What is another piece of data Ms. Rose could use to highlight instructional time loss?

Choosing the number of students who arrive late or leave early as a piece of data to highlight instructional time loss is particularly relevant because lateness and early departures directly impact the amount of time students spend in class. Instructional time is critical for student learning, and interruptions to this time can hinder academic progress. When students arrive late, they miss essential information, disrupt the flow of the lesson, and can create additional distractions for both teachers and students. Similarly, students leaving early means that they miss critical parts of the instruction, which can affect their understanding of the material and overall performance.

Other choices may relate to disruptions in school environment or general attendance but do not specifically quantify the impact on instructional time as effectively as monitoring lateness or early departures. Detention referrals might indicate behavioral issues but don’t directly correlate with instructional time loss. Attendance records show overall presence but not the nuances of classroom engagement. School assembly interruptions can affect a general learning environment but do not address individual student time loss in a classroom setting as specifically as arrivals and departures do. Thus, the focus on late arrivals or early departures provides a clear connection to instructional time lost.
