Last month we had our first meeting with our participant panel. Nine (old) participants seized the opportunity to think along with us about the study and research questions. The topics we discussed were: how we can activate our participants to use the citizen science platform ‘Ik onderzoek mee’; what the right balance is in contact frequency; how a participant event should look like; how we can optimally manage expectations with regard to time investment. Overall we can say that our participants are very satisfied. We will incorporate the useful feedback we received from the participant panel.
