This resource allows students to learn while writing, through peer evaluation, and then through a follow-up self-assessment. Student writing is then available for use to optimize instruction according to how students think and the difficulties they encounter. I found that this resource improves learning - refer to my published a paper on the impact CPR writing had on learning physiology http://advan.physiology.org/cgi/content/full/26/3/174?
Training is needed. Contact the authors, who are then willing to find a way to provide free access to this resource, once the instructor has received the needed training.
