Answer: option c continuous reinforcement schedule
Explanation: in continuous reinforcement schedule, it involves encouraging a positive or good behavior (character) when it occurs. Encouraging of good behavior can be in form of reward, reinforcement, giving gifts, cash, appreciation and in this case of the teacher, a star sticker. Children are always happy when they are noticed for their good behavior or when you show them love or credit for it. They cherish it in their heart and we want to do more. Every good act is rewarded in continuous reinforcement schedule by teachers and this will motivate or boast the child to always makes right choices. It is simple and systemic. A child who is being rewarded for good behavior will end up having that knowledge and stay good at all times because it has become a part of him.
