I believe that using Web 2.0 for K-12 education is very benefital for the students. It allows for them to have very hands on experiences with technology. There are very goodprograms and softwares that are associated with it that can help students with several aspects. Pretty much anything can be taught using Web 2.0.

I think using wikipidea is a very unrealiable source. Like they say "anyone can publish on wikipidea" a lot of the information in wikipidea is very true, reliable, and many sources used on wikipidea are very excellet. But that is not to say that most information is false. As a form of research, it should not be accepeted.

I think learning all the different effects on slide show will be effective. As a teacher you have to always constaly engage your students and learning these effects would do so. For example, how to make a clip art object move acrosss the screen is a good thing to learn because like that you can do little things to keep the students interested.
