The Health Sciences and Human Services Library HS/HSL at the University of Maryland, Baltimore UMB proposes a course to build skills in people to become effective citizen scientists. A team at the HS/HSL will develop an online course, breaking down citizen science and research methods into understandable components. Citizen Science, also known as Community Science, will be explored through the lens of public health, environmental health, and personal health. The course will be asynchronous and self-paced, with approximately 30-40 hours of content. It will be offered free of charge. There will be an optional citizen scientist certificate available for a small fee. The online course will be comprised of approximately six classes, each containing distinct topical units. Classes will initially be mounted on the edX platform and utilize a variety of instructional methodologies such as short lectures, animation, interviews, and slides. There will be additional resources, assignments, and evaluation tools developed. After the award period, course content will be provided to the NNLM SEA coordinators to build an NNLM Moodle LMS.
