The document discusses public assessment and student performance. It describes three case studies of university courses that incorporated public or shared assessment components, such as Twitter essays, music blogs, and contributing to Wikipedia. For each case study, it provides the course learning objectives and types of assessment. It also includes comparative grade data and examples of student feedback, which was generally positive about the value of public assessment. The document argues that making student work publicly available and assessing work intended for broader audiences can motivate students and shift the focus of feedback to a more social practice.
