Users of social networking wunderapp Facebook know that not only is the site a great way to waste whole days throwing sheep and zombie-biting people but you can also keep tabs on all of your friends. I spend more than enough time online and ignore anything on Facebook except messages (so if you have been wondering why your ninja invitation lies unanswered - now you know!) but I am only human, and when I noticed an app called Kanji Box my curiosity was piqued. Kanji Box is a simple quiz application which operates within Facebook. It allows you to choose an ability level (grasshopper through to JLPT Level 1) and then test yourself on kana, kanji and vocabulary. Once you have trained up via the drill function you can sit a quiz and then get feedback in the form of stats: having a score is a great motivation because it gives you a clear target to beat next time you sit the quiz. The stats page also shows your progress in terms of both JLPT level and 常用漢字 - General Use kanji (plus the 人名用漢字 - kanji used in personal names). I gave the quiz function a try. Fast, straightforward and fun - if you are going to blow off some time online at least with Kanji Box you are learning something (not that zombie-fighting isn't a useful skill......). The best part is the social networking aspect - you can invite friends and compare scores. Nothing quite like the motivational factor of "OMGWTF! - Tom scored 1076 points on JLPT Level 1! My score is pathetic - better start drilling." (cue Rocky theme song)
Since we are all wont to visit Facebook at some time or other I recommend Kanji Box as a way to harness the power of constructive procrastination. The only downside - at some point your concentration will waver and you will start seaching for that girl who used to sit next to you in kindergarten. And it's a minor bugbear, but I like kanji for either the singular or plural - "kanjis" sounds like a type of fruit or a venereal disease.
(I'm off to see if I can match Tom's score.)
