摘要:Since the term citizen science emerged, projects involving citizens in science have increased in number and spread to a variety of areas. Citizen science is thus emerging as a mechanism for involving society, stimulating the population's interest in science and contributing to their scientific literacy. Furthermore, we must highlight the inherent contribution of citizen science projects to the attainment of the Sustainable Development Goals (SDGs). This paper reviews some examples of international citizen science projects and details active projects in Spain, from the perspective of both formal and non-formal education.
