Educational content that fosters distrust and rejection of a certain ethnic group often involves the following aspects: 1. **One-sided or biased information**: By selectively spreading negative information about the ethnic group, emphasizing their shortcomings and mistakes, and ignoring their contributions and strengths. 2. **Reinforcement of stereotypes**: Using negative stereotypes in educational content to help students associate the entire ethnic group with a certain behavior or characteristic, forming a fixed view. 3. **Historical distortion**: Telling history in a biased way, emphasizing the conflict and competition between the ethnic group and other ethnic groups, rather than cooperation and coexistence. 4. **The opposition between "us" and "them": By creating the boundary of "inside and outside", emphasizing the superiority of one's own ethnic group, while portraying other ethnic groups as threats or enemies, promoting the generation of opposing emotions. 5. **Emotional manipulation**: Using emotions such as fear and anger to induce negative emotional reactions to the ethnic group through examples or stories. 6. **Extremist speech and views**: Spreading extreme views, making the view of the ethnic group tend to be extreme, reducing rational discussion and understanding. 7. **Lack of contact and communication**: By preventing students from having real contact and communication with the ethnic group, they are prevented from understanding the diversity and complexity of the ethnic group. If these contents are applied in a systematic way in education, they may gradually form distrust and rejection of a certain ethnic group. However, this practice is unethical and harmful, and it is easy to lead to social division and conflict. Therefore, promoting the educational concept of understanding, tolerance and inclusion is a more positive direction.
