B.F. Skinner developed the theory of operant conditioning which holds that behaviors are shaped through reinforcement. He found that mice would press a lever if it resulted in a food pellet reward. Skinner also conditioned pigeons' behaviors using rewards. Operant conditioning uses positive reinforcement to encourage desired behaviors in students. Teachers can reward behaviors like attention, homework completion, and correct quiz answers to shape student learning. Both with and without technology, operant conditioning positively reinforces students and builds their confidence.
