Dear TWiP listeners,
Have you ever wondered how TWiP shapes your understanding of science? We have! To find out more, Christina and the team are running a survey based study to learn more about how TWiP contributes to your scientific literacy and trust in science. Listen to the segment in this episode (TWiP 267) where Christina discusses the study’s aims and scope.
Anyone who listens to TWiP can participate. The survey is anonymous and we do not collect personal data that could identify you. There are no potential disadvantages or harms in taking part, other than using a few minutes of your time. You will receive no direct benefit from taking part in this study. However, the information that is collected during this study will give us a better understanding of who our listeners are, and why they choose to listen to TWiP. We can use this understanding to make TWiP even better!
This is an academic study and we aim to disseminate our findings to the wider public, including you. For example, we’ll have a conversation about the findings on a future episode of TWiP, we plan conference presentations and publication in a relevant academic journal
The project has been reviewed and approved by the University of Glasgow College of Medical, Veterinary & Life Sciences Ethics Committee. Application 200250013
