OKFN and OKF are the same thing: "Open Knowledge Foundation (OKF) is a global, non-profit network that promotes and shares information at no charge, including both content and data [--] founded by Rufus Pollock on 20 May 2004 [--] Between May 2016 and May 2019 the organisation was named Open Knowledge International"

You had started your AI project before 2004?

Yes, I think it will be somewhat random how many cases each child needs to be taught before they generalize. One thing I forgot to mention is that for polysyllabic words, they use a learning aid here: in the beginning, the syllable boundaries are marked with dashes in all text and in the second year, only in longer words. I don't know if it works in Spanish too, something like this: "A-yer ce-na-mos cons-ter-na-dos." Again, I think it's unnecessary for some children but helps others to keep learning while gaining more experience with the syllables.

In English, you never know: "a unit"

No, comprehension is again orthogonal to reading as it is needed in spoken language too. Remember: everybody's (unless you have a severe speech or hearing impairment as a baby) first language is a spoken language, and to extend it to a written language you will have to learn (be taught) an artificial orthography to map to and from. You can know a lot of vocabulary before learning to read (if you ever do). In a language with a phonemic writing system, your sets of spoken and written vocabulary are the same, whereas in English they only overlap. In both cases, knowing a word is orthogonal to knowing its meaning(s).

I think that only applies if learning to read in English. In a more phonemic writing system, if you can read, you can read any unfamiliar word too. This way, even a young child can read anything to quickly acquire more vocabulary unrelated to what their parents ever acquired.

"We used to think dyslexia was related to IQ but it's largely orthogonal." More specifically, dyslexia is not a generic learning disability, it's a highly specific one (and mostly preventable).

I think you misunderstand. In a largely phonetic language, almost everyone learns to read in one school semester, after which it's a fully solved problem - no spelling bees or anything. Peculiarly, you don't need spelling bees either when learning English later. ("Contronyms" and "words" are orthogonal to reading as they apply to spoken language too (and it's very much automatic).)

You should think "the step from single sounds to syllables", and the way to do that is to begin with the easy syllables like "tu", "mi", "el" (not unlike the multiplication or addition tables) before moving to longer ones. [And note that M alone is not "em", it has to be "m" when learning to read - a common pedagogical mistake! M + I makes "mi" not "emi", so M must be "m".] At least that's how children are taught in Finnish schools since sometime before the 1980s, and since then almost everyone learns to read during the first school semester. Also, one simple and efficient protection against dyslexia is to play the Graphogame (or similar) to get a lot of repetition with the sound-letter correspondences while learning to read (for various reasons, some brains take longer to build the necessary connections and you want to avoid the negative affects of learning slower than your peers if you can).
