The only web-based tool I would think I would use would be some kind of blog or wiki like the ones we were using: Wikispaces and Blogger. Wikispaces or any of the other wikis could be useful for sharing information with students. Most college students (my intended audience) would be able to surf them and learn from them pretty easily. I can picture myself putting up useful links and reviews of my lectures, etc. for their browsing pleasure. I think it would be a good review resource if nothing else and would help students search other resources if they were interested in a certain topic.
Blogs would be useful for student-teacher communication, or just to amuse them by telling them what I am up to. Again, I could share resources that I have found recently. In the more advanced sections, I would be able to share certain parts of my research with my students. I could post excerpts from reading for my students to be required to read and discuss. It would be a very helpful tool to be able to share information on the fly and send out an email saying there is updated information for people to check. It would be fast and get the work out quick. I can't see that being a poor use of resources.
For a technology-related skill, I would say more familiarity with certain programs would be nice to have. Also, just practical use in the classroom and experience with actual technology would be quite useful. I think creating more PowerPoint presentations might help me to become more familiar with the program and help with design and lectures for the future. Excel, I can't really see myself using except for maybe grading (which the school usually provides a different program for). I don't know if this would be referred to as a technology-related skill, but perhaps being able to stand reading ebooks (as I prefer having a physical copy and can't stand the alternative) would be beneficial in the future (especially as I plan on teaching some form of literature or writing).
I would say the primary means towards furthering my technological education would simply be experience. I think with more experience with the programs that I will be utilizing, I will be able to create better and more useful presentations and organize information better for my students. I am hoping I can shock and awe, as I have no plans to be a mediocre teacher. We will see though. But again, as I get into teaching, I am sure as my experience builds, I will become more comfortable in my setting and with organizing lectures and teaching.
