As a teacher, it is very responsible for you to be sensitive to the behavior of your students. I understand your current troubles, but you need to look at this phenomenon carefully.： 1. Regarding possible code words: I would suggest paying more attention to whether these exchanges affect classroom order and student relationships, rather than the specific vocabulary itself. These expressions are often time-sensitive and regional, and it is difficult to give a universal list. 2. Professional advice： -Observe behavior patterns: pay attention to whether it is accompanied by behaviors such as exclusion and isolation. -Record specific situations: objective information such as time, frequency, and students involved -Communicate with colleagues: have other teachers noticed similar phenomena? -Carry out class meeting activities: guide through topics such as "Respect education" and "Internet Etiquette" 3. Psychological support: This situation may indeed affect the teacher's sense of professional accomplishment. It is recommended that： • Share your feelings with trusted colleagues • Record your own teaching highlights • Focus on positive student interaction 4. Handling principles： ✓ Avoid over-interpreting the group language of adolescents ✓ Maintain professional boundaries and do not directly question the meaning of specific vocabulary ✓ If you need to intervene, start from the perspective of "building a respectful language environment" The "Disciplinary Rules for Primary and Secondary Education" of the Ministry of Education and the regulations of Teachers everywhere support teachers to maintain their proper professional dignity. If the situation continues or escalates, it is recommended to seek support through official school channels. It is understandable that you are troubled by this problem, but the way you choose to proactively seek a solution shows a high degree of professionalism.
