It is inevitable that teachers will be mixed with personal emotions in the process of teaching students. The following are five aspects:

1. Emotional contagion: As class cadres and role models, teachers often show positive, confident and pragmatic emotions in teaching. However, if the teacher is depressed or anxious, it is easy to convey this emotion to the students, which will affect the students' emotional state and thus affect the learning effect.

2. Example behavior: Teachers are also one of the representatives of students' example behavior. Their behavior, words and deeds, emotional expression, etc. Will be observed and imitated by students. If teachers show too many negative emotions and behaviors in daily teaching, it will have a bad influence on students, and even make students mistakenly think that these behaviors are correct.

3. Influence of teaching effect: Personal emotions appear in the teaching process, which easily affects teachers' evaluation of students. Students may be overestimated when they are in high spirits and underestimated when they are in low spirits, thus affecting teachers' objective judgment on students' learning status and teaching effect.

4. Ability to deal with problems: Teachers with unstable emotions will be influenced by personal emotions and take too radical or too weak measures when dealing with students. Of course, this deviation may also lead to the deterioration of the relationship with students.

5. Personal image damage: As a role model for students, teachers' personal emotional out of control or emotional behavior will directly affect their image in the eyes of students. If you deal with problems emotionally, students will think that teachers lack professionalism and stability, and their respect and trust will also decline. This will have a negative impact on teachers' professional honor.

In short, as a teacher, we should always keep a good attitude and correct emotional handling methods, so that our emotions will not affect students' learning effect, nor will they hurt our image and professional image.
