Designing Online Experiments: Citizen Science Approaches to Research Abstract New information technologies allow for new modes of data collection, provide unparalleled computational resources, and facilitate long-distance collaboration. Programs like Galaxy Zoo, Fold.It, and ReCAPTCHA demonstrate the power of recruiting online volunteers as participants and contributors to research. Platforms like Project Implicit, SciStarter, and Volunteer Science confirm that a wide range of social scientific research can be conducted with volunteers in online laboratories. This workshop will explore the opportunities, challenges, and limitations of online experiments and build a community of scholars performing online experiments. A group of scholars with wide-ranging experience in this area will discuss existing and emerging approaches to online experimentation. Participants will learn about designing and running online studies, and recruiting and managing subjects. Participants will then be given access to the Volunteer Science research platform (volunteerscience.com) where they will work with researchers to develop, test, and deploy their own online studies.
