Actually, I'm having the same question as supermancampus; while Heisig 1 went relatively well for me (around 90% retention) my retention dropped like a well-oiled brick when starting vocab. So I, too, am wondering how to effectively learn vocabulary.
The sentence-based method definitely seems interesting. I think it may make learning in the sense of not failing the cards easier, but would seem to have as risk that the word is harder to recognize outside the sentence, and may cost more time due to all the 'extraneous' context to read, especially for a beginner like me who can not read Japanese very quickly yet.
And forgetting words again and again - in my experience (and as far as I understand memory research) retention increases with the vividness/importance of the item, and decreases with the complexity of it. For example, I find words like "雨" (あめ) easy to learn, both since it has few letters and I get soaked often since I live in a very rainy country. However, I have significantly more trouble with 引き続き, which is quite a long word and a bit more abstract. I think this means that for a beginner like myself, focusing on short, simple words at first may be advisable; it may be easier to learn words like 面白い if you have first learned 白い, which is actually easy to remember if you know that Japanese sometimes avoid the number four because it is associated with death (し) and white is the colour of mourning. But I digress. Anyway, I think Overture's point in liberally suspending hard cards makes lots of sense.
The four different methods I'm testing so far for retention are as follows:
1) learn by 'usage'. I try to use the new word while talking to myself a few times as 'substitute' in an English sentence. For example 'Asatte I will take a walk in the forest' 'Asatte evening, I'll return home'. I do this three times, sometimes on my bike, and occasionally a day or a few days later again. So far, retention seems to be reasonably well with this method.
2) learn from texts; though in my case I use the lyrics of songs I find on youtube and put the individual words in Anki; the song is just to sing in my free time and make a sort of meaningful rehearsal. Example: I'm now learning the vocab from
, singing to myself in empty moments like in the supermarket or while traveling "見せて 上げよう 輝く世界..." Disadvantage: it can take some time to get to the right video and you often need to convert verbs back to their 'native form'. Overall, though, an enjoyable form of learning, and words seem to stick relatively well.
3) 'raw kanji visualization'. For example, if I see 格好いい, I use Heisig and miscellanous associations based on the raw form to turn the 'raw visuals' into something memorable. For example, 格 ('status' in Heisig), I recognize as one of my status-conscious family members, which in Dutch is fortunately called 'kak'. Based on that, remembering the 'ko' is quite doable (right side of 好 is child, which has 'ko' as one of the kun-yomi). With elementary hirigana reading I now have kakkoshii (かっこいい) Remembering the meaning, 'cool'/attractive, is then a relatively small burden. I'm also experimenting with this method, but much depends on how successful my associations are, method [1] seems more robust at the moment.
4) pronounciation->meaning->kanji. It may also be possible to start with the hirigana and learn the meaning as a first step; when that has been done, you could probably easily learn to recognize the correct kanji if you know Heisig. So this would be more like breaking the learning into two steps; first pronounciation/meaning, after succes on that, work on to kanji->pronounciation->meaning.
Anyway, these four strategies, the 'words from sentences' method, and the 'raw SRS labor' make six methods; starting with short/easy words is a kind of additional strategy. Does anyone have methods to add that they have tried and worked well and less well, and how is the learning time compared to retention? I still have a few thousand words to go, so I'd love to test different strategies to see which work best for me.
