This document discusses common difficulties that teachers encounter and provides strategies to address them. It addresses large class sizes, discipline problems, mixed-level classes, homework issues, teaching exam classes, and professional development. For each topic, it outlines specific challenges and provides activities and techniques teachers can use to engage students, manage behavior, differentiate instruction, make homework meaningful, reduce test anxiety, and avoid isolation through collaboration. The overall message is that while "bread-and-butter issues are rarely mentioned," addressing these practical difficulties is important for both teacher and student motivation.
