Different kinds of experiences lead to different brain structures.
-Dr. Bruce D. Berry, Baylor College of Medicine
“Children raised with the computer
“think differently from the rest of us.
They develop hypertext minds. They leap around. It’s as though their
cognitive structures were parallel, not sequential.” . . . “Linear thought
processes that dominate educational systems now can actually retard
learning for brains developed through
game and Web-surfing processes
on the computer.”

Digital Natives
• Speedy access to information
• Parallel processing
• Graphics over text
• Random access (hypertext)
• Constantly
interconnected
• Games

Social Networks as New Web Portals
• Social networks: Web within webs
• Using Web 2.0, social networks provide a single point of access to various serrvices
• Facebook has over 52,000 different applications
• Yahoo!, Google and Facebook users spent 200 billion minutes (139 million days) on these
services in one month (October 2008)
• Google’s mission is “to organize the world’s content”, social
networks’ mission is to “organize the world’s people”
• The mission is not to create
virtual destinations but to “build constellations” by combining
“connectivity, communications,
and content”

. . .when CNN saw the image it moved quickly to
confirm with Dutch officials that a crash had happened. "Within minutes
we were reporting on the story. We then confirmed with the Twitter user that
the image was theirs and took it to air. "This proves that social networking sites
can be a real asset in covering breaking news and gathering eyewitness
accounts but the web should always be treated
with extreme caution,"
“You are what you tweet”!

What is Web 2.0?
“”. .second generation of web development and design that
facilitates communication, secure information sharing, . .
interoperability, and collaboration on the . . . Web. Web 2.0
concepts have led to the
development and evolution of web-based communities, hosted services, and applications such as social-networking sites, video- sharing sites, wikis, blogs, and folksonomies.”
