Doug Johnson's Seven Stupid Mistakes and Seven Brilliant Things Teachers do with Technology

After reading the list of the Seven Stupid Mistakes Teachers Make with Technology, these two seemed the most important to me:
1. Not backing up data
The standard OS is built up around thousands of code that at any moment could glitch. Not having grades, papers, research, or even websites backed up could set a person back years.
5. Believing that one's teaching style need not change to take full advantage of technology
This is a new world when compared to the times they started teacher. Books, libraries, and teachings are no longer the necessary when it comes to proper study. Researching a paragraph online rather than hunting down a book, then flipping through the pages takes mere minutes when compared to the latter.

After reading of the list of Seven Brilliant things Teachers do with Technology, these are the two I think are most important.
4. Put kids in touch with the world.
Lets face it, there is a real world out there that has more than a small town can offer. A child needs to realize that they are just part of a bigger picture, the scope of the world around them is mind boggling, but if prepared for the vastness that is society at a younger age the child can adapt. Probably even come to realize that the world needs fixing and it his their job to do so
3. Make conferencing real-time.
People need to be in the know, often times scheduled appointments just can't be made. If the teacher is more willing to keep in touch with students outside of class then a whole new level of respect appears. The child will slowly realize that the teacher really does care about their future and could start taking things more seriously.
