Higher education institutions don't use it for their paranoid reasons of information being wrong, and I respect that. However, the reality is that most of the information on Wikipedia is accurate.
True, plus the internet in general, and wikipedia and google in particular, are making some skills of educators obsolete. In the coming years, some duties of educational institutions and libraries will begin to disappear. The world of information and experiences is at your fingertips, and old time educators have a hard time with it. But here are their legitimate concerns:
1. Using wikipedia as a source is impossible to verify because it changes.
2. Technically, any student could slap something on wikipedia, and suddenly it would be considered a "fact".
3. Wikipedia and other internet resources are like cliff notes times ten. No longer do you have to read Oliver Twist, just zip through a few condensed versions on the net, and you could pass most quizzes and tests. This is frightening to most teachers.
4. Although the vast majority of information on Wikipedia is accurate, a tiny percentage is indeed wrong, so educators throw out the entire baby of accurate information with the small amount of inaccurate bathwater. It's handy for them to do this, plus it's consistent with their worries as expressed above. Also, imagine reading a few dozen research papers which, amazingly, all contain the exact same piece of inaccurate information.
5. Wikipedia entries are often not well prioritized. Look up something near and dear to you on wikipedia, and you'll often find trivial details being given priority, with bigger issues being slighted or not mentioned at all. Again, imagine reading a few dozen research papers on Roy Disney that fail to mention that he once had tuberculosis, or mention ad nauseum that his tuberculosis colored his entire life. Neither version would appear to be accurate. A fully edited encyclopedia will have a better chance of having proper prioritizing.
6. Wikipedia, and classic encyclopedias, lack depth. Educators may be afraid that only shallow understanding will result from a society that constantly clicks on wikipedia for all their answers. Use wikipedia to look up Roy Disney sr., and you'll barely scratch the surface of this amazing man conpared to what you'll learn from a full biography. Good educators want you to find far more depth than this.
With all that being said, I love wikipedia, and I jump on it at least a hundred times a month. So it goes.
Now, just google TTA narration, and I guarantee you that no respectable source will opine that the new narration has any value whatsoever. So there.
