Reflections Chapter 3 - Why is it important to learn about different technology tools when they are constantly changing?

The text states that although new technology is being release, most are backwards compatible. This means that they all work off the same basic platform. Newer technology will usually work with other technology over a five- to seven- year spread. So if a teacher knows how to use a desktop they would really beadle to use the newest laptop because they are the same basic functions. Also as technology advances we find new ways to use it in the classroom; we need to keep up to date so we move with the times.
