摘要：Formative assessment has been shown to improve medical student performance and retention, but many learners lack access to formative assessments because faculty members have limited time to create such resources, and acquiring existing commercial review banks is expensive. In response, we developed a collaborative learning platform for medical student self-assessment called Osmosis (http://osmosis.org/). Osmosis is a web- and mobile-learning platform that provides free access to thousands of crowd-sourced, high-yield practice questions and explanations. The quality of these questions and resources is enhanced through a unique social rating and commenting feature. During the first year Osmosis was launched at the Johns Hopkins School of Medicine in January 2012, approximately 250 students in the first and second year classes spent over 2,400 hours answering more than 5,000 questions close to half-a-million times (∼2,000 questions answered/student). In addition, over 1,000 Creative Commons-licensed images and YouTube videos have been shared. Usage data and reception by students indicate that the platform fits well into busy schedules and that participants value its role in promoting collaboration and self-assessing knowledge gaps. We are currently developing additional features for the Osmosis platform related to knowledge retention and curricular design. Since the vast majority of questions and resources on Osmosis are shared under non-restrictive licenses, such as Creative Commons, we are making Osmosis available to peer institutions. It is our hope that more students and faculty members will benefit from, and contribute to, the Osmosis library.
