Classroom expectations and policies

This is a work- and discussion-based class, and attendance is required. Your grade will be based on demonstrating your achievement of the course outcomes in class, and therefore participation is the only way to succeed. If you must miss a class, give me as much notice as you can and make a plan with me for how to make up your participation.

My classes are always safe space. The Advocates for Youth define a safe space as:

A place where anyone can relax and be fully self-expressed, without fear of being made to feel uncomfortable, unwelcome, or unsafe on account of biological sex, race/ethnicity, sexual orientation, gender identity or expression, cultural background, age, or physical or mental ability; a place where the rules guard each person's self-respect and dignity and strongly encourage everyone to respect others.

The policies of CGCC also apply.

It is important to me that students come to my classes eager to learn; if there is something in your life making it difficult to participate, please come to me. I will do what I can to make sure you can find the resources you need outside of class, in order to foster an energetic community inside of class.
