This document discusses principles of effective time management for teachers. It identifies several key principles: 1) Never manage time alone - consult supervisors and schedules to accomplish competencies. Distribute time equally among tasks. 2) Be flexible - unexpected events may occur, so have backup plans. 3) Learn not to be agitated by immediate demands - some tasks like student grades cannot be delayed. It also recommends establishing non-negotiable tasks, discarding low-quality activities, allowing for some "well wasted time" like viewing student work, and learning to say "no" to demands that interfere with lessons. Effective time management brings positive change for students.
