Shoujo Kyouiko -

Could you clarify what context you encountered the term in? I’m happy to provide a more tailored response.

It seems you might be referring to (少女教育), which translates to Girls' Education . There isn't a widely known series or concept called "Shoujo Kyouiko" — the spelling likely has a small typo ("kyouiko" instead of "kyouiku"). shoujo kyouiko
