Classroom

A classroom is a place where students are taught by a teacher.

Prior to her assignment aboard in 2151, Hoshi Sato worked as a linguistic teacher in Brazil on Earth. She taught her class in an exterior classroom. 

Aboard the starship, there were several small schools of varying sizes located throughout the ship, ranging from actual classrooms  to specialized workshops. 

Keiko O'Brien opened a school on Deep Space 9 in 2369. To aid her in this purpose, her husband converted a room on the Promenade into a classroom. 

DS9's classroom was damaged by a bomb later that year, after Vedek Winn Adami started protesting against the secular subjects taught by Keiko.
