Community Engagement 社区参与

We expect everyone to be mindful of what they say and its potential impact on others. The goal is to have respectful discussions that do not violate the community space created for these conversations. Here are some productive ways to engage in this course: 
我们期望每个人都注意他们所说的话及其对他人可能产生的影响。目标是进行尊重的讨论，不违反为这些对话创建的社区空间。以下是一些参与这门课程的富有成效的方式：

保持您的热情积极：在回复讨论论坛帖子时，请就所讨论的内容发表看法，而不是针对发帖人。避免使用全部大写字母、过多的感叹号或攻击性语言。

Note regarding “study groups” outside of the platform: While learners are encouraged to interact with one another using communication tools offered within the learning platform, note that any study groups formed outside of this platform, such as over social media or communication applications and websites (e.g., WhatsApp) are not affiliated, endorsed, or moderated by the University of Michigan. If you receive an invitation to an outside study group mentioning the course and claiming to have any official connection to U-M or individual instructors, please exercise caution as this may be an attempted scam.
关于平台外“学习小组”的说明：虽然鼓励学习者使用学习平台内提供的通讯工具相互交流，但请注意，任何在平台外形成的学习小组，如社交媒体或通讯应用和网站（例如 WhatsApp）等，均与密歇根大学无关、未获认可或未受监管。如果您收到邀请参加提及课程并声称与 U-M 或个别讲师有官方联系的校外学习小组，请谨慎行事，因为这可能是诈骗尝试。
