What’s different about the new version of Tadashii Kanji Kakitori-kun? First, instead of stopping at the 1,006 Kyouiku kanji, it includes the full 1,945 Jouyou set.
Next, the core writing module is considerably better. One frustration with the first edition was that it only taught shape and stroke order; if you didn’t remember what the character meant or sounded like, you had to look it up somewhere else. The new version doesn’t have the search capabilities of a real kanji dictionary, but does have readings, meanings, and vocabulary words. It also adds detailed critiques of your characters, graphically showing your errors.
They’ve also completely redone the drill and test modules, for the needs of a more sophisticated audience. This is the only place where it’s not as useful for a foreign student, because the previous edition broke up the jukugo drills by grade, and this one lumps all of the grade-school kanji into one set. The Kanji Kentei prep section is now more of a timed test than a drill, although it’s still divided by grade.
I’m currently ripping through the kyouiku kanji in the new one, so I can start on the junior-high section, but I’m going to continue working through the drills on the old one.
