What should not be done to students before the end of the period in a well-run classroom?

In a well-run classroom, students should not be dismissed before the end of the period. Dismissing students prematurely can disrupt the flow of the lesson and result in incomplete learning experiences. It can also signal to students that the structure of the class is not being adhered to, potentially leading to a lack of respect for classroom rules and authority. Properly managing dismissal ensures that students receive the full benefit of their instructional time and helps maintain an environment conducive to learning.

Additionally, the other actions mentioned—distracting, interrupting, and reprimanding—are behaviors that often detract from the learning environment but may be employed at times as necessary responses to maintain order or refocus student attention. However, a key tenet of classroom management is that students should feel secure and know that they can expect a consistent conclusion to their class sessions. This predictability fosters a positive learning atmosphere and reinforces closure on lessons taught.
