Abstract
During peer-led intensive events (such as hackathons and coding camps), students actively assist others to learn and, in turn, benefit from an effective learning environment. In this paper, we present the results of an observational study, having as a working setting a coding camp based on Computational Thinking (CT), to explore how peer-led coding camps can create a seed effect in young students. In particular, we analyze how a practical approach to convey CT skills motivates and effectively prepares student tutors. Moreover, we compare the previous and next edition of the camp to identify the specific contribution of the tutors. We observed that students benefit in particular from CT perspectives and develop the necessary motivation to eventually serve as tutors, creating a multiplier effect that benefits a larger number of students of future cohorts. Moreover, our results show that student tutors contributed positively to the facilitation of the subsequent edition of the coding camp.
