Daily E-Mail with Campus Activities
The university will now send all students a daily e-mail containing information about campus events and activities. Rather than getting information about activities once a week in the campus newspaper, students will get the information every day, thus ensuring that it is always up-to-date. According to the university spokesperson who announced the plan, “For all of us now, e-mail is part of our daily lives. Students in particular have become used to relying on e-mail and the Internet for most communication, so this is a logical change that will benefit everyone.”
问题

Questioning Awareness of Effect

Questioning Awareness of Effect
When a student engages in disruptive behavior in the classroom, it negatively impacts both the teacher’s ability to teach and other students’ ability to learn. One way a teacher can correct disruptive behavior is by questioning awareness of effect. With this technique, when a student disrupts the class, the teacher asks the student a question that draws attention to the negative effect of the student’s behavior. The teacher then does not wait for an answer, but immediately continues teaching. By thus simply drawing attention to the effect of the student’s behavior, the teacher can often lead the student to discontinue the behavior.
问题
Explain how the example from the lecture illustrates the technique of questioning awareness of effect.
