This study assessed educational goals and learning outcomes in 57 citizen science projects in South Africa. Emphasising data collection as the primary objective, the findings revealed a secondary focus on environmental awareness, protection, and management, as well as education and research advancement. Notably, educational goals were often not prioritised, and formal measures for assessing learning outcomes were infrequently employed by project leaders. The study underscores the necessity for systematic approaches to evaluate the educational impacts of citizen science projects in South Africa.

We explore and discuss the diverse motives that drive science communication, pointing out that political motives are the major driving force behind most science communication programmes including so-called public engagement with science with the result that educational and promotional objectives are blurred and science communication activities are rarely evaluated meaningfully. Since this conflation of motives of science communication and the gap between political rhetoric and science communication practice could threaten the credibility of science, we argue for the restoration of a crucial distinction between two types of science communication: educational/dialogic vs promotional/persuasive.

Science communication, whether internally or to the general public depends on trust, both trust in the source and trust in the medium of communication. With the new 'ecology of communication' this trust is endangered. On the one hand the very term of science communication has been captured by many different actors (e.g., governments, PR experts, universities and research institutions, science journalists, and bloggers) apart from scientists themselves to whom science communication means different things and whose communication is tainted by special interests. Some of these actors are probably more trusted by the general public than others. On the other hand, the channels that are used to communicate science are also not trusted equally. Particularly the widespread use of social media raises doubts about the credibility of the communication spread through them.
