Meet Abby, the digital native!

What is web 2.0, then?
The definitions abound! Web 2.0 = the web as platform Web 2.0 = the underlying
philosophy of relinquishing control Web 2.0 = glocalization (“making
global information available to local social contexts and giving people the flexibility to find, organize, share and create information in a locally meaningful fashion that is globally accessible”)
5
More of what is web 2.0
Web 2.0 = an attitude not a technology
Web 2.0 = when data, interface and metadata no longer need to go hand in hand
Web 2.0 = action-at-a-distance interactions and ad hoc integration
Web 2.0 = power and control via APIs
Web 2.0 = giving up control and setting the data free
6
It’s all of that, and more! Web 2.0 is social, it’s open (or at least
it should be), it’s letting go of control over your data, it’s mixing the global with the local. Web 2.0 is about new interfaces - new ways of searching and accessing Web content. And last but not least, Web 2.0 is a platform - and not just for developers to create web applications like Gmail and Flickr. The Web is a platform to build on for educators, media, politics, community, for virtually everyone in fact!

Web 2.0 and constructivism
What is the Connection Between Web 2.0 and Constructivist Theory?
Web 2.0 tools can . . . allow students/learners to demonstrate their understanding in a variety of ways. They can blog, edit, contribute, rank, tag, upload and enhance their web experiences through the use of Web 2.0 tools. Additionally through the use of social networking, learners can also be exposed to other learners’ perspectives on a given topic or subject.

Elements of Web 2.0
Wikis and blogs and all What is a blog?• ‘A weblog is kind of a continual tour,
with a human guide who you get to know. There are many guides to choose from, each develops an audience, and there’s also comraderie [camaraderie] and politics between the people who run weblogs, they point to each other, in all kinds of structures, graphs, loops, etc.’

Dave Winer is one of the pioneers of blogging.
This blog began in 1997. Davenet is from 1994,

What is a Blog?
•A log of websites visited? Or a personal journal? Or something else?“Defining this variable form is not easy in the highly opinionated blogosphere - nor is it simple in the increasing number of newsrooms that are in embracing blogging. . . . Capturing the blogging beast is no small matter, not when everybody from the lonely scribe in Paducah to me-too mass media in Manhattan is trying to get arms and minds around the virtual blob now encroaching online.”
•Just what is a blog, anyway?

Can we define blogs?
•“I don’t care,” “There is no need to define ‘blog.’
. . . A blog is merely a tool that lets you do anything from change the world to share your shopping list. People will use it however they wish. And it is way too soon in the invention of uses for this tool to limit it with a set definition.”
• Jeff Jarvis, the veteran print journalist and prominent blogger behind BuzzMachine Quoted by Conniff in Just what is a blog, anyway?
15
OK-so what makes a blog?
•Technically, what is a weblog? A weblog is a hierarchy of
text, images, media objects and data, arranged chronologically, that can be viewed in an HTML browser.

Another technical definition
• “. . . here’s a definition of what a blog is: A publication of
content and Web links, sorted in chronological order, with the most recent at the top. The content reflects personal or corporate interests, and is almost always written by an individual. . . .”

History of blogs
•Rebecca Blood: The original weblogs were link-driven sites.
Each was a mixture in unique proportions of links, commentary, and personal thoughts and essays.
These weblogs provide a valuable filtering function for their readers. The web has been, in effect, pre-surfed for them.• weblogs: a history and perspective 7 september
2000 rebecca's pocket • “Jesse’s ‘page of only weblogs’ lists the 23 known
to be in existence at the beginning of 1999.” “. . . last updated on 12 Oct 2000” with about 200 or 300.

1999 the year it all exploded•Early 1999: – Peter Merholz coins the term blog
after announcing he was going to pronounce web blogs as “wee-blog”. This was then shortened to blog.
•Early 1999: – Brigitte Eaton starts the first portal
devoted to blogs with about 50 listings.•July 1999: – Metafilter’s earliest archives.
•July 1999: – Pitas launches the first free build
your own blog web tool. •August 1999: – Pyra releases Blogger which becomes the
most popular web based blogging tool to date, and popularizes blogging with mainstream internet users.
For What It's Worth
I've decided to pronounce the word "weblog" as wee'- blog. Or "blog" for short.

Importance of 1999?
•Advent of easy-edit web interface• July 1999 . . . Pitas, the first free build-your-own-weblog tool launched
• In August, Pyra released Blogger, and Groksoup launched
• Late in 1999 software developer Dave Winer introduced Edit This Page [a forerunner of Blog This?], and Jeff A. Campbell launched Velocinews
• All of these services are free, and all of them are designed to enable individuals to publish their own weblogs quickly and easily.• Rebecca Blood, weblogs: a history and perspective

Why was Blogger so revolutionary?
•Rebecca Blood’s opinion: Blogger itself places no restrictions on
the form of content being posted. Its web interface, accessible from any browser, consists of an empty form box into which the blogger can type...anything: a passing thought, an extended essay, or a childhood recollection. With a click, Blogger will post the...whatever...on the writer's website, archive it in the proper place, and present the writer with another empty box, just waiting to be filled.

Can blogging be “safe”?
Safe blogs becoming a part of school The fear of encouraging social networking and
leaving the door open for unsavory individuals to see what students are doing online has caused most districts to avoid the tool, said David Warlick, a North Carolina public speaker and author who's working on the second edition of “Classroom Blogging: A Teacher's Guide to the Blogosphere.”
But new educational software, such as Virtual Office or Moodle, which the Muskego-Norway School District has implemented this year, protects students by letting them "publish" their writing within a secure server where teachers can monitor the comments.

What about wikis?
What is a wiki? A wiki is a website where every
page can be edited in a web browser, by whomever happens to be reading it. It's so terrifically easy for people to jump in and revise pages that wikis are becoming known as the tool of choice for large, multiple-participant projects.• What Is a Wiki (and How to Use One f
or Your Projects) by Tom Stafford, Matt Webb 07/07/2006

Does it have anything to do with Wikipedia?
Wikipedia is a wiki The name “Wikipedia” is a
portmanteau (a combination of portions of two words and their meanings) of the words wiki (a type of collaborative Web site) and encyclopedia.
Wikipedia is written collaboratively by volunteers from all around the world; anyone can edit it.• Wikipedia:About see also

What does it have to do with a hula dancer?
The word “wiki” is Hawai’ian Explanation by the inventor of wikis,
Ward Cunningham:• Wiki wiki is the first Hawai'ian term I learned
on my first visit to the islands. The airport counter agent directed me to take the wiki wiki bus between terminals. I said what? He explained that wiki wiki meant quick.
Did you intend the word to be pronounced as wee-kee (rhyming with leaky) or as wick-ey (rhyming with sticky)? • believe the former is the proper
pronunciation though I’ve been known to use the latter.

Ward Cunningham invented wiki in
1995.

There is an index to wikis online
WikiIndex.org WikiIndex is the wiki of wikis. It is
an effort to create a complete directory of wiki websites out there on the Internet, with a description of each wiki and various systems of categorisation. We want to help people find the kinds of wikis they are most interested in and to map out the Internet-wide wiki landscape. • http://www.aboutus.org/WikiIndex.org

Social networking
Social networking is the grouping of individuals into specific groups, like small rural communities or a neighborhood subdivision, if you will. Although social networking is possible in person, especially in schools or in the workplace, it is most popular online.
Social networking websites function like an online community of internet users.

What exactly is it?Definition:
We define social network sites as web-based services that allow individuals to (1) construct a public or semi-public profile within a bounded system, (2) articulate a list of other users with whom they share a connection, and (3) view and traverse their list of connections and those made by others within the system.• boyd, d. m., & Ellison, N.

A Sample Glog for
Web 2.0 sites
TeachersFirst Edge Entry: For moderately adventurous technology users (teachers) and most student users (with significant help in primary grades). Glogster EDU is a tool to create online multimedia "posters" that can incorporate all types of elements into a visual space: links, images, text, videos, music, and more. Your students will have multiple ways to express themselves and to learn from each other, making it easy for you to differentiate and engage each student. Here is an example glog created by the TeachersFirst Edge team.

Web 2.0 and safety issuesHelp Kids Socialize Safely Online
Help your kids understand what information should be private
Use privacy settings to restrict who can access and post on your child's website.
Explain that kids should post only information that you — and they — are comfortable with others seeing
Remind your kids that once they post information online, they can't take it back
Know how your kids are getting online Talk to your kids about bullying Talk to your kids about avoiding sex talk online Tell your kids to trust their gut if they have
suspicions Read sites’ privacy policies
45
Find a good balance, though!
You can be too restrictive! Content filters and firewalls are great for keeping
kids away from pornography, as required by the Children’s Internet Protection Act (download the PDF), or preventing them from updating their Facebook status during class. But the same filters can stop teachers from accessing cutting-edge widgets and digital materials that have enormous potential for expanding learning.
New Hampshire kindergarten teacher Maria Knee, a pioneer in using Web 2.0 tools with young learners, points out that keeping powerful tools out of students’ reach during the school day doesn't prepare them for life. "Our kids are going to be using these tools and sites anyway," she argues.

Trying to prepare students for their future and teach them about Internet safety without Web 2.0 in schools is like trying to teach a child to swim without a swimming pool!
