Is It Any Good?
ZulaWorld successfully blends teaching with virtual adventures to help kids learn basic math, science, and astronomy principles. It's a big site but has an excellent map and voice-enabled navigation bar. Kids can spend hours exploring ZulaWorld without paying a dime; even the site's best game, an addictive Space Invaders knockoff called Meteor Blast, is free. But to complete all the missions, equip spaceships, and fully interact with other avatars requires a monthly subscription fee. ZulaWorld is worth the price of admission despite needing some tweaks. It needs a better FAQ and more hover popups so new users don't have to guess before clicking. The interactive dictionary should be accessible at all times so kids can look up words whenever they want, not just when they've completed a task. ZulaWorld was out of beta but some parts were still under construction when I visited in June 2009. Overall, though, it gets a big thumbs up for great educational content wrapped in a fun virtual world.
