Peer production projects involve people in many tasks, from editing articles to analyzing datasets. To facilitate mastery of these practices, projects offer a number of learning resources, ranging from project-defined FAQsto individually-oriented search tools and communal discussion boards. However, it is not clear which project resources best support participant learning, overall and at different stages of engagement. We draw on Sørensen's framework of forms of presence to distinguish three types of engagement with learning resources: authoritative, agent-centered and communal. We assigned

This study examines the relative efficacy of citizen science recruitment messages appealing to four motivations that were derived from previous research on motives for participation in citizen-science projects. We report on an experiment (N=36,513) that compared the response to email messages designed to appeal to these four motives for participation.

To quantify how much of the night sky has been lost to light pollution, students in grades 3-8 compare their backyard view of Orion to six star charts of the constellation with varying limiting magnitudes.

Beforehand, all teachers integrate some aspect of the topic in their regular classroom instruction. The website offers supporting lessons, resources, and ideas for teachers and families alike.
