This practice insight examines how science mediators facilitate students' appropriation of scientific knowledge. It focuses on the Science of Superheroes initiative, which is an informal education curriculum activity designed to engage middle school students in exploring environmental challenges through the creation of a superhero. Using Bruner's scaffolding framework, we analyze how mediators' interventions shift between scaffolding functions, depending on the task. While the appropriation of scientific knowledge is supported by questioning and information-sharing strategies, the creative phase sees an increase in proposal-based scaffolding, which struggles to counterbalance students' reliance on magical thinking. This cognitive tension highlights the challenges of integrating scientific knowledge into a fictional narrative. Our findings highlight the need for science mediators to refine their questioning techniques, foster greater self-regulation among students, and enhance their ability to meaningfully incorporate scientific concepts into their superhero designs. Our study contributes to ongoing discussions on the professionalization of science mediation and offers new insights for mediator training.

The aim of this paper is to analyze the impact of Comics & Science workshops where forty-one teenagers (designated Trainee Science Comic Authors [TSCAs]) are asked to create a one-page comic strip based on a scientific presentation given by a PhD student. Instrumental genesis is chosen as the conceptual framework to characterize the interplay between the specific characteristics of a comic and the pieces of scientific knowledge to be translated. Six workshops were conducted and analyzed. The results show that the TSCAs followed the codes that are specific to the comic strip medium and took some distance with the science integrity. Nevertheless being involved in the creative process allowed them to understand the reasons for certain choices of science illustration or storytelling. This approach can foster the emergence of a critical mind with respect to reading science stories created in other contexts.
