A teacher is someone charged with the educational instruction of others, usually within a specified field. Teachers may include private tutors, school teachers, college professors, military school instructors, as well as various fields of specialty, such as relgion or martial arts.
Teachers crop up quite often in the horror genre, particularly in media catering towards a teenage demographic. The Scream film series addresses some members of the Woodsboro High School faculty. In television, high school and college teachers pop up all the time, such as in shows like Buffy the Vampire Slayer, Teen Wolf and Vampire High.
