What is the term for the ability to handle multiple classroom events simultaneously according to Kounin?

According to Jacob Kounin, a prominent educational psychologist, Overlapping refers to a teacher's ability to effectively handle multiple classroom events or issues simultaneously without losing the flow or momentum of the main instructional activity. This skill is a hallmark of effective classroom management. For instance, a teacher demonstrating overlapping might be working with a small group of students while simultaneously noticing and addressing a minor disruption across the room, perhaps with a glance or a quiet word, without interrupting the small group's task. It's about maintaining awareness and intervention across the entire classroom space. This differs from 'With-It-Ness,' which is the teacher's awareness of what's happening in the classroom, and 'Momentum,' which relates to the pacing and flow of lessons. Overlapping ensures that minor issues are addressed promptly and efficiently, preventing them from escalating and thereby maintaining student engagement and a productive learning environment.
