Musicalrebel4 - By chance, is there a language based confusion here? All my acquaintances + teacher have Russian training, and all of them have movable do, not fixed do. I understand movable do to be the diatonic scale where in the major scale "do" is always the tonic. In G major, "do" falls on G, in C major "do" falls on C, in F major "do" falls on F, etc. By contrast, for "fixed do", as in France for example, in G major the tonic is called "sol", in F major the tonic is called "fa", because the solfeggio syllables take the place of the note names.
So in the way you were educated, was it the first, where "do" is always the tonic, or the second?
I grew up knowing only movable do solfege and not knowing note names. I have had to learn that more recently. Therefore I related to music relatively, always with the diatonic scale and familiar patterns behind me, like a ladder you could move up and down the keyboard and staff. Some things in note reading that others find hard are easy for me. However, I could easily transpose accidentally since I was not aware of pitches.
Joining note names and pitches to that is not only a matter of getting new names, but a totally different concept. In pitch association, which is the only Western way, an A is always an A regardless of what is happening around it, whether it is the third note of F major, part of a triad, or the first note in A major. Joining the world of pitch and note names with the world of relative pitch and orientation within scales makes music 3-dimensional.
In your system, when you have the children transposing, for example, are you gently leading them into a solfege kind of mentality so that they will have both of these worlds?
