Open Citizen Science: fostering open knowledge with participation

Citizen Science or community science has been around for a long time. The scope of involvement in initiatives ranges from short-term data collection to intensive engagement delve into research topic together with scientists and/or other volunteers. Although many volunteer researchers have academic training, it is not prerequisite participation projects. It important adhere scientific standards, which include, above all, transparency regard the methodology and public discussion results, open educational resources (OER). Hereby, closely linked Open Science. In our contribution, we will introduce two projects, both developed within Wikimedia Fellowship Freies Wissen. top-down approach: ERGo! An Entomology Research Tool raise awareness biodiversity protection. Inclusion academia pressing social problems such as climate change are fundamentally justice issues. To facilitate early process on part people holding underrepresented identities science, develop initiative based low-cost open-source platform (ERGo!) perform technique electrical recordings insect eyes known electroretinograms (ERGs) while presenting visual stimuli. Pasadena Unified School District High students pilot ERG experiments test feasibility this large-scale initiative. With ERGo!, future Scientists contribute cutting-edge that monitors biodiversity, adaptation, health rapidly changing environments caused by monocultures, pesticides, change. bottom-up cultural collection. A regional knowledge curation. We catalogued 18th century German magazine ‘Die Gartenlaube’ (in Wikisource) bibliographic metadata Wikidata project called Datenlaube’. collaborative approaches methods produce sets about historical knowledge. concept ‘Open Science’ offers methodological baseline practises fields digital humanities. Scanned documents structured revealed access historic collections. Through platforms 'Die Datenlaube' creates possibilities edit entries, design own investigations, OER. Based elaboration rather different projects (natural sciences, pupils vs citizens, bottom-up), discuss similarities hence challenges lessons learned using developing elements mutual learning. Furthermore, conclude focusing opportunities resulting integration societal expectations vice versa.
