I'm afraid, as I'm not an English teacher, I can't help you in your specific problem. I'm currently trying to learn Thai, which is (supposedly!) a phonetic language (which should make it easier) but it has the added difficulty of being a "tonal" (high, medium, low, rising and falling tones) language.
I have not come across the strategies available in "FLL/SLA(?)".
Could you please advise what the acronyms stand for or, better still, provide a link to appropriate websites.
