One of the most important things a substitute can do to manage the classroom is to follow the instructions left by the regular teacher. Some substitutes feel at liberty to ad lib and do what they think is best. This is a major mistake. The classroom teacher wants the substitute to maintain, as much as possible, the rituals and routines of the classroom. Deviating from what the students have become accustomed to is asking for trouble and threatens effective classroom management.
Effective classroom management includes maintaining a professional rapport with students. It is possible that a substitute is a friend, neighbor or even family member of some of the students in the classroom. It is essential that the substitute maintain a professional relationship with the students. Some students might be very familiar with the substitute and could even be on a first-name basis with him. Using a substitute teacher's first name is inappropriate in the classroom environment. A substitute should make sure that students don't feel so comfortable and familiar with her that they take advantage of her.
Classroom management is synonymous with "control." One of the best pieces of advice for a substitute (elementary, middle or high school) is to start the day with a strong tone of authority -- in word and demeanor. It is much easier to lighten up after control has been established than to try to tighten control as the day wears on and students become more comfortable with the substitute. Much of the effectiveness of the substitute is based on how well the regular classroom teacher has prepared the substitute materials. If the substitute is cognizant of all procedures and daily assignments, he can more effectively convey an attitude of confidence and control.
Sometimes a classroom visit or personal collaboration with another middle school professional helps the substitute teacher to manage the classroom more effectively. The regular classroom teacher will leave the name of an individual (teacher, coach or administrator) who can be contacted in case of an emergency or unruly students. It is important for the substitute to rely on that person if necessary -- to report an incident or to maintain control of the classroom environment. Ask this person to intervene before control is lost. Students should respond to another regular authority figure who supports the substitute.
