Example
A student raises their hand frequently during class, which is generally a positiveย behavior, but it disrupts the flow of the lesson when done excessively. The teacher implementsย DRLย by reinforcing the student only if they raise their hand five times or fewer during the class period. If the student meets the target, they receive a reward such as extra free time or praise. This strategy helps the student learn to regulate their hand-raisingย behaviorย to a more appropriate level.
