Can involvement induced by guidance foster scientific reasoning and knowledge of participants of a citizen science project?

ABSTRACT Citizen Science projects are continuously growing in popularity as they offer a unique possibility to conduct large-scale research projects as well as allow citizens to broaden their knowledge about the research topic or the process of scientific investigations. However, the benefits for participants vary, depending on the way and the amount of participants’ personal involvement in the project. In this study, we investigated whether additional guidance would improve involvement and hence lead to greater knowledge gains, higher commitment and improved scientific reasoning of participants in a Citizen Science project on birdwatching. A group receiving guidance was compared to a group which took part in the same project without receiving additional support. Results showed that both groups enhanced their knowledge about birds and their commitment to birding, while there were no significant changes in scientific reasoning. However, participants receiving additional guidance observed a higher number of different bird species and reported being able to identify significantly more species. Participation in a Citizen Science project either with or without further guidance can be seen as powerful in supporting birders at the beginning of their initial stages. Thus, both versions should be taken into account when designing future Citizen Science projects.
