The basic problem, according to officials, is that Wikipedia’s unverified accuracy and ease of use are making it too tempting for students to use as a primary source.
Yeah, it’s a great idea to prevent students from getting information when doing research for school.
Teach students about credibility, then give them access to whatever they want. Reduce their grades if they don’t cite credible information. Remember, most significant Wikipedia articles now include that giant citation section at the bottom — so even if you don’t think Wikipedia itself is credible, you can at least use it as a starting point to find other sources.
Nothing has changed since I was in high school (this was my school) in 1996. School administrators are still remarkably good at ensuring that their computers are completely useless for any educational purpose.
