Writing has always been a two-dimensional process, allowing us to write across and down the page. New technology adds the third dimension, allowing students to create hyperlinks to expand on any particular word or phrase. Suppose a student is writing a report on energy and mentions nuclear fission. She could then create a section at the end of the report and write a detailed definition of nuclear fission and include a graphic. The phrase "nuclear fission" would then be linked to this definition so that an on-line reader could easily link to the definition and then return to the report. Suppose a student is writing a story about bears and discovers that the kodiak bear is found in Alaska. The word "Alaska" could become a link to a map and description of the environment. We call this three-dimensional writing. This is the writing of the World Wide Web -- a skill students need to learn.
