What feature allows teachers to reward students in the AR program?

The correct answer highlights the importance of goal-setting and recognition systems within the AR program, which actively encourages student motivation and engagement in their reading. This feature allows teachers to customize rewards based on individual quiz performance, fostering a supportive learning environment where students are recognized for their achievements. Setting goals can help students strive for improvement and feel a sense of accomplishment, which is essential for building confidence and a love for reading. Such recognition can take various forms, including certificates, badges, or other incentives that celebrate their progress and efforts in reading.

While the other options may involve components of a classroom environment, they do not specifically focus on the AR program's distinctive feature of personalizing rewards based on reading goals and quiz results. Automatic grading assists in evaluating performance but does not inherently reward students. Providing prizes for top scores may not promote a broader culture of achievement and motivation for all students, while assigning group projects is not directly tied to the AR system's mechanisms for recognition and reward based on individual performance.
