 A picture is worth a thousand words is a  proverb that refers to the idea that complex

stories can be told with just a single still image, or that an image may be more

influential than a substantial amount of text. It also aptly characterizes the goals of 

visualization where large amounts of data must be absorbed quickly.

Teaching and Learning with Images.For many teachers PowerPoint is used primarily as a tool for designing and

developing graphics. This section illustrates how PowerPoint’s potential for 

developing and delivering teaching resources is enhanced with the application of a

range of Web 2.0 technologies.

1. Image sources:

There are many WWW sources for graphics, photos and cartoons. The most popular 

technique for locating these sources is Google’s image search engine at

http://images.google.com/ . Using Google’s Advanced Search function allows you to

specify ‘file type’, ‘color’, ‘size’, and ‘faces’. Here are some teacher 

recommendations for locating images for teaching resources.

From the EduBlogs blog:

“Finding good images is always a quest so I am beginning to put together aresource that might be helpful for teachers. I am trying to keep the

explanation simple and the focus on sites that are free and quick and easy tonavigate.”

From the LifeHacker blog:“You can find all sorts of freely available images for use on your site or blog with this

compilation of public domain image sites from Wikipedia.”AND

“Check out 6 ways you can find legally-republishable content on the web.”

2. Online Image Editors.

PowerPoint can be used to create graphics and apply enhancements to photos e.g. add

text, callouts, borders, cropping, etc. The PowerPoint slide/s can then be saved as

.gif/.jpg images for use as a teaching resource either in a handout or online delivery

tool.

However, the saved image will need to be cropped to remove the part of the slide

surrounding the actual image. This can be done using desktop applications such as

PhotoShop and Paint or an online WWW editing service such as PICNIK or 

FAUXTO. These editors also enable images (graphics and photos) to be further 

enhanced using functions that include rotate, sharpen, resize, and special effects.

For example:

Image Resources Online Delivery.

There are a range of web host services that provide free storage for image files. Many

of these services provide image players that can be embedded in wikis, blogs and websites. After the images, presentations or documents have been uploaded the service

 provides a code in html that defines the size of a player and the file to be played. The

code can be copied and embedded in a wiki or blog.

For example:

Bubble Share

Scribd.

5. Wiki Books

A wikibook is a book that can be authored collaboratively and edited by anybody.

In the collaborative development of a wikibook the topics or chapters for the subject

are defined and allocated to members of the group/class for development.

A wiki or a space within a wiki is created for the wikibook and structured to enablechapters to be imbedded by the “book’s”authors. Content may be added directly to the

wikibook or embedded from a PowerPoint or Video hosted web service e.g.

Slideshare, Vimeo, YouTube, etc.

Digital Stories

Digital Storytelling refers to using new digital tools to help ordinary people to tell

their own real-life stories. These stories usually takes the form of a relatively short

story (less than 8 minutes) and can involve interactivity.

The philosophy of digital storytelling is one of using technology to enable those

without a technical background to produce works that tell a story using moving

images and sound. The product is a 2-5 minute film that combines a narrated piece of 

 personal writing, photographic images and a musical soundtrack.

As with wikibooks, high level learning can occur in designing and developing digital

stories as students analyse available content, synthesise selected material and

 progressively evaluate the development of the product. Preparation of a storyboard

 prototype emphasises the importance of planning in all aspects of life.
