Today he talked about the difference between Hiragana, Katakana, and Kanji. Hiragana is sort of like a phonetic alphabet, and Katakana is also, but it is used to spell out foreign words and onomatopoeia, and a couple other uses. Kanji, is like Chinese characters- well, they actually are Chinese characters, but they don't necessarily mean the same thing they do in Chinese, and the all also have several meanings. I've almost memorized all the Hiragana, using the aforementioned smart.fm website, and I'll start Katakana once I have seen every one.
So far, I really like the textbook- very clear, personable and even funny, but I haven't yet seen any of his teaching methods, so more on that later.
