Brazilian National Science and Technology Week: a case study on engagement behaviors and impacts on the public

This practice insight describes a case study in which structured observation and questionnaires (for visitors and presenters) were combined to investigate a public science event during Brazilian National Science and Technology Week (NSTW) in 2019. A very large proportion of participants (68.6% of visitors and 25 of the 31 presenters) had been unaware of the NSTW. Among those visitors who showed initial engagement, more than half progressed towards more effective engagement behaviors. The relaxed atmosphere favored the public's participation. Activities in generic locations in less favored areas are relevant to reach out to a diverse audience. Further research is recommended for critical assessment of similar events.
