Maybe I can help you a little bit about the word ''Mechanisme'' in french

Basically, ''Mecanisme'' means the same as mecanism in english. Like : ''an assembly of moving parts performing a complete functional motion, often being part of a large machine; linkage.''
In French literature, poetry and in older French (like in Czerny's time), Mecanisme often refers to the mechanism of the body; it is compared to a machine.
''Etudes du Mecanisme'' would mean the exact same thing as ''Study of the mecanism''.
And ''ecole'' means school.
Can't help you much more than that, since I'm not sure what technique actually is hahahah
Have a nice day !
