Praise and ignore approach
teachers ignore inappropriate behaviors displayed by an individual while praising the appropriate behaviors of others.
o Ex: teacher may ignore a student who blurts out the answer to a question while praising the other students for raising their hands and being patient.

teacher may increase one behavior of students by providing an activity as reinforcement rather than giving tangible rewards

shaping &successive approximation-
used when behavior is not currently being displayed and therefore cannot be reinforced. o If a student never brings a pencil or paper to class the teacher doesn’t have the opportunity to reinforce the behavior because it doesn’t occur.
Positive Practice-
teacher has the student perform the right or appropropriate behavior,
o Students may write words they misspelled to practice the correct way to spell them.
o Teacher may have students who run down the hallway return to the end of the hall and practice walking— decreasing the likelihood that student will do it again.
