This is probably one of the most debated subjects in all of technology. Is it reliable or is it not? Anyone can post anything (generally speaking) and many may see it and take it as the truth. There are ways for that information to be tracked and monitored, but it still gravely affects the site's credibility as a source of reliable information. I don't want to destroy Wikipedia entirely. I think it is a good starting point. I do, however, think that one should be VERY careful using the site and not trust it alone. Search out other information. Expand beyond Wikipedia and get more information from places that might hold just a little more credibility than Wikipedia.
Mr. McClung, a Missouri teacher, posted a blog about his first year of teaching. The insights he shared were really profound, but simple at the same time. The main thing that stuck out to me was about listening to your students and keeping your lessons student centered. So often, we teachers can get caught up in the test scores, student achievement, and so on that we forget that school is all about the students anyways. We forget that they are the entire reason we are in the position we are! So instead of trying to impress our superiors, let's listen to our students. Let's involve them in the learning process. They will be much more willing to learn and participate if they have a say-so in the way things go, with the teacher providing management and authority. And I believe that if we do that, the achievement and high scores will come!
