Natural rates of teacher approval and disapproval in the classroom.
Sixteen classroom observational studies were conducted to determine natural rates of teacher verbal approval and disapproval in the classroom. Rates of teacher verbal approval and disapproval were measured by the Teacher Approval and Disapproval Observation Record (TAD) over Grades 1 through 12. Teacher verbal approval rates dropped over grade, with a marked drop after second grade. In every grade after second, the rate of teacher verbal disapproval exceeded the rate of teacher verbal approval. These rates are interpreted in terms of reinforcement theory.
