Citizen involvement in science is part of a long history of the role of the amateur in science. Research in the USA and UK suggests that citizen science has a powerful potential to support participation in and the learning of science. Increasing research has sought to explore and measure the development of 'science literacy', science identity and learning outcomes through citizen science. The scale, focus, and organization of projects has been demonstrated to influence who participates in them, the scientific achievements, and what volunteers learn. This Science Learning+ project seeks to build upon and extend the existing work in three significant ways: (1) extend the range of contexts through which existing frameworks and instruments are used and evaluated, in particular, projects that involve families, (2) examine not only the learning outcomes of citizen science projects, but also the processes through which that learning occurs and its contribution to the building of science capital. This will help in establishing better understanding of not only what is learnt but also how learning occurs; (3) develop a better theory of informal science learning through citizen science. This will advance knowledge in informal science learning.
America's adult populace has failed to keep pace with the rapid inundation of science-centric knowledge affecting nearly every facet of personal, familial, and communal life. With three out of eveiy four American adults considered scientifically illiterate, adult civic science literacy (CSL) has reached alarmingly low levels. The purpose of this research is to determine if the CSL of adults can be elevated through a renewed citizen science paradigm (RCSP)-incorporating nonformal outdoor adult education and structured experiential learning-in which volunteers conduct scientific research in an
