This paper describes a growth mind-set intervention with Junior Cycle Coding students in a disadvantaged school in Ireland. This intervention builds on the work of O'Rourke et al. (2016) and applies findings to a computer programming setting where gamification is used to incentivise growth mind-set behaviour in students learning to code. Data revealed a large drop in the perseverance of effort with the control group while learning computer programming. Significantly, the intervention shielded the focus group from experiencing the same drop while learning to code. This research found an increase in the growth mind-set behaviour as the intervention progressed. Additionally, the study revealed that some game elements were effective at incentivising growth mind-set behaviour like perseverance, while others were less successful. These findings are important for educators to consider when they find their Coding students showing a helpless response to challenge as this research sets out a clear path to successfully incentivise persistence and changing strategy in the face of challenge.
