One important key concept in behaviorism is reinforcement. Reinforcement could shape and guide people to behave in a certain way. Giving students reward or punishment could encourage students to learn more or try harder. However, in classroom settings, not every student participates learning activities explicitly. Although they may have intrinsic reinforcement, those may have low chance in receiving reinforcement by their teachers (extrinsic reinforcement). Therefore, if teachers believe that providing students reinforcement could encourage students to learn better, they should consider providing reinforcement to students those who show low engagement in classroom as well in order to provide fair reinforcement to their students.

The paper below mentions how teachers concern about creating fair reinforcement in their classroom.
