
Then, how Internet make it possible to learn in this way.
At last, we will try to dodge the snakebite.
10
Connectivism
Connection matters
From Wikipedia
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.
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.
11
Different program models
The traditional program model
The If-then model
if …then … ;
if …then … ;
if …then … ;
The possible problem and solution is coded by programmer.
The program is preset.
The knowledge is beard in mind of programmer, who write the program to make it explicit.
Like a guide book
12
Different program models
The connectionism program model
The network model
ProblemTraining
input
Answer Expected output
Solutions
The programmer build up network without any code.(a blank network)
Train the network with some input and expected output.* *(Learning)
Solve new problems in some degree
The knowledge is beard in the network and implicit
Like a student
*The training process will change the connection between nodes. e.g. enhance the right path.
13
Different learning approach
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.
14
Different learning approach
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.
15
The society as a network
What if we see the entire society as a network and every individual as a node
Problem Answer
16
It’s happening in everyday life
You won’t be the first one who meet such kind of problem, there’re someone who know how to deal with it. But,
Can you find them?
17
Internet for the rescue
Thanks to Internet, now the people we meet in one day can be more than that of Socrates’ whole life.
On what level has the world changed?Especially after the buzz word Web2.0 comes out.
18
How Internet shape the world
Be visible online
Web2.0 technologies make the Internet user friendly, so the content is user generated, which means more people are visible online.
19
How Internet shape the world
Be short and shorter
The content is short fragment rather than a chunk of systematic knowledge.
A Page A Blog A Tweet
20
How Internet shape the world
Be fast and faster
Therefore information spreads fast in this network.
One hour after the news of Jackson's death hits the internet, the first mainstream news source publishes a confirmation article.
21
How Internet shape the world
Information reorganization
What’s google’s content?
More than 80% content of this page is taken from other website.
Google just collects information and tell you where it is.
22
What would the learning be like then?
23
Still remember the case?
How to dodge a snakebite
24
In Web1.0 or before
Sorry, good luck next time, find a website about jungle exploring before you are in danger.
25
In Web2.0
This is what you get NOW, You may find a Blog about how to dodge it, or a Video clip of a real example.
But still sorry, before you click and see what’s that, you have already been bitten.
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.
26
In Web3.0
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.
Congratulations, now you dodged a snake bite successfully. Why not write down your experience and share with your friends?
27
It may take decades for
the Web3.0 to come, but
there’re something we
can do now to improve
the environment for
learning.
28
What to do
Tips for a better learning environment
Encourage more people to contribute to Internet and share knowledge.
More Resource
29
What to do
Tips for a better learning environment
Change the form of knowledge on Internet. Tear it into fragments and reorganize them according to problem.
More Problem-based
30
What to do
Tips for a better learning environment
Improve the quality of connections, deliver not only information but also knowledge.
More Professional Social-Network
