For my son's Hifdh class he uses the "wooden tablet method" (LauHa). That is, he has to write the chapter he is memorising on a wooden tablet, with a home made ink, they call Smaagh. DH is convinced this method is superior for memorising the Qur'an, lol. He used to get his chapters dictated to him though.
We used the dictation method too, when I was young. But we used regular pen and paper.
DS had to get a wooden tablet, a feather pen 'reeshah' or calligraphy pen and make 'Smaagh', before he finished reciting his first Hizb (most of which was just repetition). This is brown 'Smaagh', as it is when bought.
It is grinded and mixed with boiling water, and then left to cool.
After writing what he's managed to get down in one day (it takes a lot of patience to write even one stroke with those pens), he then takes the tablet with him to the mosque, 'memorises' it (he already knows most of it, he just learns to recite it in Warsh instead of Hafs), recites it to the sheikh, and then he has to reread it 100 times.
The writing goes very slowly, and he's now tried four different pens, plus faking it with a pencil and a calligraphy pen for regular ink! The best pen is the one made of a kind of bamboo stick, called qsab. It retains the ink for longer, making the dipping in the ink farther apart.
His hand writing and reading skills are getting better, inshaa Allah, although he forgets his glasses more often than not, and he still makes mistakes of the kind I've mentioned before (in the posts on dyslexia). The biggest problem I'm having is getting him to spend time with me, though, so I can't really tell where he's having a hard time or if there truly is a problem, nor can I help him where he needs it.
I thought it would be to his advantage to learn Warsh too, but I think sometimes that they are held back, not advancing as fast as they could. For example, when they turn in the tablets, they're not allowed to write any more until two 'mosque'-days later (he goes four to five days a week), and on the days he's off he rarely does any memorising or writing. With the pace he's writing in, he doesn't learn half as quickly as when he used to listen to cassettes only.
The other issues I have with this class, is the lack of instruction in the tajweed rules. DS has only sat down with the sheikh once in four months, to go through the differences between Hafs and Warsh. He would have benefited with some repetition!
The unbelievably fast pace they recite in! How on earth can the shuyukh hear if (and when!) the kids make a fault?!
And they do no tafseer, whatsoever. It's purely, and only, taHfeedh, unfortunately.
