Palloff, R.M. and Pratt, K. (2008). Assessing the Online Learner: Resources and Strategies for Faculty. New York: Jossey-Bass.
This is not a new book, but it remains a constant source of inspiration when faculty need to find creative ways of assessing learning for online students. Practical and full of case studies and examples, the book focuses on the design and use of authentic assessment, including peer assessment, project based work and collaborative task-based assessment. Given that assessment times are fast approaching, it is a helpful reminder of what you can do that will help students see assessment as learning and for learning.
