NOVA: Keep It Cool - User Testing Dataset

This dataset contains the results of a user-testing session conducted for NOVA: Keep It Cool, an educational game designed to support the understanding and discussion of energy systems, energy-related choices and their consequences. The dataset includes responses from 23 volunteer participants aged 12-25 who took part in a facilitated pair-based testing session on 13 August 2026. Three adapted post-experience questionnaires were used to investigate usability and learnability, cognitive workload and frustration, and user experience and perceived educational value: a SUS-inspired questionnaire, a NASA-TLX-inspired questionnaire and a UEQ-inspired questionnaire. The dataset consists of three CSV files linked through anonymous participant IDs, together with a README describing the testing procedure, questionnaire variables, descriptive statistics, exploratory cross-questionnaire analysis and methodological limitations. The results supported the continued development of NOVA: Keep It Cool and the retention of 12-16 years as the project’s primary target age range.
