Using Storytelling as the Pedagogical Model <strong>for</strong> <strong>Web</strong>-Based <strong>Learning</strong><br />

DEVELOPING STORY AUTHORING<br />

TOOLS IN WEB 2.0<br />

The past few years have seen large volumes <strong>of</strong><br />

user-generated content on the <strong>Web</strong> giving an ideal<br />

plat<strong>for</strong>m <strong>for</strong> CoPs to share their experiences. Rich<br />

Internet Applications (RIAs) allow users to post<br />

and share multimedia in<strong>for</strong>mation over the <strong>Web</strong><br />

<strong>for</strong> free. In 2007 the Time magazine proclaimed<br />

“You” (the general computing public) as the “Person<br />

<strong>of</strong> the Year” (Glass, 2007). The reasons given<br />

<strong>for</strong> this choice included <strong>Web</strong>-<strong>based</strong> collaboration<br />

opportunities, because:<br />

It’s “about community and collaboration.”<br />

It’s “about the many wresting power from the<br />

few.”<br />

It’s “the beast with a billion eyes”!<br />

However, Glass (2007) argues against this<br />

choice due to the misuse <strong>of</strong> the <strong>Web</strong> <strong>for</strong> frivolous<br />

and salacious activities. Despite rampant misuse <strong>of</strong><br />

the <strong>Web</strong>, the fact remains that <strong>Web</strong> 2.0 tools such<br />

as Blogs, RSS and Wikis have changed the way<br />

we communicate and keep ourselves in<strong>for</strong>med.<br />

Current <strong>Web</strong> 2.0 Development<br />

Environments<br />

The <strong>Web</strong> 2.0 environments that provide tools<br />

<strong>for</strong> building Rich Internet Applications include<br />

AJAX, Flash and XULRunner (Farrell & Nezlek,<br />

2007).<br />

Asynchronous JavaScript<br />

and XML (AJAX)<br />

Asynchronous JavaScript and XML (AJAX)<br />

provides a highly responsive user experience due<br />

to the fact that it constantly loads small chunks<br />

<strong>of</strong> data in the background (Paulson, 2005). This<br />

aspect <strong>of</strong> AJAX makes it more responsive than the<br />

languages such as Hyper Text Markup Language<br />

(HTML) and Dynamic HTML (DHTML).<br />

In an AJAX <strong>based</strong> application the client can<br />

download in<strong>for</strong>mation –such as graphics and data–<br />

just once, and then these are updated incrementaly<br />

in real-time. This reduces the system response<br />

time appreciably (Backbase, 2008).<br />

Advantages <strong>of</strong> AJAX<br />

The asynchronous nature and other features <strong>of</strong><br />

AJAX have made it a popular choice <strong>for</strong> building<br />

Rich Internet Applications. The main advantages<br />

<strong>of</strong> AJAX framework include the following:<br />

1. Applications are more responsive as they<br />

don’t experience full-page reloading<br />

delays.<br />

2. It is <strong>based</strong> on open standards and widely used<br />

languages, namely JavaScript and XML;<br />

there<strong>for</strong>e it does not need plug-ins to run<br />

applications.<br />

3. Applications provide users with rich functionality<br />

and operate with all <strong>Web</strong>-browsers<br />

and plat<strong>for</strong>ms.<br />

4. It is being used widely to build <strong>Web</strong> 2.0<br />

applications.<br />

Challenges with AJAX<br />

However, AJAX has got some drawbacks as well,<br />

these include:<br />

1. It is a new technology, making the application<br />

development more expensive.<br />
