The document provides tips for teachers to continue and avoid in their teaching practices. Teachers should continue making eye contact with students, wearing proper attire, explaining topics thoroughly with enthusiasm, using good teaching strategies and examples, communicating well with students, having good posture and presentation skills, focusing on the topic, and giving clear instructions. Teachers should avoid making students laugh, sharing too much personal information, having a tense demeanor, saying inappropriate words to students, always being too serious, and asking questions in a way that assumes the student does not know the answer.
