Summary
Research indicates that classroom interruptions, even brief ones, significantly disrupt learning, resulting in substantial cumulative time loss. This loss isn’t just the interruption itself but also the time needed for students to regain focus. The discussion highlights how seemingly minor interruptions, like a teacher checking in, can have a surprisingly negative impact. Furthermore, it emphasizes the importance of minimizing self-interruptions by teachers through mindful planning and restraint. Ultimately, the video promotes awareness of this often overlooked issue, suggesting strategies for reducing interruptions in educational settings.
Time-stamps
- [0:47-2:22]: A study from Matt Craft and his colleagues found that interruptions and disruptions in high school classrooms resulted in a significant loss of learning time. They estimated that it added up to 20 days of lost learning time per school year. While this may seem excessive, it is important to consider that the lost learning time is not just the duration of the interruption itself but also the time it takes for students to refocus and get back on track after the interruption. For example, a student coming to the door to ask a question might only take 20 seconds, but it could take students several minutes to regain their focus and remember what they were working on.
- [2:23-3:42]: This segment highlights personal anecdotes about the impact of task switching on productivity. Cal Newport’s concept of “deep work” is mentioned, emphasizing the negative effects of interruptions on concentration and cognitive flow. The speaker shares their own struggle with task switching, particularly when writing, and mentions the use of apps that block distractions to help maintain focus.
- [3:43-5:30]: This segment discusses the unintended consequences of well-intentioned interruptions in schools, such as a headmaster frequently checking on classrooms. While the headmaster’s actions are meant to ensure everything is running smoothly, these brief interruptions can disrupt student focus and lead to lost learning time. The anecdote highlights the importance of being mindful of the potential impact of interruptions, even those that seem minor.
- [5:31-6:31]: Teachers can also be a source of interruptions in the classroom. The speaker acknowledges their own tendency to interrupt students during practice tasks with unnecessary instructions or reminders. This self-awareness led the speaker to consciously work on reducing their own interruptions by “zipping it” and only intervening when absolutely necessary.
Overall, the video emphasizes the significant impact that seemingly small interruptions can have on learning and productivity. It highlights the importance of minimizing interruptions and being mindful of the “wake” they leave behind.
What are the key implications for teachers in the classroom?
- Interruptions in the classroom, even those that seem brief and well-intentioned, can result in a significant loss of learning time. A study cited in the source found that interruptions and disruptions can lead to the equivalent of 20 school days per year of lost learning time. This is because interruptions not only consume time directly but also cause students to lose their train of thought and require them to spend time getting back on track.
- Teachers should be mindful of both external and internal interruptions. External interruptions include things like announcements, visitors, and students coming to the door. Internal interruptions are those caused by the teacher themselves, such as interrupting students’ work to provide unnecessary guidance or commentary.
- Teachers should strive to create a classroom environment that minimizes interruptions. This could involve strategies such as establishing clear routines and expectations for student behavior, minimizing unnecessary announcements and transitions, and being mindful of their own tendency to interrupt.
- Teachers should be particularly aware of the impact of interruptions during focused work or discussion. When students are engaged in deep thinking or collaboration, interruptions can be particularly disruptive. In these situations, it is important for teachers to be especially vigilant about minimizing distractions.
- The concept of minimizing interruptions applies to individuals as well. The source describes the negative impact of task switching on productivity, using the example of checking email while writing. This highlights the importance of creating focused work time for both teachers and students.
