Do you remember this computer game from school?

ok ill try to give all the information i can. It was some kind of detective game (its not carmen sandiego but same era) that was on the computers at school when i was really young in the 90's. you were a guy who would walk around a school and try to solve who was doing mischief. you would sometimes see the guy in the act walking around. i think it was a math game but i am not sure. i just remember the guy wearing gles or something and i think u had all these gadgets too. it was pretty cartoony.
