Do you know the genius of Google docs? It's helped me become a much more organized person, with regard to my teaching for the following reasons:
1.I no longer worry about USB sticks, or emailing myself documents, or any of that annoying stuff. I just use Google docs and then I can open anything, anywhere that has internet. This works amazingly well for any powerpoint stuff that I use in class.
2. I have a MAC, which in Korea sometimes just doesn't work out. Many Korean computers are not compatible with any Word or Text MAC file that I would try to open on them. However, by using Google docs this is not a problem.
3. I now keep a much better record of my lesson plans/syllabus/tests. In fact, I do them all on Google docs and plan on keeping them forever. And, it will be so easy to search for what I need. And, I can revise them easily from anywhere.
