The ISE Evidence Wiki prototype has launched and is being developed as an online, dynamic resource that provides evidence about the impact of informal learning experiences. The primary audience is potential and current PIs of ISE projects, and by extension, the ISE field, particularly proposal writers, project developers, evaluators, researchers, program officers, policymakers, or anybody who is in a position to provide evidence for the impact of informal learning environment experiences. The wiki consists of brief evidence summaries, allowing easy creation and editing of interlinked web pages toward a common goal of providing evidence for the impact of informal learning environment experiences. Access the wiki at iseevidencewiki.org.
