I want to create an online teaching portfolio on my website, and I want to post examples of student work on my blog and teaching portfolio.
What are the ethics and etiquette of posting student work online? What are the steps I should take in doing so?
I know it is standard to take out any names, but do I need to ask the student for permission if I post their assignment without their name?
I want to post student work not only for my portfolio, but also as examples for my future students for the kind of work I am expecting.
If it matters, I am in mathematics, and teach at the undergraduate level.
