Wikis

I corrected a wiki page on Tennis. The previous writer had incorrectly written that a continental grip would cause the player to produce a slice or back spin shot. This is wrong. After playing competitive tennis for 9 years, I have learned that a continental grip will cause the ball to be hit flat (with little or no spin). Unless you motion your arm in a 'spoon' like path, straight and dip a bit while hitting the ball, then you will most likely get what is known as a 'moon' shot, which goes very high up and most times out of the court, costing you the point.

What I found most interesting about the Tennis section, is how all of the information that has gone around in the tennis world, is on that page. From tournament wins to strengths and weaknesses of certain court surfaces (clay, grass, concrete) and how to watch for them, or use them to your advantage. For example, play is very fast on concrete, this should make the player more aware to get ready faster, and be more prepared to analyze their opponent's shots. Whereas clay is very slow, and will allow you to slide when diving or reaching out for the ball, giving you more time, and reach.

The applications within schools that might work well with wikis are to have a database, made by the students and teachers alike, filled with all the information possible of the level of that course. For example, a physics wiki would include all types of definitions and diagrams of experiments, successes, and failures of past physicists. A wiki is very useful, however it is somewhat dangerous for readers because the material may be from an unreliable source, or from a previous editor who had no idea of what they were writing about, leading us to the wrong information. That is why it is important to have several sources.
