Web 1.0 to 2.0

Technology has played a role in teaching and learning for many years. For example, you might start by reading the book Mosquito Bite by Alexandra Siy and Dennis Kunkel. Students might then use a digital camera and software such as PowerPoint or Word to write their own story. In the last decade, the web has played an increasing role in technology-rich learning. Students might access online images of microscopic worlds and combine them with their own photographs. Some examples include:

Mosquito BiteThe introduction of Web 2.0 technology allows students to reach beyond the classroom. For example, they might take their own microscopic photographs and submit them to the Small World Photography contest. Search for bugs and get help with identifying bugs at BugGuide. Or, create a blog like Micro Images Blog that allows students to comment on the work of others. Smithsonian Encyclopedia of Life is a collaborative project by the US National Museum of Natural History to document the earth's diversity by scientists and citizens of Earth described by E.O. Wilson in The Creation. A related project is Consortium for the Barcode of Life. Check out the Barcode Blog.

Web 2.0 Lingo

Folksonomy - The use of tagging to catalog and classify web data in an online community. Unlike taxonomies like Sears Subject Headings that use a set list of terms, folksonomies allow individuals to invent their own key terms. Example: A teacher might label a novel "skinny" because she knows that kids seeking a short book might be attracted to this novel.

Mashup.The mixing or two or more web functions to create a more powerful application. Example: When you mix a map website with a photo website you get to see images from specific locations.
