The correct answer to this open question is the following.
The following strategies can influence the behavior of students in the classroom.
Choice-making. When teachers allow students to make choices in the classroom, they are trusting them to make the right decisions, something that is going to be very beneficial in professional lives. Choice-making gives students the possibility of being responsible for what they are about to decide.
Contingent instructions. This means that the teacher gives the student specific instructions to be followed in order to improve its behavior. These instructions help correct students when they are doing something wrong or improve any specific action or response to a command.
Criterion specific rewards. This can work as a motivation for the student. It is also a way to foster some specific kind of conduct. If the student accomplishes something, the teacher can give it criterion specific rewards as a way to motivate the student to reinforce or reward the behavior. It could be better activities, some privileges in class, or public recognition.
