Low level dungeons often throw out 2-3 different debuffs. Using and saving your dispel for an actually dangerous debuff. On the flipside, using debuffs early enough so you can dispel more debuffs.

Also there are bosses that give a player a timed debuff (dispel at x stacks so the explosion is manageable but the debuff doesn't fly around the raid all the time). And at last, dispelling is a major part of playing healers in PvP, so it should be taught if people want to go there.
