Final answer:
Excessive planning can make it harder for a teacher to be present and responsive to students, leading to a less fluid and dynamic classroom environment that may limit student engagement.
Step-by-step explanation:
One con of planning too much is that it can make it harder to be present to students in the moment. Overplanning can lead to a rigid classroom environment where the teacher is so focused on the details of the plan that they may miss spontaneous teachable moments or the opportunity to address students' immediate needs and questions. This approach can restrict the natural flow of the classroom, causing the class to feel less fluid and more mechanical, potentially stifling student engagement and creativity.
Excessive planning may also lead to a decreased ability to respond to the dynamic nature of classroom interactions. For example, if unexpected topics or interests arise during a class discussion, an overly planned approach may not allow the flexibility to explore these new directions, which can be valuable for learning and student engagement.
