I did a lot of rote learning when I was a student and when working in Japan and had half hour or more trips on buses and trains, especially when it was standing-room only. (I learnt 2000 Kanji on a train one year and wore a hole in the leg of my jeans.) I also used to learn one word while I brushed my teeth, another while I ate breakfast, etc., etc.
It is interesting how your mind and body can retain unrelated and redundant information from the environment. Now, when I see or hear a word I learnt back then, I sometimes have flashbacks to a place or an event that occurred while I was learning that word. The mind seems to tie all of the information together in intricate patterns some of which are useful, some not.
Using colors? Could be good...but I wonder if you might not also end up learning words from cards in your favorite color better than those in a color you don't like as much!
Jokes aside, here are some tips for making and learning from cards (from my experience only, others may have had different experiences):
1. Half of the learning from cards occurs in the writing that you do when you make them and the fact that you see the word as you write (and if you make a mistake it has a tendency also to stick tight if you learn by rote.) So, it is better to make your cards by hand writing them yourself rather than printing them from a printer.
My card making always outpaced the rote learning and I still have boxes and boxes of unused cards somewhere (all on recycled bits of paper, of course ;-) ).
2. When you learn a word try to picture the concept, if possible. Think of "coldness" when you learn
fuar or picture a boat as you learn
bád, etc.
3. When I started learning, I just learned the dictionary form of each noun with its gender but as I got more advanced I eventually got to writing out a set of declensions with the article for each noun to help with gender and plural:
bád (m1)
an bád
an bháid
na báid
na mbád
bean (f)
an bhean
na mná
na mná
na mban
That is a lot of work, but like I said, the process of writing up the cards was more important in the end than actually using them for rote.
For regular verbs, aim for imperative (imperative plural), verbal noun, past tense, present tense and past participle (Other tenses can easily be derived from these.):
bris (brisigí)
ag briseadh
bhris sé
briseann sí
briste
oscail (osclaígí)
ag oscailt
d'oscail sé
osclaíonn sí
oscailte
Adjectives, nominative and comparative:
bán
níos báine
suimiúil
níos suimiúla
Of course, if you could do all that, you wouldn't need the cards in the first place. Start off simple and work towards the above.
As I have said, it is the process of looking up dictionaries, etc., to find the different elements in the declensions and conjugations that really helps you learn, not the cards themselves.
