She's working on her term paper, you know.
Literal
She [topic-は] term-end report [object-を] is-creating [you-know-よ].
The sentence-final よ does the work English handles with intonation and tags like 'you know' or '...for your information.' It marks the speaker as informing the listener of something they may not yet know — assertive, sometimes mildly emphatic. Compare: 作成しています (neutral 'is producing') and 作成していますよ ('is producing — letting you know'). 作成する is the formal verb for creating documents or content, more weighty than 書く ('write') or 作る ('make'). The ~ています polite progressive lifts the register; the ending よ makes it conversational.
